Firestone 8040 Ride-Rite Air Helper Spring Kit

The Firestone Ride-Rite 8040 is a bolt-on air helper spring kit designed to improve load support, leveling, and ride quality when towing or hauling heavy loads. By supplementing the factory rear suspension, these air springs help eliminate sag, bottoming out, and trailer sway — keeping your vehicle level and in control under demanding conditions.

Key Features:

• Bolt-on installation — no cutting, drilling, or welding required in most applications
• Adjustable air pressure from 5 to 100 PSI to match your load requirements
• Double-bellows air spring design for maximum travel and durability
• Compatible with factory suspension — does not affect ride quality when unloaded at low PSI
• Durable rubber and reinforced-cord construction for long service life
• Includes all necessary hardware and instructions for installation

The Firestone Ride-Rite system is an ideal solution for drivers who regularly haul heavy payloads or tow trailers and need reliable, adjustable support beyond what the stock suspension provides. The kit can be paired with Firestone's Wireless Air Command or manual inflation systems for convenient on-the-fly pressure adjustments.
