Product Details
These Mahle Moly piston rings are built to a 0.040 inch undersize, meaning they're ready to be installed in an engine block that has been bored out to match. Piston rings are critical for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. Mahle designs these rings with OE requirements in mind, focusing on reducing friction and minimizing oil use for a longer-lasting engine.
This set is designed for a wide range of Buick, Chevrolet, and Cadillac engines from the late 70s through the mid-80s, including popular models like the Buick Regal, Chevrolet C10, and Cadillac DeVille. The moly coating on the top ring helps reduce friction and improve wear resistance, contributing to a smoother running engine and better overall performance. They are a well-built option for rebuilding or refreshing your engine.
