Construction & Design

This head gasket features a sophisticated multi-layer steel design, consisting of several embossed stainless steel layers. The outer layers are coated on both sides with Viton, a high-performance fluorocarbon elastomer known for its exceptional heat resistance and chemical stability. This coating ensures a reliable seal even under harsh thermal and mechanical stresses.

The center shim layer is made from uncoated stainless steel, allowing precise control over gasket thickness to meet specific engine requirements. The combination of these materials provides excellent rebound characteristics, corrosion resistance, and the ability to accommodate the differential expansion rates between aluminum heads and iron or aluminum blocks.
