Construction & Design

This head gasket features multiple embossed layers of stainless steel, providing exceptional strength and the ability to rebound under pressure. The outer layers are coated with Viton, a high-performance fluoroelastomer rubber known for its excellent heat resistance and durability in challenging sealing environments. The center shim layer is uncoated stainless steel, allowing for precise thickness customization to meet specific engine requirements.

The MLS design effectively manages the differential expansion between aluminum cylinder heads and cast iron or aluminum blocks, preventing leaks and gasket failure caused by shearing forces. This construction ensures a long-lasting seal that maintains engine compression and prevents coolant or oil leaks, even under high-stress operating conditions.
