Note: The Timbren Axle-Less suspension system may require additional support on your trailer. If your trailer does not have a crossmember above the spot where you want to install the Timbren system, you may need to reinforce the frame. You can accomplish this three ways. First, you can retrofit the trailer with a crossmember. Second, you can build out the trailer frame. Third, you can use standard, 2-inch steel tubing to connect the 2 Timbren suspensions together using the built-in square hole on each unit.
Ride on rubber with Timbren's Axle-Less trailer suspension system. This one-of-a-kind suspension consists of two separate units, each containing rugged steel arms and two strong, hollow rubber springs. Overall, the system safely and effectively absorbs road shock, minimizes trailer bounce and rattle - regardless of load size - and helps to protect your trailer's components and cargo. Built-in camber and toe-in keep your trailer tracking straight to minimize tire wear. Integrated hangers attach to your trailer's frame. And 2-inch holes make it easy to reinforce your trailer's frame by adding standard, 2-inch-square steel tubing (if needed).
The Axle-Less independent suspension system replaces your trailer's existing leaf spring suspension and can eliminate the need for an axle. The independent action of the suspension reduces roll when your trailer is cornering and allows you to maximize ground clearance and minimize deck height. Your trailer can have the same side-to-side clearance as your tow vehicle. And the low deck height makes it easy to load cargo from either the rear or the side.
Because you're riding on rubber, your trailer will ride smoothly and comfortably, whether you're navigating rocky terrain or highway asphalt.
Timbren Axle-Less Suspension Parts
- The AEON progressive-rate main spring supports the weight of your trailer and cargo and easily absorbs road shock. It is constructed of heavy-duty, hollow rubber.
- The rebound spring minimizes trailer bounce, rattle and bottoming out. It keeps the suspension under constant tension and ensures that the main spring compresses and expands in a controlled fashion. And it delivers a smooth, stable ride - regardless of how much cargo is on the trailer.
- The trailing arm and integrated hanger attach the suspension to the side and bottom of the trailer frame.
- The control arm carries the spindle and the hub. It pivots on strong, long-lasting urethane bushings that never require lubrication.
- The EZ lube spindle is simple to grease. If damaged, it can be removed and replaced, saving you both time and money.
- The hub is not included with this model.
- The built-in square hole accepts standard 2-inch tubing. If there is no crossmember above the suspension, you can easily add support to your trailer's frame by inserting 2-inch steel tubing through the hole on each suspension unit and then bolting the tubing into place.
Timbren Axle-Less Suspension versus Leaf Springs
The Axle-Less suspension's progressive spring is a definitive upgrade over leaf springs. Although leaf springs deliver a stable ride when supporting a load, a trailer with leaf springs will bounce and rattle when it's empty or supporting a light or off-center load. On the other hand, your trailer can bottom out on bumpy roads if the load is too heavy. The AEON progressive-rate springs of the Axle-Less suspension always deliver the same reliable performance, no matter the load size. As more weight is added to the trailer, the springs compress and become stiffer, offering more support for heavy loads. And because they rebound more slowly than leaf springs, the AEON springs do a better job of absorbing road shock, thereby keeping your trailer from bouncing and rattling when you're carrying a light load. So with this versatile system you will enjoy a smooth ride whether you're towing an empty trailer or a hefty load.
Unlike leaf springs, Timbren's Axle-Less suspension units operate independently of one another. Each spring activates only when needed. This reduces roll and delivers top-notch performance, even when you're hauling off-center loads. When your trailer with leaf springs takes a turn, one side of the suspension compresses and takes on more weight, and the other side becomes looser and bounces. This causes rattle and can make the trailer lean to one side. But when your trailer with the Axle-Less suspension takes a turn, one side compresses and becomes more rigid to absorb the weight, and the other side expands to normal height to help steady the load and minimize bounce and rattle. The load stays better balanced, even if it is off-center.
Timbren Axle-Less Suspension versus Torsion Axles
Timbren's Axle-Less trailer suspension system is a great alternative to torsion axles. While both systems allow either side of the trailer's suspension to operate independently, only Axle-Less suspensions are actually separate units. Torsion axles still require a bar that spans the bottom of your trailer, whereas Timbren's system can eliminate the need for a thru axle - giving you the same amount of ground clearance from the front of your trailer to the rear. It also allows Axle-Less suspensions to fit any trailer width - unlike torsion axles, which have to be fitted to an exact frame width.
Axle-Less suspensions operate in a smoother, less stressful manner than torsion axles. Torsion axles use a twisting motion, where the bar inside the axle tube rolls against rubber cords or a rubber wall to create compression and resistance. The up-and-down motion of the main spring and the side-to-side motion of the rebound spring in Timbren's Axle-Less suspension work together to provide smooth, consistent compression - with no twisting - that results in a better ride and less stress on the suspension's components.
Installing the Timbren Axle-Less Suspension
Whether you are building a trailer or retrofitting your existing trailer with the Axle-Less system, you must make certain that the trailer's frame is both perfectly square and sturdy enough to support a heavy load without the aid of a thru axle.
There are three ways to install the Axle-Less suspension. The easiest method, which is recommended if you are replacing axles on your trailer, is to install a piece of 2-inch-square tubing (sold separately - available at most weld shops) through the integrated hole in the Axle-Less suspension. Then all you need to do is bolt the suspension to the side of the trailer's frame with three bolts (not included).
The second option for installation is to fabricate an inboard extension plate that attaches the trailer's frame to the Axle-Less suspension.
The third method of installation is to bolt the Axle-Less suspension's hanger to the trailer's frame and to an existing crossmember that is in the area where you want to install the suspension.
With both the second and third options, you must use three bolts to attach the suspension to the side of the frame. And you also have to use two or three bolts to attach the suspension to the bottom of the frame extension, or crossmember. Both the second and third methods of installation will eliminate the need for a thru axle and provide the most clearance.
Timbren's Axle-Less suspension units should be installed directly across from one another. Before mounting the units, measure back from the coupler and mark the frame to make sure that the two distance measurements (A and B) are within 1/8 inch of each other. Then you can drill holes through the frame and attach the hangers with Grade-5, half-inch bolts (not included).

