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

The '.030' indicates that these piston rings are 0.030 inches undersize. This is a common size used when engine cylinders have been bored out during a rebuild to ensure a proper fit and seal.

Are these rings suitable for a standard engine rebuild?

Yes, these Mahle OE Moly Piston Rings are designed to meet original equipment specifications for friction reduction, oil control, and service life, making them a solid choice for engine rebuilding.

What is the benefit of moly coating on piston rings?

Moly coating on piston rings helps to reduce friction between the ring and the cylinder wall. It also aids in the initial break-in process and provides a more durable surface for extended engine life.
