Product Details

The MAHLE 40203CP-030 is a precision-ground performance piston ring set engineered for high-performance and racing applications. MAHLE's advanced manufacturing process ensures exceptional ring-to-bore conformability and consistent sealing characteristics throughout the engine's operating range.

Key Features:

  • Precision-ground surface finish for optimal oil control and reduced friction
  • Low-tension design reduces parasitic drag and increases horsepower
  • Premium alloy steel construction with advanced coating technology
  • Enhanced heat dissipation for improved durability under high-load conditions
  • Pre-gapped for ease of installation and proper end-gap tolerance
  • Designed for performance rebuilds and racing applications

MAHLE piston rings are manufactured to strict OE specifications and incorporate decades of motorsports engineering experience. The CP-030 oversize provides proper cylinder wall clearance for bored blocks, ensuring reliable compression sealing and long-term performance. Each ring set includes top compression rings, second compression rings, and oil control ring assemblies.
