Timing Chain - Z Series

The Timing Chain - Z Series by CLOYES is a precision-engineered single roller timing chain designed for GM and Ford engines that demand reliable valve synchronization. Built for mechanics and engine builders who understand that timing chain integrity directly impacts engine longevity, combustion efficiency, and overall drivability, this component serves as the critical link between your crankshaft and camshaft. Whether you're performing routine maintenance on high-mileage vehicles or assembling a performance build, a quality timing chain replacement prevents catastrophic engine damage and ensures consistent valve timing across all RPM ranges.

CLOYES timing chains are manufactured to OEM tolerances, featuring a single roller design that minimizes friction while maintaining precise pitch engagement with crankshaft and camshaft sprockets. The roller bearing surfaces reduce wear on the sprocket teeth and lower parasitic drag compared to older silent-chain designs, improving fuel efficiency and reducing engine noise during cold starts and high-load operation. At 0.64 lbs and compact dimensions of 4.65 x 1.75 x 4.75 inches, this chain is engineered for seamless fitment in factory engine bays while delivering the dimensional accuracy necessary for zero timing deviation—critical when upgrading to aftermarket cams or when original equipment has stretched beyond service limits.

This timing chain is ideal for DIY enthusiasts and professional technicians rebuilding Z-Series engines or addressing timing chain rattle—a common symptom in higher-mileage GM and Ford platforms. Installation pairs seamlessly with CLOYES sprocket sets and tensioner components for a complete timing system refresh. If you're hearing valve train noise, experiencing rough idle after startup, or simply performing preventive maintenance on an engine with over 80,000 miles, the Timing Chain - Z Series by CLOYES delivers factory-specification reliability at a competitive price point, ensuring your investment in engine performance or restoration stays on schedule.
