Mahle Rings Chevy Trk 292 4.8L Eng 63-89 GMC 292 4.8L Eng 63-89 M F Trac Moly Ring Set

If you're rebuilding the engine in your classic Chevy or GMC truck, these Mahle Moly Piston Rings are a solid choice. Designed for the 292 cubic inch, 4.8L inline-six engine found in trucks from 1963 through 1989, these rings are built to meet the demands of OE requirements. They play a crucial role in sealing the combustion chamber, controlling oil consumption, and reducing friction within the cylinder bore.

Mahle has engineered these rings to minimize friction, which helps improve overall engine efficiency and can contribute to a longer service life. The moly coating on these rings helps with initial seating and provides a durable surface that works well with cylinder walls. This set is specifically sized at 0.040 inches undersize, meaning it's intended for engines where the cylinders have been bored out to match this dimension during a rebuild.

This set fits a wide range of Chevrolet and GMC trucks, including popular models like the C10 Pickup, C20 Suburban, and K20. Ensure your engine's cylinders have been machined to the 0.040 inch undersize specification before installation.