Timbren Axle-Less Trailer Suspension System Test Course
Video Transcript for Timbren Axle-Less Trailer Suspension System Review
Today we're going to be taking a look at, then we'll show you to install the Timbren Axle-less Trailer Suspension System. These are available in multiple configurations to fit most applications. Just check our website out for details. Today specifically we're going to be using part number ASR3500S05. This is a spindle only configuration for 3,500 pound axles. With the spindle only configuration we're going to be reusing our bearings, we're going to be reusing our brakes and our drums.
You may want to pick up some new seals if you're going to go this route. We also have the full kits available with the brakes, the drums, and everything that you'll need. The Timbren Axle-less Suspension is an excellent, excellent product. You can tell an immediate difference as soon as we start hauling our trailer with the items installed. It's much, much quieter, much smoother, you don't feel the weight in the truck nearly as much as you did with that standard suspension. You can see as we're cornering there's no transfer of weight.
They're working independently to keep our trailer nice and level. Here's what our kit's going to look like installed. This axle-less suspension system from Timbren is kind of a solution for all that noise and everything that we typically get with our trailers; real rough ride. Now, they use 2 rubber springs essentially, they're Aeon rubber springs. We've got our larger one here in the back. This is the main body of the system, and as we load it more and more and more it constantly kind of adapts to that to give us just the ride of support that we need. To keep this constantly under tension so we don't have to ever worry about a lot of that rattling and stuff, we've got a rebound spring right here in the front.
These are designed to work with really any style of trailer frame, no matter of the thickness here. Depending on the application if you've got a really wide trailer, well then you're just going to put the 3 bolts in the side, 3 bolts up through the bottom. We're dealing with a little bit narrower angle channel here, so what we've done is we've put the square tube across the front. You could also design a bracket to go on the side, if you wanted like a gusseted bracket. There's a lot of options out there. We went with the spindle only design.
It's really heavy duty, too. You can really tell about the quality that they've put into the design of it. Going to have a black powder coat finish on all of our surfaces and this real nice thick steel fully welded around all of our points with reinforcement gussets right where we want them. You can just tell it's a really well built system. Another advantage that we're going to see with the axle-less suspension is going to be increased ground clearance. We don't have that axle that typically hangs down here lower. Even with us using the cross tube design or the cross bracing design, it's tucked up right underneath of our trailer. It's even up higher than what our cross members are here for our flooring, so really tucks it up. Then this area down here, you can see smooths off. The axle-less suspension system can also help us with getting our deck height of our trailer where we want it. These are available in both drops and lifts. One of the added benefits that we get out of this axle-less system is that we're not tying this side of the trailer to that side of the trailer with one of those through axles that are going to go right through down here where all our movement's going to actually take place. This allows these to work independently of one another. If we hit a bump on that side it doesn't transfer all the way over here and then cause this side to go too. Now, they've set this up with tow and camber adjustments aligned 00:04:02 already, so we should have great tire wear as we track down the road. However, if need be they do provide us with some nice alignment shims here if we do want to change it up a little bit, or maybe our trailer's frame wasn't exactly square. Another great thing about the Timbren Axle-less Suspension set up is that they use urethane bushings here at our pivot point. It's going to be very very long lasting. It's going to keep everything nice and tight, and we don't have to worry about lubrication. To begin our installation we need to get our factory axle out. Now if you are going to reusing hardware off of the original axle it's best to do it when it's still on the trailer. That way you're not fighting the roll. All right, now you'll notice here on the frame of our trailer, this is our rear spring perch. We've removed the front to allow room. You may have to do that on yours, and there was a couple welds here and then here that kind of stuck out on the frame rail. We've gotten rid of those. Just use a grinder, get it nice and clean. We want a nice smooth surface for this to mount up against. We're going to mock it up now just by bringing this edge up and letting it sit on our trailer. You can see the 3 holes we're going to use for attachment. Now the key to getting this set up properly, you can see we've got some plumb bobs here. Basically it's just a string with a nut tied to the end of it. We've gone off of both of our spindles here in the same location, and then we've gone from the center of our coupler in the front so we've got them at 3 locations. Now we're going to measure from that string back to this string, and then we'll measure from the front over to the other side. It's very important for us to have these within an 1/8 of an inch. What this means is that we've got the perfect triangle from the coupler back to each of our spindles. We won't have to worry about any kind of side tracking. It's going to keep our trailer running straight behind us, and it's going to make sure that we're getting proper tire wear. Adjust as necessary. We want to make sure if you're using plumb bobs that your trailer's