What is HP shim technology?

HP shim technology is a design feature that increases the clamping force around the combustion chamber. This helps to create a stronger seal, especially in open deck engine blocks, reducing the chance of leaks.

What is Viton coating?

Viton is a high-performance synthetic rubber known for its excellent resistance to heat, oil, and other chemicals. Coating the gasket with Viton helps it maintain a strong seal under tough engine conditions.
