Firestone Coil-Rite Air Helper

The Firestone Coil-Rite Air Helper spring kit is an air spring system for vehicles with coil spring suspension. Installed inside the coil spring, it adds adjustable load support. Many owners call it an air helper spring, air assist spring, or air bag helper kit. It helps vehicles that tow, haul, or carry extra weight keep a level stance and a more controlled ride.

Key Features:

• Air springs fit inside the factory coil spring to add load-carrying support
• Adjustable air pressure lets you tune support to match the load
• Helps reduce rear sag and keep the vehicle level when towing or hauling
• Works alongside the original springs, so the factory suspension stays in place
• Durable construction from Firestone, a long-established maker of air spring products
• Kits are designed for bolt-on installation and include the hardware and air line components that Firestone specifies for each kit

Firestone Coil-Rite kits give added load support without replacing the factory suspension. This makes them a practical choice for trucks, SUVs, and other vehicles that carry heavy or varying loads.
