Construction & Design

This head gasket features a sophisticated multi-layer steel design composed of multiple embossed stainless steel layers. The outer layers are coated with Viton, a high-performance fluoroelastomer rubber known for its exceptional heat resistance and sealing properties. This coating ensures a tight, leak-proof seal under extreme operating conditions, maintaining engine integrity and preventing coolant or combustion gas leaks.

The center shim layer is uncoated stainless steel, allowing precise thickness calibration to meet the exact specifications of the 5.7L Hemi engine. The embossed outer layers provide a spring-like effect, enabling the gasket to maintain sealing pressure despite thermal expansion and contraction between the aluminum heads and block materials, ensuring long-term reliability.
