Features to know about

Better Control Under Braking: Independent Axle Operation Boosts Traction up to 70%

When heavy braking causes axle roll-up, traction drops and handling suffers. The Comfort Ride system stops that by isolating each axle so they work independently. The center hanger boxes replace standard equalizers, keeping shocks from transferring between axles. That design increases braking traction by as much as 70%, making your setup safer and more stable on the road.

Smoother Towing on Rough Roads: Heavy-Duty Gas Shocks Cut Bounce and Sway

Harsh bumps and vibration can make towing exhausting. The included heavy-duty, nitrogen-charged shocks absorb road vibration and reduce bouncing, chucking, and porpoising by as much as 50%. The adjustable mounting brackets keep the shocks at the right 20- to 40-degree angle for maximum damping on both compression and rebound. It all adds up to smoother tracking and a ride that feels steady and controlled, even on uneven terrain.

Quiet, Controlled Ride: Slipper Springs and Rollers Eliminate Harsh Motion

Traditional equalizers send every bump through the entire suspension, causing noise and sway. The 27" long, 1-3/4" wide slipper springs in this kit slide into center hanger boxes instead. Each box has built-in rollers that stop the spring ends from hopping and translate up-and-down motion into smooth front-to-back movement. The result is a quieter, more controlled ride that keeps the trailer steady and the contents secure.

Long-Lasting Hardware: Maintenance-Free Never Fail Bushings with Molybdenum and Graphite

Worn bushings are a common cause of squeaks and sloppy handling. The Comfort Ride uses maintenance-free Never Fail bushings pressed into the spring eyes, built from molybdenum and graphite. They’re more durable than brass or nylon and never need greasing, so the suspension stays tight and quiet with less upkeep.

Built to Handle the Load: 4,000-lb Springs for 3" Triple 8K Axles

Each 27" leaf spring has six 3/8"-thick leaves rated for 4,000 lbs, fitting 3" diameter axles for triple-axle setups. With 6 slipper springs, 4 center hanger boxes, and 6 shocks included, the system provides a solid, balanced foundation for heavy-duty use. It’s a simple bolt-on installation designed for long service life and a smoother tow every time.

Great product. Easy install, just make sure you read the instructions thoroughly prior to starting your replacement.
by:
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.

Glad they are working well for you, Dillon! I don't think I have ever heard a bad review of this system as it just gets the job done! ^___^ What did you install it on?

by:
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.

That's great to hear, Norm! How often are you out towing the camper?

by:
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.
by:
By far the best upgrade to our 5th wheel RV. It pulls and rides like a dream now.

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.

by:
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?

You really put this kit to the test! How was Alaska?

by:
Love the way the trailer reacts to the bridge ramps and bad roads with the RoadMaster Comfort Ride system. When the camper bounces over a bridge ramp it settles down immediately. There is virtually no side to side rocking while going down the road.
by:
Working great on my 2930rl solitude 5 thousand miles so far
by:
These work great, so much better than stock leaf springs. I had to replace the Stock Springs twice. So far these are holding up very well. It’s been a year.
by:
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.
by:
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:
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.
by:
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.
by:
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.
by:
This kit was relatively easy to install with a little mechanical knowledge and tools. Definitely a great upgrade to most OME suspension systems.
by:
The system is well designed and was easy to install. The only items missing from the kit that are needed are new u-bolts, the old ones are too short for the new heavy duty hardware and new ones should be included with the kit.
by:
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.

by:
I am very happy with the Roadmaster suspension kit I installed on my Toy Hauler.
The leaf springs are much more beefier than the original leaf springs and I do not worry about broken springs anymore. I have to think the shock absorbers are making for a much smoother ride going down the road and everything inside the trailer is being protected from the constant vibrations.
by:
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.
by:
This is a great suspension upgrade for your camper. The ride quality after installation is much improved, noticeably smoother towing and no more worries about bust leafspring or shackles. Took about 4 or 5 hours to install with basic tools in my driveway. Definitely recommend upgrading.
by:
I have had the suspension kit on for over a year now and I would do it again. The springs and all the hardware seem to be of much higher quality that the OEM stuff that was on the trailer. After the install, (which I did myself. Not a real hard job) the camper rides and tows much smoother. between the slipper springs and adding shocks the stuff inside the camper is pretty much where it was when we packed it. So I am hoping it will extend the life of the camper by not beating itself to death when towed.
by:
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?

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

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.

