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.
