Product Details

The MAHLE 42087CP.020 is a premium OE-quality engine piston ring set ground to 0.020" (0.508mm) oversize specifications, designed for engines requiring cylinder bore restoration during rebuilds. As part of MAHLE Original's CP-20 series, this set delivers factory-engineered precision to restore compression, minimize blow-by, and control oil consumption.

Key Features:

  • 0.020" Oversize: Engineered for bores that have been machined 0.020" over standard size during engine reconditioning
  • CP-20 Oil Ring Assembly: Features a 20-degree ear angle for optimal side sealing against the cylinder wall, plus a chemically polished expander for enhanced oil drain-back
  • Premium Materials: Upper compression ring (UCR) in cast iron with plasma-moly facing; lower compression ring (LCR) in cast iron; oil control ring (OCR) in stainless steel with chrome facing
  • Pre-Lapped Rings: Rings are pre-lapped at the factory for immediate seating — no extended break-in period required
  • Axial Ring Heights: UCR — 1.5mm | LCR — 1.5mm | OCR — 4.0mm
  • Ring Types: UCR: RF-10PF | LCR: RBT-10 | OCR: CP-20 Shallow Groove
  • OEM-Level Quality: Manufactured to meet or exceed original equipment specifications for reliable sealing and long-term durability

MAHLE Original piston rings are produced by one of the world's foremost OE piston and ring suppliers, ensuring the same engineering standards found in factory-new engines. This set is ideal for professional engine builders performing a complete overhaul or bore-and-hone rebuild requiring 0.020" oversized components.
