Rough roads and heavy loads often lead to bounce and rattle, but the Timbren Silent Ride Suspension keeps the ride steady. Its Double Aeon rubber springs compress and become stiffer as weight increases, so you get the right amount of support no matter how much you’re hauling. These springs absorb road shock, reduce sway, and help every tire stay in contact with the ground. The result is a smooth, quiet, and controlled ride whether the trailer is empty or fully loaded.
Traditional leaf springs can transfer weight unevenly between axles, causing a harsh, uneven feel on rough ground. The Silent Ride system uses a single-pivot walking beam to balance the load across both axles. This design equalizes movement through one central point, keeping weight distribution smooth and consistent. The trailer tracks level over bumps, dips, or uneven surfaces, keeping your cargo more stable and protected.
The system’s heavy-duty steel frame is finished with a rust-resistant powder coat for long-term durability. Fitted rubber bushings keep the control arms fully engaged, ensuring the Aeon springs are always active. With no wet bolts or grease fittings to maintain, the setup stays quiet and reliable mile after mile—just check the bolts periodically and keep it clean.
Designed to replace existing leaf springs on tandem-axle trailers with 3" round axles, this system installs with either bolt-on or weld-on methods. It requires a 2"x4" hollow steel crossmember with 3/16" wall thickness (not included) for connection between the left- and right-hand units. Once mounted, it delivers a stable 14,000-lb total capacity with a 33" axle spacing, transforming how your trailer rides and handles.
Metal springs can be stiff when empty or harsh when loaded. The Silent Ride system adapts automatically—each rubber spring activates only when needed, reducing body roll and keeping the trailer level in corners. From smooth highways to uneven ground, the Silent Ride keeps movement controlled and predictable so your trailer feels balanced no matter the terrain.
Ratings & Reviews
Hi, I install two of this part in one enclosed trailer 7x14 and other open trailer 7x14 with 8 lugs on both trailers and nowi drive very safe ,smooth and trusted not have nothing wrong with this part
As far as etrailer, service was quick and delivery was also fast. As for the product itself, I would rate it a 1. Even after speaking to a sales rep at Timbren, the suspension has not performed as was hoped and assured that it would. (Although Timbren has attempted to make things right.)
As stated, this is no reflection on etrailer, and would use the company again if needed.
In my honest opinion this is absolutely the only way to go to upgrade your suspensionI have installed the 10K and the 14 K models there’s less resistance while towing and the trailer tracks much better it is smoother the bumps are almost not noticeable highly recommend it
I love this suspension its quiet and the handling and ride is the best I have ever used on a trailer. Gonna buy another set for my gooseneck trailer. Will never go back to leaf springs!
This is a very nice outfit for a dual axle conversion. The only problem I had is that the axle saddles and u-bolts either got lost or didn't ship out. Gave e-trailer a call and they answered right away and were very friendly and helpful. They sent me the parts that I needed and they arived in 2 days. As far as the suspension goes, they seem to be very well made and I can't wait to put these under my boat. Looks to be very little fabrication to change from single axle to this dual axle walking leg suspension. It will definitely be easier and cheaper than than dual leaf spring suspension, and should be a lot better.
This system is well worth the money. By eliminating the steel on steel contact when my trailer bottoms out on bad city streets, my axles have not been bent in over two years, where before I had a bent axle every six months. No rattles, bangs, or noise loaded or empty. This is on a 14k tandem flat trailer used to haul an 8k forklift (7k dexter drop axles).
Disappointed beyond belief in both Timbren and etrailer. I not only lost a 20plus year customer I also lost a good friend ontop of being out of pocket the entire cost of this silent ride suspension setup and 8 hrs of Labor .I don't even know what to do with the suspension now because its going to cost me $200 plus to ship it back but the original boxes were thrown so doubtfully it will be accepted and lets not forget about the restocking fee per etrailer I will have to pay as well For what ultimately was their mistakes and lack of honesty that caused all off this.. I paid full price plus expedited shipping costs for complete suspension setup that once again(as it seems by other reviews) was missing all the hardware upon arrival..Then it took 3 more weeks to get that totaling 5 weeks when I paid for and was guaranteed by etrailer to have in 1 week..
Fast shipping no issues.
Installation was a bit more intensive than I anticipated. At the end of our first 6000mi trip, I lost a wheel and the weight of our 7500lb toy hauler was on 3 wheels for up to 60 mi without me even knowing. The suspension and remaining upgraded wheel/tire handled the weight, I doubt the stock leaf suspension would have done the job.