level. After that it's just a matter of getting them lined up to where they're going to be just right. We'll measure, mock it up, measure, mock it up, and then once we have it right where we want it we can get our holes drilled. Now we want to take a punch and I'm going to mark the middle of my rear hole. Then we can start stepping up to a 1/2 inch hole diameter is what we want to end up with. We start with just an 1/8 inch and then kind of move up as we go. All right, that created a little too much movement, so we want to get this hole drilled perfectly to get that suspension out of the way and get our hole drilled out. We'll bring it up, slide our bolt through the hole there, and then put our hardware on the inside. That's going to do a good job of holding that in place while we get the rest of our holes marked. I'm going to use a jack stand again here just to apply some upward pressure. I'm going to tighten this nut down temporarily. That's going to draw it right over into position we want to make sure it's pressed up firmly all the way in the front. We don't want any kind of gaping between the top of our enhancement here and the bottom side of our trailer. Now we can use our center punch or our 1/2 inch bit here and get the center of our holes marked. You see I've already mocked up what would be the passenger side of the trailer. Anything I do on this side, I'll do the exact same thing on the other side. Now we're ready to get these pulled down and we'll get our holes drilled out. All right, now with those holes drilled out let's get our suspension back up into place here. What I want to do is just get these 3 started and I'm going to get them snugged down. This isn't a permanent mount, so we don't want to torque them all down. We've got to measure for that cross tube. We're going to be using this opening here for a 2 inch by 2 inch cross tube section that's going to give us additional strength. There's a few options on the additional strengthening process that you can check out in the instructions. That's mainly for just like the trailer that we've got here, just your simple utility trailer that just has an angle iron frame. If you see channels and things like that, typically once we're putting these on the heavy-dutier trailers there's going to be plenty of thickness in the frame. You really don't have to worry about having that cross tube. Now to figure out how long of a pipe that we're going to need here we're just going to measure inside to inside. There's going to be a couple little lips there. Right here there's a little bit of a lip. We just want our pipes to sit just inside of those, and we'll want our square tube to fit right inside of that. Now with our pipe cut to size all we'll need to do is slide it in all the way across, and we'll want to make sure that it engages our other side as well. All right, that's held in place there kind of by those little lips we saw in each end. We need to get our bolt holes here marked so we can drill our holes and install our hardware. Those should be marked so let's pull our tube back out of there, get those holes drilled, and we can put it back in. Now we can get our center punches taken care of here. Just like before we'll just step up our bit size as we go, makes it a little bit easier. Now with the tube back in we'll take our hardware, got kind of a tight squeeze here but we're just going to place that through. Place that flat washer inside of there on the bolt, then we need to get our nut started. One of these little flexible magnets is a really good way that bolts quite a ways back in there. If you've got a different method that works for you, great. My fingers won't reach in there. Maybe a pair of needle-nose you could get to work in there. These little magnets are pretty readily available and pretty handy to have, so that would be my recommendation. We'll just leave that one loosely installed. Now we're going to take our other bolt, we want to place it through both of our holes but we don't want to have it poked all the way through. What we're going to do is have that stay there as we get our spindles torqued down, as we get our brackets to our frame torqued down. Then we'll torque down our inside bolt, then we'll be able to get to this and torque this down. We'll just at that point either thread it in by hand or with a wrench, put our stuff on it and get it torqued. If we we're to leave this out completely so we could get to that back bolt, it's likely that our holes would then be slightly misaligned and it would be real difficult to get it in. Now we want to look in the instructions and find our torque specifications and we want to go through and torque everything down in the appropriate order to those specifications. I had these pretty snug when we we're doing the install just so we wouldn't have to worry about any movement or anything with the spindle. With those done we'll move up to the 3 here in the side. Once those are properly torqued we'll go to the ones that we've got inside of our tube. With everything torqued down that's really all there is to the install. I would here on this cut piece of tubing, just a little bit of black spray paint there. Just kind of seal that up, prevent any rusting there. Then, depending on your set up if you're using, if this is on a braking axle then you'll put your brakes back on your flange and then rebuild your hub per the instructions. If this is on a lighter-duty trailer and if you don't have brakes then you're just going to rebuild your idler here. Good time to replace the seals, repack the bearings, inspect those bearings, or just order a new kit to fit right on here and then you'll know you're going to be safe as you go down the road. All right, now we'll lower it down until the tires touch the ground and you'll want to be sure to use a torque wrench and get all of your lugs torqued down appropriately. That's going to complete our look at the line of the Timbren Axle-less Trailer Suspension Systems.

