Features to know about
Smooth Ride on Rough Roads: Progressive Aeon Rubber Springs Absorb Shock
Leaf springs can make a trailer bounce and rattle when the road gets rough or the load is uneven. The Timbren Silent Ride Suspension replaces those metal springs with double Aeon progressive-rate rubber springs that soak up road shock and keep the trailer steady. These rubber springs compress and stiffen as the load increases, staying active at all times to reduce bottoming out and return smoothly to shape. The result is a quiet, stable ride whether you’re empty or fully loaded.
Even Load Distribution Across Both Axles: Walking Beam Keeps Things Level
Uneven terrain can throw a trailer off balance. The Silent Ride system uses walking beams with a single pivot point to distribute weight evenly between both 2-3/8" round axles. The pivoting arms let each side of the suspension move independently so the tires keep their grip on the ground. This equalizing movement keeps the trailer level and steady over dips, driveways, and bumps, minimizing sway and bounce.
Built for Heavy Loads and Long Life: 7,000-lb Capacity and Tough Steel Construction
Rated for 7,000 lbs, this system is made for serious hauling. Each of the two suspension units is built from heavy-duty steel with a rust-resistant powder coat finish. The rubber components are fitted with durable bushings and covered by a 10-year warranty, while the rest of the system carries a 5-year limited warranty. It’s a strong, long-lasting setup that holds up through miles of towing and changing conditions.
Simple, Low-Maintenance Setup: Bolt- or Weld-On Design with No Grease Fittings
The Silent Ride is virtually maintenance-free. There are no grease fittings to service, and the sealed rubber springs handle the shock absorption without regular attention. It can be bolted or welded on with a 2" x 4" hollow steel crossmember (3/16" wall thickness, not included) and Grade-5, 5/8" bolts for secure mounting. Once installed, it stays quiet and reliable without the upkeep that traditional suspension systems need.
Ready for Real-World Conditions: Powder-Coated and Zinc-Protected Hardware
Salt, snow, and grime are hard on metal parts, but this suspension is built to handle it. The steel frame is powder-coated for corrosion resistance, and all hardware is zinc-plated to stand up to harsh environments. That means smooth performance and solid protection mile after mile in all kinds of weather.

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.

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.

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.

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 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 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.

So far all is great! The highways around here are in horrible condition. My trailer has the straight high brush fenders so you can see the tires and axles in the side mirror as you drive. Those tires are jumping like crazy on the rough pavement, but the trailer body is so smooth the cows think theyre riding in a Cadillac!

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..

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.

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).

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.

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.

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

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.

I have not installed them yet, but by the looks of of them I am very pleased and expect my trailer will ride and handle much better. I won't have to worry about which spring is going to break on our next trip. They look very hefty and I'm inpressed with the engineering and how they look. After I get them installed I will give you an update with pictures.

- Best Suspension Enhancement For Grand Design Trailer With 3,500 lb Axles on Rough RoadsThe best option for your Grand Design trailer with 3,500 lb (or 3,000 lb) axles for bumpy roads comes down to how often you are going to be on roads that are really bad. The Timbrens, like you mentioned, are overall the best option - but also the priciest.

- Recommended Axle Installation with Spring Seats Too Wide for Spring LocationsMoving the spring seats that far is not recommended for the reason your friend gave as it doesn't carry the weight evenly. My recommendation for you so you don't need to worry about the springs is to use the Timbren Axle-Less System # A35RS545E. This will replace leaf springs and mount to your frame giving you the support needed. You can use a 2 inch square bar between the assemblies in the integrated holes.

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.

It also uses a rubber spring suspension system which is more progressive than steel and will help reduce bouncing much better.

view full answer... - Which is Smoother for Tandem Axle Trailer Timbren Axle Less or Timbren Silent RideFor 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.

- Will Timbren Silent Ride Hold Up in Salty/Snowy ConditionsWe haven't had any negative feedback for the Timbren Silent Ride # TSR7000T04 when used in snowy/salty situations.

There are no grease fittings on it though and it does not require regular grease maentenance.

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.
