AEM Tru-Time Adjustable Cam Gear. Black. 5-Bolt. Mitsubishi 4G63 (23-831BK)

AEM TRU-TIME Adjustable Cam Gears increase horsepower and torque without having to change the camshaft(s) and are must-have items for engines that are milled; forced induction; high compression and/or utilizing aftermarket competition cams. Our gears enable users to match cam timing with their vehicles 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 as the hardest anodizing process on the market.
AEM TRU-TIME Adjustable Cam Gears are available in a multi-spoke; five-bolt design for most vehicles and our classic full-faced; three-bolt design for select applications. Five-bolt cam gears have an 8 in the suffix (23-8XX); and three-bolt cam gears have a 6 in the suffix (23-6XX).
