Made from resistant high-quality material, the Koso chain tensioner could save your engine from expensive damage. Koso came up with this long lasting solution to replace the O.E.M. chain tensioner which has a tendency to wear prematurely.
- The arm is made with aluminum 6061, and the wheel is made with JIS SCM415 (=SAE 4115) alloy structure steel (chromium molybdenum steel).
- Sold as a kit.
Note: This is an aftermarket part built for racing purposes ONLY. Koso is not responsible for any damages caused to the parts, vehicle, or to yourself and others. Engine parts are not under warranty nor is collateral damage or cost of labor, in cases of malfunction.
