Product Description

The Firestone 2622 Ride-Rite Rear Air Helper Spring Kit is engineered to add adjustable pneumatic support to the rear suspension of **2008-2026 Ford E-450 Super Duty cab & chassis and Class C motorhome/cutaway models**. Designed to mount between the vehicle's frame and suspension, the double-convoluted air springs allow you to fine-tune air pressure - typically from about 5 to 100 PSI - to help keep the vehicle level when carrying heavy loads or towing. This helps improve ride comfort, steering control, and brake effectiveness under varying payload conditions.

With individual inflation valves, you can make side-to-side or front-to-rear adjustments to maintain level stance even with uneven loads. The kit includes all necessary components including air helper springs, heavy-duty mounting brackets, air lines, manual inflation valves, and hardware for installation. On most compatible chassis cab and cutaway models, installation uses factory holes without drilling and typically takes about **1-2 hours** with basic tools. This Ride-Rite system helps reduce suspension fatigue, prevent bottoming out, and maintain proper ride height and handling while towing or hauling heavy cargo.
