Air Lift SlamAir Air Helper Spring Kit - Lowered Chevrolet / GMC C1500 1988-1998

The Air Lift SlamAir kit restores load-carrying capacity and stops bottoming out on lowered Chevrolet and GMC C1500 trucks. The helper air springs supplement the leaf springs to give an adjustable spring rate for ride comfort, safety and variable loads, and fit most lowered trucks with a 5 to 6 inch drop including flipped-axle and notched-frame setups. Air adjustable from 5 to 100 PSI with ultra high-strength nylon-composite end caps.
