Enginetech timing chain sets are precision-matched replacement kits engineered to meet or exceed OEM specifications for chain stretch tolerance, sprocket tooth geometry, and guide/tensioner clearances. Built on over 40 years of engine rebuilding expertise, each set is designed to restore the factory valve timing relationship critical to engine performance, emissions compliance, and longevity. Chains are manufactured to OEM link count and pitch specifications; sprockets (where included) are produced from the same material spec as original equipment. Tensioners and guides, where included, are matched to the specific engine family to ensure correct hydraulic preload and wear surface geometry. Enginetech documents every kit with clear application-specific notes so you know exactly what is and is not included before the engine is on the stand.
