AEM Tru-Time Adjustable Cam Gears are used by top racing teams across the country and are a must for engines that are milled, forced induction, high compression and/or utilizing aftermarket competition cams. AEM gears enable users to match cam timing with their vehicle's tuning state by advancing or retarding the cam profile in one-degree increments via true laser-etched markings. Precision-cut gear teeth ensure no premature wearing of the belt surface and AEM's anodizing on the gear teeth is lab-test-proven to be the hardest anodizing process on the market.
