Engine Timing Crankshaft Sprocket. (S621) by Cloyes
Along with the timing chain, tensioners, and guides, sprockets are an integral component within the timing system. Cloyes timing gears and sprockets are available as part of complete timing kits as well as for individual purchase and installation. Featuring helical tooth form for quiet operation, and precision-machined bore for true fit, Cloyes Timing Sprockets offer reliability and dependability for engine rebuilds and typical replacement jobs. Cloyes parts are CAD designed and manufactured using advanced materials. Each part is extensively tested for function and durability to ensure optimal performance. Cloyes recommends the chain tensioner(s), sprocket(s), and guide(s) also be replaced when the chain is replaced as these components play a vital role in supporting the chain and keeping it tight.
