This Comfort Ride suspension upgrade system greatly improves your towing experience. It serves as an add-on for your leaf spring suspension, and it provides a notably smoother ride, reducing chucking, axle roll-up, and suspension rebound. This means that you'll experience improved handling, even over potholes and uneven pavement. And the contents of your trailer will stay in place during travel.


Gas Shocks Absorb Road Vibration

While traditional leaf springs support your trailer to prevent bottoming out, they don't necessarily provide a comfortable ride. Due to the rigidity of the steel construction, leaf springs do a poor job of absorbing shock and bounce and limiting sway.


Roadmaster Comfort Ride shocks

Adding these shocks to your existing leaf spring suspension offers a better solution. Gas-powered springs inside of the sealed cylinders compress and extend as you drive. The compression and extension of the springs creates enough force to offset the amount of incoming force or vibration that occurs when you tow over rough or uneven terrain. The result is a more comfortable towing experience.


Comfort Ride Shock Absorbers installed

Typically, when shocks are installed on a trailer, they're positioned at a more horizontal angle. But this positioning doesn't compensate very well for the up-and-down movement of the trailer's suspension. However, Roadmaster's patented adjustable frame brackets are specifically designed to allow these shocks to be mounted at a nearly vertical angle. As a result, these shocks will have the leverage necessary to limit up-and-down motion during both compression and rebound.


Rigorous Testing Standards

The Comfort Ride shock absorber system has endured rigorous testing to ensure its durability and longevity. This testing includes computerized Finite Element Analysis, which establishes guidelines to ensure superior product quality and safety. Roadmaster also tested these shock absorbers at the Navistar Proving Grounds, a private test facility that provides real-world handling and safety testing. The result is a safe, long-lasting product that you can trust.


Installation

Installation of the Comfort Ride system is fairly straightforward.


The included tie plates replace your existing U-bolt tie plates. You will need to retain your existing U-bolts and nuts for installation. Once the tie plates are installed, bolt the upper mounting brackets to your trailer's frame with the included hardware. Some drilling is required when mounting the brackets to the frame. Finally, attach the shocks between the tie plates and the frame brackets.

Review from a similar Roadmaster Comfort Ride in Trailer Leaf Spring Suspension


Just finished installing the Roadmaster shock system on my Momentum 398M tri-axle. The kit arrived well packaged and all items were included. The instructions that come with it are pretty straight forward and easy to understand. This would probably be a lot quicker install with some helping hands, but I did it by myself in about 6 hours. The hardest part of the entire setup is all of the overhead drilling, but with a little redneck ingenuity I was able to make that bearable. As far as this kit goes, the ordering process and the outstanding customer service from Angela W, etrailer.com rocks!! This could be the start of a wonderful relationship.. 630834

Review from a similar Roadmaster Comfort Ride in Trailer Leaf Spring Suspension


I installed this shock kit along with the Roadmaster RM-2560 Slipper Spring System in our 2011 Keystone Cougar 245RKS. As the model number implies, this is a rear kitchen unit. I had over 30,000 towing miles on this trailer and the bouncing trailer caused many issues: doors opening, dishes (and other items) getting thrown around inside the cabinets, many loose fasteners, etc. I had always wanted to add shock absorbers, but this new Roadmaster kit prompted me to replace the springs as well as the shocks. Our trailer has 4500 pound axles, so I was somewhat concerned that the shock kit was designed for 5200-7000 pound axles. But the Roadmaster people assured me that the kit would work fine with the 4500 pound axles, and it does! I did a quick calculation that showed that the new springs are about 14% stiffer than the originals. The shocks easily accommodate the slightly stiffer springs. The kit was relatively easy to install, but you will need multiple jacks and floor stands. Care needs to be taken to get the mounting holes for the spring box correctly located and drilled for simple installation, and my experience went fine. The ride height was very minimally affected - the kit has multiple mounting holes that help with this. And, I was able to use the original u-bolts to mount the new springs, although the instructions implied that I might need longer bolts. We have recently returned from a 7000 mile trip and I am very pleased with the Roadmaster kit. The ride improvement was immediately noticed and things do not get bounced around nearly as much as before. The trailer is also noticeably more stable and not affected as much by wind and passing big rigs. It is really great to get rid of the equalizer link that tied the ends of the original leaf springs together in the middle and allows the trailer to have a proper independent suspension. 614184

Review from a similar Roadmaster Comfort Ride in Trailer Leaf Spring Suspension


I installed the RoadMaster shock system on my new 30 foot fifth wheel because the first time we took the new trailer out (before shocks), the trailer bounced so much that the bouncing broke some plates in our rear kitchen cabinets. The product was straight forward to install. The only hard part was all the drilling into the frame to mount the top brackets. Working on my back, under the trailer, and around the springs with hot metal shavings dropping on my face was not pleasant. However, the installation was fairly straight-forward and the product seems to be very sturdy. I have not taken the trailer out to test the system yet but have two trips planned near term. However, based on how well my previous 5th wheel rode with shocks installed, I fully expect this installation to be well worth the money and I believe it should solve my bouncy trailer problem. 560561

Review from a similar Roadmaster Comfort Ride in Trailer Leaf Spring Suspension


Needed a bit longer bolt than was provided on a trailer. These bolts added the extra length I needed and were a perfect fit. Didn’t have to bend them open or closed to get them through the tieplate holes. 603632

I got my parts yesterday and everything was packed properly and all there. The instruction sheet with a complete parts list along with bolts and other parts. It will be a few days before I install the kit but from the instruction sheets and the u-tube video, I think it will be a simple job to accomplish. E-trade seems to have made the kit and system for anyone with simple tools to install. Thank you for your quick shipping. 595032

Ask the Experts about this Roadmaster Trailer Leaf Spring Suspension


  • Will the Bolt-On Shock Kits for Trailers Work With Underslung Axles
  • I do have an option for you but the Lippert Components Bolt-On Shock Kit like part # LC281281 is designed for use on overslung axles (leaf springs over axle) only. Therefore, it should not be used with the underslung (leaf springs under axle) axles that you have. The reason for this is that the shock absorbers would not be long enough and there could be interference with the axle tube. Instead, I recommend using the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers part...

  • Should Pin Box or Suspension be Upgraded to Reduce Jarring and Bouncing While Towing
  • A cushioned pin box, like the Trailair Flex Air 5th Wheel Pin Box # LC328492 for a Lippert 1621 replacement that you referenced, will greatly improve the ride between your 2016 Ram 3500 and your Forest River Chaparral 37FL whereas upgraded suspension parts on your trailer are geared more towards the ride quality of your trailer. If the jarring that you are getting is from the trailer bouncing around then I recommend starting with suspension enhancement. From the info you gave it sounds...
