Comp Cams® takes pride in having the finest rocker arm studs available on the market. The High Energy and Magnum series studs work well in applications with moderate lifts and spring pressures and are available in the popular
3/8" and 7/16" sizes. When ultimate strength is required as with high rpm roller cam applications, the Hi-Tech race stud is the answer. This stud has a thin jam nut for rocker clearance, rolled threads for maximum
contact, and a ground-flat top so accurate valve adjustment can be achieved and maintained. The diameter of the jam nut is larger in order to spread the load over a larger area. All Comp Cams® studs have generous radii and
have a black oxide finish.
Add to:
If you have ever installed a rocker stud into a cylinder head and watched it wobble as it screwed in, you knew from the beginning that the rocker geometry was going to be inconsistent all over the place. ARP® rocker studs are
concentric within .005 T.I.R. thread pitch to thread pitch. They run in straight and true. Lengths are exact—designed to provide positive seating every time. An extra-large radius base offers greater resistance to flex.
