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.


Gas Shocks Absorb Road Vibration

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.


Roadmaster Comfort Ride Shock Absorber

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.


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. 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.


Rigorous Testing Standards

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

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.

  • How To Make Hauling A 43ft Fifth Wheel More Comfortable With A 2019 GMC Sierra 2500 Duramax
    That is a pretty big camper. You have done most of what you can do on your 2019 GMC Sierra 2500 SRW Duramax. The anti sway bar on the truck is only going to really benefit you if you are hauling a bunch of weight in the bed of the truck which is not the same as hauling a fifth wheel on a hitch.
