Enginetech timing gear sets are precision-matched replacement components engineered to restore correct camshaft-to-crankshaft timing for engines that use gear-drive or direct-mesh timing systems. Built on over 40 years of engine rebuilding expertise, each set is designed around the specific engine family it serves - gear geometry, material selection, and center distance are matched to the original equipment specifications to ensure accurate valve timing and long service life. Proper gear condition is critical to preventing timing deviation, valve train noise, and accelerated camshaft wear. Enginetech documents every set with clear application-specific notes so you know exactly what cam gear material and configuration you are receiving before the engine is on the stand. Always verify fitment by year, make, model, VIN code, and engine displacement before ordering - multiple gear configurations often exist for the same vehicle nameplate.
