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 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.

Along with the new springs....everything works as advertised. Well satisfied. No complaints. I had to modify the one set of shock brackets to fit, as I have raised the trailer 5 inches to match up with the 4 inch raised truck. Otherwise...no swaying....no bouncing........no problems. Thanks etrailer for your help.

Great. On a 32 ft. WildCat fifth wheel..No problems. In the driveway, I installed the Shock system, heavier springs. I had to modify the shock-to-frame brackets, as the trailer has been raised 5 inches. Along with the MorRyde Stabilizers the trailer tows like a dream. Be sure to have the wet bolt grease nipples pointing out to the side of the unit for easier access. Next project will be to replace the scary Magnetic Brakes with a hydraulic system. Thanks etrailer. Kudos to your wonderful support crew. It was just like calling my buddy next door.

Great buy and easy to install and has made for a smoother ride.

The product is working as advertised. We continue to get a more smoother ride. I would strongly recommend this product to all your customers.

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..

Still feel it is the best upgrade you can do short of going independent. Still a great product for the price.

Every towable RV should be equipped with these shocks at the factory especially those like us that have a rear kitchen! The ride difference before and after is 'shockingly' (pun intended...) better. No more broken dishes and I know all of the installed components in our 2021 Keystone Cougar 29RKS suffer less wear and tear, and damage from road travel. It also made our tow vehicle ride much better than before the shock install due to 'bucking' on the fifth wheel hitch when towing the -29RKS. These shocks have been the best upgrade/add-on we have ever added to our current RV and four others in the past. Do yourself (and your RV...) a favor and INSTALL THESE SHOCKS! You won't be disappointed.

I pull a toy-hauler 5th wheel trailer between Alaska and the lower 48 through Canada twice a year. Much of the road is rough and caused me to break a leaf spring every trip. Since installing a shock absorber system and upgrading from 5-leaf to 6-leaf springs, I have so far eliminated suspension damages on the route.

- RM-2460

Highly recommend adding these on your camper. We added them to our Grand Design 2400 BH which was a night and day difference in ride quality. This eliminated a lot of the porpoising, chucking and side to side roll that you sometimes get. I was amazed how much smoother of a ride pulling the camper is now. Running these shocks now in combination with the Road Armor Equalizers.

Still working great!

This is a great product, it smothered out my fifth wheel nearly eliminating the chucking.

Still working great. It was a great addition to my RV

Trailer trails so much better since we had the road master shocks installed.

- RM-2460

As always etrailer delivered a great product, complete and undamaged in record time. I received the Roadmaster -2460 shock kit for the suspension on my 2019 36 foot fifth wheel three days earlier than expected and completed the installation myself in approx. six hours. Anxious to take it down the road and see how much it has improved the ride in my coach. Great price, easy installation and good instructions for those mechanically inclined DIY's.

The Roadmaster - 2460 shock kit improved the ride in my 36 ft. fifth wheel, eliminating the rough ride and jarring we had been experiencing previously. We have traveled approximately 10,000 miles since the installation and are extremely happy with the performance.

I live in canada, the cost of the shock kit was xxx.xx Canadian cheaper than what I could buy it for in here even with the Dollar exchange and shipping, and I got it 7 weeks sooner than any other dealer I contacted here in Canada. The service from etrailer was excellent and the shock kit arrived on time as promised from UPS. Thank you etrailer for your excellent service, I especially liked the package tracking system. I was able to see the progress of my package from the time it was picked from the shelf to every step of the shipping process. I will purchase more from etrailer in the future now that I've experienced how easy the process is. *** If you are ordering from Canada insure you call etrailer and confirm the cost of Canadian to US exchange and the shipping cost. Remember that all figures are in US dollars.*** I have not yet installed the shock kit but I will update my review once it's installed and I've had a chance to pull the trailer.

I purchased this system for our 2018 Coachman Chaparral. We had noticed that it would sway after crossing bridges and especially when coming out of a curve or while turning. I found this system to be very helpful. I welded the mounting brackets to the frame of the 5th wheel and bolted the rest as instructed. I would recommend this product to anyone that wants to stabilize their RV. Thank you for allowing me to write a review.

- RM-2460

Well, all the shocks are installed. Working on my back is hard, not as easy to do stuff today as it was years ago but I got I done. Sharp drill bits and using the frame mounting plates as a guide was the key. However, I had so much dirt and metal bits in my hair I had to take my dogs flee comb to my head before I could shower. Now for the next project whatever that is. I’m sure I’ll think of something.

- RM-2460

Fit perfect on my ‘21 Vanleigh Beacon Packaged good and all parts were included Stacy shipped promptly

- RM-2460

just finished installing these shocks, the diagrams were true to the end, once you get the past the first one the rest went smooth, just hard working in tight places ( installed them in my driveway), cant wait to try them out on my next camping trip

i wish i had bought these sooner, boy what a difference they made on traveling on washboard gravel roads

Arrived very well boxed, nice heavy brackets, fit well with exception of trying to get angle and length both correct. But after a bit of thinking and grinding and welding every thing worked out quit well. Will find out next week how much improved it will be, as we start our annual long trip estimate about 12,000 miles this trip out.

- RM-2460

Great improvement over stock. Trailer tracks more stable. Less movement of stored away items. Less chucking, pretty much eliminated it.

- RM-2460

This is a great company to work with. They are so helpful and have sent us parts several times.

- RM-2460

Helped my Fifth wheel a lot with the sway while on rough roads! Installation was not bad if you have mechanical ability.

- RM-2460

Had these about a year and they definitely make the ride much more pleasant and snotty!

- RM-2460

Everything arrived in good shape good heavy duty brackets looks great

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.

Arrived early in excellent shape. Looks very well made. Have not installed yet but am sure it will work great. Have ordered from etrailer before and never had a problem. Thanks to Dylan for making ordering very easy. Great service

Working great. Fifth wheel pulls better and things inside don’t get thrown around on rough roads

Fit was great and very easy to install.

Makes trailer ride smith and keeps it from bouncing on over passes.

- RM-2460

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.
