Construction & Design:

This head gasket features a robust multi-layer steel design, combining multiple embossed stainless steel layers to provide strength and flexibility. The outer layers are coated with Viton, a high-performance fluorocarbon elastomer known for its exceptional resistance to heat, oil, and chemicals, ensuring a reliable seal even in harsh engine environments. The embossed design enhances the gasket’s ability to conform to surface irregularities, preventing leaks and maintaining compression.

The center shim layer is made from uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This construction enables the gasket to accommodate the differential expansion rates between aluminum heads and cast iron or aluminum blocks, reducing the risk of gasket failure due to shearing forces.
