Description

Timing chain stretch is one of the most overlooked threats to engine reliability, leading to valve timing drift, reduced performance, and catastrophic engine failure if left unchecked. The Cloyes 9-130 is a double roller timing chain engineered to eliminate slop and maintain precise valve timing under sustained high-RPM operation. Whether you’re running a stock rebuild or a modified Small Block, this is the kind of foundational upgrade that separates bulletproof engines from ticking time bombs.
