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.

The Roadmaster Comfort Ride Shock Absorber kit on our Forest River Surveyor travel trailer was a great upgrade on our travels on rural highways and areas with wind. On our trip last fall from the Oregon Coast to Northern Idaho was a good test of this system and made for more relaxed driving! Should be installed at the factory!

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


Excellent product! Absolutely TRANSFORMED my towing experience! Installed on a 2017 Open Range 310BHS travel trailer. Approximately #10,500 loaded. Trailer doesnt bounce or jolt over the road. Ride is substantially bettter. System is tough, thick, and seems it will last. Instructions are pretty clear, and all tooling neede is pretty basic. I reccommend a digital inclinometer to be able to set your shock angles precisely. They're cheap on [online]. I reccommend this kit to every single person who has the same bouncing issue. Could not be happier with the purchase!

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.

Installation Review (will update after road test) Great tutorial video. Highly recommend a quality bolt/nut loosening solution. Makes a big difference. Rented an angle drill for the top bracket 5/16th" holes due to low clearance (I ended up buying one it was so useful). Job went smoothly. I wouldn't cut your underbelly until after the install. I may not cut mine at all. Top of shock pushes against it but that shouldn't cause a problem. I added a number of photos, to include the solvent and jack. Top notch company with high quality merchandise.

I would recommend this over other type upgrades. It may cost more but like the saying goes you get what you pay for. Install was not difficult.Installed on a 2015 Fuzion 325 toyhauler,towability plus road jarring much improved having ridden in trailer before and after,you can sit in the rear in your seat and not get thrown out.The other notable upgrade was the reese goose box fith wheel hitch,a real good upgrade.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


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.

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..

Still feel it is the best upgrade you can do short of going independent. Still a great product for the price.

I've installed this on a 5th wheel about 1 year ago and I have to say I've been very pleased with this purchase. While stuff in the trailer still gets out of place, it feels like it has improved the handling of the trailer over rough roads and during windy conditions. I've probably put about 5,000 miles on my trailer after installing this kit and have to say I have no regrets with this purchase.

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.

One of the best things I’ve installed on my travel trailer. They smoothed out the ride and removed the sway from my trailer. Every travel trailer made should have these installed on them at the factory.

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.

  • What is Stopping Side-to-Side Movement of Leaf Springs of Roadmaster Comfort Ride For 8K Axles
    It is a combination of the U-bolts and the tie plate that stops the lateral movement of the leaf springs in the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks - Tandem 8K, 3-1/2" Axles # RM-2470-2580. They are tightened down, and the spring itself won't be able to move from side-to-side either on the axle, or inside the slipper spring box of the # RM-2470-2580. So yes, this kit will fit so long as you do have the 3-1/2" diameter axles on your trailer.
