Mahle Rings Ford 390 Eng 66-67 Merc 390/410 Engs 66-67 Moly Ring Set

This is a Mahle OE Moly Ring Set, part number 40718CP. Inside this box, you'll find the complete set of piston rings needed for a full engine rebuild on specific Ford and Mercury V8 engines from the mid-1960s. These rings are designed to work with Ford 390 engines from 1966-1967 and Mercury 390 or 410 engines from 1966-1967. They also fit a wide range of other Ford and Mercury vehicles from that era, including models like the Ford Fairlane, Mercury Monterey, and Ford Galaxie.

Mahle's approach to piston ring design focuses on reducing friction within the cylinder, which helps minimize oil consumption and can contribute to a longer service life for your engine. The moly coating on these rings helps with initial break-in and provides a durable surface that works well with the cylinder walls. This set is built to meet the demands of original equipment requirements, aiming for a balance of performance and longevity.
