1985-1998 Harley Davidson Big Twin Evolution Head Gasket - Teflon

This specialized head gasket is precision-engineered for the 1985-1998 Evolution Big Twin engine, featuring a high-grade Teflon (PTFE) construction designed for superior sealing and chemical resistance. The Teflon material acts as a premium, low-friction surface that allows for the necessary thermal expansion and "scrubbing" movement between the cylinder head and the block without compromising the integrity of the seal.

Designed to withstand the intense heat cycles of the air-cooled Evolution powertrain, this gasket effectively fills microscopic surface irregularities to prevent combustion leaks and oil migration. As a direct-fit replacement for iconic models like the Fat Boy, Heritage Softail, and Electra Glide, it provides the durability and torque retention required to maintain peak engine compression and long-term mechanical reliability.
