What is the primary function of these piston rings?

These piston rings create a seal between the piston and the cylinder wall. This seal is critical for maintaining combustion pressure, preventing oil from entering the combustion chamber, and transferring heat from the piston to the cylinder wall.

Why is the top ring size (1.5mm) important?

The top ring is the primary seal against combustion pressure. A 1.5mm top ring is a common size that helps ensure a strong seal, contributing to efficient engine performance and power delivery when properly installed.

Are these rings suitable for all engine builds?

This set is made from premium steel and is designed for engine rebuilds where durability and performance are important. However, it is not CARB approved and cannot be shipped to California. Always confirm compatibility with your specific engine build requirements.
