Collection: Lifters & Rocker Arms

Ensure precise valve actuation, reduce valvetrain friction, and maintain valvetrain stability with high-performance and OEM replacement lifters and rocker arms. Operating at the core of overhead valve (OHV) and overhead cam (OHC) engines, lifters (tappets) convert camshaft lobe profiles into vertical motion, while rocker arms multiply and translate that force to open and close intake and exhaust valves. Over time, high spring pressures, oil starvation, and elevated RPMs cause noisy lifter ticking, worn trunnion bearings, wiped cam lobes, lost valve lift, and sudden valvetrain failure.

Whether you're performing a routine top-end refresh on a daily driver, converting to a hydraulic or solid roller setup for high-RPM stability, or building a high-horsepower engine for drag racing, track days, heavy diesel towing, or off-road use, upgrading your valvetrain hardware maximizes airflow and reliability. Explore hydraulic roller lifters, solid roller lifters, flat tappet lifters, roller tip and full roller rocker arms, shaft-mount rocker systems, stud-mount rockers, trunnion upgrade kits, guide plates, rocker studs, and adjustment nuts across popular domestic, import, and diesel engine platforms.
