This Hellwig EZ-990 Helper Spring Kit gives your GMC Sierra 1500 the benefit of increased level load capacity (up to 2000 lbs.) Designed to stabilize, prevent body roll, and maintain level ride height, these Helper Springs will make hauling heavy loads much safer. Hellwig #986 Helper Springs install easily by mounting on top of existing rear leaf springs. These are a great upgrade for anyone wanting more control from their ride.
Will not fit on vehicles equipped with factory overloads unless the factory overloads are removed and discarded. Never load your GMC Sierra 1500 beyond the manufacturer's maximum gross vehicle weight rating.
