When you're rebuilding the top end of your engine, a good set of piston rings is crucial for proper sealing and performance. This Mahle OE Moly Ring Set, part number 40139.030, is designed for Ford and GM 5.4L and 5.8L engines, fitting a wide range of vehicles from the late 1950s through the late 1960s, including models like the Ford Fairlane and Mercury Monterey.
