What does the moly coating on these piston rings do?

The moly coating on these Mahle piston rings helps them seat properly against the cylinder walls. It also reduces friction and wear, which contributes to a longer service life for both the rings and the cylinder bores.

Are these rings a standard size?

No, this is a 0.030 inch undersize piston ring set. This means the cylinders in your engine should be bored to match this specific size for proper fitment and sealing.

What vehicles does this ring set fit?

This set fits a wide variety of vehicles, primarily those with 5.7L engines from manufacturers like Buick, Cadillac, Chevrolet, and GMC, spanning model years from 1989 to 2002.
