Product Details

These Mahle OE piston rings feature a deep groove design with moly coating, a choice that matters for reducing friction and wear. They are built to meet original equipment requirements, aiming to minimize engine oil consumption and extend service life. This set is designed for General Motors 151 CID (2.5L) 4-cylinder engines produced between 1982 and 1993.

Mahle's approach focuses on the latest piston ring technology to achieve a balance between performance and durability. The moly coating on these rings helps to create a solid seal against the cylinder wall while also providing a smoother surface for reduced friction. This can lead to improved engine efficiency and a longer lifespan for your engine components.

This ring set fits a wide range of vehicles, including popular models like the Buick Skylark, Chevrolet S10, and Pontiac Grand Am from the 1980s and early 90s. When rebuilding or refreshing your engine, choosing well-built piston rings like these is a key step toward ensuring proper compression and oil control.
