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.
Installing the Silent Ride Suspension
In order to install the Silent Ride, a steel crossmember (not included) must connect the left-hand and right-hand units. Welding must be done to attach the included Timbren axle seats to your axle - do not weld the U-bolts. If you already have seats welded onto your axle, you will need to grind or cut the welds off to remove those seats and replace them with the Timbren axle seats.

Video Transcript for Review of Timbren Trailer Suspension - Suspension Replacement System - T43FR
Hey everyone, I'm Ellen here at etrailer.com and we're taking a quick look at the Timbren Silent Ride tandem axle for or suspension for your tandem axle trailer. This gives you a really nice quiet and stable ride for your trailer with that tandem axle. It does work with square axles. So basically how the system is gonna work it's going to replace your typical kind of equalizer and leaf spring system. The issue is that can happen a lot of times if you're using that on any kind of trailer or camper. Whenever you hit a pothole or something like that a lot of times they'll bottom out.
There's a lot of rattling and jostling around and bumping around on the road, especially if you've got a camper or you're using this for maybe a car hauler or something with a little bit more delicate cargo or stuff that you just don't wanna be jostled that much. It can end up causing damage. A lot of campers, you'll find all your drawers, all your cabinet doors are open, things are spilled out everywhere and it can just be kind of a mess. These are gonna eliminate a lot of those issues and make for a really nice smooth ride. The way that happens is because it's going to pivot and provide these Aeon springs, rubber springs to make sure that everything is trying to get back to center as much as possible.
So it's a really nice system. Definitely takes out a lot of the road noise that jostling. You shouldn't have to worry about any of your stuff inside your camper being thrown all over the place. Everything should be just where you left it so you don't have to make or clean up the whole area right when you get to your campsite. Again, as far as how this works we'll have one for either side.
So this is going to be basically how it's gonna sit on your trailer. This would be where the bed of that trailer would go, your camper. So this is gonna be the inboard and this would be the outboard sides. So if we look at this one you can kind of get a little bit better idea. This beam goes all the way through and it pivots here.
So this is the walking beam that will transfer the weight from one axle to the other. That makes for a really stable ride and we don't have to worry about one axle taking all the brunt of the force at once. A lot of the times with equalizers they're supposed to do that, but they don't really do it very efficiently or very effectively. This will do a much better job of transferring that weight as you go over a bump and then the next wheel comes behind it. Each of the spots where the axle will sit, which will be like right here and then right here. These arms are independent right here. So this is gonna be another pivot point. So we'll have this walking beam that's going to pivot right here in the center and then this is going to also move so we have a lot of spots where they can move. There's that Aeon spring right here to try to push that back down and then another spring up inside. You unfortunately can't see. That's also trying to fight the forces to get everything sitting back to center. Having that spring in place is gonna make for that really nice quiet ride. That's why they give it the name Silent ride and it really does live up to it. Just providing that cushion between all the pieces helps to eliminate a lot of that rattle or metal on metal contact. So it should make for a big improvement. Now you will have to do some pretty major work to your trailer. Excuse me. It requires some welding and some drilling to get these guys installed so that's something to keep in mind with this. It does also require a beam to go in between these springs so you do have to get some parts to go with this that is listed the instructions on how to do that. You'll need a two by four hollow tube that I think they recommend that it has a 3/16" wall. Again, you do want to check the instructions for that to make sure that you get it right and also something to think about that I've seen from a lot of customers or a few that have put similar systems on their trailer. A lot of times this ends up dropping the ride height a little bit so you might need to think about putting in some kind of spacers or a little bit of a lift to get this where you want it to be especially if that's kind of close already on your rig if you have body bottoming out issues already, something to consider there. So few things as far as the install, it's not just for the everyday Joe, you'll have to have a little bit of mechanical knowledge to put these guys in place, or at least have a buddy who can do the welding for you or somebody that you can go to to get those axles welded on in place. Again, this is designed to work with square axles. It's 7,000 pound capacity, so that should match up again with what you've got there. That beam that I mentioned is gonna go in between these two seats so that's where they want you to put it. Also will require some hardware to attach that beam and also to attach it to the frame of your trailer and that is not included either. I think they recommended having at least grade five bolts, if not higher. So that's kind of the pros and cons of the system. I think it's well worth the effort, definitely worth the money. It's gonna be a much better system since it really doesn't require any kind of maintenance over time. A lot of times with the leaf springs and equalizer systems you end up having, they wear out and you end up having to replace them over time. With these, you really shouldn't have to replace anything unless something really catastrophic happens. But that's pretty much all there is to it for these guys. I think this is gonna be a great addition to your camper, your trailer, wherever you're gonna be putting this to really make a big improvement in how that handles overall. I hope this has been helpful in deciding if this is the right piece for you. That's always our goal here at etrailer.com is to get you the right part the first time. So hope this helped. I'm Ellen here at Etrailer. Thanks for watching..

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.by: Fred 09/07/2022
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!
by: Chad01/10/2024
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.

Been great so far..fabbed removable axle system with the timbrens
by: Matt.T08/27/2019
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.
by: Heath02/03/2024
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
by: Chris 08/21/2022
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.
by: Daniel 09/02/2022
My worries about my trailer have been removed. I am very happy with the suspension system and would recommend these suspension systems.

by: David10/06/2022
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..
by: Ward05/08/2021
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.
by: Nick09/27/2022
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.
by: Carl R03/04/2020
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.
by: Bryan A01/28/2020
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.
by: Catherine10/09/2022
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.
by: Nicholas 10/03/2022
Probably the best upgrade I will ever do to our Roof Top Tent trailer. Rides absolutely amazing. I’ll never run leaf springs again.
by: Arthur08/12/2020
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).
by: Mark 05/14/2020
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.
by: Dorland Shaffer10/16/2019
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.
by: RV DEPOT06/08/2021
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
by: Glen 08/25/2022
It all looks great, but I found other problems with the trailer so have not installed them yet.
by: Jon 07/02/2021
I like the product. But the instructions aren’t the best one part of the instructions tell you to bolt the cross member on then when you look at the picture they tell you to weld it. If you look at your videos they showed a bracket on the front of the hanger that you can bolt it on. To weld it on you have to be careful not to burn the rubber part of the suspension that is right where they want you to weld it.
