ENGINE TIMING CRANKSHAFT SPROCKET

The Cloyes Gear S997 is an engine timing crankshaft sprocket designed to work in unison with the timing chain, tensioners, guides, and other sprockets to ensure precise engine timing. It features a precision-tooled tooth form, bore, off-set, and timing index for a superior fit, reliability, and long-term performance. Manufactured using premium materials and heat-treated for OE-level fit and function, this sprocket allows for smooth installation and reliable performance. Cloyes recommends replacing the entire timing system, including the chain, tensioners, guides, and sprockets, during service for total timing system integrity.
