What does the '.030' in the part number mean?

The '.030' indicates that this piston ring set is 0.030 inches undersize. This means it's intended for use with pistons and cylinders that have been machined to be 0.030 inches smaller than their original factory dimensions.

Are these rings suitable for a performance build?

These Mahle rings are built to OE specifications and are known for their advanced technology, reduced friction, and minimal oil consumption. While excellent for a rebuild or refresh, for extreme performance applications, it's always best to consult with a performance engine builder to ensure they meet your specific horsepower and stress requirements.

What is the benefit of a moly coating on piston rings?

The moly (molybdenum) coating on these piston rings helps to reduce friction between the ring and the cylinder wall. This can lead to improved engine efficiency, less wear over time, and better oil control.
