Hellwig Air Bag Helper Spring Kits offer greatly improved handling and control under heavily loaded conditions. The air helper springs are installed between the frame of your Chevy/GMC 1 2wd & 4wd Pickup Truck and the suspension, providing load support through the use of compressed air. Each Hellwig Air Kit is specifically designed to maximize the safe load carrying capacity of your Chevy Truck up to it's Gross Vehicle Weight rating. Heavy duty brackets, higher test pressure, and a longer stroke make Hellwig air helper springs the superior choice to competitors.
NOTE: Never load vehicle beyond the manufacturer's maximum gross vehicle weight rating.
