Replace your stock rocker arm studs with these Comp Cams rocker arm studs. Choose from High Energy, Magnum, and Hi-Tech race series studs to suit your vehicle's needs. The High Energy and Magnum series studs work well in applications with moderate lifts and spring pressures. They are available in 3/8 in. and 7/16 in. sizes. When ultimate strength is required, as with high-rpm roller cam applications, the 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 studs have generous radii and feature a black oxide finish.
