Product Details

The MAHLE 4155MS piston ring set is engineered for 4.155" bore applications and features a drop-in design with standard tension configuration. This three-ring set includes 1/16" top ring, 1/16" second ring, and 3/16" oil ring, delivering proven performance for engine rebuilds and high-performance applications.

Key Features:

  • 4.155" bore diameter for precise fitment
  • Top ring: Ductile iron with plasma moly coating and barrel face configuration for superior wear resistance
  • Second ring: Cast iron reverse twist design for optimal oil control
  • Oil ring: 3-piece standard tension construction
  • Ultra-flat ring flanks maximize ring-to-piston sealing and reduce blow-by
  • Advanced design minimizes friction for free horsepower gains

MAHLE pioneered piston ring simulation and computer development tools to engineer rings that reduce friction while maintaining excellent sealing. The plasma moly coating on the top ring provides exceptional durability and scuff resistance, while the reverse twist second ring ensures proper oil control. This ring set is ideal for performance enthusiasts and professional engine builders seeking reliable, dyno-proven components.
