Maintaining proper primary chain tension is vital for smooth shifting and long component life.

It is a high-quality replacement for the original equipment and includes the necessary hardware to refresh your primary drive's tensioning system. This kit is sold as a kit and is a reliable choice for standard maintenance or during a primary rebuild. It is a direct replacement for OEM 540020, ensuring a perfect fit inside your primary housing.
