Product Details

The MAHLE 42240CP Engine Piston Ring Set is a premium OE-quality replacement ring set engineered to meet or exceed original equipment specifications. MAHLE is one of the world's largest OE piston ring manufacturers, bringing direct factory engineering expertise to every replacement set they produce.

This CP-series ring set features a three-piece configuration — upper compression ring (UCR), lower compression ring (LCR), and oil control ring (OCR) — each manufactured from carefully selected materials and finished with advanced surface treatments designed to reduce friction, control oil consumption, and extend engine service life.

Ring Material & Construction:

  • Upper Compression Ring (UCR): Stainless steel base material with Gas Nitride / PVD facing — Ring Type RF-12NGDV
  • Lower Compression Ring (LCR): Carbon steel base material with chrome facing — Ring Type TCG-13UF (Napier-style for superior oil scraping)
  • Oil Control Ring (OCR): Stainless steel base material with chrome facing — Ring Type CP-20 with exclusive 20-degree ear angle

Key Specifications:

  • UCR Axial Height: 1.2mm
  • LCR Axial Height: 1.2mm
  • OCR Axial Height: 2.0mm
  • Shallow groove design for precise fitment
  • Material Grade: Standard

Key Features & Benefits:

  • Designed with OE form, fit, and function for a direct replacement
  • SAE 9254 high-alloy steel base material delivers higher tensile and yield strength, extended fatigue resistance, and increased material hardness
  • CP-20 oil control ring utilizes a 20-degree ear angle for optimal side sealing in the piston oil ring groove and simplified installation
  • Napier-style second ring provides superior combustion gas management, top ring stability, and reduced power loss
  • Advanced surface coatings minimize friction and wear for longer service intervals
  • Engineered to reduce engine oil consumption and support lower emissions

MAHLE replacement piston rings are the trusted choice for professional engine builders and rebuild shops seeking OE-level reliability without compromise.
