Roadmaster Comfort Ride Slipper Springs

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.


Leaf Spring Setup

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.


Roadmaster Comfort Ride 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.


Roadmaster Comfort Ride Slipper Spring Rollers In Center Hanger Box

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.


Gas Shocks Absorb Road Vibration

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.


Roadmaster Comfort Ride Shock Absorber

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.


Roadmaster Comfort Ride Shock Absorbers Installed

Typically, when shocks are installed on a trailer, they're positioned at a more horizontal 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 a nearly vertical angle. As a result, these shocks will have the leverage necessary to limit up-and-down and lateral movement during both compression and rebound.


Rigorous Testing Standards

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

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.

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!


Comments
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.

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.

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

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

Installation was easier than expected. You need to be somewhat mechanical inclined when attempting this on your own. Invest in some good jacks and even the small jack stands to hold the axles. Ride difference was noticed on the first trip out. Would recommend this to anyone with factory standard suspension system. I also added the Reese Goosebox hitch and with these two together WOW what a difference. Wife isn’t complaining anymore of chucking and being jerked around. That’s worth the investment all day long.

This was absolutely the BEST purchase I've made for my fifth wheel to date, hands down. Went from having very rough chucking/porpoising/bouncing to a rig that drives like a Cadillac. Seriously. If you are having issues with this while pulling your trailer, THIS is the product to install. HIGHLY RECOMMEND!!!

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


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.


Comments
Great. On a 32 ft. WildCat fifth wheel..No problems. In the driveway, I installed the Shock system, heavier springs. I had to modify the shock-to-frame brackets, as the trailer has been raised 5 inches. Along with the MorRyde Stabilizers the trailer tows like a dream. Be sure to have the wet bolt grease nipples pointing out to the side of the unit for easier access. Next project will be to replace the scary Magnetic Brakes with a hydraulic system. Thanks etrailer. Kudos to your wonderful support crew. It was just like calling my buddy next door.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


We bought a new Grand Design 22 foot Travel Trailer and Ford Expedition Tow Vehicle. Even after we installed a Curt Trunnion Bar Equalizer Hitch, the trailer bucking was unbearable for long trips. It was so bad we were ready to sell the whole rig. The suspension of all travel trailers is sub-standard. We bought the Roadmaster RM-2450 Shock absorber kit and installed it ourselves. It made a WORLD OF DIFFERENCE in the ride! However, the installation was not easy for a 76 year old man. Thanks to a neighbor with a flat paved driveway and an extensive tool inventory, I got it done. You need pre-planning and high jack stands. Read the instructions and view some online videos before committing. Verify that there are no gas or water pipes next to the trailer frames. Determining the location of the upper shock frame bracket is tricky. This measurement sets the angle of the shock absorber, and has to be done BEFORE you lift the trailer and remove the wheels! You have to have the trailer loaded, the wheels on the ground and the tow vehicle connected. Then install one shock absorber from the bottom up and measure where the upper bracket sets on the frame. Then you can disconnect and lift the trailer up on jack stands and drill the frame holes. I was lucky that I was close to the IDEAL 35 degree angle on my trailer. I don't know what you would do if you are outside the 25 to 40 degree allowable range. The instructions say you have to get 12" long drill bits to drill into the bottom of the frame. There's not enough clearance to insert a standard drill between the springs and frame. Pushing the drill up overhead, and having the bit tight to the springs makes it almost impossible to get the holes straight. So when you drive the self tapping bolts into the holes it is very easy to strip them. A better solution is to have a low profile angle drill. Otherwise you'll be welding the brackets or glueing bolts. We also installed heavy duty shackles, wet bolts and bronze bushings while the trailer was up on the jack stands. You have to refer to other reviews for that. The Trailer Mfg. stock components are junk.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


Thank you for asking for a 1 year review as I never do them without enough test time. I have made several trips into western VA and West VA so have used the mountains and found it made a big difference in stability and bounce as advertised. No fault of the product but had I known I would have changed axles to next load level higher and kit to match. Instructions were pretty good, it does require some drilling through 3/16 steel 9/16" holes so having proper tools for job is essential. I got some trailer jack stands from [nationwide retailer] they provided safety at a reasonable cost. I highly recommend them.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


Highly recommend adding these on your camper. We added them to our Grand Design 2400 BH which was a night and day difference in ride quality. This eliminated a lot of the porpoising, chucking and side to side roll that you sometimes get. I was amazed how much smoother of a ride pulling the camper is now. Running these shocks now in combination with the Road Armor Equalizers.

