What is the primary benefit of the plasma moly coating?

The plasma moly coating on these rings is known for its excellent wear resistance. It helps reduce friction between the ring and the cylinder wall, which can lead to longer engine life and more consistent performance over time.

What does 'ductile radius face' mean for these piston rings?

Ductile iron provides a good balance of strength and resilience. The radius face design is a specific shape that helps the ring seat properly against the piston and the cylinder wall, promoting a better seal.

Can these rings be shipped to California?
