MAHLE 40452CP.060 Plasma-Moly Engine Piston Ring Set Oversize - 0.060

The MAHLE 40452CP.060 is a premium plasma-moly engine piston ring set ground to a +0.060" oversize specification for use in engines with bored or worn cylinders brought to that oversize dimension. Engineered to OE standards, this set delivers reduced friction, minimized oil consumption, and extended service life.

Key Features:

• Plasma-moly top ring coating for superior wear resistance, scuff resistance, and fast break-in
• Barrel-faced upper compression ring with CNC-controlled gap chamfer to optimize compression sealing and reduce blow-by
• Reverse-twist second (intermediate) ring with taper-race machining for enhanced groove side sealing and oil control
• CP-20 three-piece oil control ring assembly featuring a 20-degree ear angle for best-in-class cylinder wall sealing and a chemically polished expander for improved oil drain-back
• Ring materials and tension optimized per application to minimize friction while maximizing ring life
• Pre-lapped for immediate seating, virtually eliminating traditional break-in time
• +0.060" oversize — designed for cylinders bored or honed to the 0.060" over specification
• Manufactured by MAHLE, the world's largest producer of piston rings and manufacturer of the legendary Perfect Circle ring line

This piston ring set is a direct-fit, drop-in replacement suitable for rebuilding or freshening engines where cylinders have been bored to the +0.060" oversize. All components are new — no remanufactured parts included.
