Product Details

The MAHLE 4065MS piston ring set is designed for engines with a 4.060" bore diameter with an additional 0.005" oversize. This file-fit ring set features standard tension construction and a 1/16", 1/16", 3/16" configuration for top, second, and oil ring widths.

Ring Specifications:

  • Top ring: Ductile iron with plasma moly coating and barrel face profile for superior sealing
  • Second ring: Cast iron with reverse twist design for improved oil control
  • Oil ring: 3-piece standard tension design for optimal lubrication management
  • File-fit style allows precise end gap customization during installation

MAHLE utilizes advanced piston ring simulation and computer development to engineer rings that minimize friction and unlock free horsepower. The ultra-flat ring flanks maximize ring-to-piston groove sealing, reducing blow-by and improving combustion efficiency. This results in measurable power gains on the dyno and improved performance on the track.

Applications: Suitable for high-performance engine builds requiring precise bore specifications and standard tension ring packages.
