Cometic GM LHU/LNF Gen-2 ECOTEC .040in MLX Cylinder Head Gasket - 88mm Bore

This is a Cometic MLX cylinder head gasket specifically for the GM LHU/LNF Gen-2 ECOTEC engine, designed with an 88mm bore and a .040 inch thickness. It's built to handle the demands of engines like those found in your 2011-2013 Buick Regal or 2010 Chevrolet HHR. A properly sealing head gasket is crucial for keeping your engine's combustion chambers isolated, preventing coolant and oil from mixing and maintaining compression.

The HP shim technology built into this gasket is a notable feature. It works by increasing the clamping force around the combustion chamber, which helps to create a stronger seal, especially important for open deck block designs. The outer layers of the gasket are embossed and coated with Viton, a material known for its resistance to heat and fluids, further enhancing its ability to seal effectively under pressure and temperature.
