When your trailer bottoms out on uneven ground, it’s time for more clearance. The Timbren Axle-Less Trailer Suspension uses a built-in 4" lift spindle to raise the deck height and eliminate the low-hanging axle beam. That gives you the extra space you need to clear rocks, ruts, and steep driveways. With the 7-1/2" distance from the spindle center to the bottom of the frame, the trailer tracks higher and avoids scraping plumbing or dragging over obstacles.
Rough roads don’t have to mean rough towing. The heavy-duty AEON hollow rubber jounce springs take the sting out of bumps and jolts, while rebound springs keep the trailer stable and prevent bottoming out. The 1-5/8" suspension travel cushions your load and limits bounce and sway. Whether the trailer is empty or loaded, the independent action of each side keeps things level and smooth.
Trailer sway and tire wear are common with rigid axles, but the built-in camber and toe-in of this system keep your tires running true. Each side operates independently, so what happens on one wheel doesn’t upset the other. The result is a quieter, more controlled ride, even when you’re carving through tight turns or running on washboard roads.
The suspension arms are made from robust, heavy-gauge steel that can handle hard use in off-pavement conditions. A black powder-coat finish resists rust and corrosion from dirt, water, and road salt. This setup bolts directly to your trailer frame and fits any width when supported by a 2" x 2" steel cross tube. It’s a solid, long-lasting upgrade built for real-world abuse.
This pair of suspension units carries a 2,000-lb weight rating and is compatible with 15" or smaller wheels using 33 x 10.5 tires or narrower. The long E-Z Lube spindles make bearing maintenance simple with built-in grease zerks. Each unit includes 4-bolt brake flanges, 1/2" bolt holes, and accepts common bearing sets—Inner L68149/L68111 and Outer L44649/L44610—so you can match it with hubs and brakes that fit your setup.

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.
We are high production company . Said it was in stock, took way too long for a instock product to be sent. 3 weeks, we did not know when it would come so we ordered another and it comes in two days.
I’m very pleased with the products I received and would like to thank Danielle H for taking the time to help me find the right suspension for my personal build. She was very knowledgeable and by far one of the best that I have spoke with throughout the many industries I have contacted to find what I needed. I would advise anyone to give her a call if you’re looking for a great product but most of all someone who will take the time and with an Awesome Personality to help you find what you need. Thanks Ms Danielle H for all your help.
There were no instructions included, but not really necessary. Installation is very straight forward. I have not pulled the trailer since installation, but all components fit very well and I am sure it will be an improvement.
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
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.
They seam to be very high quality but were very slow to arrive 3-4 months
These axles have been awesome! I put them on a teardrop camper I built and they are great. I was able to easily adjust the camber and toe once weight was loaded on. They also have very high ground clearance which is great for overlanding.
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
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 ????
I replaced a failing torsion bar suspension and replaced with a timbren suspension it was a straight forward installation.
Love these axles. Will install in a week or 2. Fast shipping
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.
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.

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.
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!

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.

Can't wait to hear how the install goes, Christopher! What kind of trailer are you going to install them on?
