SKF Timing Chain Kits are intelligently designed and assembled in a way that all parts and components functionality will have a long operating life. The perfect stretch of the chain allows for different heavy loads and prevents unnecessary friction of the kit components and no slippage between the chain and sprocket teeth. The perfect assembly of a Timing Chain kit is critical. It is of high risk to improvise assembling different sources of components into an engine service repair. SKF kit solutions follow OE system recommendations for component replacement of the timing chain, including guides, chain tensioners and sprockets.
