Cometic MLX Head Gasket for Harley M-Eight

Engineered for extreme performance and unwavering reliability, the Cometic MLX Head Gasket is the ultimate upgrade for your Harley-Davidson M-Eight engine. This advanced Multi-Layer-Xtreme (MLX) gasket provides a superior seal, crucial for high-compression, turbocharged, or nitrous-assisted applications, ensuring your powerplant performs flawlessly under intense conditions.

Description

The Cometic MLX Head Gasket is meticulously designed to meet the rigorous demands of modified M-Eight engines. Utilizing cutting-edge Multi-Layer Steel (MLS) technology, this gasket features two outer Viton®-coated embossed spring steel layers that effectively create a micro seal for fluids against both the cylinder head and block surfaces. An inner steel layer provides additional structural support, contributing to the gasket's exceptional durability. The standout innovation is the MLX Gasket's extra “stopper” fold-over layer, which acts as a torque-limiting surface. This critical feature actively prevents yielding of the combustion seal, safeguarding your engine from potential damage during high-stress operation. With a precise bore size of 4.310" and a thickness of 0.036" (0.91 mm), these performance cylinder head gaskets are manufactured from premium fuel-resistant materials that resist creeping, cracking, and becoming brittle, ensuring long-term reliability. Proprietary high-temperature coatings further enhance their resilience, making them an essential component for any high compression engine gasket requirement. Proudly made in the USA, Cometic delivers uncompromising quality for serious riders.
