Mahle Rings Buick 301/350 L Eng 77-79 Checker 327/350 Eng 69-79 Chevy 302/327/351 Moly Ring Set

This Mahle OE Moly Ring Set is 0.040 inch undersize, meaning it's designed for engines that have been bored out slightly during a rebuild. Piston rings are critical for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. Mahle's moly coating on the top ring helps reduce friction and wear, which can lead to a longer service life for your engine components.

These rings are built to meet original equipment requirements, focusing on minimizing friction and oil consumption while ensuring a solid seal. This attention to detail helps maintain engine performance and efficiency. They are designed to fit a wide range of Buick, Chevrolet, and Cadillac engines from the late 70s through the mid-80s, including popular models like the Buick LeSabre, Chevrolet C10, and Cadillac DeVille.
