Specs:
This Comfort Ride suspension upgrade system greatly improves your towing experience. It serves as an add-on for your leaf spring suspension, and it provides a notably smoother ride, reducing chucking, axle roll-up, and suspension rebound. This means that you'll experience improved handling, even over potholes and uneven pavement. And the contents of your trailer will stay in place during travel.
While traditional leaf springs support your trailer to prevent bottoming out, they don't necessarily provide a comfortable ride. Due to the rigidity of the steel construction, leaf springs do a poor job of absorbing shock and bounce and limiting sway.
Adding these shocks to your existing leaf spring suspension offers a better solution. Gas-powered springs inside of the 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. The result is a more comfortable towing experience.
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. However, 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 motion during both compression and rebound.
The Comfort Ride shock absorber 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 of the Comfort Ride system is fairly straightforward.
The included tie plates replace your existing U-bolt tie plates. 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 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

Installation was as shown on videos Directions were clear and all parts were included and well packaged. I need to move the gray water drain line with being all plastic was not a problem. I’ve only pulled the trailer about 5 miles since the installation I believe it’s made a large difference in the ride in the tow vehicle and the sway and handling of the trailer. The only negative I found is the shock bolts bolts are metric and the assembly bolts are SAE easy to confuse a half inch self locking nut with a 12 mm. Ruined 1/2 inch nut requiring a trip to the hardware store. A good half inch drive impact wrench is a huge labor saver and putting the 32 self tapping bolts into the trailer frame. 720830

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 received my Roadmaster shock absorber kit for my 5th wheel trailer, and installed it with no problems. It is exactly what I wanted. The parts fit like a glove. 597410

Review from a similar 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

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

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 Comfort Ride in Trailer Leaf Spring Suspension
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. 694448

This is a great product, it smothered out my fifth wheel nearly eliminating the chucking. 666608
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. 801724
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. 787053
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. 783109
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! 777008

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 775901

Exceeded my expectations in performance on not so great highways across the United States. Porpoise action of the 5th wheel almost entirely eliminated. I strongly recommend this product to anyone. 769518
Review from a similar Comfort Ride in Trailer Leaf Spring Suspension
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. 746005

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension
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. 728615
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 728150
Review from a similar Comfort Ride in Trailer Leaf Spring Suspension
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. 713280

Review from a similar Comfort Ride in Trailer Leaf Spring Suspension
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!!! 672641
