Arnott's new coil spring conversion kit was exclusively designed for GM Bravada/Envoy/Rainier/Trailblazer/Saab 9-7x (113" SWB) models. This suspension kit converts the rear air suspension to a reliable coil spring suspension system. This aftermarket kit features powder-coated, variable-rate coil springs. This conversion kit comes with instructions on disarming your factory air suspension system in order to turn off the warning lights. Note that the Trailblazer SS might be higher in the rear when you use this conversion kit.
