Since 1921, Cloyes has been the trusted leader in automotive timing systems. As a critical component of the engine’s timing system, the crankshaft sprockets work in unison with the timing chain, tensioners, guides and other sprockets, to ensure precise timing. Cloyes engine timing crankshaft sprockets are precision-tooled with exact tooth geometry and a perfectly matched bore, off-set and timing index for superior fit, reliability, and long-term performance. To ensure total timing system integrity, Cloyes recommends replacing the chain along with the tensioners, guides, and sprockets during service. Trusted by professionals for over a century & backed by an industry-leading warranty and technical support.

The variable valve timing (VVT) system allows the engine control module (ECM) to regulate the intake and exhaust valve phase angle providing the most optimal engine volumetric efficiency under all engine operating condition to control tailpipe emissions and engine efficiency. Variable valve timing is an emission control device and although there are various methods of operation, the typical device is regulated by oil control valves, actuator solenoids and camshaft phasers.
