What is the purpose of the moly coating on these piston rings?

The moly coating on these Mahle piston rings helps to reduce friction between the ring and the cylinder wall. This can lead to improved engine efficiency, reduced oil consumption, and a longer lifespan for both the rings and the engine.

What does the '.040' in the part number mean?

The '.040' indicates that these piston rings are 0.040 inches undersize. This means they are designed for engines where the cylinders have been bored out by 0.040 inches during a rebuild to restore proper fit and compression.

Are these rings compatible with all Buick and Chevy engines?

This specific ring set is designed for a range of Buick and Chevrolet engines from the late 1950s to the mid-1970s, particularly those with specific displacements like the Buick 364 and Chevy 348, 396, 400, and 402 cubic inch engines. It's important to verify fitment for your exact engine model and year.

Product Details

This is a Mahle Moly Piston Ring Set, part number 40141CP.040. You get a complete set of moly-coated piston rings designed to fit a wide range of Buick and Chevrolet engines from the late 1950s through the early 1970s, including popular models like the Buick LeSabre and Chevrolet Impala. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall.

Mahle's moly coating on these rings helps to reduce friction between the piston ring and cylinder wall. This not only contributes to a longer service life for the rings and the engine but also helps minimize oil consumption by ensuring a better seal. They are built to meet OE requirements, focusing on reducing friction and ring mass while providing a durable solution for your engine rebuild.

This set is specifically sized at 0.040 inches undersize, which is important to note for your engine build. Always ensure you are using the correct size rings for your bored cylinders to achieve proper compression and oil control.
