The COMP Cams Pro Magnum hydraulic flat lifter for Chevrolet SBC/BBC and specified V6 applications is designed to resist pumping up at higher RPMs. Built to maintain proper piston position and oil control, these lifters improve high‑RPM response and yield measurable gains over standard hydraulic lifters where an adjustable valve train is used and correct preload is applied.
