Firestone 8074 Ride-Rite Air Helper Spring Kit

The Firestone Ride-Rite 8074 is a heavy-duty air helper spring kit engineered to supplement your vehicle's existing leaf-spring suspension. Designed and manufactured by Firestone Industrial Products — the pioneers of automotive air spring technology since 1938 — this kit delivers adjustable load support to improve stability, ride quality, and safe load-carrying capacity.

Key Features:

• Heavy-duty convoluted air springs mount between the vehicle frame and suspension
• Individual inflation valves allow independent side-to-side or front-to-rear pressure adjustment for off-center loads
• Reduces inter-leaf friction for a smoother, more controlled ride under load
• Helps prevent suspension sag, bottoming out, and headlight misalignment when hauling or towing
• Compatible with standard Ride-Rite air control accessories for on-demand inflation management
• Complete kit includes air springs, mounting brackets, hardware, air line tubing, and inflation valves
• Typical installation time of 1–2 hours; most applications require no drilling

The Firestone Ride-Rite 8074 air helper spring kit is ideal for trucks, SUVs, vans, and RVs equipped with leaf-spring suspensions that regularly carry heavy payloads or tow trailers. By adding adjustable air pressure support alongside the factory suspension, the Ride-Rite system maximizes braking effectiveness and keeps your vehicle level under varying load conditions.
