1984-2022 Evolution Big Twin / Sportster Rocker Base Gasket

This one-piece rocker base gasket provides a critical seal between the rocker housing and the cylinder head to prevent oil leaks. Manufactured from high-performance Foamet material, the gasket utilizes a coated metal core to provide superior thermal stability and structural integrity. The precision-engineered design ensures a reliable fit that maintains a consistent seal through repeated heat cycles and heavy engine use.

This part fits Evolution Big Twin models from 1984 to 1999 and Sportster models from 1986 to 2022.
