Mahle Rings Chevy Truck 366 6.0L Eng 66-87 GMC 366 6.0L Eng 69-87 Moly Ring Set

This is a Mahle OE Moly Piston Ring Set, part number 41130CP.030, designed for 366 cubic inch 6.0L engines found in a range of Chevrolet and GMC trucks from the 1960s through the late 1990s. These rings are crucial for maintaining proper compression, controlling oil consumption, and ensuring the longevity of your engine rebuild.

Mahle OE rings are built to meet the demanding requirements of original equipment manufacturers. They focus on reducing friction between the piston and cylinder wall, which helps minimize engine oil consumption and can contribute to a longer service life for your engine components. The moly coating on these rings helps with initial seating and provides a durable surface for consistent performance.

This set is a solid option if you're rebuilding the top end of your Chevrolet or GMC truck engine. It's important to note that these rings are 0.030 inch undersize, so ensure this is the correct size for your cylinder bore measurements during your rebuild.