What I like better than the products are the people and support received from EVERYONE I have talked to at etrailer. If Forest River was half this good, I might buy another one, but most of the questions or problems I have come across with our fifth wheel have been solved by someone here after talking to a generic moron at the manufacturer. eTrailer ROCKS!!!

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


I live in canada, the cost of the shock kit was xxx.xx Canadian cheaper than what I could buy it for in here even with the Dollar exchange and shipping, and I got it 7 weeks sooner than any other dealer I contacted here in Canada. The service from etrailer was excellent and the shock kit arrived on time as promised from UPS. Thank you etrailer for your excellent service, I especially liked the package tracking system. I was able to see the progress of my package from the time it was picked from the shelf to every step of the shipping process. I will purchase more from etrailer in the future now that I've experienced how easy the process is. *** If you are ordering from Canada insure you call etrailer and confirm the cost of Canadian to US exchange and the shipping cost. Remember that all figures are in US dollars.*** I have not yet installed the shock kit but I will update my review once it's installed and I've had a chance to pull the trailer.

I received the RoadmasterComfort ice Shock Kit today and have not had the opportunity to install the the kit at this time. However, upon opening the box of parts, I was impressed by the quality of the materials provided in the kit. That is a grand start, for good review of the Roadmaster Kit. Will provide more review once installed and tested. Thanks for the expedient shipment of the kit and the follow-up.

As always etrailer delivered a great product, complete and undamaged in record time. I received the Roadmaster -2460 shock kit for the suspension on my 2019 36 foot fifth wheel three days earlier than expected and completed the installation myself in approx. six hours. Anxious to take it down the road and see how much it has improved the ride in my coach. Great price, easy installation and good instructions for those mechanically inclined DIY's.


Comments
The Roadmaster - 2460 shock kit improved the ride in my 36 ft. fifth wheel, eliminating the rough ride and jarring we had been experiencing previously. We have traveled approximately 10,000 miles since the installation and are extremely happy with the performance.

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.

Well, all the shocks are installed. Working on my back is hard, not as easy to do stuff today as it was years ago but I got I done. Sharp drill bits and using the frame mounting plates as a guide was the key. However, I had so much dirt and metal bits in my hair I had to take my dogs flee comb to my head before I could shower. Now for the next project whatever that is. I’m sure I’ll think of something.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


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..

Arrived very well boxed, nice heavy brackets, fit well with exception of trying to get angle and length both correct. But after a bit of thinking and grinding and welding every thing worked out quit well. Will find out next week how much improved it will be, as we start our annual long trip estimate about 12,000 miles this trip out.

Ask the Experts about this Roadmaster Trailer Leaf Spring Suspension

  • Will Using Leaf Springs With A Different Amount Of Leaves Be Okay On My 2018 Vanleigh 5TH Wheel?
    The number of leaves on a leaf spring is not the only determining factory in the amount of weight it can handle. The thickness of each leaf as well as what the leaf is made out of can affect the weight rating and performance of the spring. The Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570 does use 5 leaves that are 3/8" thick. Each spring is rated for 3,500lbs which is 7,000lbs per axle. This kit upgrades your suspension by allowing the axles to act independently...

    In order to determine which leaf spring upgrade kit will work on your Grand Design Solitude you will need to know what size axles and how many axles you've got on the trailer. You can determine what axles are on the rig by checking the sticker/plate on the axle tubes; these identifiers will tell you who made the axle, its' capacity and/or diameter and will determine which suspension system is going to work best for you.

