Description

The Cometic MLX Head Gasket is a premium choice for Harley-Davidson M-Eight engines, especially those running a turbo, high compression, nitrous, or other power-adding modifications. This advanced Multi-Layer-Xtreme gasket features an innovative “stopper” fold-over layer, providing a crucial torque-limiting surface that effectively prevents yielding of the combustion seal. Manufactured from robust, fuel-resistant materials, these gaskets are designed to withstand high temperatures and pressures without creeping, cracking, or becoming brittle over time. With a precise 4.310" bore size and a thickness of 1.02 mm (0.040"), these MLS (Multi-Layer Steel) gaskets incorporate two outer Viton®-coated embossed spring steel layers, along with an inner steel layer for enhanced structural support. Proprietary high-temperature coatings and embossments create a micro-seal for fluids, ensuring optimal sealing between the head and block surfaces. Proudly made in the USA, Cometic MLX Head Gaskets offer unmatched quality and peace of mind for serious riders and builders.
