Rough pavement and long hauls can make a rig feel like it’s constantly fighting the road. The Roadmaster Comfort Ride Shock Absorbers for Triple Axle Trailers use heavy-duty, nitrogen-charged gas shocks to calm that motion. Designed for 5,200- to 7,000-lb axles with 3" diameter tubes, each shock limits both compression and rebound to cut down trailer bounce, chucking, and porpoising. The result is steadier handling and a smoother ride over potholes and uneven terrain.
Many standard shocks sit at a 40-degree angle, which doesn’t do much to control vertical trailer movement. The Roadmaster setup uses patented adjustable frame brackets that let you mount the shocks between 20 and 40 degrees for maximum leverage. That near-vertical orientation lets the shocks control up-and-down and side-to-side motion more effectively, improving stability and reducing interior shifting while you tow.
This system has been through Finite Element Analysis and road-tested at the Navistar Proving Grounds to make sure it stands up to real-world use. The triple-axle kit includes six gas shocks that measure 17-1/2" extended and 11-1/2" compressed, giving them the travel needed to handle both light and heavy loads. With a Limited Lifetime Warranty, it’s a long-term upgrade built for durability and safety.
Installing the Comfort Ride system is a hands-on job that’s simple once you get started. The included tie plates with extension pieces replace your existing U-bolt plates and work with 9/16" U-bolts. The upper brackets bolt to the trailer frame with the included hardware, and the shocks attach between those brackets and the tie plate extensions. Once bolted up, your suspension gets an instant performance boost without complicated modifications.
Ratings & Reviews
This is a great product, it smothered out my fifth wheel nearly eliminating the chucking.
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.

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.
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.
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!
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!
Build quality is very good. 4 star rating is due to the hardware for the drop leg was mismatched. Grade 8 sae bolts and metric chineesium nuts.
This is a good kit but no piece of cake to install. You need a nice level slab and your tools close. The workspace is tight and existing suspension bolts are torqued and rusty. I would not attempt this install unless you are fairly mechanical. Parts are of very good quality and engineering and fit are very good. You need a 12” drill bit to install the top bracket. Buy two - there are 16 holes to drill. An electric ratchet is almost a necessity.
Bought this kit to reduce wear on the rv on rough roads. It looks like it should help a lot. I did have sumo springs but had to ditch them. They are not compatible with the new top plate on the spring pack that serves as the bottom mount for the shock.
works well.
Looking forward to first trip and see how much it changes the ride.
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.
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.
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..
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
They arrived when I was supposed to package was very well put together. Instructions were very easy to follow my only suggestion that would be if possible send a 12 inch 5/16 drill bit with would make the job completely easy.
Huge change in how fifth wheel tows. Don’t feel expansion joints in the road when the trailer goes over them and never find anything moved around inside anymore. RV manufacturers should install shocks at the factory.
One year installed and still helping my suspension. These shocks are amazing. Oklahoma roads are tough on RV suspensions and these shocks help suppress the jumping/bucking of the RV. I highly recommend them.
I installed the Roadmaster slipper spring and shock kits on our 2023 Arctic Wolf 3770SUITE and have been very happy with the ride difference and the much reduced "things moving about inside" while towing compared to what we had with the stock set up. Admittedly the kit is pricey and not for the faint hearted if you plan to install it yourself, but it can absolutely be done and has made a major difference in our set up. The kits are very beefy, clean and quality looking welds and coatings showing the price is not simply good marketing but solid components and attention to QC. We've towed just under 7,000 miles on the new set up so far and it's shown to have been worth the cost and effort installing for me personally. If we were to upgrade or replace this camper I would look to do this again without hesitation. Cost and effort comparisons to full independent suspension set ups and the upgraded equalizer options, which I did have the Road Armor on our lighter bumper pull and felt it was a great upgrade, but for this larger heavier unit I don't think you can find a better sweet spot of cost vs benefits than the full slipper spring and shock kits as this solution offers.
Love the system, I ended up installing it myself and I feel bridge transitions in my truck but not in my camper
The Roadmaster shocks and brackets all appear to be good quality. I say appear, because I haven’t road tested them yet.
The kit is very expensive, considering the shocks individually are not expensive. I considered making my own brackets, but I’m under a tight deadline.
The Axle bracket install is straight forward and relatively simple, because the axles are below the springs.
HOWEVER, the upper brackets are more challenging.
I’ve read on RV group sites that the “self tapping” bolts installed on the chassis top brackets can work loose, causing travelers to use a repair shop and weld them secure.
Self tapping bolts may not be a problem on a chassis that is 1/4” thick steel, but the Grand Design chassis appears to be 10 gauge (1/8”) “C” channel.
I elected to use grade 8 bolts and nuts, which required squeezing my hand into the underbelly covering and installing the washer, nut, and red tread lock from behind.
It’s a real knuckle buster and time consuming, but I feel much better about them not working loose from the constant vibration of the road surface.
BTW, I did consider welding, but there are wires and water pipes all in close proximity to the chassis.
Compression nuts are also possible, but bracket hole alignment must be perfect and I couldn’t do that without first dropping the leaf springs out of the way.
Other than that, I’m pleased with outcome so far.
Sent the double axle not triple axle
The shock kit just came today and I haven't a time that I will be installing it so no review just yet.
After one year these still work great. They made a great improvement in the ride in the cabin of my truck while towing since the fifth wheel movement is so much more controlled.
