Construction & Design:

This cylinder head gasket features a sophisticated multi-layer steel design, composed of several embossed stainless steel layers. The outer layers are coated with Viton, a high-performance fluorocarbon elastomer known for its exceptional heat resistance and chemical durability. This coating enhances the gasket’s ability to maintain a tight seal under extreme thermal and mechanical stress.

The center shim layer is uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This layered construction provides the gasket with the flexibility to rebound and maintain sealing integrity despite the differential expansion rates between aluminum heads and cast iron or aluminum blocks.
