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.


Ground Clearance

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

Components

  1. 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.
  2. 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.
  3. The trailing arm and integrated hanger attach the suspension to the side and bottom of the trailer frame.
  4. The control arm carries the spindle and the hub. It pivots on strong, long-lasting urethane bushings that never require lubrication.
  5. The EZ lube spindle is simple to grease. If damaged, it can be removed and replaced, saving you both time and money.
  6. The hub accepts any 5-bolt wheel that has a regular tire.
  7. 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

Leaf Spring Example

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

Torsion Axle Example

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.


Install Option 1

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).


Install Option 2

The second option for installation is to fabricate an inboard extension plate that attaches the trailer's frame to the Axle-Less suspension.


Install Option 3

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.


Measuring Diagram

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).

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.

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

not happy with one lug nut missing threads!!! but I think they also could supply the wedge plate! the horizontal holes never change and the lower vertical should be slots. for the money I shouldn't have to make a plate. 202996

Received my order. Quality is very good. Intend to use on fishing shanty frame. I thought that the wire I ordered was 4-wire round, not flat. That was my preference but I guess I should have inquired prior to ordering. I feel that the quality of the flat wire could be better. All other products are very nice and I am happy. Service was excellent. Thank you 242026

Just received in a very timely manner. Build quality looks good. Haven't installed them yet but looks pretty simple, will repost after install. The only bad thing I have to say so far is that I wished which is personal opinion is that they would use grade 8 bolts instead grade 5. 203984

Review from a similar Timbren Axle-Less in Trailer Axles


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


Comments

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.

Review from a similar Timbren Axle-Less in Trailer Axles


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


Comments

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.

Review from a similar Timbren Axle-Less in Trailer Axles


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 Axles


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

Review from a similar Timbren Axle-Less in Trailer Axles


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

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

This review is limited to eTrailer customer service since I have not yet installed the suspension. The part I ordered was out of stock when my order was placed. An eTrailer representative notified me both by email and by phone informing me of the situation and offering direct shipment from the manufacturer in the event time was an issue. While time was not an issue for me, I was impressed eTrailer took such a proactive approach in dealing with the stock out. Additionally, despite the item being out of stock, i did still receive it in a timely matter (~2 weeks). 235933

I purchased the Timbren suspension components to upgrade the suspension on my vintage trailer. A phone call to etrailer got all my questions answered and the help I needed to get the right Timbren set and the right hubs. Everything was received in short order in good shape, except there was a small glitch - one part of the system wasn't included in my shipment.

Review from a similar Timbren Axle-Less in Trailer Axles


I used this on my sailboat trailer to lower the height on the boat. A traditional drop axle would interfere with the fin keel. I used the box tube to connect the two units together for added strength and protection. The tube is well ahead of the keel and where the drop axle would have been. I'm also thrilled to have the Timbren elastomer shocks which give a super smooth ride and are immune to corrosion of the salt environment. Multi-leaf springs just don't last when immersed in the ocean, no matter how hard you try to flush them. 282130

Review from a similar Timbren Axle-Less in Trailer Axles


Built a custom trailer to haul an ATV on some bad rural roads in Baja. I used the 2" drop axel-less suspension to allow for full size tires and wheels yet keep center of gravity low. Easy to install on exposed frame, but note that a required brace or 2" square steel bar may be needed and sourced on your own. The finish is not very durable and does not survive the normal bumps, wrench scrapes and scratches of installation; plan on some touch up once installed. Pay attention to the spindle clearance and wheel offset. 317250

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

Nice units, I put them on the trailer I am building for the back of the goldwing, they don't make any noise like leaf springs do, and without a axel going from one side to the other it leaves room to mount a spare underneath, and that makes it easy to balance the trail. Very well built and easy to mount. 322081

First off let me say these axles are EXCELLENT mainly because of their very good design. From what i can tell Timbren is a 9/10 manufacturer. Welds are fantastic(im a professional welder) and this thing is HEAVY DUTY THICK STEEL. Only defect was some paint scratched and one of my grease fittings came right out when i was done greaseing the joint.I welded these up to my custom fabricated trailer and they are just amazing. I would urge anyone to get Timbren suspensions over leaf spring/torsion ANY DAY.. 231681

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

Atrocious packaging! Timbren should be ashamed of how they're sending this stuff out - packaged with flimsy paper and nothing else. Not surprisingly, the spindles arrived damaged to the point where replacements are being sent, and the main arms have big sections of powder coating missing from where the rattled around in the box. On the flip side - Etrailer has been awesome to work with and will be sending out replacement parts. I'll update this post after the parts arrive 352784

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

I ended up returning this product. The axles appeared to be very well constructed but adapting them to my little trailer would have been more work then I wanted to do. I was trying to adapt them to a small Harbor Freight Trailer and the frame on those trailers would require some beefing up in order to attach these axles. If I ever build another trailer, I would definitely consider these axles. 159112

  • Is Timbren Axle-Less Suspension System A20RS545 Better for Boat Trailers than Traditional Systems
  • In a marine application, a Timbren axle-less trailer suspension system like part # A20RS545 would likely outlast a traditional suspension system just due to the fact that there are fewer steel components to rust out. On top of that, the steel on the # A20RS545 is powder coated and will hold up longer than standard suspension components. Another benefit would be that you are losing the axle entirely which would give you better ground clearance.