Only been driving around on the axle-less system for about a week now and it has far exceeded expectations. I get better gas mileage, my trailer now sits like it was intended to, my trailer doesn't bounce like it used to, I wouldn't trade this axle system for any other. Just wish I would have known which outboard assembly arm my trailer needed with the axle-less system before I placed my order. Still not a problem though, plan on using the wrong outboard arm to build a different trailer. So far, a great product! 208571

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
I was amazed at the attention given to me and my order. I was kept up to date untill my order arrived, it also arrived a few days before the expected time. The axle less system looks to be so much easier to install and more functional than the regular spring suspension. If compared by cost and labor to the other spring system, I find that this is considerably less. I have yet to install it, but will send photo of finished product as soon as possible. 178367

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
A little bit pricey, at first. But in the long run they are cheaper. We used to bend or break an axle every 3 or 4 months. But we have had these a couple of years now with no problems. One thing that is nice is on a tandem axle set up you can get a flat and you just have to take the wheel off and run on 3 or 2 wheels without the hubs hitting the ground. 593458

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
Timbren Axle-Less Suspension - Spindle Only - Regular Tires - 5200 lbs Item # ASR5200S01 Looks great on empty trailer, idea is good, bad execution. When loaded tires "splay out" severely, excessive tire wear, obviously too much play in system somewhere. 584361
Comments
Excessive camber which causes wear on the portion of the tire tread closest to the trailer can be caused by a few different things. 1 The axle-less suspension system has a 5200 lb per set capacity, so youll want to be sure this amount is not being exceeded. 2 The surface of the trailer that the suspension member is added to needs to be an integral part of the trailer that should have NO give in it whatsoever. Any flexing of the side member there will throw off the camber of the tires. I have seen what you describe occur when the suspension system has been mounted to tubular steel that made up the edge of the trailer frame. In that instance, some angle iron was added to stiffen things up. 3 Its not required, but a piece of 2x3 inch tube steel of the appropriate length can be used as a beam connecting the two sides, utilizing the existing hole in the axle-less suspension member. This will help stiffen things up. 4 The suspension system should have included some shims that can be used where the spindle attaches to the suspension portion of the assembly. Using these shims can decrease the camber, but only if the points mentioned above are taken care of. Ive checked with Timbren regarding the above, and they concur.

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
This is my favorite suspension system in all the world! Rides like an absolute dream. Easy to set up and install. Works on any trailer frame size. One thing to know: You don't get the ride height you get with a standard leaf spring suspension. Even with 15-inch wheels, the ride height is pretty low - maybe 10-12 inches of ground clearance to the bottom of the main trailer frame. If you need more ride height, get the lifted version. A few areas of possible improvement? It's difficult to bolt the suspension unit to a crossmember using the middle bolted hole, which uses a tacked-on weld nut. You have zero room for error when drilling the hole through your cross member, and you can't really use the suspension as a template. Hmmm ... also, the hanger plate mounting holes are positioned 1-inch from the bottom of the trailer frame. That makes it very difficult, since I use channel side rails, to use standard 1/2-inch USS or SAE washers on the backside. There isn't room. Just an extra 1/4 of a inch would allow me to use standard washers underneath the nuts on a channel frame. Nitpicking aside, it's amazing. 410020

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
Purchased 2 sets of the Timbren 1200 Axle-less systems for upgrading the suspension on an older 30' ft glider trailer. Single axle with small (13") tires made towing tough due to porpoising, dragging on drive entrances do to poor flotation; also German made and metric, no repair parts. GVW 2000 lbs equated to bouncy ride. Dual sets now allow the trailer to ride over bumps and sharp inclines easily, smoothly, little bounce on country roads; porpoising is history. My glider now rides securely, safely, quietly. Install time 4 1/2 hours (includes head-scratching). Results are outstanding, units are totally solid. Recommend the square tube interconnect, easy and quick - trailer frame was on the light side, so a precautionary fix. Clean look underneath. Ordered 5 wheels w/tires, very nice. Helpful neighbor so impressed he ordered a HD single set for his new DIY snowmobile trailer. Customer satisfaction 100%, from phone order, online support, product information, immediate shipping, install instructions, followup... HIGHLY RECOMMENDED! 580744

I have just a little more to add regarding my purchase: Two sets, of the Timbren Axle-less assemblies, 1200 lb, and 5 wheels. I placed the order via phone, and whoever was on-call that day provided great answers and recommendations regarding the units, wheels and tires. At 31 feet, the trailer originally exhibited amplified porpoising on any bumps or dips in the road. Also bouncing and occasional sideways tipping due to the single axle. It made a lot of noise on my mountain community washboards. I speculated that the Timbren units would solve most, if not all of these problems and they have. Installation on my older 31 ft European ie, metric and no longer manufactured glider trailer was a mere 4.5 hours from removal of the old single axle to setting the trailer back down on its new assemblies. Instructions are complete, precise, useful and helpful. Appreciated. Little to comment on as installation was all straight-forward. I would like to describe the maiden voyage to the airport and back, but there is nothing to tell, other than it towed beautifully proper alignment instructions, and all that I viewed from the rear view mirror looked like a magic carpet ride. It rides over washboards and pot holes like a marathon hurdler, the 4-wheel independent suspension is great. Packaging: the shipping boxes all arrived in good condition, but the cardboard component boxes inside them... not so much. Most were ripped and open due to heavy components lightly surrounded with brown packing paper, just token amounts. Parts: all was accounted for minus a pair of spindle axle washers for one set, easily replaced at the local farm and ranch supply. No squawk, just an fyi. I am very pleased with your product and support, and was happy to leave a 5-star review with photos. The upgraded suspension was also a topic this past weekend at the glider port by those who regularly trailer their ships to various soaring events, some as far as a thousand miles away. My compliments to eTrailers, hope you can use my info,

