What is the purpose of the HP shim technology in this gasket?

The HP shim technology increases the clamping force around the combustion chamber. This helps to ensure a better seal, especially in open deck blocks, preventing leaks and maintaining engine integrity.

What is Viton coating and why is it used on this head gasket?

Viton is a high-performance synthetic rubber known for its excellent resistance to heat, oil, and other fluids. Coating the outer layers with Viton helps the gasket withstand the harsh conditions inside the engine and maintain a reliable seal.

Does this head gasket come with any installation hardware?

This product is for the head gasket only. It is recommended to check the manufacturer's instructions for any specific hardware requirements, such as head bolts, which are typically sold separately.

About this part

Product Details

This is the Cometic MLX head gasket for the GM LHU/LNF Gen-2 ECOTEC engine, specifically designed for an 88mm bore and a thickness of .048 inches. If you're working on the top end of your 2011-2013 Buick Regal or 2010 Chevrolet HHR equipped with this engine, a reliable head gasket is crucial for keeping your combustion chambers sealed and your engine running smoothly.
