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

Many trailers will have shocks mounted at around a 40-degree angle, but this positioning doesn't compensate very well for the up-and-down movement of the trailer's suspension. Roadmaster's patented adjustable frame brackets are specifically designed to allow these shocks to be mounted at an optimum angle between 20 and 40 degrees. As a result, these shocks will have the leverage necessary to limit up-and-down and lateral movement 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.

We installed these on our 2022 Riverstone Legacy 39RKFB and without a doubt they have saved us on broken rims (many have this issue) and the ride was an instant upgrade. We drove a 6500-mile trip over the summer to ZION and Rockies and no issues at all. I installed them myself and recommend them as an inexpensive solution to expensive independent suspension.



by:

Product came with good instructions and installed exactly as advertised. Haven’t tested it on the road yet. I am going on a trip from Texas to New Mexico. The roads are terrible. Hope this makes the trip easier.

Thank you for the extra fast service service. Its always a pleasure to do business with you

Install wasn’t bad. Grand design welds a V bracket inside the spring hangers for more strength so that was my only challenge on install. This caused a problem on the center hanger as the spacer wouldn’t fit. Had to grind about a quarter inch off the spacer so it would fit as I could only bend the bottom of the hangers so much. Will be towing about 100 miles this weekend so it will be nice to hopefully not have broken drawers in the back of the trailer as well as shelves in the fridge door dislodged. I also did the X factor cross braces on the front and rear hangers for more strength. Will post back after we get more miles on it, but given all the other positive reviews I don’t think I’ll be unhappy.

Installed a year ago, I made a drilling template to help locate the frame mounting bracket screw holes. Installed a set on (2) fivers, spent average of 2.5 hours for total installation per fiver. Helped the ride of the trailer. Would certainly recommend the shock kit.

1. The impression from "people"
was usually "why shocks on a camper", which I would answer "why shocks on your car".
2. The ride was much better; as you may imagine driving your car without shocks. And the sway was minimized & the braking effectiveness increase.
3. We've sold that RV and on our new one already planning the install; and including the wet bolts and mod on the leaf-spring hangers.



by:

This is a great kit! Everything needed is included. Be sure to purchase the heavy duty wet bolt kit for the shackles.



by:

The suspension system is amazing! It feels like the 5th wheel is riding on coil springs. The shock absorbers make such a noticeable difference; why these aren't installed at the factory will forever puzzle me.
Installation was straight forward. The length and quality of current U-bolts allowed for reuse.
I was skeptical about the fasteners, until the first one was torqued to specs...it was soon apparent that the provided hardware was more than adequate for the job.
I wouldn't hesitate to purchase this system again, and I promote it as often as possible.
Thank you, and all the etrailer staff!

OMG! After having the trailer bottom out on the stock springs while traversing a RR crossing, this system has proven to be amazing. Returning from a VA campground I crossed multiple RR crossings and traveled some rough pavement. I found I had left a bottle of shower soap on the ledge in the shower! It was still there when I set up in my yard. Not possible with the stock suspension!



by:

After much research and evaluation I found the Road Master to be my first choice for our 2023 Grand Design Reflection Tandom Axle RV. The engineering, manufacturing and quality is demonstrated in this product. The components are heavy duty with clear instructions. I’ve not had the opportunity to install yet however before we embark on a 2 month tour, I’m confident in this added suspension package to assure a safe, comfortable ride.



by:

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.



by:

Best upgrade you can do on your toy hauler! It’s a little stiff at first unloaded but man what a difference when fully loaded! Smithed out the ride tremendously even on the washboard highway! A huge piece of mind when comparing it to the stock set up. Definitely recommend it!



by:

I spent considerable time researching how to improve the towing experience of my 5th wheel camper without breaking the bank. This is an excellent product and it performed exactly as I had hoped. It improved my trailer's handling over the very rough roads we travel in just about every state in our country. If you are looking to improve your towing experience, then this is a reasonably priced product.

I was looking for shock absorbers when I discovered this kit. I installed it in about a day and a half. The instructions are pretty good if you read them and follow them. We took the trailer about 100 miles last weekend. It seemed to ride smoother with this kit. Overall, I'm happy with it.



by:

So far so good on my 2015 Open Range 3X427BHS!

Overall, the old suspension system was just rusted and worn out and the tires were a maximum of 1" apart, which made me really nervous while pulling. It was tough to remove, but nothing a little WD-40 and some praying couldn't fix!

Installation was pretty straight forward using the included directions and [online video] University. Looking forward to seeing how it rides this weekend on our next trip.



by:

Great kit, really beefy high quality components, nice powder coating. Because my axles are above the leaf springs which I believe is relatively rare, the kit needed some modification, not too bad if you're handy and have additional tools. This kit is a no brainer for axles underneath leaf springs, pretty much bolt on from seeing the eTrailer videos, dramatically improved ride quality on my 20 mile test drive, looking forward to our next trip.



by:

It works well, it was easy to install but the screws that go to the frame loosen with the vibration of the road even using Loctide 271 red, I had to stop on the road to tighten them every 2 hours. As soon as I returned home, I welded them and the problem was solved. The next problem was that the assembly was very close to the ground. I had to raise it about 2 inches more for safety. In conclusion, I give it 4 stars because the comfort is excellent and the price is a little high. taking into account all the extra work it took me until I got a proper balance.

My brother in law installed the slipper spring kit to replace a broken spring and equiflex on the left side of my 2018 solitude 384GK. We found it very easy to install and the written instructions and a couple of videos helped. We travelled from Phillipi WV to Arley Ala. after. I saw a very big difference in the handling and stability of the RV. Was very pleased with the results. I have not installed the shocks yet will do that when I get to Fla.
I purchased the kit from E trailer the service was excellent received everything 2 days earlier than expected, no damage or missing parts. I dealt with Ashley at E trailer she was extremally helpful and knowledgeable.
