Cam Chains / M8 - Twin Cam - '06 Dyna

Heat treated S&S cam chains, 11 percent stronger than the factory chain, as a direct drop in replacement on Harley-Davidson Milwaukee-Eight and Twin Cam engines.

A stretched cam chain moves timing quietly and gradually, which is why it usually gets found during other work rather than diagnosed on its own. S&S manufactures these to reduce that stretch, with heat treated links and components that extend service life and hold timing through the kind of torque a built motor makes. They install exactly where the factory chain came out.

Features of the S&S Cam Chains

• Engineered to handle high torque and high horsepower performance builds
• Precision manufactured to reduce valvetrain stretch and lengthen maintenance intervals
• 11 percent stronger than standard factory OEM chains to minimize timing stretch
• Heat treated links and components significantly extend service life

S&S Cam Chain Fitment

• Primary outer chain, 22 links, replaces OEM #25675-06. Fits '17-'25 Harley-Davidson Milwaukee-Eight, '07-'17 Twin Cam and the '06 Dyna
• Secondary inner chain, 16 links, replaces OEM #25683-06. Fits '07-'17 Twin Cam and the '06 Dyna
