Peak Performance Racing Cam Sprockets were designed to precisely adjust cam timing efficiently and quickly. Adjustable cam sprockets are ideal when adjusting cam timing for optimum RPM range and peak power. Peak Performance sprockets are made from forged billet T6061 aluminum then machined on a CNC machine to produce sprockets that are unmatched in precision and craftsmanship.  In addition, our cam timing marks are a veneer style which allows engine tuners the accuracy needed for maximum horsepower gains. The timing marks are machined so that the markings will last the lifetime of the gear.
