Stop Tech GM Caliper 2.5 Piston
The first adjustable polyurethane bump stop of its kind. This bump stop stands up well to contaminants that destroy rubber and has been engineered to give longer lasting performance. Simply add a packer in the inner rings to increase rating to meet your desired load. Conventional springs still carry the load of the vehicle’s static weight, but at speed with downforce in the mix, the bump stops take over most of the work.
