Cloyes has built automotive timing systems since 1921. This inverted-tooth chain uses pre-stressed, heat-treated steel construction for strength and wear resistance, with precision pitch control for an optimal chain-to-sprocket fit that reduces noise, minimizes fatigue, and helps maintain accurate valve timing.
- Chain build: Inverted Tooth type, 122 links, 0.38 in (9.53 mm) pitch, 22.63 in (574.68 mm) long, 0.55 in (13.97 mm) wide, single row.
- Steel construction: Pre-stressed and heat-treated steel for durability under high-stress operation.

Signs the timing chain may need replacing include a rattle or slap noise at startup or timing-related trouble codes; diagnose the cause before replacing. The listed applications call for two chains per engine, so order accordingly (sold as stated; minimum order quantity 1). Cloyes recommends replacing the chain along with the tensioners, guides, and sprockets for total timing-system integrity. Cataloged in the center position. Country of origin: China. Manufacturer part number C391.
