Construction & Design

This head gasket features a sophisticated multi-layer steel design composed of several embossed stainless steel layers that provide exceptional strength, flexibility, and sealing capability. The outer layers are coated on both sides with Viton, a high-performance fluoroelastomer rubber known for its excellent heat resistance and sealing properties. This ensures a tight seal against combustion pressures and prevents leaks even during extreme thermal cycling.

The center shim layer is made of uncoated stainless steel, allowing for precise thickness control to meet specific engine requirements. This combination of materials enables the gasket to maintain sealing integrity despite the expansion and contraction of engine components during operation, making it ideal for both stock and high-performance applications.
