Common questions

What gaskets are included in this top-end kit?

This is a comprehensive top-end gasket set for Sportster engines, designed for models with a metal rocker arm base. It includes all necessary gaskets for the cylinder heads and rocker boxes.

Is this a complete gasket set for the entire engine?

No, this is a top-end-only kit. For a full engine rebuild, you would need to purchase additional bottom-end gaskets and seals separately to cover the crankcase and other lower engine components.
