Timing Chain - .005 Short

The Cloyes Timing Chain - .005 Short (MPN 9-130-5) is a precision-engineered double roller timing chain designed for Small Block Chevy and Small Block Ford engines seeking tighter valve timing tolerances and optimized engine geometry. This specialized chain compensates for wear patterns and manufacturing stack-up by delivering 0.005 inches of corrective length reduction, making it an essential component for builders working with high-performance or stroker applications where OEM chain stretch has accumulated or where port timing refinement demands exact specifications.

Manufactured by Cloyes—an industry leader in OEM and performance timing components—this double roller chain utilizes proven roller design to minimize friction and ensure consistent power transmission from crankshaft to camshaft. The 0.005-inch shorter profile addresses common issues in rebuilt or modified engines where original chain wear or custom camshaft timing curves require increased accuracy. The double roller construction provides superior load distribution compared to single roller designs, reducing wear rates and maintaining precise valve event timing across extended engine operation and high-RPM duty cycles.

Mechanics and engine builders targeting Small Block Chevy 262–400 cubic inch or Small Block Ford 200–351 cubic inch platforms will find this timing chain essential when diagnosing timing drift or building performance packages with aftermarket cam profiles. Proper installation requires removal of existing chain and sprocket assembly; verification of crankshaft and camshaft keyway alignment is critical before assembly. This product is sold individually and weighs 1.03 lbs, making it suitable for single-engine builds or replacement service work where OEM chain dimensions no longer guarantee optimal valve timing accuracy.
