Rough roads and long hauls can shake everything in the trailer. The heavy-duty gas shocks in this kit absorb up to 50 percent of the vibration and impact before it reaches the frame. Each shock measures 17-1/2" extended and 11-1/2" compressed, using nitrogen-charged cylinders that limit both compression and rebound. The result is steadier tracking, less sway, and a quieter tow on pavement, gravel, or cobblestones.
When one axle hits a bump, traditional equalizers move that energy to the other—causing bounce and tire lift during braking. The Comfort Ride design isolates the axles with center hanger boxes so each spring works on its own. That isolation prevents axle roll-up and keeps all four tires planted, improving traction while braking by as much as 70 percent. It means a safer, more predictable stop every time.
Standard equalizers pivot and transfer shock through the frame. These 27" longx1-3/4" wide slipper leaf springs slide quietly inside the center hanger box between a roller and safety bolt. As the trailer moves, the roller translates up-and-down motion into smooth front-to-back movement. The five-leaf, 3/8"-thick springs each carry 3,500 lbs and use pressed-in Never Fail bushings that need no grease or maintenance.
Each spring eye comes fitted with molybdenum- and graphite-filled bushings, tougher than brass or nylon and designed to run dry without squeaks. The bolt-on hangers fit 3"-diameter axles—typical of 5,200- to 7,000-lb setups—and include all mounting hardware. With four slipper springs, two center hanger boxes, and four shocks, the system installs cleanly using existing hangers and a drill for the frame brackets.
This suspension has passed Finite Element Analysis and real-world proving-ground tests to ensure long-term durability. The limited lifetime warranty backs the build quality, so once it’s installed, your tandem-axle setup stays solid and smooth mile after mile.

Order filled and shipped on a Sunday afternoon, now that is customer service!
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.
etrailer rocked, their support was knowledgeable and shipping and delivery times were better than expected. Great product line and value add.

Hey, thanks for saying that, Kevin! We really do appreciate it. We do the best we can so you always get what you need :)
After 1 year we are still very pleased. Have about 5000 miles towing and it is a much better ride. Worth the money. Ride is much better. We did have it professionally installed. It's a pretty big project for a driveway mechanic

Continues to perform very well.
We made our trip from Florida to Utah and back and we didn’t have the rear blinds falling off as it rode much smoother! Much easier to maintain too!

That sounds like it was an awesome trip you went on, Terry! I'm happy that the handling is better so that longer trips are in a way, smooth sailing. Do you have an fun trips planned for this summer?
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.

Wow, already been a year since install??!! Have put near 1k miles on since install and ride has been amazing. No more broken drawers in the back of the camper and most items in cabinets tend to stay put. Im a little concerned about the slack in the slipper spring, the side to side movement specifically, and what wear that could cause to the tires, but only more miles will tell to the tale. We do get an annoying suspension squeak from the pads that ride on the leaf springs. I found some silicon spray will quiet it down for a while so that has become a monthly maintenance item so it doesnt sound like a 20 year old POS in the campgrounds. We recently upgraded to a dually as well as upgrading the pinbox to a Reese Goosebox and have a really good ride on these crapy CO roads. All in all still very happy we did the upgrade.

Installed it today 5/30. Everything works as advertised.
Good product, was missing a few key pieces that were important for final installation. Contacted the manufacturer and they resolved the issue, but took their sweet time in getting me the replacement parts needed. Other than that little snafu, everything went great and the system has made a positive improvement in the trailer handling. Highly recommend.
Ridiculous... I spent all that time and money. Cracking my head on the bottom of my fifth wheel while crawling around underneath it. I said ridiculous because when I took it for a test drive, it exceeded my expectations! Worth every penny and the headaches! It feels just as if I have a heavy load in the back of my pickup. There is no bucking and the only bumps I feel are what is under my truck tires. Couldn't even feel rumble strips in the road when coming up to a stop sign. I told my wife that I will not own a double axle trailer without a comfort ride system again!

You had me worried for a second, Cory! I'm glad that even through all the crawling and head banging, it was all worth it in the end!
great product, I'm a fabrication/designer, well thought out and much better than the original factory suspension. I also added structural kickers to the suspension hangers to help side load generated while turning and not relying on the hangers for strength. I also replaced the original factory u bolts, might as well have all new going back on
I love the new suspension system ! definitely noticeable when pulling our 5th wheel down the road, handles well, items stay in place inside the majority of the time. Finally a smoother ride.
Install is not bad and really good quality product. Should be a dramatic improvement over what I had.
Makes trailer pull and the truck ride s moother
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.
The kit assembled well. Maybe a few missing washers due to shipping damage. Only 6 miles on the trailer but they felt much smoother. So for now I would buy again, but I would pay to have them installed. I’m getting too old!

I hear you, brother!! Keep on keeping on!
After one year of using the comfort springs I can say they are one of the best upgrades we did for our trailer! It pulls better now, and the truck handles the bumps so much better. The comfort ride are certainly the best value for suspension upgrades. I was hesitant to install them myself, but the instructions were well written and easy to follow.

That is awesome, Joe! Really glad to hear you were comfortable enough to go for it yourself and tackle install. Probably saved a lot of money that way too :) Have you done a lot of traveling in the last year?
The product arrive in about two days. I will have them installed February 3. I just hope all the pieces are there. The springs box was destroyed during shipping, but the smaller boxe and shocks box was still sealed

I wish there were clearer instructions so we don't have to disassemble and reassemble. Questionable torque instructions.
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!

This was the best thing I could have done to make the 5th wheel experience a good one. Prior to installing failing to properly secure things in the trailer would not end well. After the install, items remained where they were last placed.
The comfort ride system in my opinion is far superior to the standard leaf springs system. With fewer moving parts and the ability to act as an independent suspension system it outperforms the standard leaf springs.
We've run about 7,000 miles since we installed the Roadmaster Comfort ride kit. I can definitely tell that the 5th wheel doesn't bounce as much as it did with the CRE 3000 suspension. And I haven't had any tire issues since installing either.
Working great on my 2930rl solitude 5 thousand miles so far
Really made a big difference in ride and smoothness, things don't get thrown around the 5th wheel anymore. Great addition

Really like the Roadmaster comfort ride suspension. It greatly reduces movement of products inside the 5th wheel while towing compared to the original CRE 3000, often on decent roads nothing moves at all, on rough roads still some movement but nothing like before. Strongly recommend
By far the best upgrade to our 5th wheel RV. It pulls and rides like a dream now.

Love the pics! Now that you got your ride quality under control. Where are you taking the RV this summer?

After a complete frame rebuild and reinforcement caused by weak factory suspension. There is no question the Roadmaster suspension is still the best upgrade we have done on our 5th wheel RV.
Very Happy with the Roadmaster Suspension! A must have item! (Along with my previously installed X-Factor cross braces)
Anything to smooth out the beating that our US roads provide, is a good thing for both the 5th wheel frame/structure and our contents inside. Thank you etrailer and Roadmaster! 2022 GD Solitude 310GK. Note: Frame repair plates in photos were to repair 3" frame cracks that formed prior to installing Roadmaster and X-Factors.

Hmmmm, you should definitely not be having issues with it coming loose, especially so often. I have gotten in contact with the manufacturer and they believe that this sounds like an initial install issue. It could be that the factory tie plates were installed on the top of Roadmaster's. It could be that they were not properly torqued. As for the U-bolts; yes, they would suggest replacing the U-bolts and the lock nuts. According to Roadmaster, they would like to speak with you personally to do some additional troubleshooting with you and get to the bottom of the issue. I will send you their contact information in a separate email.
