Engine Rocker Arm Adjusting Nut

Product Overview

*Rocker Arm Adjusting Nuts*
Many of the popular engine families utilize a positive stop type of rocker arm attachment, which does not allow for any adjustment, and consequently there is no consideration for different cam sizes or other modifications to the engine block and heads. For that reason, COMP has designed a kit to convert this setup to a fully adjustable valve train.
• Tapered for extra strength in locking areas
• 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
• Stud girdle polylocks are precision ground for minimum runout

*Rocker Arm Studs*
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 that 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.
