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.

Review from a similar Roadmaster 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.. 630834

Review from a similar Roadmaster Comfort Ride in Trailer Leaf Spring Suspension


I installed this shock kit along with the Roadmaster RM-2560 Slipper Spring System in our 2011 Keystone Cougar 245RKS. As the model number implies, this is a rear kitchen unit. I had over 30,000 towing miles on this trailer and the bouncing trailer caused many issues: doors opening, dishes (and other items) getting thrown around inside the cabinets, many loose fasteners, etc. I had always wanted to add shock absorbers, but this new Roadmaster kit prompted me to replace the springs as well as the shocks. Our trailer has 4500 pound axles, so I was somewhat concerned that the shock kit was designed for 5200-7000 pound axles. But the Roadmaster people assured me that the kit would work fine with the 4500 pound axles, and it does! I did a quick calculation that showed that the new springs are about 14% stiffer than the originals. The shocks easily accommodate the slightly stiffer springs. The kit was relatively easy to install, but you will need multiple jacks and floor stands. Care needs to be taken to get the mounting holes for the spring box correctly located and drilled for simple installation, and my experience went fine. The ride height was very minimally affected - the kit has multiple mounting holes that help with this. And, I was able to use the original u-bolts to mount the new springs, although the instructions implied that I might need longer bolts. We have recently returned from a 7000 mile trip and I am very pleased with the Roadmaster kit. The ride improvement was immediately noticed and things do not get bounced around nearly as much as before. The trailer is also noticeably more stable and not affected as much by wind and passing big rigs. It is really great to get rid of the equalizer link that tied the ends of the original leaf springs together in the middle and allows the trailer to have a proper independent suspension. 614184

Review from a similar Roadmaster Comfort Ride in Trailer Leaf Spring Suspension


I installed the RoadMaster shock system on my new 30 foot fifth wheel because the first time we took the new trailer out (before shocks), the trailer bounced so much that the bouncing broke some plates in our rear kitchen cabinets. The product was straight forward to install. The only hard part was all the drilling into the frame to mount the top brackets. Working on my back, under the trailer, and around the springs with hot metal shavings dropping on my face was not pleasant. However, the installation was fairly straight-forward and the product seems to be very sturdy. I have not taken the trailer out to test the system yet but have two trips planned near term. However, based on how well my previous 5th wheel rode with shocks installed, I fully expect this installation to be well worth the money and I believe it should solve my bouncy trailer problem. 560561

Needed a bit longer bolt than was provided on a trailer. These bolts added the extra length I needed and were a perfect fit. Didn’t have to bend them open or closed to get them through the tieplate holes. 603632

I got my parts yesterday and everything was packed properly and all there. The instruction sheet with a complete parts list along with bolts and other parts. It will be a few days before I install the kit but from the instruction sheets and the u-tube video, I think it will be a simple job to accomplish. E-trade seems to have made the kit and system for anyone with simple tools to install. Thank you for your quick shipping. 595032

  • Should Pin Box or Suspension be Upgraded to Reduce Jarring and Bouncing While Towing
  • A cushioned pin box, like the Trailair Flex Air 5th Wheel Pin Box # LC328492 for a Lippert 1621 replacement that you referenced, will greatly improve the ride between your 2016 Ram 3500 and your Forest River Chaparral 37FL whereas upgraded suspension parts on your trailer are geared more towards the ride quality of your trailer. If the jarring that you are getting is from the trailer bouncing around then I recommend starting with suspension enhancement. From the info you gave it sounds...

  • What Difference Between Dexter 7k and 8k Axle
  • Typically a Dexter 7k axle will have a diameter of 3 inches and an 8k axle will have a diameter of 3-1/2 inches. The thicker the axle the more weight it can handle. 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...

  • 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.

  • The Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570 will work perfectly on the 7,000 lb axles of your Grand Design Solitude as it was specifically designed for 3" diameter axles with that rating. The 8,000 lb kit # RM-2470-2580 is designed to fit 3-1/2" diameter axles and would not work on 7,000 lb axles with a 3" diameter. It is certainly natural to wonder but there isn't any additional margin required as this system meets the ratings for your axles. The Roadmaster...

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.