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
It looks like a wonderful, well built system. The shipment was partial, turns out they forgot the rest. Customer service corrected the matter, still took almost 2 additional weeks to get the rest. The packaging for shipping - The suspension pieces should be packed individually not together. The box was torn in half and falling out, scratched up like it had fallen out of the box during shipping when it arrived. There were no installation / alignment shims or mounting hardware in the box, don't know if they were included and missing or they forgot that as well. I found no information on the paperwork for the inventory expected to be in the box. 424016

Excellent, helpful customer service sold me this product, and trust me when I say it's worth the price tag. Pulled the old axle and leaf spring off a 60's era Bantam and swapped out for this with a support bar in between. Bumped up tires to 315/75r16 BFG TA/KO's to match my rig and am amazed at how much better this trailer now pulls. Empty it wad bouncing all over the place with the old axle and leaf spring setup. Now I hardly even know it's there. Was very easy to install, took a couple hours but I am happy with how it turned out. A+++ product and customer service! 172019

They are GREAT! I put them on a small offroad trailer that has followed me all over some really rough roads in remote Oregon, Washington, and Idaho. They have performed flawlessly, helped the trailer tow extremely well, and were the single best upgrade I did to that trailer. Very much looking forward to another summer of exploring! Massive upgrade to the stock axle leaf spring combo, and I have had the opportunity to show it off to alot of fellow overlanders. I cant speak high enough of them. I also purchased a set of airbags for my vehicle which unfortunately have not held up terribly well. I have had to field repair one once already, and neither holds air terribly well. Truth be told they seem very underdesigned for the job they perform. From my super secret high tech pocket internet window.

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
I think their axle-less design is very clever. The build quality of the suspension part looks good. I have heartburn over the spindle build quality. The spindle is mounted to the suspension and then the trailer wheel mounts on the spindle. The spindles I received are warped from welding. The plate that bolts onto the suspension does not mount flat due to this warping. I called Timbren. The gentleman that helped me was very pleasant. I described the problems and he said he would check his inventory and call me back. He did call me back and said they are all like that. He said get out the grinder and fix what you can and just tighten the bolts super tight, maybe the gap will go away. Really? Wow. The other problems are a LOT of weld spatter where the bolts are supposed to fit and they made a bend in the plate too close to the bolt holes so two bolt heads hit the bend and dont fit flat against the part they are supposed to hold together. Yikes! I am taking the spindles to a machine shop to fix them but I would not have ordered this Timbren stuff had I been warned before hand. So, fair warning. 100490

Your comments regarding the Axle-Less Suspension are greatly appreciated. To address the issues you have pointed out, we have carefully reviewed our assembly. While we did not come across any major issues, we did however discover a few areas where the quality could be improved, specifically in the areas you brought to our attention. The following improvements have been made to improve the manufacturing process: - Robotic welder gun re-programmed so that it stops from getting too close to the areas adjacent to the mounting holes of the outboard arm and control arm. This will minimize weld spatter. - The distortion of the flat plates is due to the high degree of heat generated during welding. We conducted experiments, changing the sequence of welding operations until we were successful in minimizing the distortion. We apologize if our customer service in addressing your concerns was insufficient at the time of your phone call. Timbren is an ISO 9001:2008 company with an excellent reputation for providing customers with quality products that are well-performing and easy to install.

I installed these on a small jeep style camping trailer that I built. I plated my frame and also used the suggested two inch square tubing to tie them together. It rides very well, looks like it should be very durable, it's a simple design, simple to install, more economical than other independent systems, has less parts to go bad than other systems, I would highly recommend to any body using a trailer on rough roads! 582196

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
Used this on a camping trailer behind our Jeep. The suspension handled 1000 miles of washboard gravel roads and mild rocky offroading with ease. We don't drive gently and had the trailer airborne at one point. The brackets that we opted to fabricate for them were straightforward and simple to install. I especially like the ground clearance under the trailer that you gain due to the lack of a solid traditional axle. The ride quality overall was excellent, especially given where we took it. In hindsight we should have gotten the 4" travel version as it may have been able to soak up deep ruts at 40mph a bit better. Only mild complaint is that the powdercoating on the leading edges had already begun to flake off when we received the suspension. I hit it with a can of spray paint, but I would have hoped it would be more durable. Overall, I will definitely be purchasing this axle-less suspension again for my next trailer build. 230177

Ashley, the 4 version doesnt actually give it more travel. Its the same was the standard or the system as far as suspension travel. What the 4 system does it lift the height of the trailer from the ground, depending on what youre doing with the trailer. For an off road trailer I personally would do the 4raise for added ground clearance, just gotta make sure the trailer doesnt get top heavy. The standard system is good for pretty much all uses and the system is for when you need a really low deck height for a lawn mower or go kart for example. I appreciate your review as I am going to be building a small off road campingbug-out trailer to tow behind my lifted FJ cruiser. I havent decided if I am going to go with the standard height or the 4 lift as I am going to be running the same off road tires toyo RT that I have on my FJ on the trailer and I want the trailer to sit around the same height. Did you add brakes to yours? Im planning on either running electric brakes or if available in am going to run surge brakes.

