Mahle Rings Cadillac 4.6L 8 Cyl Northstar System 1996-2002 Moly Ring Set

MAHLE® piston rings are technically advanced, driven by OE requirements, reducing friction and ring mass while minimizing engine oil consumption and providing longer service life. Mahle Original piston ring sets are installer-friendly and pre-lapped to seat immediately. Ring materials, coatings, and tension are optimized for reduced friction and extended life. Compression rings feature a barrel-faced contact area and CNC-controlled gap chamfer for efficient compression and reduced blow-by. Intermediate rings have a reverse twist design for better groove side sealing and taper race machining to enhance contact. The CP-20 oil ring assemblies feature a 20-degree ear angle for the best possible side seal against the cylinder wall, and a special chemical polish on the oil ring expander offers enhanced oil drain back.
