Maintaining proper tension on your timing chain is essential for the smooth and accurate operation of your camshafts.

A loose or slack chain—often due to a failing tensioner—can cause timing misalignment, which may result in serious engine damage.

The tensioner keeps the timing chains firmly engaged with the cam gears and crankshaft, ensuring precise timing and reducing chain noise.

This is the latest genuine revised part, designed to address issues found in earlier versions, which were known to fail.
