Construction & Design

This cylinder head gasket is meticulously engineered using multiple layers of high-grade stainless steel, providing exceptional tensile strength and flexibility. The embossed outer layers are coated on both sides with Viton rubber, a synthetic fluoropolymer elastomer known for its outstanding heat resistance and chemical stability. This coating ensures a reliable seal even in harsh engine environments, preventing leaks caused by thermal expansion and contraction.

The gasket’s .080-inch thickness is optimized specifically for the 5.7L Gen-3 Hemi engine, balancing durability with the precise sealing requirements of the cylinder head and engine block interface. This design reduces the risk of gasket failure and helps maintain consistent compression and combustion chamber integrity.
