The PSR Cam Chain Tensioner, part number 03-02008-29, is a precision replacement for the factory automatic or hydraulic cam chain tensioner used on select Honda CRF models. CNC machined from billet aluminum, this tensioner is designed to provide consistent cam chain control and dependable performance in demanding off-road and motocross applications.
By replacing the original automatic or hydraulic tensioner, the PSR 03-02008-29 helps address timing chain rattling and out-of-time conditions that can occur when the factory component fails. Its manually controlled design also helps prevent excessive timing chain tension associated with hydraulic tensioner operation, reducing the potential for premature engine wear when properly installed and adjusted.

Verify your motorcycle model and year before ordering, and follow the manufacturer’s installation and adjustment procedures for proper cam chain tension.
