Product Details

The MAHLE 40565CP.030 is a premium plasma-moly piston ring set designed for engines with a 4.030" bore (+.030" oversize). Built to OE-level standards, this CP-series ring set delivers optimized sealing, reduced friction, and extended service life for engine rebuilds and overhauls.

Key Features:

  • Plasma-moly top compression ring (UCR): Cast iron construction with a plasma-moly facing for superior wear resistance and quick seating
  • Upper compression ring type RF-13PF: Barrel-faced contact area for more efficient compression sealing and a CNC-controlled gap chamfer to minimize blow-by
  • Lower compression ring (LCR): Cast iron with taper-face reverse twist (RBT-10 type) design for improved groove-side sealing and enhanced cylinder wall contact
  • CP-20 oil control ring assembly (OCR): Stainless steel construction with chrome-faced rails and a 20-degree ear angle for optimal side sealing against the cylinder wall
  • Chemical-polished oil ring expander: Promotes enhanced oil drain-back and reduced oil consumption
  • Pre-lapped rings: Seat immediately upon installation, virtually eliminating traditional break-in time
  • Ring dimensions: Upper compression ring 5/64", lower compression ring 5/64", oil control ring 3/16" axial height

MAHLE Original piston ring sets are engineered to meet stringent OE requirements, reducing ring mass and friction while minimizing engine oil consumption for longer service life. The installer-friendly design ensures rings cannot be incorrectly installed, saving time during engine assembly. Ideal for engine rebuilders and professional shops performing re-ring jobs or complete engine overhauls.

Hello, Great site, but the colors of the highlighted items are hard to see. You might try having better contrast on the selected item versus the non selected item. IE: The date, state, etc

Autoplicity had fast shipping at a low price compared to other competitors. The price for the item itself was the lowest around so I think I got a good deal or my car. Would buy from again!

Good price, not an accurate picture of item