  • Weight Capacity of Timbren Axle-Less Suspension System # A20RS545

  • When you install the Timbren Trailer Axles # A20RS545 you will end up having a distance of 4-7/8 inches from the hub face to the trailer frame. The rim width of the # TTWAS15B45BM is 5 inches. When you add an additional 1 for the lip of the wheel and then divide that by two you end up with 3 inches of backspacing. I went out into our warehouse and grabbed a # TTWAS15B45BM to measure from the mounting surface of the wheel to the furthest point out on the tire and it measured 3-13/16 inches...

  • Weight Capacity of Timbren Axle-Less Trailer Suspension System with Hubs
  • Each unit (this includes right and left side of trailer) of part # A20RS545 is designed to replace one 2,000 lb axle and is rated for 2,000 lbs. So two such units would be rated for 4,000 lbs. Please note that the total weight applied to the axle-less system (trailer weight plus the weight of the load carried in the trailer) cannot exceed 2,000 lbs. Also, your trailer's design will determine its capacity - not just your hubs.

  • Recommended Components For Tandem Axle Upgrade On Loadrite MC 1800 3 Rail Motorcycle Trailer
  • Thank you for your email answering my questions on your axle. I have the information to help you with your tandem axle application. Your current axle is not a standard size, so I recommend replacing your current axle as well. There are two routes to go for this, the more traditional style or the axle-less. For the Timbren Axle-Less Trailer Suspension System with Hubs - 5 on 4-1/2 - Regular Tires - 2,000 lbs, # A20RS545, you simply mount the axles square and the suspension is integrated....

  • Will Timbren Axle-Less Suspension Fit a 1988 Jayco Dove 6 Trailer
  • You have what sounds like a torsion axle. There are many different types of torsion axles. It could be that the axle insides are worn out. That can happen. But it could also be a bent component such as a spindle. All sorts of things can cause tire wear such as a worn torsion axle, bent spindle, overloading, worn bearings or other running gear components. A Timbren axle-less suspension system such as # ASR2000S01 will work great for you. This particular set up uses hubs with L44649 inner...

  • Timbren Axle-Less System Recommendation for a Small Utility Trailer
  • What we offer that would work well for your utility trailer is a Timbren Axle-Less system like the # A20RS545 that comes with hubs that are 5 on 4-1/2 inch. For a wheel and tire combo that would match the trailer tire size you have and the bolt pattern of the Timbren you would want the # AM30060. If you wanted a traditional style axle you would have to contact a local trailer shop that can order you in custom axles as we do not have ones that would fit it. The Timbren would be the...

  • How to Get a Desired Track Width Using a Timbren Axle Less System to Match Tow Vehicles Track Width
  • The distance the hub face will be from the outside of the trailer frame it is installed on is 8 inches with the Timbren Axle Less System part # ASR35HDS02 . If the wheels you plan on using have the same offset as the wheels on your Toyota FJ Cruiser you will want to take the wheel off of one of the axles and then measure the hub face to hub face dimension. With that dimension you will want to subtract 8 inches from it, and that is how wide of a trailer you will need to build. I wouldn't...

  • Replacement Suspension for Small Boat Trailer
  • We do not carry standard automotive type shocks and the Lippert Heavy-Duty Replacement Shock # LC283280 that you referenced is intended for larger travel trailer suspensions. The trailer axles we offer are intended primarily for leaf spring trailer suspension applications, rather than for suspensions with shocks, but we also do offer axle-less suspension units that can bolt right on to a trailer frame, eliminating the need for an actual axle beam. Given the age of the trailer you may...

  • What is the Difference Between Regular and Off Road Trailer Tires for Timbren Axleless Suspension
  • Off road tires tend to have a more aggressive tread pattern and can be wider/taller. Generally speaking most all trailer tires are regular tires. There are some turf tires and off road tires out there that would fall into this category but if you are not sure I would need to know the tire brand and model to determine which axleless suspension system would work best. I have included a couple of dimensional drawings that show the relevant measurements that you can compare with your tires...

  • Can A Trailer Hub Be Upgraded to Different Hub with A Different Bolt Pattern
  • You will need to know what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub or use a dial or digital caliper to get exact measurements of the spindle. The measurements needed are the parts of the spindle where the bearings ride. If you get back to me with that information I will help you pick out the right hub assemblies. Or, you can follow the link I attached that will take you to the page that has all of our replacement...

  • Replacement 72 Inch Long 2,000 Pound Trailer Axle
  • Trailer axle # 20545I-EZ-72-15 could fit in place of an axle with spring seat center spacing of 57-1/8 to 57-3/8 inches. At the very most the spring seats will have to be cut off and new ones, # TRSS175, welded on by a qualified professional welder for a nominal fee. Another option is an axle-less system, # A20RS545, which is rated for 2,000 pounds and comes with idler hubs. The suspension is built in. With this type of system you will not have to worry about replacing worn suspension parts.

  • What Type of Tires to Use on Home-Built Off-Road Trailer
  • The term regular tires when used in the context of Timbren axle-less suspension systems like # A20RS545 distinguishes this kit from one that can be used with off-road trailer wheels/tires, such as kit # ASR1THDS03. Do please note that for a fabricated trailer you will want to use only trailer wheels and special trailer tires. Passenger vehicle wheels and tires are built differently and are not suitable for use on a trailer. Trailer wheels usually have different offset (the distance they...

  • Using Timbren Axle-Less Suspension System to Replace Torsion Axle on 1985 StarCraft Tent Trailer
  • It sounds like your camper uses a torsion axle. The Timbren axle-less suspension system very well might be a great solution for you. In order to determine which particular part number you need, I'll need to know your axle capacity. This information might be found on the axle itself or on the trailer VIN plate. If not, I can figure it out if you'd reply with the reference numbers from your inner and outer wheel bearings. I'd also need to know if your current axle has brakes and what the...
