Rough pavement and washboard surfaces can toss a trailer around and make towing stressful. This kit’s heavy-duty, nitrogen-charged gas shocks cut that motion by up to 50 percent, calming bounce, chucking, and porpoising. Each shock measures 17-1/2" extended and 11-1/2" compressed to give plenty of travel for rough roads. The result is steadier handling and far less movement inside the trailer when the road gets uneven.
Axle roll up during hard stops can lift the rear tires, losing grip when it’s needed most. The Comfort Ride’s center hanger boxes isolate each slipper spring so the axles work independently, preventing shock transfer between them. That design increases traction by as much as 70 percent during braking, giving noticeably more control and stopping confidence.
Traditional equalizers let vibration pass between axles, creating a harsh wave of motion. The Roadmaster setup replaces those with fixed center hanger boxes that hold the flat end of each 27" long, 1-3/4" wide spring between a roller and safety bolt. The built-in roller keeps the spring from hopping inside the box, turning vertical hits into smooth front-to-back movement for a quieter, more stable ride.
Frequent greasing and worn bushings are a common annoyance on factory suspensions. These springs come with maintenance-free Never Fail bushings already pressed into the 3/4" eyes (9/16" without bushing). Made with molybdenum and graphite, they’re tougher than brass or nylon and won’t squeak or seize up over time—just install them and forget about them.
Installing this system doesn’t require welding or fabrication. The kit bolts over existing hangers using supplied hardware and fits standard 3" diameter axles, typical of 5,200- to 7,000-lb ratings. Each leaf spring supports 3,000 lbs and uses five 3/8" thick leaves for strength. Four shocks, four springs, and two center hanger boxes come included for a complete tandem-axle upgrade that’s ready to bolt on and go.
Ratings & Reviews
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.
Easy install in the driveway, completed in 2 evenings after work. This kit changes the way the trailer rides and it was very noticeable. We have a 17,000lb toy hauler with a Reese Goosebox hitch, the hitch made a difference but due to the factory suspension we would still feel every jolt on the road. Once this kit was installed and accompanied by our new G load range tires, the fifth wheel feels more planted to the road and has minimal sway or fore and aft movements. Definitely worth the investment.
Really made a big difference in ride and smoothness, things don't get thrown around the 5th wheel anymore. Great addition
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.
Etrailer sent the spring kit in a timely manner. I had help for shipping from support because the 8k springs seemed to be out of stock so I had to switch from the 7k I originally ordered. We got it sorted out eventually, thanks Etrailer! Roadmaster has a good price for a suspension kit and not much difference in price between the kits, which is why I opted for the heaviest. We carry a lot of stuff as full time Nomads! It came in two heavy boxes, so I took the parts out to move them around. The instructions were pretty good, a couple spots required some head scratching. I did not lift the whole trailer up at once but did it one side after another. Probably would have been a little easier to lift the whole trailer to line things up. The kit worked as expected, very robust. We have traveled the country and up to Alaska with the springs and so far, no complaints! I opted for the heaviest kit 8K which might be overkill for my 7K axles, so the ride is a bit more rough/stiff that our previous experience with the poor flat out springs and shocks on our Arctic Fox 295t. New things bounce around, but that is life in a trailer, right?
By far the best upgrade to our 5th wheel RV. It pulls and rides like a dream now.
Possibly the best upgrade for any camper. No more road seam feedback to the truck, everything inside the camper stays put during travel. If you're questioning if it's worth the cost, it it. Roadmaster customer service was very helpful with getting the correct kit identified.
Just received today, package in good shape, fast delivery, excellent service.
Thank you
Ride has improved
I installed the kit went on pretty easy shocks are a little bit harder because the arrangement of the angled spacers but not to bad. It does change the ride less bounce when going over rough roads
Upon a recent inspection of our 2017 Sandpiper Select 329RE fifth wheel suspension, I noticed the stock nylon bushings in the springs were beginning to fail. Instead of replacing everything with the stock, outdated equalizer system, I decided to upgrade to the Roadmaster slipper spring with shock absorber system. I also decided to install MORryde X-Frame crossmembers to the front and rear spring hangers for added stability and support. Sounds easy enough, right? I ordered both systems, and also asked three different people, in three different chat sessions if the Roadmaster system came with U-bolts; because all images showed they were in the kit. All three people told me they did not. No big deal, I just ordered new U-bolts too.
I get all of the parts I ordered, which was fairly quick, jack up my RV, and start laying parts out. First I saw that the shock absorber kit did in fact include new U-bolts. And then I saw the slipper springs were rated for 2500#. My fifth wheel has 6k Dexter axles. Dang! I ordered the wrong kit! I cam back to the etrailer website and chatted with someone about my mistake. I was told to send the entire Roadmaster kit back for a refund, but I could reorder the correct kit. I would just need to buy it again first. So I did. The one I needed was RM49NQ for 6K axles. So I ordered that kit for another $2,010 and sent the other back for a refund.
The I receive the 'correct' kit and I open the slipper springs up, see they are rated for 3000#, but they only have four leaves. The specs show they were supposed to have five leaves. A call to Matthew at etrailer resulted in me being sent a new set of slipper springs - at no charge - and I would ship the ones I had back. Still no big deal, right? In the meantime, my RV has been jacked up, with the wheels off for about 3 weeks now. And we have a Labor Day weekend booked at the forgotten coast coming up.
The replacement springs arrive and they are exactly the same as the ones I had; four leaves, not five. Another call to Matthew, but I also called Roadmaster to see what was going on (my brother's suggestion). Roadmaster tells me, "yeah, we changed the configuration on those and put a longer bottom leaf on them, so they only have four leaves now." So I shipped the latest received springs back and I'm all set. Not so fast, my friend; as coach Lee Corso used to say. I start doing the upgrade and everything is going really well, until I start to put the rear X-Frame crossmember on. That one had to outer spring hanger brackets in the kit, instead of an outer and an inner. Foiled again! A call to MORryde that next Monday morning, and they shipped my the inner bracket out that same day. I was able to complete the job and I am looking forward to seeing how much better the ride is on the way to our camping destination Labor Day weekend. I noticed a pretty good difference when we test drove it a little bit after the upgrade was finished. I gave five stars because of the fantastic customer service I received from everyone at etrailer I spoke/worked with!

Holy moly! I'm sorry you had such an ordeal getting the Comfort Ride installed and we really appreciate your patience with us. The Roadmaster Comfort Ride system is the best suspension upgrade around, and I think you'll be really happy with it when your headed on your trip! I must admit though, I haven't heard of the forgotten coast, where is that?
I am very impressed with this kit. The quality of the pieces are exceptional and the instructions are easy to follow and understand. I did it with no help, just take your time. I hope it helps improve the ride of the camper to help soften our horrible roads and reduce the strain on the camper.
The Roadmaster system is a very robust, well-engineered system. I have not towed with it yet but can only assume, because of the design, that my towing experience will be greatly improved.
Had this system installed on 2021 Vanleigh Pinecrest 330MKP by Prestige Trailer Solutions Hudson,Fl Extremely happy with the install and product.Noticeably smoother ride,very little chucking and tires no longer hitting outriggers going over bumps.
