MAHLE 42033CP Premium Plasma-Moly Piston Ring Set

The MAHLE 42033CP is a premium engine piston ring set engineered to OEM and beyond specifications. As a global leader in piston and ring manufacturing, MAHLE designs these rings using advanced computer simulation tools to minimize friction and maximize sealing performance, delivering reliable power and longevity in every application.

Key Features:

• Pre-lapped for fast seating — rings seat immediately upon installation, virtually eliminating traditional break-in time
• Barrel-faced top compression rings — promotes efficient compression and reduces blow-by
• CNC-controlled gap chamfer — optimizes ring gap for superior compression retention
• Reverse-twist intermediate rings — improve groove-side sealing with taper race machining for enhanced cylinder wall contact
• CP-20 Oil Ring Assembly — features a 20-degree ear angle for best-in-class side sealing against the cylinder wall
• Chemically polished oil ring expander — promotes enhanced oil drainback for improved oil control
• Optimized ring tension and coatings — materials engineered per application for reduced friction and extended service life
• Plasma-moly face coating — provides excellent scuff resistance and durability under high heat and pressure

MAHLE piston ring sets are the preferred choice of professional engine builders for engine rebuilds and performance upgrades. The 42033CP is built to restore proper compression, reduce oil consumption, and return engines to like-new performance standards.
