Rough roads and potholes don’t have to rattle your trailer—or your nerves. The Timbren Axle-Less Trailer Suspension uses AEON jounce and rebound rubber springs that soak up road shock and smooth out the bumps. Each side works independently, so when one wheel hits a dip, it doesn’t jolt the other. The result is a quieter, more controlled ride whether the trailer’s loaded or empty.
Dragging an axle across rough ground is a thing of the past. This system eliminates the axle beam entirely, giving you extra ground clearance and better protection for your plumbing and frame. The standard-height spindle keeps your trailer deck the same while gaining clearance underneath, so you can handle curbs and uneven roads without scraping.
Built for serious hauling, this suspension has a 5,200 lb weight capacity and a 5-bolt brake flange for reliable strength and compatibility. Each unit has built-in camber and toe-in to keep your tires tracking straight and wearing evenly. Suspension travel of 2-3/4" helps maintain constant contact with the ground, giving better handling and stability mile after mile.
No need to hunt down a specific axle width—the Axle-Less design fits any trailer frame. Each side bolts directly on, and the built-in E-Z Lube spindles make bearing maintenance quick and clean through the grease zerks. For extra strength, a 2" x 3" steel cross tube or reinforcement bracket can be added through the square holes to tie the frame together and keep it square.
Everything about the Timbren Axle-Less Suspension is made for the long haul. The strong steel construction resists flex under load, and the black powder coat finish stands up to salt, water, and road grime. Backed by a 3-year limited warranty, it’s a solid, low-maintenance suspension system that keeps your trailer steady, smooth, and ready for every trip.

This Axle-Less system requires crossbeam support. If your trailer frame doesn't have a crossmember in place, you can retrofit it with one, or you can add a support by running a piece of 2" × 3" steel tubing through the square holes cut into these units. You could also add a steel reinforcement bracket to the inside of the trailer frame.

A must have suspension if you're building an off-road trailer!
Actual trailer weight 1540#, 210# tongue weight. 1310# suspension load. After 600 miles, both springs collapsed making the suspension rigid. Have received replacement springs from Timbren but haven't had a chance to try them out.
The order came in on time and the customer service at etrailer.com (Ashley) and Sean from Tmbren was outstanding. They both were very helpful in my choosing the right product for my needs. The axle less suspension's performance is absolutely superb. It vastly improves ride quality. I am using it on a teardrop camper that often goes on gravel roads and the raddling sound from the leaf axles was horrible. A couple of points to consider before you settle on the axle less suspension: keep in mind that you will lose some hight of the trailer. While you will gain clearance from the lack of the axle, the suspension will make the trailer sit lower than before.i had to lower my hitch by an inch to maintain the trailer leveled. Also it does appear to compress at higher rate than the leaf springs, which makes it softer but easier to reach it's limit. Overall this product is absolutely a must if you are looking to improve the safety and the quality of your towing.
Timbren saved our RV road trip! The leafs on the axle on our 2018 Jayco TT came apart while driving in Maryland. We tried going to the manufacturer, but they were useless. Going to a RV mechanic meant being grounded for at least 2 months. Then we found Timbren. With the help of Timbren's excellent staff we purchased axle-less system through etrailer, who made sure we got as quick as possible. It came ahead of schedule, my husband installed the Timbren system and we were back on the road! The axle-less system is better than the original manufacturers. If you plan on taking your RV or TT farther than 100 miles GET THIS INSTALLED and get it through etrailer.
Very exicited about these axels, I have been eyeing these for over a year. (Excellent service from etrailer, they had my parts to me in 1 day from the time of placing the order.) These axles seem to be well made and fit nicely with the Dexter hub and drum assembly and the 12" electric brake kit. I installed this all on a M1101/M1102 trailer frame after removing the factory axel assembly. I have not ran these on the road or off as of yet but will give another review at that time. The fit and finish are great and the packaging was good, a little banged up from shipping (missing 1 washer)
Hi Amy,,
I got my order yesterday, it is perfect for what for my off road camper trailer project.
Maybe a little (lot!) Over kill, but where it will be going I don't think over kill is a bad thing.
I have made a lot of purchases from you guys and have never been disappointed.
I will probably need to purchase the hub/break assembly next.
Thanks for everything,
Trailer suspension and disk brake performance is outstanding big big difference over leaf spring and electric drum brakes.
Installation required modifications to the frame to monut the timbren suspension
Customer service is amazing! Thanks to all of the team at etrailer.
The trailer rides great down the road and no more worries about saltwater and rusty leaf springs. Not a cheap option but I’m very happy with the setup. When installing, just be sure to measure accurately and have sharp drill bits. A drill press type of guide also helps ensure correct drilling angles. The first picture is of a mounting gusset a local welding shop made. One is needed for each side and necessary to provide needed mounting strength-at least on my trailer frame. Pics 2 and 3 show the mounted suspension on one side of the trailer. Pic 4 shows the suspension on one side of the trailer with the axle attached and a separately purchased disc brake assembly mounted on it. Finally, pic 5 shows a 2” box channel between both suspension assemblies. Independent suspensions would have been nice, but I wanted to ensure trailer rigidity was maintained. So, after one year, so far, so good. It’s all smooth sailing down the highway.
Installed the Timbren Axle-less suspension a little over a year ago and approximately 5000 miles ago. I have been extremely satisfied with the installation and performance thus far and have had no issues. I also chose to install an optional crossmember for more strength using a 1/4" thick piece of 2x3 steel. I had to increase the weight capacity of my campers suspension due to renovating the interior completely and adding more weight. I also strengthened the frame to accommodate the extra weight. In addition to installing the Timbren 5200LB system I installed new 12" electric brakes and upgraded to 225/75R15 tires with E load range rating.
Best axle system for overland trailers and their travels, great independence system for those 1-6 trail ratings, simple to work on , easy bolt on system. I would recommend to grease after each trip . The standard Duty -4" Drop- 4Bolt Flange- 3500 lbs give me about 21" clearance with 35" x 12.5 tires
Looks very well made
Work perfectly on my one-off trailer bu ild
Item looks good quality an heavy duty,boxes came damaged an open but seems to still have everything in them,I would definitely order this product again for future builds
Used these to replace half torsion axles on drop down ice shack. Hesitant to spend the $$$ but glad I did. Well built, less space and smooth ride. Replaceable spindles a plus.
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.
The products are good quality and durable. Etrailers has good pricing, shipping and an easy transaction. Etrailers provides so many different trailer products, you can't go wrong. Thank you Etrailer.
Purchased these axle - less suspension sets to build a single axle utility trailer. They arrived in excellent condition and appear well made. Installation instructions are clear and well written. Also ordered hubs, coupler hitch, rims, lights, stake pockets and other heavy items. My order arrived complete, very well packaged and timely in eight boxes. The boxes Etrailer used for packing were heavily made and undamaged in shipping. No missing parts because of the superior way they were packed. I will definitely order from Etrailer again.
This isn’t the first set of these I bought I have around 25 trailers with these axles on them we farm for a living and these trailers go in and out the rough field bringing produce to the packng facility best money he’ll ever spend would recommend
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.

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.