I used these to replace the leaf springs and equalizers on a 20’ gooseneck cattle trailer that I rebuilt. The ride is great and the usual rattling and clanging of the trailer going down the gravel road is gone. So far I am very happy with the ease of installation and the performance of the suspension. I guess only time will tell about the durability of the rubber components in the long run.
This system is a 100 times better then the spring system that was on it new. We put about 5000 miles on our 5th wheel per year. It is a 2015 Columbus and we love it but the suspension was the typical junk under most RV’s. Springs that are as wide as the frame so the perch mounts stick out past the frame. Basically they are like what you would buy at [generic retail]. They sheared off at the frame and the axle cocked. Over a short amount of time the tire blew and wiped out the side of the RV. The suspension I bought from etrailer was great and fixed all the problems the original suspension had. It was a bit of a trick to figure out ride height of the new suspension. You have to add spacers under the original frame to achieve original ride height. Sounds hard but it is pretty easy.
I installed this on a 2018 wildcat 383mb 5th wheel which has a GVWR of 14,059# and with a weeks worth of stuff for a family of 3 I have 10,700# on the campers axels per CAT scale so this is a perfect fit for the application. Now the hard part was figuring out what the ride height (bottom of my frame to the center of the axels) would be since Timbren's documents only show the unloaded ride height at 6.125", with the stock leaf springs my ride height was 9.375” so that is a 3.25” difference but that doesn’t account for suspension sag. I called timbren they said the ride height at 14,000# would be 4” so basically the suspension would sag 2.125" so I guessed my ride height at 11,000# would be 5” or 1.125” of sag. Based on those numbers I would need to make up 4.5” of ride height so I put a 4”x4” 0.25”wall square tube between the frame and Timbren suspension. Well the Timbren sagged more then I expected, and my final ride height ended up being 8.25”, a full inch lower than factory. I have a lot of overhang behind the rear axel and would drag on occasion at the stock ride height so this inch lower is going to make it worse. I’m going to make a few trips and see how much more the suspension settles then I might go back and add a 2” spacer to raiser camper.
The install took me 2 8hr days with the first day being removing the stock leaf spring setup and prepping the axels/removing the leaf spring pads. The hardest and most time-consuming part was removing the spring hangers off the frame man they did not want those to come off. The instructions don’t tell you where to set the axel camber/arch so it set it to the same angle as the suspension arm when unloaded, 19deg which when loaded and on level ground turned out to be perfect. The instructions also tell you weld the axle to both sides of the axle seat well you can’t get to the inside axle seat since it’s so close the rubber spring.
Now as for the ride what a major difference I used to dread hitting bridge expansion joints now it’s no problem, the bucking has been drastically reduced. We would always have open doors and draws when got to a location now they all stay closed. Items in cabinets are still where we left them, cereal boxes are still upright.
This suspension was a game changer on my 2001 20' travel trailer. After multiple broken springs over the years, and loosing the rear axle on a bump heading out of town I bit the bullet and installed the Silent ride. What a difference in handling and overall feel, it's solid & quiet. No worries about road conditions, potholes, or gravel. I have had them on the trailer for a year and about 2500 miles. Towing is a little less stressful.
put these on a dump trailer with 8k axles. had to make an adapter to fit the 8k axles 3-1/2 tube. The ride is great compared to springs.it is a little bouncy when fully loaded but still no complaints.
We swapped the air ride on our helicopter trailer for this system and it is WAY better than air ride. No hoses, no compressor, minimal maintenance, and no adjusting for ride smoothness. One note is that dependent on your trailer setup this can be a pretty rigorous install that absolutely must be done correctly to ensure everything is square and tracks correctly.
Great deliver speed! FED EX beat up the boxes - equipment looks OK
It all looks great, but I found other problems with the trailer so have not installed them yet.
big difference. wish went to a higher weight. id put them on all my trailers
Pricey but well worth it no more bent axles and broken springs which means no down time
Great suspension system. Some of my customers require an air ride system, but some of them have accepted this system as they do provide the smoother ride that their tools need. Well worth the price, plus there is no spring hangers to wear out ever. Overall great system thanks.
Seems like a great product and service was excellent. UPS lost one of the three parts and was a week long in delivering it, and then said that it was because it was packaged poorly from etrailer. I used a 4x6 steel rectangular tube spacer to get my trailer back up to the original height. Seemed pretty straight forward, but it would be nice if the system could be designed so the user doesn't have to cut the mounting brackets off the axle and re-attach the Timbren brackets.
Been great so far..fabbed removable axle system with the timbrens
Outstanding product. The only downside is that you guys made me look really bad with my client because y’all delivered me only half of the order first after waiting for 3 weeks and I was supposed to install it on a big project BBQ Pit trailer.
