C9758F EST motor gasket kit

This Cometic EST motor gasket kit is the definitive solution for a full engine overhaul on 1991 to 2003 Sportster XL1200 models. Sold as a set, it includes every gasket, seal, and o-ring required for a complete reassembly, including the primary gaskets. The kit features .040 inch thick Multi-Layer Steel head gaskets that eliminate the need for dowel pin o-rings, paired with .020 inch Single-Layer Steel base and rocker cover gaskets. These SLS gaskets are coated with high-temperature Viton rubber to prevent weeping or tearing over time. You also get high-flow exhaust gaskets and Viton valve seals with outer springs for a superior seal. It is the easiest way to ensure you have everything on the bench before you start the build.