There really isn't an advantage to going with higher capacity leaf springs than needed. If the suspension is too stiff it doesn't really do it's job well as the ride would be rougher. Best recommendation I can make is to stick with the correct rated suspension you have on your trailer and then to not exceed the weight capacity...

    For your 2020 Grand Design Reflection 150 Series 240RL with 4400 lb axles the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers - Tandem 7K Trailer Axles Item # RM-2460-2570 is not compatible. I recommend Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers - 3,500-lb Axle Item # RM-2450. As far as a disc brake kit. There would be no way for me to know what modifications have been done to the axles. The Titan Disc Brake Kit and BrakeRite Electric-Hydraulic...

  • Dimensions of the Roadmaster Comfort Ride Slipper Spring System
    I went out to our warehouse and measured one of the Roadmaster Comfort Ride Slipper Spring System like part # RM-2460-2570 for you. The box is 3-1/4" wide and the opening is 3-3/4" long x 2-3/4" wide. I have attached a photo of these measurements for you as well. According to my contact at Roadmaster, the center leaf spring hanger will need to be between 3" - 3-1/2" from the bottom of the frame to the center of the bolt hole. If the hanger you have will not work with these measurements...

    Roadmaster makes the leaf springs of the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570.

  • Which Roadmaster Suspension System for 2018 Grand Design Reflection 150 Series 5th Wheel
    We don't have these parts fit guided for individual trailers, but as long as your 2018 Grand Design Reflection 150 5th Wheel trailer has tandem axles with a 7000-lbs each capacity, the Roadmaster Comfort Ride # RM-2460-2570 is the correct suspension upgrade for you. If you've got a triple axle trailer with 8000-lbs axles, the correct kit would be the # RM-2470-2580-3. You may want to check your axles for the spec sticker, which will tell you exactly what the capacity of your axles is....

  • Where is the Steel from for the Roadmaster Comfort Ride Kit w/ Shock Absorbers
    I spoke with my contact from Roadmaster and she said that the steel used for the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570 is from America. Although American steel tends to be stronger, when it comes to leaf springs the biggest mistake people make is overloading them which does cause them to wear prematurely to the point of failure. No matter what kind of leaf springs you install on your trailer be sure that you stay within the weight ratings...

  • Could Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570 Fit 2017 Sandpiper
    The distance you have between the axles of your Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570 that you referenced is perfectly fine. I am not sure exactly which model of 2017 Sandpiper you have but as long as the axles each have a capacity of between 5,200 and 7,000 lbs this kit will fit and work great. Your trailer will have a much smoother ride quality overall with this than what you have now so it's a great upgrade.

  • Is Lubrication Required for the Roller Pin on the Roadmaster Comfort Ride Slipper Spring System
    I spoke to my contact at Roadmaster and they stated that the roller pin on the Roadmaster Comfort Ride Slipper Spring Systems do not require lubrication. They stated that if you felt it were necessary, you could add some grease to it but this would be more for noise reduction than wear prevention. The bolt that holds the roller pin in place is not a wet bolt nor does it need to be. The roller pin does not act like a bearing, therefore does not require lubrication. It only rotates back and...

    Both the Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570 and Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2470-2580 technically have 5 leaves.

  • Recommended Solution to Beef Up Suspension Hangers
    I may have a solution for you, but I'm not directly aware of any reinforced hanger system; it might have been something that's custom fabricated. However, it's also possible that they've just replaced the spring hangers with something like the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers - Tandem 7K Trailer Axles # RM-2460-2570, which has a much larger and stronger center hanger. If you can come up with any pictures of that you've seen I am more than happy to...

  • Can you Explain Why the Roadmaster Comfort Ride Leaf Spring Kit Does Not Use a Suspension Equalizer?
    The Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570 that you are looking at is designed to allow each axle to act independently of the other, similar to the way torsion axles work. While it uses slipper springs to achieve this on your trailer traditional tandem axle slipper springs systems will still offer an Equalizer like # HAP-203-01. I do recommend using equalizers with your leaf spring suspension whether you have double eye springs or slipper springs, as they...
