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

This Multi-Layer Steel (MLS) head gasket is a versatile, high-performance sealing solution engineered for 1985-1998 Evolution Big Twin engines as well as 883cc, 1100cc, and 1200cc Sportster models. Constructed with a robust stainless steel core and a specialized FKM (Viton) rubber coating, this gasket is designed to handle the intense thermal expansion and high cylinder pressures characteristic of the Evolution powertrain. The stainless steel layers provide the structural tension required for a long-lasting seal, while the FKM coating ensures a precision micro-seal that resists oil, heat, and combustion gases.

With a thickness of .040", this direct-fit gasket provides a reliable, standard-clearance seal that is ideal for routine maintenance, top-end rebuilds, or performance restorations. It offers a superior, leak-proof barrier that ensures peak mechanical efficiency and long-term durability for classic air-cooled Harley Davidson V-Twin engines.
