PRW Rocker Arm Studs

PRW rocker arm studs are premium engine fasteners, made from strong, heat-treated 4135 chromoly steel with rolled threads. They're designed to securely hold rocker arms in place, handling the extreme forces in race and high performance engines for reliable valvetrain operation. The studs are crucial for securing the rocker arms that open and close engine valves, often paired with poly locks and used in upgraded systems for better durability and performance than stock parts.
