Mahle Rings GMC Pass 138 2.3L Quad 4 Eng 87-95 Moly Ring Set

This is a Mahle OE Moly Ring Set, part number 41555CP.030, designed for 2.3L Quad 4 engines from 1987-1995. These rings are a crucial part of your engine's rebuild, working to seal the combustion chamber and control oil flow. Mahle's design focuses on reducing friction, which can help improve efficiency and extend the life of your engine components.

The moly coating on these rings helps them seat quickly and reduces wear, especially during the critical break-in period. This means you can expect a more consistent seal and less oil consumption over time. Mahle engineers these rings with OE requirements in mind, aiming to minimize oil burning and provide a durable solution for your engine.

This set is a solid option for anyone rebuilding a 2.3L Quad 4 engine, fitting a range of vehicles like the Buick Skylark, Pontiac Grand Am, and Oldsmobile Achieva. Make sure to check the full fitment list to confirm compatibility with your specific application.
