AEM Tru-Time Adjustable Camshaft Gears for Milled & Forced Induction Engines

AEM Tru-Time Adjustable Camshaft Gears for Milled & Forced Induction Engines Optimize power without replacing cams. AEM Tru-Time Adjustable Camshaft Gears let you precisely tune cam timing to match milling, forced induction, high-compression builds or aftermarket competition cams — unlocking additional horsepower and torque while preserving your existing camshaft(s). True 1° adjustment: Laser-etched, easy-to-read timing marks allow advancing or retarding cam timing in one-degree increments for accurate, repeatable setups. Durable, precision machined: Precision-cut gear teeth protect the belt contact surface from premature wear for long service life under extreme conditions. Industry-leading anodizing: AEM’s lab-tested hard anodizing on the gear teeth delivers superior surface hardness and corrosion resistance compared to standard finishes. Engineered for performance builds: Ideal for engines that are milled, boosted, high-compression, or running aftermarket competition cams where fine-tuned timing yields measurable gains. Whether dialing in cam timing for dyno tuning, compensating for head or deck modifications, or optimizing boost-era ignition maps, AEM Tru-Time gears provide the control and durability professional tuners and enthusiasts demand.