Michael, My trailer was so light even fully loaded that I didnt see the need for brakes and never missed having them.I stand corrected: We did get the 4 lift, but the non-HD instead of the HD because the specs said that it had a bit more travel. and we didnt need the weight capacity. That being said, Im still happy with how this suspension performs. My trailer is on 31s on a stock Cherokee.

Pleased with ETRAILER, will order here again. Not as happy with the torsion axle setup. 2 inch square opening for tying both axles together with your own 2" square tubing are not shaped to match 2x2x1/8 tubing. Grinding and welding of tubing required to make it fit. Also found the overslung stub axle left the end of the pivot arm without much ground clearance though the unit was intended and spec'd for atv tire off road use. A pivot arm with mounting pads top and bottom would be better and allow the user to choose high or low clearance use. I found the units were perfectly suited to offroad use once I fabricated new mounting pads and welded them to the bottom of the arms. 263841

After a year of off road use, I couldnt be happier. My trailer rides smooth loaded or unloaded. No of that bunny hopp with leaf springs or rigid mount axles. The small rebound control snubber works perfectly! I modified my components for high clearance but the concept is sound, they work well. Great job Timbren!

This suspension system did EXACTLY what I wanted. I replaced the leaf springs, axle/hubs on my small trailer. The new suspension improved the capacity, lowered the bed 4+inches, improved ground clearance and allowed me to rebalance the trailer all WITHOUT having to have any welding done. Everything needs to be measured very exactly and the alignment technique is fairly cumbersome and takes a bit of time. In the end, I have a quiet, steady, strong, low riding trailer.

These units install easily, are well made, and perform great! The trailer doesn't bounce around like you see a lot of trailers do while traveling down a bumpy road. I traveled some unpaved roads with no issues. I am certainly glad I went axleless. I installed with 15" tires. Problem is I didn't go big enough. I intended to install on an existing trailer that I had. Changed my mind and built a new trailer. The new trailer came in heavier than I had planned. 2k pound capacity is now too small. I have to watch what I load the trailer with so I don't over load the suspension. I intend on buying the 3500 pound units when I have the money. 289894

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
The product got here in great time delivered on time as said. But I had problems with the square hole in two of the suspension brackets -- the had one side of the inside tube that had a large radius that won't fit the square tubing you are going to slide through it. I spent a lot of time trimming the bracket and rounding off the tubing I need to install. I live in a residential neighbor hood and working early in the morning. Fitting the tubing in the hole it gets wedged in and I had to pound it in to get the fit needed. Too noisy and it should fit to start with. If a person knows he is going to use this square hole in assembly then the seller needs to send the brackets that fit properly. I have to build a sub frame for this small trailer because the shelving tubing I am using for the deck is too light of gauge to put the suspension system directly too. And I had to chase the threads on one of the spindles because I couldn't turn the nut with channel locks to adjust the bearing to fit. Hope the rest of the assembly goes easier. Still got lots work to do but too hot in after noon. 209085

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
etrailer does not provide sufficient information for a customer to correctly choose wheels / tires for this item, so while the suspension looks great and I'm looking forward to using it, I ended up with the wrong wheels/tires: specifically, this will NOT work with 14" zero offset rims (which is almost all of them). I got an RA on the wheels which guess what I can't use it because the only reason I know they don't work is I mounted them so I've wasted DAYS of my time with no progress on my trailer and STILL do not have a confirmed answer that if I buy X rim it will work with these despite writing to the person who helped me place the order days ago and no answer. This is really not what I expected I'm pretty wildly unhappy at being ignored. 524906

Great product.. My company manufactures trailers with our own axle-less suspension, however we have abandoned our own design in favor of the Timbren system. It is far superior and more cost effective to use the Timbren. Also, the Timbren can be adjusted for camber, a nice feature on a trailer. Just be sure to order the correct spindle for your application. Exchanging the spindles with etrailer became a nightmare. I eventually kept the original spindles and bought new ones from Timbren directly. 182264

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
I live in California and I'm building a custom off-road camping trailer for overlanding/camping, mainly for the Sierra Nevada backroads, but possibly for longer trips in a variety of terrain. I had read about the axle-less suspension from Timbren and found that it's a popular choice for these types of trailers. In my searches, etrailer.com came up frequently. So I posted a few questions on their web site, and got a prompt response with tons of great information and a complete parts list for what I needed. Much appreciated! The order handling and shipping was very prompt, and all my parts were shipped in one shipment which I definitely appreciate since I don't get packages delivered to my door. I received all the packages today. Great customer support, prompt handling, and quality products. I gave 4/5 stars because the packaging could have been a little better. One of the boxes was a little banged up in the corners, but the content was unharmed as far as I can tell. I've also received follow-up emails to ensure that I received everything and that it was in good shape. Overall, I'd highly recommend the company, and I won't hesitate to buy from etrailer again! My trailer build will probably take a few months to complete with all the bells and whistles, but I'll be sure to post pictures from the process. 546087

