Product Details

The MAHLE 40141CP-030 is a precision-ground performance piston ring set engineered to exacting tolerances for reliable sealing, optimized oil control, and maximum compression retention. Manufactured by MAHLE — a globally recognized OE supplier and aftermarket performance leader — these rings are sized at +0.030" oversize, making them ideal for freshly bored or honed engine rebuilds requiring a tight, consistent fit.

MAHLE's CP-series piston rings are produced using advanced metallurgy and surface finishing processes that promote rapid ring break-in and long service life. The precision-ground profiles ensure consistent ring gap, face geometry, and radial wall thickness to meet or exceed OEM specifications.

Key Features:

  • +0.030" Oversize — designed for bored or honed engine blocks requiring oversize fitment
  • Precision-ground profiles — tight dimensional tolerances for consistent sealing across all cylinders
  • Advanced metallurgy — high-strength ductile or cast iron construction for durability and wear resistance
  • OE-quality manufacturing — produced by a Tier-1 OEM supplier trusted by major engine manufacturers worldwide
  • Optimized face geometry — promotes fast, efficient ring seating during break-in
  • Complete ring set — includes compression rings and oil control ring assembly for all cylinders

Whether you're performing a full engine rebuild or refreshing a high-mileage powerplant, the MAHLE 40141CP-030 piston ring set delivers the precision and reliability needed for a proper, long-lasting engine build.
