Using the heaviest duty brackets on the market Hellwig air helper spring kits are tough to beat. Designed to give you the benefit of better handling and control under heavily loaded conditions. These air helper springs are installed between the frame of GMC Truck and the suspension, providing load support through the use of air pressure. Heavy duty brackets, higher test pressure and a longer stroke make Hellwig air helper springs the superior choice.
1. Note: Never load vehicle beyond the manufacturer's maximum gross vehicle weight rating.
2. Fully compatible with Air Lift and Firestone compressor systems.
