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

This set of Mahle Moly Piston Rings is 0.020 inches undersize, designed to fit 2.3L Quad 4 engines found in a range of vehicles from 1987 to 1995, including models like the Pontiac Grand Am, Buick Skylark, and Chevrolet Cavalier. These rings are built to meet original equipment requirements, focusing on reducing friction and minimizing oil consumption for a longer service life. The moly coating on these rings helps them seat quickly and reduces wear on both the rings and the cylinder walls, contributing to improved engine performance and efficiency.

Mahle's approach to piston ring technology aims to lower friction and ring mass, which directly impacts how efficiently your engine runs. By minimizing oil consumption, these rings help keep your engine cleaner and reduce the need for frequent top-offs. This set is a solid option when you're rebuilding or refreshing the top end of your engine, ensuring reliable operation and a good seal between the piston and cylinder wall.
