Specs:
The heavy-duty Timbren Axle-Less system combines Timbren's standard 3,500-lb Axle-Less system components with 2,000-lb AEON rubber springs, giving you a suspension system that is perfect for your small, off-road trailer. It allows you to use parts that would typically only fit a larger trailer on your undersized trailer. Add brakes for improved control. Get greater ground clearance and increased durability by installing bigger tires and wheels. The reverse drop spindles deliver even greater ground clearance and give you the ability to use larger tires than you could with a standard straight spindle. This makes the heavy-duty Axle-Less suspension system ideal for off-road use.
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.
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'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.
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).
The following diagrams show measurements that were taken with electric drum brakes installed on the Timbren Axle-less suspension system.

Suspension units with brake flanges replace your existing axle and operate independently. Fits any frame width.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
Matt N - 02/06/2016Used 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
Havent had them on the road yet but install was pretty easy and they came out of the box more beefy than i was expecting ???? 564422
I love these. 30k miles and still going. Almost 1k offroad and they're still holding up. Fully loaded my overlanding trailer weighs 2k lbs, empty 1360 lbs. They did settle a little, but I just raised my fenders a little. 345454
Fast service, good informational updates, quality products (the axles look awesome!) reasonable pricing and in time delivery! Very satisfied with the service I recieved from etrailer! I would definately purchase again or refer them to others! Thank you 482874
Timbren axle- less suspension is a great product, this is the second one I have installed on an offroad trailer. Easy to install, pulls great, no axle hop, very easy to service. E-trailer shipped very quickly, arrived in 2 days, would recommend the product and e-trailer to anyone. 240877
Timbren has fixed the weld issues that were reported in previous reviews. The parts fit together very well now. Still working on getting it installed but so far so good. 181073
Exellent product, I installed the Timbren axless suspension on my little guy rough rider teardrop trailer, got four inches of lift and no axle hanging down in the way. I can now run 33 inch tires with no problems. The customer reps Karen and Katie were the best service people I have worked with in a long time, very friendly and went above and beyond to help me, great company great people. Shipping was very fast . Thanks again, Mark 179122

John V - 04/14/2020Review 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

Extremely good product. Rides much better than traditional leaf springs. Ordering. A 7,000lb 8 lug set for the big trailer. 593860
Review from a similar 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 Axle-Less in Trailer Leaf Spring Suspension
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

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

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
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

Built very rugged. I am glad this is available because all the 2K axles I found were not wide enough for my application. This setup allowed me to keep expenses down and build the trailer I wanted. 326161

Review from a similar 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 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
Pat A - 03/15/2018Review 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

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
