S&S Tappet Cuffs Lifter Guides for 2017+ M8 Models

Replace the factory plastic tappet guides in your 2017+ Harley-Davidson Milwaukee-Eight engine with S&S Tappet Cuffs. Factory guides can allow the tappets to twist under heavy stress; these billet aluminum cuffs capture the tappets while maintaining normal vertical movement to help keep them aligned in demanding high-lift and high-RPM applications.

Machined from billet aluminum with a hard-anodized black finish, S&S Tappet Cuffs are a simple valvetrain upgrade when installing a camshaft or replacing tappets. They provide a stronger, more stable alternative to the factory plastic guides.
