Built for serious LS racers who push the limits. The Crower Severe-Duty Roller Lifters are designed to handle high-rpm abuse, aggressive cam profiles, and big-power nitrous or boosted applications.
Machined from premium heat-treated steel, these lifters feature a .903” body diameter with a tall body design (.300" over standard) to improve pushrod angle and valvetrain geometry. The vertical link bar setup keeps lifters locked in perfect alignment under extreme load, while high-pressure oiling and needle-bearing rollers ensure stability at high rpm.
Perfect for race or hardcore street/strip LS builds, these lifters deliver reliability where it counts — under full throttle.
