Replace your stock rocker arm studs with these COMP Cams rocker arm studs. When ultimate strength is required, as with high-rpm roller cam applications, Hi-Tech Race studs are just what you need. 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. All COMP Cams Hi-Tech studs have generous radii and feature a black oxide finish.
