Product Details

The Gates Accessory Belt Drive Kit line is built to simplify full-system serpentine service by replacing the belt and the wear components that drive it. On covered Toyota Camry, Toyota Highlander, and Lexus RX350 applications, servicing the belt alone can leave aged tensioning or pulley components in place, which can shorten belt life and affect front-end accessory performance. The 90K-39424A is engineered as a matched service kit for those applications, with components selected for the listed fitments and installation guidance included for accurate repair.

This part cross-references Gates 90K-39424A for the same application.
