COMP Cams® takes pride in having the finest rocker arm studs availableon the market. The High Energy™ and Magnum™ series studs workwell in applications with moderate lifts and spring pressures and areavailable in the popular 3/8 and 7/16 sizes. When ultimate strength isrequired as with high rpm roller cam applications, the Hi-Tech™ RaceStud is the answer. This stud has a thin jam nut for rocker clearance,rolled threads for maximum contact and a ground-flat top so accuratevalve adjustment can be achieved and maintained. The diameter of thejam nut is larger in order to spread the load over a larger area. All COMPCams® studs have generous radii and a black oxide finish.
