Mahle Rings GM 6.2L LS3 2007-2010 LS3 L92 L84 L9H L99 Moly Ring Set

Mahle Original piston ring sets are designed for easy installation and immediate seating, virtually eliminating break-in time. They feature optimized ring materials, coatings, and tension for reduced friction and extended life. Compression rings have a barrel-faced contact area for efficient compression and CNC-controlled gap chamfer to reduce 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 have a 20-degree ear angle for optimal side seal against the cylinder wall and a special chemical polish on the oil ring expander for enhanced oil drainback. These features provide unmatched quality and ease of installation, making them a preferred choice for engine builders.