  • Difference Between The Roadmaster Comfort Ride Kits RM-2460-2580-3, RM69NQ, And RM-2460-2570-3
    I can definitely help with that, Larry! There are differences between the Roadmaster Comfort Ride Kits # RM-2460-2580-3 # RM69NQ and # RM-2460-2570-3 and I have them listed below. They all include the Comfort Ride Shock Absorbers for Tandem Axle Trailers - 5,200-lb to 7,000-lb Axle # RM-2460 and Comfort Ride Add-On Kit for Triple Axle Trailers - 5,200-lb to 7,000-lb Axles # RM-2460-50, but the leaf springs between them are all different. # RM-2460-2580-3 Roadmaster Comfort Ride Slipper...

  • Which Roadmaster Comfort Ride System is Recommended for 2025 Brinkley G3250
    Hey Robert, since they are near 22k I would recommend going with the 8k triple axle kit part # RM-2460-2580-3 as that would be the properly rated system. 22k divided by 3 axles is 7,333 lbs so you would need more capacity than 7k per axle so that would be why the 8k system is your best bet. Your customer is just wanting a more comfortable ride quality?

  • What Comfort Ride Kit For Toy Hauler With Triple 8K Lippert Axles
    Hello again, Dan. Since your toy hauler has triply 8K axles I do have to recommend going with the 8K Comfort Ride Kit # RM-2460-2580-3. This comes with the 4K rated leaf springs and the leaf springs should always be rated the same as the axles.

  • Can 2019 Grand Design Momentum 381M be Upgraded to 8K Suspension Parts in Stages
    Hey Kyle, good to hear from you again! You can definitely upgrade the suspension components on your 2019 Grand Design Momentum 381M in increments because the 7K and 8K brakes match enough that it can work out that way, you just need to make sure the bearings for your current brakes will match up with the 8K axles when you purchase them. We unfortunately don't carry any axles rated higher than 7K so you'll have to take the bearings numbers you currently have with you to your local RV dealership...

  • Can A Roadmaster Comfort Ride Suspension Be Installed A Trailer That Rides Slightly Nose High
    Yes, you can still install the Roadmaster Comfort Ride Leaf Spring Suspension Kit even though the trailer rides slightly nose high when coupled to the tow vehicle. When installing one of these kits you'll most likely need to get longer U-bolts since there typically aren't enough threads to accommodate the additional mounting brackets. To determine the right kit and U-bolts you'll need to know the capacity and diameter of your axles and how many axles your trailer has. 3.5k 2-3/8" Tandem...

  • Availability of 8k Roadmaster Comfort Ride Triple Axle Setup for 2020 Grand Design Momentum 399TH
    Yes, we do have a triple axle Roadmaster Comfort Ride kit for 8k axles with the part # RM-2460-2580-3 which is for 3 inch diameter axles. Since you have 7k Dexter axles that would mean you have 3 inch diameter axles. This would make a huge difference in ride quality and performance on your 2020 Grand Design Momentum 399TH. You should note that just because you will have more suspension capacity the overall capacity of the trailer would not increase.

  • Best Suspension Upgrade for 2009 Keystone Raptor 361LEV
    Since your 2009 Keystone Raptor 361LEV has a triple 7k axle setup the best solution I can recommend to replace and upgrade the suspension is the Roadmaster Comfort Ride system part # RM-2460-2580-3 which replaces everything and gives you a much smoother and more cushioned ride since it adds shocks to the suspension which makes the biggest improvement you can make.

  • Roadmaster Comfort Ride System for Triple Axle Trailer with 8k Axles and How Many X-Factors Fit
    Since your trailer has three 8k axles the complete Roadmaster Comfort Ride system you would need is the part # RM-2460-2580-3 which is compatible with the MORryde X-Factor crossbeams like part # MR33WR. Since the X Factor would only be able to fit on the outside hangers you'd want to run two of them. One at the front of the suspension and one at the rear.

    Hey Kyle! The Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks # RM-2460-2580-3 can be used with disc brakes like the Kodiak Disc Brakes # KOD67VR but aside from that we unfortunately don't have any 8K axles - the heaviest we have is rated for 7K. For something more in that HD range you'll need to have a trailer shop or RV dealer custom order an axle for you.

The spacers install on the front and rear axles to compensate for the shorter hangers so you can install the triple axle system. For the Comfort Ride itself, you will need one of the following based on your axle capacity and diameter: -Roadmaster Comfort Ride for Triple 7K Axles - 3" Diameter # RM-2460-2570-3 -Roadmaster Comfort Ride for Triple 8K Axles - 3" Diameter...
