Firestone 13998 Ride-Rite Air Helper Spring Kit

The Firestone Ride-Rite 13998 is a rear air helper spring kit engineered to supplement your existing suspension system, improving load-carrying stability, ride comfort, and handling performance. Designed and manufactured in the United States, Ride-Rite air springs install between the vehicle's suspension and frame to provide adjustable pneumatic support that adapts to changing load conditions.

Key Features:

• Includes a pair of heavy-duty convoluted air springs engineered for durability in demanding conditions
• Individual inflation valves allow independent side-to-side pressure adjustment for off-center or uneven loads
• Reduces inter-leaf friction for a smoother, more controlled ride under load
• Helps prevent suspension sag, bottoming out, and frame-to-axle contact when hauling or towing
• Load leveling capacity of up to 5,000 lbs. per set
• Kit includes brackets, hardware, air line, and inflation valves for a complete installation
• Most Ride-Rite kits are no-drill designs; installation typically takes one to two hours
• Backed by Firestone's lifetime air spring warranty for the original purchaser

Firestone Ride-Rite air helper springs are a trusted choice for truck and SUV owners who regularly tow, haul, or carry heavy payloads. By supplementing the factory suspension with adjustable air pressure, the Ride-Rite 13998 kit helps maintain proper vehicle attitude, improves braking effectiveness, and reduces wear on suspension components — delivering a safer, more confident driving experience.
