Mahle Rings GM 3.7L LLR I5 Eng 2010 - Up Moly Ring Set

If you're rebuilding the engine in your 2007-2012 Chevrolet Colorado, GMC Canyon, Hummer H3, H3T, or Isuzu i-370, a fresh set of piston rings is essential. These Mahle Moly Piston Ring Sets are designed for the 3.7L LLR I5 engine, playing a critical role in sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. Getting this right is key to a healthy, long-lasting engine rebuild.

Mahle OE rings are built to meet the demanding requirements of original equipment manufacturers. They focus on reducing friction within the cylinder, which can lead to improved efficiency and a longer service life for your engine. The moly coating on these rings helps with initial break-in and can further minimize wear and oil consumption over time. This set is specifically sized at 0.040 inch undersize, which is important to note if you are re-boring your cylinders to a specific size.
