Rough roads don’t have to mean a rough ride. The Timbren Axle-Less Trailer Suspension uses AEON hollow rubber jounce springs to soak up road shock and support up to 2,000 lbs. The rebound springs control body roll and keep the trailer steady whether it’s loaded or empty. Together they deliver a quieter, smoother tow that keeps cargo from rattling and gear from bouncing around.
Traditional axles hang low and catch on obstacles. This system eliminates the axle beam completely, giving you more clearance while keeping your trailer deck at the same height. The standard-height spindle is built in, so you get extra space underneath without changing how you load or tow. It fits any trailer frame width and works independently on each side for better handling on uneven surfaces.
Keeping things greased and running smooth is simple with the built-in E-Z Lube spindles. Each spindle makes bearing service quick through the integrated grease zerk. The heavy-duty steel construction and black powder coat resist rust and corrosion, standing up to weather and miles of use.
Uneven tire wear shortens tire life and hurts performance. This suspension has camber and toe-in already built in, so your tires track straight and wear evenly. You get steady tracking and less maintenance over time.
Each of the two suspension units bolts directly to your trailer frame using 1/2" bolts (not included). The 4-bolt brake flange makes it simple to add compatible brakes and hubs. With 2-7/16" of suspension travel and a built-in crossbeam support option through a 2" x 2" steel tube (not included), it installs cleanly and keeps the frame square for reliable performance.

These are going on a single axle trailer. They appear to be heavy duty and well made. The shipping was quick.
Best suspension you can get for off-road trailers. We use this suspension on all of our VORSHEER XER trailers.
Five star. shipping was slow. Product was great 14 K 14 plies under 2000 pounds independent suspension. Low fast and sassy. Yep that’s how I build them.
We use Timbren's ASR5200S03 on all of our XOC and XOC-R trailers. These suspension are well built and have always performed well for us.
We use Timbren's ASR3500S06 on all of our XER trailers. We couldn't be happier. It is a well built suspension.
This is as close to a bulletproof suspension as they come. We use this suspension on all of our VORSHEER XOC trailers. They have performed flawlessly as an off-road suspension.
A must have suspension if you're building an off-road trailer!
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)
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.
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.

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
Again a bit slow on sending
These things look sweet! Cant wait to install them. Fast delivery! Great!
Overall quality and function is exceptional but the hidden nut welded on the inside bolt hole was not correctly aligned when it was welded. took considerable time to correct it
This was a major project for me. My Little Guy 5-Wide teardrop trailer had a failing Al-Ko axle system. I didn't want to try to re-create that mess, and so looked into Timbren. Too many choices! However, once I worked my way through the selections, I ended up slightly downgrading the axle from 2200 lb to 2000 lb. I've had no issues, and the ride is far, far superior to the original.
Installation involved cutting away the original axle bracket, bolting the Timbren to the frame, and adding the 2x2 tubing between the 2 axle sides. This made sure it wouldn't rack--I was concerned the original frame was pretty lightweight. I measured many, many times to make sure I had the axle in the right place, and it worked out just fine. Ride is almost identical to the original axle.
I would do this again, but maybe get a bit more lift next time. I have pretty tight clearance from the tire to the fender. They do make a different model with more lift.
This is a very beefy axle system. Great company.
Oh, and I had a little mixup when I placed the original order with etrailer. I was only shipped one of the two required boxes. A few emails back and forth, and they sent me what I needed. Thanks for taking care of me!
This is my second Timbren independent suspension. Definitely the best ride on the road.
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.
