Roadmaster 2500-70 Trailer Suspension Kit

Comfort Ride Slipper Springs attach to a central hanger that isolates each axle, so the two springs are no longer connected. Travel trailers and fifth wheels use traditional 'eye to eye' leaf springs which haven't changed much for 100 years. If you look at a horse buggy from the late 1800's, it has leaf springs very much like your trailer. This is why your trailer is constantly bouncing and swaying. When your front tire hits a pot hole, the front leaf spring reacts to it and telegraphs that energy through the equalizer to the back leaf spring. Then, when the back tire hits the same pothole, it happens all over again in reverse. You basically get twice the bounce with every bump. Comfort Ride uses Slipper Springs to break the connection between the front and rear axle. Both the front and rear springs will slide forward and backward in response to road conditions without transferring energy to the trailer. This movement absorbs and dissipates a significant amount of energy that would otherwise make your trailer ride rough, sway and tow poorly.
