What does the .030 in the part number mean?

The '.030' in the part number 42082CP.030 indicates that these piston rings are 0.030 inches undersize. This means they are intended for use in an engine cylinder that has been bored out by 0.030 inches during a rebuild.

What is the benefit of moly coating on piston rings?

Moly coating on piston rings improves lubrication between the ring and the cylinder wall. This reduces friction, which can lead to better engine efficiency and a longer service life for both the rings and the cylinder bore.

Are these rings compatible with all 6.2L GM engines?

This specific Mahle ring set is designed for GM 6.2L LS3 and L99 engines found in certain Cadillac, Chevrolet, and Pontiac models from 2007-2017. It's important to verify fitment for your exact vehicle and engine code before purchasing.
