Firestone 14975 Ride-Rite Air Helper Spring Kit

The Firestone Ride-Rite 14975 is a rear air helper spring kit engineered to supplement your vehicle's existing suspension system, providing improved load-leveling, reduced sag, and a smoother, more controlled ride when towing or hauling heavy loads. Designed to fit inside or alongside the factory coil or leaf springs, this kit delivers adjustable air pressure support so you can dial in the right ride height and stiffness for any load condition.

Key Features:

• Adjustable Air Pressure: Inflate or deflate to match your specific load — typically adjustable between 5 and 100 PSI
• Load-Leveling Performance: Prevents rear-end sag when towing trailers, hauling cargo, or carrying heavy payloads
• OEM-Style Fit: Mounts using existing factory hardware and attachment points for a clean, professional installation
• Durable Construction: Heavy-duty air sleeve and hardware components built to withstand road vibration, heat, and harsh weather
• Improved Stability: Reduces body roll, porpoising, and sway for safer, more confident towing and hauling
• Complete Kit: Includes air springs, mounting hardware, air lines, inflation valves, and installation instructions

The Firestone Ride-Rite line is one of the most trusted names in aftermarket air suspension support, with a proven track record across light trucks, full-size pickups, vans, and SUVs. The Firestone 14975 installs without cutting or welding on most applications and is compatible with Firestone's Ride-Rite wireless and wired onboard air compressor systems for convenient in-cab inflation control.
