Ride on rubber springs with Timbren's Silent Ride suspension system. This suspension system consists of 2 rugged steel units that work with your trailer's existing axles and hubs to absorb road shock, minimize trailer bounce and rattle - regardless of load size - and help to protect your trailer's components and cargo. The Silent Ride system provides a stable ride by distributing the weight of your trailer evenly. The walking beam allows weight to be transferred between axles, ensuring a smooth ride even on unlevel ground.

Silent Ride replaces your trailer's existing leaf spring suspension to ensure that your trailer will ride smoothly and comfortably, no matter what road conditions you are faced with on your journey.

Timbren Silent Ride Suspension vs. Leaf Springs

The Timbren Silent Ride suspension system is a definitive upgrade over leaf springs. Although leaf springs deliver a stable ride when supporting a load, a trailer with leaf springs will often 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.

With Timbren's Silent Ride suspension, you'll enjoy a smooth ride whether you're towing an empty trailer or a hefty load. The Aeon progressive-rate rubber springs of the Silent Ride always deliver the same reliable performance, no matter the load size. If your trailer is carrying a light load, or no load, the springs will compress just enough to counteract any bounce. As more weight is added to the trailer, the springs compress and become stiffer, offering more support for heavy loads. And because they rebound in a more controlled fashion than metal leaf springs, the Silent Ride springs do a better job of absorbing road shock to keep your trailer from bouncing and rattling.

Each spring activates only when needed. This reduces body roll and delivers top-notch performance. 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 a trailer with a Silent Ride 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.

The Silent Ride system also provides smoother load distribution between the 2 axles of your tandem-axle trailer. The equalizers on a traditional leaf spring setup transfer the load from one axle to the other as you travel over uneven ground, but the action is often clunky and jarring. The walking beam on the Silent Ride works to make this transition smooth by incorporating just one pivot point at the center of the unit. The suspension arms on either side of the walking beam are designed to freely articulate around this pivot point to avoid harsh movements and annoying rattle.

Timbren Silent Ride Suspension vs. Torsion Axles

The Silent Ride suspension system is a great alternative to torsion axles as well. While both systems allow either side of a trailer's suspension to operate independently, the Silent Ride suspension system also keeps the weight evenly distributed between both of the trailer's axles, even on unlevel terrain. The walking beam component of the Silent Ride functions like the equalizer in a leaf spring system by shifting the load from one axle to another as you drive over bumps or uneven ground. Torsion axles cannot do this, which can result in not only a rough ride, but also a higher risk of damage to your tires, wheels, and suspension components.

The Silent Ride suspension system also offers greater flexibility for off-road use because of its shock-absorbing springs. Not only do the Aeon springs in the Silent Ride units activate progressively to give just the right amount of support and shock absorption, they also respond immediately. Torsion axles have rubber inside the beam that counteracts shock using compressive resistance, but this doesn't happen until the bar inside the axle twists in response to one side of the trailer going over a bump, for example. This built-in resistance can be effective in maintaining a steady ride, but the design doesn't allow the system to absorb shock as well as the Aeon springs in the Silent Ride setup.

In addition, one frequent complaint about torsion axles is that they cannot be repaired in the event that something goes wrong. But the individual components of the Silent Ride suspension system can be repaired or replaced if needed.

Average Customer Rating:  4.7 out of 5 stars   (58 Customer Reviews)

Trailer suspension system replaces your leaf spring suspension to provide a stable ride. Walking beams keep weight distributed evenly between both axles. Pivoting arms help keep your trailer level on rough ground. Rubber springs absorb road shock.


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.


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.



After a year and approximately 8k mi on the suspension, the Timbren Silent Ride seems strong. The silent aspect of this suspension is no longer silent after things have broken in but not nearly as squeaky as the leaf setup. My stock 2-38” axle beams are slightly bent up at the ends so I’m in the process of upgrading those to 3”. I would also like the next step up in springelastomer but can’t justify the price north of $500 for the 4 rubber springs. When loaded I only have about 1-34” up travel currently before axle bottoms out on frame. My only complaint or recommendation would be for future designs to enable more suspension articulation and up travel capabilities.


Solid construction, and simple installa tion.


Arrived as scheduled. They are very heavy duty. I have not installed them as of this post, waiting on the proper bolts to attach to frame.



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!


Easy to install product is working well for my application


Been great so far..fabbed removable axle system with the timbrens


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


Ok, probably overkill and certainly makes for a premium utility trailer. But compared to other trailers, there’s zero rattling and bouncing around. Install went better than expected too. Did have to weld quick to keep the heat down since the rubbers are right on the other side!


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.


they have worked great as i pull my trailer daily . until one the axle u bolts broke for some unknown reason. and you can not purchase them from any parts supply house


My worries about my trailer have been removed. I am very happy with the suspension system and would recommend these suspension systems.


Awesome product, awesome smooth, awesome load handling. So awesome I'm back ordering jounce-spring helpers from Timbren for my truck. Item # TGMR15MR


Perfect replacement for my car carrier axles


A more stable ride Wolf-Pup Forrester RV trailer.


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 have had both leaf suspensions and torsion suspensions on pull behind campers. I decided to try these when I had to replace my torsion axles. The Timbrens are without a doubt the best suspension I have ever used. The trailer rides much smoother as it creates an independent suspension for each wheel. The rubber pad absorption design adds to the smoothness. The camper is also much more stable when towing and I don,t end up with stuff all over the floor of the camper from a rough ride. I am extremely satisfied and highly recommend this suspension system.


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..


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.


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.


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.


Probably the best upgrade I will ever do to our Roof Top Tent trailer. Rides absolutely amazing. I’ll never run leaf springs again.


Placed these on my 24’ center console trailer. There was an immediate improvement in ride quality. I make several long hauls each year and want suspension parts I can count on. I believe this will be my first suspension that is reliable!


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).

  • Which is Smoother for Tandem Axle Trailer Timbren Axle Less or Timbren Silent Ride
    For a tandem setup the Silent Ride Kit part # TSR7000T04 will be much smoother than two Timbren Axle-Less kits. The reason being that the Silent Ride has an equalizer type setup that allows the axles to move together as bumps are approached which allows for a much smoother ride quality as the trailer and axles move over the bump. The Timbren Axle Less setup does not have an equalizer so each axle will bear the full brunt of the bump independently.

    It does indeed point upward. The axles are designed so that they're upward arched in the center so that then the axle is under load, the contact patches of the tire treads will sit flat on the pavement. Without the arch or camber, the axle beam would arch downward, leading to uneven tire wear on the inside edges of the tires tread.
