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.

Excellent product! Absolutely TRANSFORMED my towing experience! Installed on a 2017 Open Range 310BHS travel trailer. Approximately #10,500 loaded. Trailer doesnt bounce or jolt over the road. Ride is substantially bettter. System is tough, thick, and seems it will last. Instructions are pretty clear, and all tooling neede is pretty basic. I reccommend a digital inclinometer to be able to set your shock angles precisely. They're cheap on [online]. I reccommend this kit to every single person who has the same bouncing issue. Could not be happier with the purchase!

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. 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.

The Roadmaster Comfort Ride Shock Absorber kit on our Forest River Surveyor travel trailer was a great upgrade on our travels on rural highways and areas with wind. On our trip last fall from the Oregon Coast to Northern Idaho was a good test of this system and made for more relaxed driving! Should be installed at the factory!

- RM-2460

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, 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.

I've installed this on a 5th wheel about 1 year ago and I have to say I've been very pleased with this purchase. While stuff in the trailer still gets out of place, it feels like it has improved the handling of the trailer over rough roads and during windy conditions. I've probably put about 5,000 miles on my trailer after installing this kit and have to say I have no regrets with this purchase.

- RM-2460

Best thing I ever did takes all a bounce Right out of the trailer and saves on all your appliances inside

- RM-2460

Love my RAS suspension. It did exactly what I was hoping for. Now I pull my trailer with NO rear end squat. It was really bad before I got the RAS heavy duty installed now no far fear with new setup.

- RM-2460

What a difference I paired these with the Cree 3000 and I'll tell you no more white knuckles going over on even bridges

- RM-2460

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

Worth the time and expense, the trailer tracks much better, less movement of items inside the trailer.
Steve - 04/08/2022

Still working fine. I would definitely do this modification. Should have been done by the factory.

This product is exactly what I was looking for and thanks to “etrailer” they assisted me in getting the right product for my specific application. Thank you all for your help and great customer service and support over the many years.

- RM-2460

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

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.

An amazing product. Very heavy duty with all the parts and great directions.

- RM-2460

I was able to install them myself over a weekend. Plenty of metal shards in my eyes, and some heavy-duty drilling into the frame, but all in all doable. The directions were perfect. The ride difference is worth the work for sure - a substantial improvement and impressive value for the dollar.

- RM-2460

this really did not seam to make any difference in the ride or towing of my 5th wheel. the product is made well and it has everything needed to install and fairly easy to install. just didn't do what I was thinking it would.

- 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

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!

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.

- RM-2460

Excellent finish and overall durability BUT, the angles need a little tweaking. The top of the shock will contact the upper bracket as installed to the instructions.

- RM-2460

I did a custom installation on tandem axle 10K car trailer. Made a world of difference especially in windy situations. Highly recommend for any trailer application!

- RM-2460

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

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

The system was installed on a 35', 10.5K lbs (GVW), bumper pull travel trailer. It tows fine and the bouncing has improved, but not as much as I had anticipated. Your advertisement indicated the ride was greatly improved but I find things still falling over/bouncing around. I would suggest the system improves the trailer handling as the axle placement, connect point, road condition etc also effect the trailer handling...

- 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 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.
