1985-1998 Harley Davidson Big Twin & 1200cc Sportster Standard Bore Head Gasket - FKM Rubber MLS Steel

This Multi-Layer Steel (MLS) head gasket is a high-performance sealing solution designed for both 1985-1998 Evolution Big Twin and 1200cc Sportster engines. Engineered with a high-strength stainless steel core and finished with a specialized FKM (Viton) rubber coating, this gasket is built to withstand the extreme thermal cycles and cylinder pressures inherent in air-cooled V-Twin engines. The stainless steel layers provide the necessary structural tension for a high-integrity seal, while the FKM coating ensures a precision micro-seal that is highly resistant to oil, heat, and combustion gases.

Featuring a precision thickness of .030", this direct-fit gasket allows for optimized quench and mechanical efficiency, making it an excellent choice for performance-oriented builds and standard top-end maintenance alike. It provides a robust, leak-proof barrier that ensures long-term reliability for classic Evolution and Sportster powertrains.
