Note: Your existing U-bolts may not be long enough for this install. U-bolts also suffer from wear and tear, so we recommend changing the U-bolts during this installation.
Upgrade your current trailer suspension setup with the Comfort Ride system from Roadmaster. The Comfort Ride provides an improved towing experience for your tandem-axle trailer. Unlike traditional equalizers, the center hanger boxes in this system prevent shock transfer between axles, creating a smoother ride. In order to absorb and dissipate any road-induced shock that occurs, heavy-duty shock absorbers are included.
One end of each of the included leaf springs will attach to a hanger welded onto your trailer. The eye of the front spring will attach to your existing front hanger, and the eye of the rear spring will attach to the rear hanger. The flat slipper end of each spring will slide into the provided center hanger box.
This center hanger box differs from a traditional equalizer, which typically connects the 2 springs on a tandem-axle trailer. In a standard equalizer setup, any vibration or road-induced force gets transferred between the axles until it eventually dissipates. This occurs because standard equalizers are built with pivot points at their center. So each time the front axle hits a bump in the road, the movement of that axle causes the spring to jump. This pivots the equalizer, which transfers movement to the rear spring and, in turn, to the rear axle, creating an ongoing wave of motion.
With the Comfort Ride setup, the center hanger sits flush with your trailer frame, preventing any movement of the box itself. This isolates each spring, thus eliminating any connection between the axles. To ensure that each spring is still able to move along with the axle, preventing an overly stiff ride, the flat end of the spring mounts in the center hanger box between a roller and a safety bolt. Having a roller positioned above the flat end will keep the spring from hopping inside of the box. Any up-and-down motion the spring incurs will be translated into front-to-back motion to create a smoother, quieter, more controlled ride.
The independent axle operation will improve handling and braking performance as well. Axle roll up occurs when the trailer's rear tires are lifted off the ground while braking, resulting in weight and traction being lost on the rear tires. With the Comfort Ride system installed, tire traction increases by as much as 70 percent during braking because there is no axle roll up. The result is a safer, more comfortable towing experience.
Instead of transferring shock between axles, the Comfort Ride setup ensures that each spring freely absorbs and dissipates any road-induced force on its own. In order to do this, heavy-duty shocks are included.
The gas-powered springs inside of the shocks' 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.
You'll experience up to a 50 percent reduction in the force that's transferred to your trailer while traveling on paved roads. You'll also receive up to a 76 percent reduction over cobblestones and a 94 percent reduction over gravel roads. This means improved handling, even over potholes and uneven pavement, and the contents of your trailer will stay in place during travel.
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.
This Comfort Ride 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 eyes of the slipper springs attach to the welded hangers on your trailer's frame using your existing suspension bolts. The center hanger boxes bolt over your existing center hangers and secure in place with the provided hardware. Once the safety bolts and rollers are installed in the center boxes, just slide the slipper ends of the springs in so that they rest between the bolts and the rollers.
To install the shocks, begin by replacing your U-bolt tie plates with the plates included in this kit. 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.

Great product! Excellent installation instructions (for the DIYer inclined to step up!). Excellent support... I ordered the wrong kit (my axle size was different) but customer service worked with me to correct it. I installed the shocks incorrectly but the service team quickly pointed out that I misread the instructions. I have a 12,000 pound, 38' trailer with a lift on the back for my 900 pound motorcycle. I've put around 7500 miles on it including a couple times across the Rockies and absolutely love the handling. Self installation is not for the feint of heart but it saved me around $10k labor not having a dealer install it.
Less bouncing, furniture doesn't move around when traveling on rough roads, better stability.
With all the proper tools, the install was only like 4 hours. I did this outside on a gravel driveway and then took to my local fire department where it was level to install the shocks. The ride difference was noticed immediately.
This Roadmaster Suspension kit does an excellent job of preserving my 5th wheel camper
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.
Prior to installing this kit, the tires would contact the wood floor of the 5th wheel (Cougar 25RES) and were starting to wear a groove. Now that the kit has been installed the rubbing has stopped. I've also noticed the drawers, that had previously self-opened, are now staying shut. Installation was fairly straight forward. I drilled and tapped the holes, for the plates, as the self-tapping screws refused to go in straight. I also put a nut on the outside screws, the others are blocked by the belly pan.
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.
