Pushrod Guide Plates
PUSHROD GUIDE PLATES
Pushrod guide plates reduce the unwanted sideways motion of the pushrod under load. This keeps the rocker arm stabilized, making the valve operation much smoother and more efficient. Milodon guide plates hold the pushrods in precise and correct alignment for proper valvetrain operation without breakage at high loads and high RPM. They are heat treated chrome moly steel to reduce wear and are a must for any engine.
