Construction & Design

This head gasket features a sophisticated multi-layer steel design that combines multiple embossed stainless steel layers for enhanced strength, flexibility, and durability. The outer layers are coated on both sides with Viton, a high-performance fluoroelastomer rubber known for its exceptional heat resistance and durability in harsh sealing environments. The center shim layer is uncoated stainless steel, allowing for precise thickness control to meet specific engine requirements.

The gasket’s design accommodates the differing expansion rates of aluminum cylinder heads and cast iron or aluminum engine blocks, preventing leaks caused by thermal cycling and mechanical stress. Its corrosion-resistant materials ensure long-lasting reliability even under the high-temperature and high-pressure conditions typical of modern 5.7L HEMI engines.