This setup has been very good in reducing bumps and vibrations into the 5th wheel. It is cost effective and it works extremely well on my 2019 GD Reflection337rls. running 14 ply tires. Two weeks before this review I was under the Reflection and saw the bottom of one of the sleeper springs that had pivoted off center. Before I even touched it I went to the other u-bolt springs nuts to check tightness and torques. The other three showed no change from the install a year previous. The spring that had the issue all the u-bolt nuts were loose....so loose that I could move the nut with a wrench and one finger. So if three were good from the install why is one so bad? I put the spring back inline and retorqued the u-bolts according to the dexter axle data. Is my spring center guide pin bad now? Is this a warranty claim to etrailer? Do I need a new u-bolt due to thread stretching? I have not been on the road. since I reset the spring. Do u-bolt nuts commonly work themselves loose? Most often they do not due to the rust and corrosion. These nuts this loose after a year leave me with some install questions.
This was a worth while suspension upgrade in my opinion. It has eliminated the bouncing around after you hit a ruff patch of road. I also installed Roadmaster’s Slipper Springs at the same time, it has made a huge difference.
The shocks fit as advertised. We took our 14 K 5th for 4,000 mile trip across the country and the shocks made a world of difference. On the return trip we were challenged with 40 to 60 mph winds and the trailer was stable and settled. I would recommend these shocks to anyone with a trailer. I don't understand why with price of a new trailer these don't come as factory.
Installed two of theses on a Tracer 23RBS, 28Ft. Had everything needed for complete install, decent quality. Instructions had just enough info for proper install. Gas shocks a plus, anticipating a more stable ride.
Should have installed system sooner. Items stay in cabinets. Most of the trailer bounce is gone. I would strongly recommend everyone getting the suspension system
I had a tech install the shocks on our 2019 Shasta Phoenix 37FE fifth wheel. He did an excellent job and now we experience a better ride and a lot less surprises when we arrive and open our camper door. Railroad crossing, terrible Georgia interstates, and ruff roads are allot smoother now with less bouncing.
Not being able to experience riding in the 5th wheel RV it's difficult to state the ride quality. However, without a gas shock absorber system the spring suspension is allowed, "out of control movement". Frequently I inspect the suspension and I suspect the Roadmaster System is doing what it's designed for. I would recommend this product.
RE: MORryde RV Shackle Kit-2.25" Shackles-The Wet Shackle Kit is an improvement over stock. However, despite frequent maintenance, greasing, the bronze bushings need to be replaced. With that said, it would be prudent to mfg. the bushings using yellow brass for longevity. It would be appreciated if MORryde would provide all new replacement bushings. During maintenance a top quality tenacious waterproof grease is used.
Overall, doing business with e-trailer is outstanding.
What a great product. The difference it made in our ride was outstanding. You almost forget you are towing a 35 ft 5th wheel behind you. We travel from West coast to East coast over all type roads and this product made such a difference. Sorry we didn't have it installed sooner. Definitely made a differance and would highly recommend to all Rv owners.

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.
Game changer! 2023 Alliance 390 MP (big 5th wheel) The ride, handling and "jounce" improvement is night and day different for the better. The stability in severe weather is literally a "life saver", every larger camp trailer should have shocks (dampeners) on it
My axles are attached above the leaf springs. This complicated the installation a bit but was not prohibitive. I have tandem axles and purchased two(2) of these kits for the trailer. Immediately, we noticed that the trailer was more stable when parked without the outriggers deployed. I wish I could get detailed drawing of the shock brackets. Knowing the designed angle where the shock absorbers mount would have been very helpful with the installation.
I am leaving for my first road trip and look forward to the increased stability during towing and not having the trailer contents thrown about during transport.
Very good product. Instructions and video very good as I installed the suspension and shocks myself. Took me about a day.
I have put about 10,000 miles since the install. No problems & nothing coming loose. Helps to take some of the roughness out of the road vs standard equalizers
It's been a year since I put the comfort ride springs and shocks on my Cedar Creek 5th wheel. After over 8k miles it makes a huge difference in override while towing. The interior of the rv also appears less disturbed after rough roads. Well worth the investment
This is a great kit! Everything needed is included. Be sure to purchase the heavy duty wet bolt kit for the shackles.
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..
We've been on the road since February 2024. And this system is been smooth and great. No broken stuff in the trailer and we've hit some bad bumps I would definitely recommend it.
