Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Are tired of finding all your stuff strewn about inside your camper and want to eliminate the road shock that causes it
  • Find that equalizers forcing one axle down when the other goes up (and vice versa) jostles your trailer around
  • Want to increase your braking performance so panic stops aren't so panicky

No, if you:

  • Have limited time, tools, and/or space to get this installed - you'll need several jack stands, power tools, and possibly a metal cutting tool
  • Have a car hauler or other trailer that you want to keep low

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.

Love the comfort ride system! Definitely greatly improves the ride. Pulling a 30ft. Camper with a half ton truck. Used to get a lot of the porpoising now it has almost eliminated it. Very noticable. Took longer than I thought it would for install....but got it done in a long weekend. Customer service was great.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


Great kit, really beefy high quality components, nice powder coating. Because my axles are above the leaf springs which I believe is relatively rare, the kit needed some modification, not too bad if you're handy and have additional tools. This kit is a no brainer for axles underneath leaf springs, pretty much bolt on from seeing the eTrailer videos, dramatically improved ride quality on my 20 mile test drive, looking forward to our next trip.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


Install wasn’t bad. Grand design welds a V bracket inside the spring hangers for more strength so that was my only challenge on install. This caused a problem on the center hanger as the spacer wouldn’t fit. Had to grind about a quarter inch off the spacer so it would fit as I could only bend the bottom of the hangers so much. Will be towing about 100 miles this weekend so it will be nice to hopefully not have broken drawers in the back of the trailer as well as shelves in the fridge door dislodged. I also did the X factor cross braces on the front and rear hangers for more strength. Will post back after we get more miles on it, but given all the other positive reviews I don’t think I’ll be unhappy.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


An amazing product. Very heavy duty with all the parts and great directions.


Comments
A simply amazing product! This shock absorber kit saves the trailer from the beating it would otherwise take. And, it takes a lot of the pressure off the leaf spring support brackets, which is a major added benefit! And it makes for a much safer ride and tow. We noticed an immediate difference ny the significant reduction of tow vehicle pull and sway that we experienced that was being caused by the trailer reacting to road and environmental conditions and influences prior to the installation of this kit.

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!

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


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.


Comments
Well its been two2 seasons with the Roadmaster shocks installed on our tandem axle, 9500lb travel trailer and I think they are a Great investment for anyone that pulls a travel trailer. I had mine professionally installed at a local trailer repair shop. They welded the upper shock mounts to the frame, and they did a fantastic job. I must also say that at the same time I had new MORIDE Wet pins and bushings and new Lippert Road Armor Equalizers installed. This season we were able to travel to the Province of Alberta, and anyone who has traveled Albertas roads, you know how Rough they can be. This rough ride is greatly exaggerated when pulling a travel trailer. The last time we were in Alberta was before the suspension upgrades and it was a terrible ride, so rough that it was difficult to drink a coffee in a travel mug for hours. This time the ride was Greatly improved as was the cornering . I could comfortably sip a coffee as we bumped along. Now there are some heavy road dips in Alberta that even the best suspension money could buy, couldnt soak up completely, but with the Roadmaster shocks it made them tolerable. Back in British Columbia the handling of the trailer was Greatly Improved , cornering with the truck as though it wasnt back there. The Shocks made the towing experience much better. I highly recommend installing the Roadmaster shock kit on your trailer, you will notice the difference in handling, towing comfort and improved towing safety.

Instructions where easy to follow and install went without incident. Only took the trailer for a short test drive after install so can't determine if trailer is riding better of rough roads.

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


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.

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.

Drastically improved the ride and comfort of towing my 31' 5th wheel RV trailer, as the trailer is much more stable and inputs far less sway, porpoising or bounce back to my truck while towing.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


I haven't installed them yet but first impression is that the parts are well built. The paper instructions and installation videos are very valuable. I recommend doing a little homework before starting the install. This will ensure you have all the parts and tools you need.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


I put this kit on my fifth wheel camper. The installation was was relatively simple. It made a noticeable difference in ride quality that I can feel even in the truck. When you hit a bump or a dip in the road the trailer doesn’t continue to bounce down the road. I’ve put over 5,000 miles it since the shocks were installed and I’m very happy with this upgrade. I would highly recommend it.

Product came with good instructions and installed exactly as advertised. Haven’t tested it on the road yet. I am going on a trip from Texas to New Mexico. The roads are terrible. Hope this makes the trip easier.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


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. Tow vehicle 2016 RAM 3500 CAB CHASSIS 4×4 CUMMINS 6.7 DSL Bradfofd built Aluminum 4 box bed.

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


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.

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

Continues to perform very well.

Installation was difficult. I had to release the spring shackles to drive the screws, but the chaos in the trailer appears to be reduced

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


The system was installed on a 35', 10.5K lbs (GVW), bumper pull travel trailer. It tows fine and the bouncing has improved, but not as much as I had anticipated. Your advertisement indicated the ride was greatly improved but I find things still falling over/bouncing around. I would suggest the system improves the trailer handling as the axle placement, connect point, road condition etc also effect the trailer handling...




by:

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension


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
