What does the 0.030 in the part number mean?

The '40722.030' indicates that this ring set is 0.030 inches undersize. This is a common sizing for engine rebuilding when cylinder walls have been honed or bored out to a larger diameter.

Are these rings compatible with all 440 engines?

This set is specifically designed for Chrysler 440 engines manufactured between 1966 and 1978. It's important to verify your engine's displacement and year range before purchasing.

What is the benefit of chrome plating on piston rings?

Chrome plating provides a hard, durable surface for the piston ring. This helps improve wear resistance against the cylinder wall, leading to a longer service life and maintaining a good seal for efficient combustion.

Product Details

If you're rebuilding the engine in your classic Mopar, Mahle OE piston rings are a solid choice. These rings are designed for Chrysler 440 cubic inch engines from 1966 through 1978, covering a wide range of popular vehicles like the Dodge Charger, Plymouth Barracuda, and Chrysler New Yorker. They play a crucial role in sealing the combustion chamber, controlling oil consumption, and reducing friction for better engine performance and longevity.
