Keep the crankshaft and camshaft turning in step with the CLOYES timing chain 9-304, a high-performance 3/8-inch-pitch single roller chain designed to hold your engine's valve events in time. It fits many vehicles, among them the 1999-2015 GMC Sierra 1500 4.8L / 5.3L / 6.0L / 6.2L, 1999-2007 Chevrolet Silverado 1500 4.8L / 5.3L / 6.0L and 1999-2007 Chevrolet Silverado 2500 4.8L / 5.3L / 5.7L / 6.0L. See the Buyer's Guide tab for the full list.

A timing chain synchronizes the rotation of the crankshaft and camshaft(s) so each cylinder's valve events stay properly timed. Cloyes builds this engine timing chain as a TRUE roller replacement chain. Its links are heat treated and processed to maximize ultimate breaking strength while staying ductile for toughness.

  • True roller design: 3/8 in. (9.5 mm) pitch single roller chain with a 0.250 in. roller diameter and one row.
  • Pre-stressed: pre-stressed to increase fatigue life.
  • Precision pitch control: engineered and built for proper chain-to-sprocket tooth fitment.
  • Specifications: steel chain with 60 links and a width of 0.54 in. (13.79 mm). It has no timing marks and is cataloged for the center position.

Cloyes designs its parts with CAD and builds them from premium materials. Each part is tested and measured for function, fitment and durability. The listed applications use one chain. Cloyes recommends replacing the chain tensioner(s), sprocket(s) and guide(s) whenever the chain is replaced, because those components play a vital role in system stability and accurate timing.
