Mahle Rings GMC Pass 400 428 Engs 1975-79 Moly Ring Set

These Mahle OE Moly piston rings are built with a moly coating, which helps reduce friction and wear right from the start. They are designed to fit GMC 400 and 428 cubic inch engines from 1975 through 1979, and are suitable for a wide range of vehicles from that era, including models like the Pontiac Firebird and Oldsmobile Delta 88.

Mahle engineers these rings to meet original equipment requirements, focusing on minimizing oil consumption and extending the service life of your engine. The moly coating is a key feature that contributes to this, providing an improved surface for the cylinder wall and reducing the initial break-in period. This attention to detail means you can expect a well-built set of rings that perform reliably.

When rebuilding or refreshing your engine, choosing the right piston rings is crucial for overall performance and longevity. This set from Mahle OE offers a solid option for your GMC engine project.
