Firestone 556777 Ride-Rite Air Helper Spring Kit

The Firestone 556777 Ride-Rite Air Helper Spring Kit is a heavy-duty air suspension upgrade designed to restore proper ride height, reduce sag, and improve stability when towing or hauling heavy loads. Engineered by Firestone Industrial Products — a trusted name in air spring technology — this kit provides adjustable load support to complement your vehicle's existing suspension system.

Key Features:

• Adjustable air pressure allows you to fine-tune ride quality and load support on demand
• Helps eliminate squat, sway, and bottoming out under heavy payloads
• Durable rubber air springs built to withstand harsh road conditions and extreme temperatures
• Compatible with the vehicle's existing suspension — no permanent modifications required
• Includes all necessary hardware and brackets for a complete installation

Firestone Ride-Rite kits are a popular choice for trucks, SUVs, and vans that regularly tow trailers, haul cargo, or carry camper bodies. By adding air support to the rear suspension, drivers can maintain a level vehicle stance and improve overall handling confidence. Inflation and deflation can be managed manually or integrated with an onboard air compressor system.