Review from a similar Timbren Axle-Less in Trailer Leaf Spring Suspension
I was looking for a low profile axle system for my motorcycle trailer. The primary requirement was to be able to load my motorcycle by myself which required a low-profile trailer. With the 4" drop provided by Timbren, this setup turned out great. I originally intended on using ramps but after I swapped the leaf spring axle out with the Timbren, I found I was able to ride my motorcycle on/off without the need for the ramps. Originally, I was going to go axle-less but I found when torquing down the assembly to my frame it started to compress the aluminum rail. To take the pressure off the frame I added the 2" bar from axle to axle. Pulls smooth and effortlessly. I've had several people comment on the trailer height with one wanting to buy the trailer from me. This person worked at the local Honda Dealership. He thought it was a great design and I would imagine he's seen a variety of trailers come through his lot. The other option I considered was a torsion axle but I was looking for the lowest profile I could get. Therefore, cost was not a key factor. I also like the soft ride the Timbren system provides. Not sure if the torsion design would have been as smooth over bumpy roads. Regardless, I'm pleased with how this project came out. 352952

Its been a year since Ive installed the new axles on my trailer my comments above still hold true. Im very pleased with the ride quality of the system after a year. The trailer tracks true and has hauled many things other than my motorcycle. Even empty it doesnt hop around like the original stock straight axle did. No regrets on the purchase.

- The dimensions - which you can see in the accompanying photo - are accurate for both systems. The # ASR3500S06 has a 4 inch lift spindle but the dimensions of the unit are the same as # A35RS545 which has a straight spindle; it also has idler hubs with a 5 on 4-1/2" bolt pattern. The other difference is that # ASR3500S06 has no hubs and but will work with hub and drum assembly # 84656UC3-EZ or idler hub assembly # 84545UC1-EZ.
I've added links to video reviews of these parts for you...
view full answer... - What Wheel and Brake Sizes Work With Timbren Axle-Less System ASR3500S06
- It is possible the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle - 3,500 lbs # ASR3500S06 will work with your wheels and brakes, but it depends on a couple of factors: the bolt pattern of your wheels and the size of your brake assemblies.
The hub and drum that fit this system is the Dexter Trailer Hub and Drum Assembly # 84656UC3-EZ, and let's talk about brakes first. This is a 10" diameter x 2-1/4" wide drum which means those are the size of brakes it will work with,...
view full answer... - Timbren Axle-Less Suspension Kits with 4-Inches of Lift
- The Timbren axle-less suspension kits are offered in either 4-on-4 or 5-on-4-1/2 bolt patterns; none is available with a 8-on-6-1/2 pattern idler hubs. All such kits are shown on the linked page.
Several of these 3500-lb kits, parts # ASR3500S06, # ASR35HDS05 and # ASR35HDS02, offer the 4-inches of lift you want and come without hubs. You can use an idler hub or a hub/drum that takes the same inner and outer bearings.

- The only real difference between the Timbren Heavy-Duty Axle-Less Trailer Suspension with 4" Lift Spindle - 3,500 # ASR35HDS05 and the standard Timbren # ASR3500S06 is that the Heavy-Duty model features a larger spindle that would accommodate larger hubs and wheels.
I am not sure why Timbren would have suggested the Heavy-Duty model for your application but the standard Timbren # ASR3500S06 features the capacity you need, the lift you are wanting, and would allow you to retain the use...

- I do have options for you but we would not have a direct replacement for your 3,500 Lb Lippert Axle. Instead, we have the Timbren Axle-Less Trailer Suspension System part # ASR3500S05 or part # ASR3500S06 which as the title states is an axle-less style that replaces the leaf springs as well with rubber bumpers that work to support the trailers weight and reduce road shock better than a standard steel leaf spring.
The Timbren Axle-Less Trailer Suspension System is also very easy to install...
view full answer... - Recommended 3,500 Pound Trailer Axle with 80 Inch Spring Center Dimension
- The longest standard trailer axle we currently have available is an 89 inch axle like the Dexter # 35545E-ST-EZ-89 that has a 74 inch spring center measurement. We do not currently have an axle that will match the 80 inch dimension you are needing.
Another option I recommend looking at is axle-less system like the Timbren # ASR3500S06. This axle-less system will fit any frame width and provides a smooth, quiet ride that can eliminate the need for a thru axle. These have a weight capacity...
view full answer... - Recommended 3500-lb Trailer Axle for Use on Trailer Frame Less Than 76-Inches Wide
- We offer beam axles rated for 3500-lbs that are 89-inches long with 74-inch spring centers and also axles like # CE33201GA that are 57-1/2-inches long and rated for 1800-lbs. If you want to avoid having to use an axle that is too long for your trailer width, then we have a great solution for you in the Timbren axle-less suspension kits.
Timbren kits are available with or without electric brakes and hubs and they are also available with drop-, straight or lift spindles that allow you...
view full answer... - 3,500 lb Timbren Axle Less System Recommendation for Trailer with 4 inch Lift
- Yes, we do carry a Timbren Axle Less system that has a 3,500 lb capacity and a 4 inch lift. For that you'd want the part # ASR3500S06. This is a great axle solution for a trailer and it really doesn't have a downside.
You'll get a smoother ride, longer lasting suspension components and better ground clearance.
view full answer... - Timbren Axle Less System and Hub with 5 on 5 inch Bolt Pattern Recommendation
- First thing you will need to know to determine the correct Timbren system will be the total axle capacity you would need for your trailer. We have ones that range from 1,200 lbs up to 7,000 lbs.
We don't have a ton of hubs with a 5 on 5 inch bolt pattern, but if you went with a 3,500 lb Timbren system like part # ASR3500S06 you could use the part # 84556UC3 for a hub/drum or part # 84550BX for just a hub.
The # ASR3500S06 has a 4 inch lift built into it so it would be great for an...
view full answer... - Recommended Replacement Axle for 2002 Coleman Westlake Pop-Up Camper with Lifted Ground Clearance
- We do not have the thru-axles with the flipped leaf spring mounts already attached. My recommendation is to use the Dexter Trailer Axle w/ Electric Brakes - EZ-Lube - 5 on 4-1/2 Bolt Pattern - 89" - 3,500 lbs # 35545E-ST-EZ-89 if your spring centers are 74 inches and then use the Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00.
If you have different spring dimensions then I instead recommend the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle - Regular...

