Firestone 8039 Ride-Rite Air Helper Spring Kit

The Firestone Ride-Rite 8039 is a heavy-duty air helper spring kit engineered to supplement your vehicle's existing leaf-spring suspension. Designed as part of Firestone's most popular and comprehensive air spring lineup, the Ride-Rite system installs between the vehicle's frame and suspension to provide adjustable load support through air pressure.

Key Features:

• Double-convoluted air spring design delivers maximum load support and a cushioned, comfortable ride
• Individual inflation valves allow independent side-to-side or front-to-rear air pressure adjustment to level the vehicle under uneven or off-center loads
• No-drill installation on most applications — utilizes existing factory mounting holes for a clean, straightforward fit
• Complete kit includes air springs, brackets, hardware, air line, and separate inflation valves — everything needed for installation
• Typical installation time of 1–2 hours for most applications
• Reduces inter-leaf friction and absorbs road shock, helping prevent leaf spring sag under constant load
• Helps maintain level headlight aim, promotes even tire wear, and supports more responsive braking and handling when loaded
• Commercial-grade steel plates with rolled crimp construction, precision engineered from millions of commercial vehicle miles

The Firestone Ride-Rite 8039 air helper spring kit is compatible with select light trucks, SUVs, motorhomes, and RVs equipped with leaf-spring rear suspensions. Optional Air-Rite air compressor accessories are available separately for automatic or remote inflation control.
