Product Details

The MAHLE 4030MS piston ring set is engineered for 4.030" bore applications with a drop-in design and standard tension configuration. This three-ring set features 1/16" top ring, 1/16" second ring, and 3/16" oil ring widths, providing optimal sealing and performance for high-performance engine builds.

Key Features:

  • 4.030" bore diameter for precise fitment
  • Drop-in installation for easy assembly
  • Standard tension design balances sealing and friction
  • Ductile iron top ring with plasma moly barrel face coating for superior wear resistance
  • Cast iron second ring with reverse twist design for improved oil control
  • 3-piece oil ring assembly for exceptional oil management
  • Ultra-flat ring flanks maximize ring-to-piston sealing contact

MAHLE pioneered computer simulation and advanced development tools to engineer piston rings that minimize friction and unlock free horsepower. The plasma moly coating on the top ring provides exceptional durability and scuff resistance, while the reverse twist second ring enhances cylinder wall sealing. Designed and tested for performance applications where reliability and power gains matter.
