Mahle Rings Dearborn Marine Ford 361/390 Engs 61-71 Ford Ind Ford Trk 360390 E Moly Ring Set

These Mahle OE piston rings are built with an E Moly coating, a tough surface treatment that helps reduce friction and wear. This is important because piston rings are constantly moving against the cylinder walls, and a good coating means they'll last longer and help your engine run more efficiently. They're designed to minimize oil consumption, which is a common concern when rebuilding or refreshing an older engine.

Mahle has a reputation for making technically advanced rings that meet original equipment requirements. This set is specifically sized at 0.040 inches undersize, meaning it's intended for cylinders that have been bored out to match this dimension during an engine rebuild. They are a solid option for a wide range of Ford and Mercury vehicles from the late 1950s through the mid-1970s, including popular models like the Ford F-100 and Mercury Colony Park, as well as many Edsel and Ford Fairlane models.
