Mahle Rings GMC Trk 6.6L 403 CID Duramax Turbo Diesel 2011+ LGH / LML GNS Top Plain Ring Set

These Mahle OE top plain ring sets are built to meet the demanding requirements of modern diesel engines, specifically designed for GMC and Chevrolet trucks with the 6.6L Duramax Turbo Diesel (LGH/LML) from 2011 and up. They are engineered to minimize friction and reduce overall ring mass, which helps in minimizing engine oil consumption and contributes to a longer service life for your engine.

Mahle's approach focuses on advanced piston ring technology, aiming to improve efficiency and durability. By reducing friction, these rings help your engine run smoother and potentially improve fuel economy. The focus on minimizing oil consumption means less oil is burned during operation, keeping your exhaust cleaner and your oil levels more stable between changes. This set is a direct replacement for your original equipment rings, ensuring a proper fit and function when rebuilding or refreshing your engine.

This ring set is suitable for a range of Chevrolet and GMC trucks, including models like the Silverado 2500 HD, Sierra 2500 HD, and Express/Savana vans. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
