Cometic MLX Head Gasket for 4.500" Bore

Ensure peak engine performance and reliability for your high-performance motorcycle with the Cometic MLX Head Gasket. Specifically engineered for demanding applications, this Multi-Layer-Xtreme gasket provides an unyielding seal, crucial for engines utilizing turbos, high compression, or nitrous.

Description

The Cometic MLX Head Gasket represents the pinnacle of sealing technology for performance motorcycle engines. Crafted with meticulous precision in the USA, this advanced cylinder head gasket is an essential upgrade for any M-Eight application pushing the limits with power-adding modifications such as turbos, high compression ratios, or nitrous systems. The proprietary Multi-Layer-Xtreme (MLX) design features an innovative extra “stopper” fold-over layer, providing a critical torque-limiting surface that actively prevents yielding of the combustion seal, even under extreme conditions. Measuring a precise 4.500" bore and 0.052" thickness (1.32 mm), these gaskets are manufactured from premium fuel-resistant materials that are guaranteed not to creep, crack, or become brittle over time, ensuring long-term reliability. Advanced high-temperature coatings, combined with strategic embossments, create a superior micro seal for fluids against both the head and block surfaces. The robust Multi-Layer Steel (MLS) construction, featuring two outer Viton®-coated embossed spring steel layers and an inner steel layer, delivers exceptional support and durability, making this Cometic MLX Head Gasket a truly high-performance cylinder head gasket solution.
