Product Details

This is a Mahle OE Moly Ring Set, part number 40720.030, designed for Ford 428 cubic inch engines from 1966 through 1970. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. If you're rebuilding the top end of your classic Ford, Mercury, or AC vehicle, a fresh set of piston rings is a fundamental part of restoring performance and reliability.

Mahle engineers these rings with a focus on reducing friction, which can lead to improved engine efficiency and a longer service life. The moly coating on the top ring helps with initial seating and wear resistance, ensuring a good seal right away and maintaining it over time. This attention to detail means less oil burning and a more consistent performance from your engine.

This set fits a wide range of vehicles, including popular models like the Ford Mustang, Ford Torino, and Mercury Cougar from the specified years. Ensure you check the full fitment list to confirm compatibility with your specific application. When installing, always refer to the manufacturer's service manual for proper ring gap and installation procedures.
