Timing Chain - Z-Series

The Timing Chain - Z-Series from CLOYES is a double-roller timing chain engineered for small-block Chevy and small-block Ford engines. This component is essential for any engine rebuild, restoration, or high-mileage maintenance project where OEM-equivalent reliability is non-negotiable. Timing chains synchronize crankshaft and camshaft rotation, ensuring precise valve timing and combustion control—making chain quality critical to engine longevity and performance.

The double-roller design reduces friction and wear compared to single-roller configurations, distributing load across dual roller surfaces for smoother operation and extended service life. CLOYES has manufactured timing components for over a century, and this Z-Series chain reflects precision manufacturing standards that ensure consistent pitch, proper tensioning characteristics, and compatibility with OEM sprockets. The robust construction minimizes elongation over thousands of engine cycles, a common failure point in inferior aftermarket chains that leads to timing drift and potential engine damage.

Mechanics and engine builders specify the Timing Chain - Z-Series for comprehensive timing set upgrades on 262–400 cubic inch small-block Chevy platforms and comparable small-block Ford applications. Installation is straightforward when paired with matching timing set components—sprockets, gaskets, and covers—and requires no modifications to standard engine blocks or heads. At 1.03 lbs, this timing chain is compact and lightweight, making it suitable for both street and performance builds where durability and reliability trump compromise.
