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 is not included with this model.
  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).

Review from a similar Axle-Less in Trailer Leaf Spring Suspension


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

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

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 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 Axle-Less in Trailer Leaf Spring Suspension


I pull my Sea Doo GTX 300 (that means they are pretty heavy!) PWC's from Wisconsin to Florida twice a year. That said, this last trip to Florida caused me to bend the original straight axle on my trailer. Not fun. I ordered the Timbress Axle -less axles, and after a few hours of work on the trailer, they were installed, square and true. I immediately put the Sea Doos on the trailer to see how the trailer performs with the new axle-less system on it. one word: FANTASTIC!!!! I guarantee if I have to fix this issue again, I will use the exact same product. It is awesome! 736299

Review from a similar Axle-Less in Trailer Leaf Spring Suspension


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 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


Comments
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.

Review from a similar 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 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


Comments
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,

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.

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

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

Axles of a given weight rating will tend to have specific hub-face dimensions and spring center dimensions. You can use an axle longer than the trailer's width but spring centers must match your hangers. This really depends on all the details of your starting 4 x 8 trailer. Often...

  • Timbren Axle Less Recommendation that Allows 6 on 5-1/2 inch Bolt Pattern to Install
    I have a solution for you, but it will require you to go up to the 3,500 lb version of the Timbren. For that you would want the # ASR35HDS02 and then for hubs part # AKIHUB-655-6-K. These hubs have the 6 on 5-1/2 inch bolt pattern you need.

  • Idler Hub Recommendation with 5 on 4-1/2 inch Bolt Pattern for a Timbren Axle Less ASR1THDS02
    Just because the Timbren Axle-Less Trailer Suspension System # ASR1THDS02 has brake mounting flanges does not mean you have to run hub/drums on them. You can install idler hubs on the spindles just fine. For an idler hub that would fit the spindles that has a 5 on 4-1/2 inch bolt pattern you would want the part # 8-248-50. Everything you mentioned to mount the hub on the spindle comes with the spindle. The Timbren would get bolted or welded to the trailer frame. Welding should...

  • Recommended Replacement Boat Trailer Axle and Suspension
    For your system due to the unique width, I recommend the Timbren Axle-Less Trailer Suspension System - 2,200 lbs # ASR1THDS02. This system has the integrated suspension and just needs a 2 inch square tube (not included) to fit into the integrated holes of the assemblies. For galvanized hubs, you can use the 5 bolt # AKIHUB-545-35-G-EZ-K. If you trailer is much larger, then let me know what you have and I can give you the more compatible load capacity. Normally the 60 inch boat...

  • Which Drums and Brake Assemblies for Timbren ASR1THDS02 Axle-Less Suspension
    The Timbren # ASR1THDS02 Axle-Less suspension is compatible with hubs that use an L44649 outer and L68149 inner bearing like the # AKHD-655-35-EZ-K brake drums you mentioned. These drums have a 6 lug on 5-1/2 inch bolt pattern. If you needed a hub/drum with a 5 lug on 4-1/2 inch bolt pattern, you'd use # AKHD-545-35-EZ-K. Either 10 x 2-1/4 inch hub drum is compatible with the # AKEBRK-35-SA self-adjusting brake assemblies.

  • Adding An Axle To An 83 Dilly Single Axle Boat Trailer With Timbren Axle-Less System
    Yes. You can add a second axle with a Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - Off-Road Tires - 2,200 lbs # ASR1THDS02. When adding a second axle, you will want to ensure that they are the same capacity and use the same size wheels, etc. When adding a second axle the pivot point of the trailer changes, so where your current axle sits is where you would split the distance for a tandem axle application or where your center hanger would need to be if you were...

  • What is Needed to Convert Oil Bath Hub to Grease and Also Pick Out Replacement Spindle
    In general you don't have to do anything to your current setup to convert it to grease aside from just remove all of the oil and replace it with grease. The oil seals will work just fine with grease instead so all you need is hub grease like the LMX Red part # L11390 and you'd be set. Since your spindles are shot though I will need to know more info to pick out the correct replacements. Use a digital caliper like the part # PTW80157 to measure the spindle you have where the bearings...

  • Jeep Wheel Compatibility with Timbren Axle-Less Trailer Suspension System
    Jeep wheels have the 5 on 5 inch bolt pattern and we do have hubs that fit the Axle-Less Systems and your Jeep wheels. It is recommended to use trailer wheels with trailer hubs because of the zero offset and tire design, but people have been using Jeep wheels especially for off-road trailers for years so we know they can work. We only have a couple compatibles option for that size hub. You will want the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/Flange - Off-Road...

