Mahle Rings Buick 400 Eng 1978 Olds 400 Eng 1975 Pontiac 428 Eng 67-83 Plain Ring Set

This set includes Mahle OE plain piston rings, sized 0.060 inch undersize, designed for specific Buick, Oldsmobile, and Pontiac V8 engines. When you're rebuilding an engine, getting the right piston rings is crucial for proper sealing, oil control, and overall performance. These rings are built to meet the demands of OE requirements, focusing on reducing friction and minimizing oil consumption for a longer service life.

Mahle has a reputation for advanced piston ring technology, and this set is no different. They aim to reduce ring mass and friction, which can contribute to improved engine efficiency. This is a solid option if you're working on a classic Buick LeSabre, an Oldsmobile Delta 88, or a Pontiac Firebird from the late 60s through the late 70s, among other compatible vehicles. The 0.060 inch undersize means these are intended for use when the cylinder bores have been machined to that specific size.
