Description

The Cometic MLX Head Gasket is engineered for GM LS Series V8 engines, specifically designed for a 4.040-inch bore. Constructed with Multi-Layer Steel (MLS), this gasket provides superior sealing capabilities for high-output applications. It features a compressed operating thickness of 0.051 inches and incorporates a Viton rubber coating on the outer layers for durability and optimal clamp load. Cometic's MLX head gaskets are known for their advanced design, which includes unique integrated "stopper" layers. This design ensures optimal combustion chamber sealing and improved clamp load around the cylinder, contributing to overall engine reliability and performance. The use of stainless steel embossed layers further enhances their robustness. This head gasket is made to order, with an estimated delivery time provided after order submission. It is crucial to verify fitment for your specific vehicle, as UroTuning does not list universal fitment. The gasket is compatible with a wide range of GM LS-powered vehicles from various manufacturers, including Chevrolet, Cadillac, Buick, and more, spanning many model years and submodels such as Avalanche, Camaro, Corvette, Silverado, and others listed in the fitment details.
