Product Description

The **Ford Performance M-6266-M50B Boss 302 Timing Chain Tensioner Kit** is a performance-oriented upgrade designed for Ford's 5.0L Coyote V8 engines used in Mustang and F-150 applications. These tensioners were developed as part of the Boss 302 and Cobra Jet engine programs to provide stronger, more durable tensioning capability in high RPM environments where stock tensioners may struggle. The kit replaces both primary and secondary timing chain tensioners and includes all necessary mounting hardware for a complete installation.

Intended for enthusiasts and racers alike, these tensioners help maintain proper chain tension under sustained high power or high RPM use, improving reliability and reducing the risk of timing chain related issues in performance builds. Installation typically involves replacing existing timing chain tensioners with the Ford Performance units, and in some cases requires using specific tensioner arms to accommodate the updated tensioner design. This upgrade is ideal for street performance and track-focused builds where engine durability and precision timing are essential.