- The Timbren Axle-Less Trailer Suspension Systems rated at 3,500 lbs, like part # ASR3500S06, are available with straight spindles, 4 inch lift spindles, or 4 inch drop spindles. These axle's are equipped with 4 bolt electric brake flanges.
The Timbren Axle-Less System rated a 7,000 lbs are only available with straight spindles, part # TASR7KS01 or 4 inch drop spindles part # TASR7KS02. The 7,000 lbs axle system does not have a lift spindle option.

- To upgrade your axles to 3,500 lbs I recommend the Timbren Axle-Less Suspension System # ASR3500S06. This system has a 4 inch lift that will help to give you ground clearance when you go offroad.
The etrailer.com Trailer Hub and Drum Assembly, part # AKHD-550-35-EZ-K, is compatible with this axle-less system and will give you that 5 on 5 bolt pattern that you were asking about.

view full answer... - Electric Brakes with Parking Brake Option For Timbren Axle-Less Suspensions
- The Timbren Axle-Less Suspension, # ASR35HDS02, are designed to be used with 12 inch brakes.
Timbren does offer an axle set # ASR3500S06 that will allow you to install 10 inch electric brakes. These axles are rated a 3,500 lbs, but do not have the heavy duty design like # ASR35HDS02 and the 10 inch brakes do not have a parking brake included. Parking brakes are available on 12 inch brakes rated for 6,000 lbs axles.
For 10 inch brake assemblies I recommend the Electric Trailer Brake...
view full answer... - Hubs for Timbren Axle-Less System for 3,500 Pound Axles # ASR35HDS02
- Timbren Axle-Less suspension # ASR35HDS02 takes hubs with a 6 on 5-1/2 bolt pattern only. It requires inner bearing 25580 and outer bearing 15123 and the only hubs that use these bearings have a 6 on 5-1/2 bolt pattern or a very uncommon 5 spoke utility mounting pattern.
If you do not already have the above system then what I recommend is Timbren system # ASR3500S06. It does say that it is for regular tires but there is still 6 inches of clearance from the hub face (center of wheel)...

- I do have an option for you but we do not offer a trailer hub with 5 on 5" bolt pattern that will fit the Timbren Heavy-Duty Axle-Less Trailer Suspension part # ASR35HDS02 or part # TASR5200S03. Instead, you will want to use the Timbren Axle-Less Trailer Suspension System part # ASR3500S06 with the Trailer Idler Hub Assembly part # AKIHUB-550-35-EZ-K as this will allow for the 4" lift with 5 on 5" bolt pattern.

view full answer... - Solution to Promote Clearance for Towing a Trailer Off-Road
- I have never head of anything like that but I guess it isn't out of the realm of possibilities. You'd just have to make sure that your trailer frame is lifted high enough that these tires don't touch the ground if that's what you're going for. A potential issue I see is that this would be heavy enough that they may act as a counter-weight to your trailer tongue and cause the tongue weight to not be heavy enough which can result in poor trailer handling.

view full answer... - 4 inch Lift 3,500 lb Timbren Axleless System Recommendation
- If you are looking to retain your 4 inch lift on your trailer and need to remove the blocks to install a Timbren Axle-Less system you would instead want the part # ASR3500S06 as it has a 4 inch lift built into the kit.
Since this kit does not have brake hubs like the one you referenced you would also need the part # 84656UC3-EZ.
We haven't had any customers inform us that they used this kit on your specific trailer model, but it should work well for you.

- Thank you for your photo and for clearly explaining your concern with your trailer's low ground clearance. You are correct that none of the Torlfex lift kits like # K71-707-01 will work for you since you have the 3-inch high-profile brackets.
In your case the best way to give your travel trailer additional ground clearance is to replace the Torflex axle with a Timbren axle-less rubber suspension that has lift spindles. Kit # ASR3500S06 is rated for 3500-lbs, the same as your # 10 axle,...