  • Timbren Axle-Less Suspension System Compatible with Jeep for Matching Trailer
    For the Timbren Axle-Less kit compatible with the bolt pattern of 5 on 5 like a Jeep, you would need the 2,200 lb capacity # ASR1THDS03. The spindles on the Timbren system are a little larger than their thru-axle counterparts, so the 3,500 lbs # ASR3500S06 will only fit larger hubs that won't have the bolt pattern you seek. Using # ASR1THDS03, you can then use the Trailer Idler Hub Assembly for 3,500-lb E-Z Lube Axles - 5 on 5 # AKIHUB-550-35-EZ-K or the Trailer Hub and Drum Assembly...

  • Wheel Recommendation for Timbren Axle-Less Trailer Suspension System # A12WS545
    After doing some research on the 2011 Jeep Wrangler, it appears the bolt pattern of the OEM wheels is 5 on 5 inches. If that is the case, they will not be compatible with the hubs that come with the Timbren Axle-Less Trailer Suspension System, # A12WS545, that you referenced in your question. The hubs and spindles included are designed for 5 on 4-1/2 bolt patterns. If you are unsure of your wheel's bolt pattern, I have included a helpful article that explains how to measure this. I do...

  • Timbren Axleless Suspension System for 265/75R16 Tires.
    The Timbren Axle-Less Trailer Suspension System part # ASR2000S02 states "regular" as opposed to "off road". The off road version part # ASR1THDS02 has more distance between the hub face and the frame of the trailer. These are very popular with the off road camper that have larger 31" x 10.5" or 33" x 12.5" type tires. With your tire size of 265/75R16 that means you have 31.65" x 10.43" tires with that said the Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - Off-Road...

    While we don't have a 2,200 lb trailer axle that matches the dimensions you need we do have a similar solution with the Timbren Axle Less kit part # ASR1THDS02 which would give you an axle setup that would fit and also cover the need for new leaf springs as well. These attach directly to the trailer frame and provide an axle setup that gives you great ground clearance. See attached video. So then for a hub that fits this with the 5 on 4-1/2 inch bolt pattern you need as well the part...

  • Replacement Axle for 2,000 Pound Dexter Axle on a Pop-Up Camper
    We have straight axles that are close to the measurements you have provided, see link, but the spring seats would have to be moved and none of them have brake mounting flanges. I propose a different approach by using a Timbren axle-less system # ASR2KHDS01. This system will provide the "axle" as well as the suspension in one unit plus the suspension part will not wear out nearly as quickly as traditional leaf springs because the rubber won't corrode. They are also set up for electric...

  • Recommended 3500 lb Axle with Idler Hub Assembly And EZ-Lube Spindles
    I think you will be better off simply replacing the axle. I recommend a replacement like the Dexter Trailer Axle w/ Idler Hubs - EZ-Lube - 5 on 4-1/2 Bolt Pattern - 89" Long - 3,500 lbs, # 35545I-EZ-89, since you have no brakes. This will give you the new axle, the new bearings, races, seals, and hubs on EZ-Lube spindles. Will also give you the clear knowledge if there is another issue because the axle will be brand new. The length of your trailer axle you are replacing will dictate...

If you are looking for an axle that length with a 6 on 5-1/2 bolt pattern, then you will need to use the Timbren Axle-Less System # ASR1THDS02. This will allow you the custom length when utilizing a 2 inch square bar (not included) cut to length in the integrated holes of...

  • 2,200 lb Axle Replacement System for Triton Snowmobile Trialer
    We have an option to replace the torsion axle on your 1996 Triton snowmobile trailer, but do not carry any torsion axles. Instead, the best option we have is a Timbren Axle-Less trailer suspension system which are simply bolted or welded so you do not have to worry about finding an axle that meets any specific measurements. They also offer you an improved ride compared to a traditional through-axle because the Timbrens work independently so if there is a bump on one side of the road it...

    You will first need to know what the trailer is rated for. You can run into the problem just as you stated. If you get a heavier system on the trailer and carry much less weight it can bounce when on the trail. I have a solution that will work for you. For ease of installation and capacity I recommend an axle-less system like part # ASR1THDS02. This system bolts onto the frame and eliminates the axle beam as well as leaf springs and the hardware. This system has a 2,200-lb capacity...
