This component synchronises your crankshaft with the camshafts to maintain precise valve timing. It runs through the cylinder and head, connecting the lower end to the top-end assembly. Over time, heat and high-RPM stress cause the pins and plates to wear, leading to chain stretch. A stretched chain compromises timing accuracy and risks catastrophic piston-to-valve contact. Replace this part during every major top-end rebuild or when your tensioner reaches its limit. Ensure your timing marks are perfectly aligned before rotating the engine manually. This is a direct-fit component designed to meet or exceed OEM specifications for your specific fitment.
