Product Details

The MAHLE 4165MS piston ring set is designed for 4.165" bore engines and features a drop-in standard tension configuration with 1/16", 1/16", 3/16" ring widths. This three-ring set delivers proven performance for street and performance applications.

Ring Configuration:

  • Top ring: Ductile iron with plasma moly coating and barrel face profile for superior wear resistance and oil control
  • Second ring: Cast iron reverse twist design for improved compression sealing
  • Oil ring: 3-piece standard tension design for optimal oil control

Advanced Engineering:

  • Ultra-flat ring flanks maximize ring-to-piston groove sealing
  • Computer-optimized design minimizes friction for increased horsepower
  • Plasma moly coating provides exceptional durability and scuff resistance
  • Drop-in fitment for simplified installation

MAHLE pioneered the use of piston ring simulation and advanced development tools to create rings that reduce friction and unlock free horsepower. The precision engineering is measurable on the dyno and proven on the track, making these rings an excellent choice for engine builders seeking reliable performance.
