Replace your stock rocker arm studs with these COMP Cams rocker arm studs. The Magnum series studs work well in applications with moderate lifts and spring pressures. These studs have thin jam nuts for rocker clearance, rolled threads for maximum contact, and ground-flat tops to achieve and maintain accurate valve adjustments. The jam nuts are large in diameter to spread the load over larger areas. COMP Cams studs have generous radii and feature a black oxide finish.
