Smart Maintenance for Your Twin Cam
Replacing your outer cam chain is a key part of comprehensive engine maintenance or an essential step during a cam chest upgrade. It's imperative to regularly inspect your cam chains for any signs of wear, stretching, or noise. While this cam chain is a standalone replacement, we recommend checking the condition of your cam chain tensioners simultaneously. Both inner and outer tensioners experience different wear patterns, and addressing them together ensures your entire cam chest system is operating at its best.
