9101-8-Z Cyl base nut kit

Securing your cylinders properly is critical for preventing base gasket leaks on your Shovelhead. This Colony cylinder base nut kit is designed for 1979 to 1984 1340cc Big Twin models. Unlike the earlier styles, these nuts feature a hex flanged design which helps distribute the clamping force more evenly across the cylinder base. The zinc-plated finish offers excellent protection against the elements while keeping your engine looking sharp. Whether you are performing a routine service or a full engine overhaul, using fresh, high-quality hardware is the best way to ensure your motor stays tight. This kit includes the necessary nuts to get your top end buttoned up correctly.
