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 a black oxide finish.

• Designed for ultimate strength and locking force

• High Energy™ and Magnum polylocks are best for moderate lift and spring pressure applications

• Hi-Tech™ Polylocks work well in all high end race applications

• The stud girdle polylocks are precision ground for minimum runout and tapered for extra strength in the locking area
