Bumps, dips, and uneven pavement don’t have to jolt your trailer. The Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers uses heavy-duty, nitrogen-charged shocks to absorb vibration and limit up-and-down movement. These shocks cut bouncing, chucking, and porpoising by up to 50%, bringing a calm, stable feel even over gravel or cobblestones. The result is a smoother, quieter ride where gear stays put inside and handling stays precise.
Traditional equalizers transfer shock between axles, causing axle roll-up and lost traction under braking. This system replaces that setup with fixed center hanger boxes that isolate each axle. That independent design prevents shock transfer and keeps all six tires gripping evenly, improving braking traction by as much as 70%. It means better control, shorter stopping distances, and a safer tow overall.
The included slipper leaf springs slide inside the hanger boxes on rollers rather than pivoting on a central bolt. Each spring’s movement translates into smooth front-to-back motion instead of harsh jolts. The rollers keep the spring ends from hopping, reducing noise and vibration while taking the edge off potholes and dips. This setup feels controlled and balanced, not choppy or loose.
Each of the six slipper leaf springs has a 3,500-lb capacity and is made from 4 leaves of 3/8" thick steel, measuring 27" long x 1-3/4" wide. The spring eyes come with Never Fail bushings pre-installed—constructed with molybdenum and graphite for durability that outlasts brass or nylon without needing grease. It’s a low-maintenance setup that stays quiet and strong mile after mile.
Designed for 3" diameter axles typically rated between 5,200 lbs and 7,000 lbs, this kit includes six slipper springs, four center hanger boxes, and six shocks. The parts bolt over existing hangers for a secure fit with minimal drilling. When installed, the suspension geometry stays true, and the trailer ride height remains unchanged—just smoother, steadier, and ready for long miles ahead.

Glad they are working well for you, Dillon! I don't think I have ever heard a bad review of this system as it just gets the job done! ^___^ What did you install it on?

Love the pics! Now that you got your ride quality under control. Where are you taking the RV this summer?

After a complete frame rebuild and reinforcement caused by weak factory suspension. There is no question the Roadmaster suspension is still the best upgrade we have done on our 5th wheel RV.

Really like the Roadmaster comfort ride suspension. It greatly reduces movement of products inside the 5th wheel while towing compared to the original CRE 3000, often on decent roads nothing moves at all, on rough roads still some movement but nothing like before. Strongly recommend

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.

That sounds like it was an awesome trip you went on, Terry! I'm happy that the handling is better so that longer trips are in a way, smooth sailing. Do you have an fun trips planned for this summer?
