This Ride-Rite air helper spring kit installs at the rear between the frame and axle of select Ford E-450 cab-chassis trucks and Class C motorhomes and cutaways. Adjustable air pressure lets you level the vehicle under heavy loads or when towing, which reduces sag, bottoming out and sway while improving stability and braking. The kit is a manual fill setup, so you inflate the air springs through valves just like a tire, and it can be upgraded later with an optional on-board compressor.
