Designed to maximize the efficiency of the stock hydraulic lifters in Evolution Big Twin and Sportster engines. This simple yet effective kit limits the travel of the hydraulic unit in high RPM situations, thereby, eliminating potential engine damage due to high RPM valve float. Under normal conditions they allow the lifter to operate as designed, resulting in low valve train noise and nominal maintenance. In effect, this provides a solid lifter for racing and hydraulic lifter for cruising. Sets of 4.
