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.
