Mahle Rings CHR 340 68-73 GMC 400 67-69 Moly Ring Set

If you're rebuilding the engine in a classic muscle car, Mahle OE Moly Ring Set CHR 340 is a solid choice. This set is designed for a range of V8 engines found in popular vehicles like the Dodge Challenger, Plymouth Barracuda, and Buick Gran Sport from the late 60s and early 70s. These piston rings are built to meet original equipment requirements, focusing on minimizing friction and oil consumption while aiming for a longer service life.

Mahle uses advanced moly coating on these rings. This isn't just for looks; the moly helps reduce friction between the piston ring and cylinder wall. Less friction means the engine can run a bit more efficiently and potentially last longer. They're well-made to help ensure a good seal for optimal compression and to keep oil where it belongs, in the crankcase, not burning in the combustion chamber.

This set is specifically sized at 0.030 inches undersize. Always double-check your cylinder bore measurements before ordering to ensure you get the correct size for your rebuild. Remember, these rings are not CARB approved and cannot be shipped to California.
