Mahle Rings GM 5.3L V8 GenV L83/L8B/L8X 2014-Up Direct Injection Engine M9033 OES Moly Ring Set

The Mahle 42216CP is a premium piston ring set designed for Gen V 5.3L LT engines with a 3.780" bore, compatible with 2014 and newer models.

These Mahle Original piston ring sets are pre-lapped for immediate seating, minimizing break-in time. They feature optimized ring materials, coatings, and tension for reduced friction and extended life. The compression rings have a barrel-faced contact area and CNC-controlled gap chamfers for efficient compression and reduced blowby. Intermediate rings use a reverse twist design for better groove sealing, and the CP-20 oil ring assemblies include a 20-degree ear angle for a superior side seal and a chemical polish on the expander for enhanced oil drainback.
