Heavy-duty Ride-Rites are the workhorse of Firestone's air helper spring line.

The double convoluted air springs offer maximum load support, as well as years of worry-free service. Ride-Rite air helper springs can be installed on most light trucks, motorhomes, RVs, SUVs, and vans. Ride-Rites are installed between the vehicle's frame and suspension, providing load support through the use of air pressure. Firestone is committed to providing premium air helper spring kits. Ride-Rite air helper springs have become synonymous with quality, durability, and customer support.

Each application is specifically designed to maximize the safe load-carrying capacity, stability, and ride quality of the vehicle. Ride-Rite air helper springs utilize a pair of convoluted air springs which can be adjusted for changing loads. These air springs are capable of 3,200 to 5,000 lbs of load leveling capacity. Ride-Rite air helper springs enhance the ride by reducing interleaf friction. Please remember that air springs do not increase a vehicle's load-carrying capacity.

Everything is included for a quick, easy installation. Brackets, air springs, hardware, air line, and separate valves for manual inflation. Optional air accessories are available for all applications. Average installation time is approximately 1-2 hours.

Features
  • Keep the vehicle level, improve steering control and braking effectiveness
  • Reduce tire wear and suspension bottom out
  • Individual inflation valves allow for adjustment side-to-side to level off-center loads
  • Keep leaf springs from permanent sagging under repeated or constant load, reducing long term suspension fatigue
  • Absorb road shock, providing ideal ride conditions for passengers and cargo, and increasing overall vehicle stability

    JEGS Easy Kits are designed by JEGS high performance racing professionals to help you get all the performance parts you need for your race car, hot rod or truck.
