Product Details

The MAHLE 40720-030 is a precision-ground piston ring set engineered to OEM and performance standards. MAHLE is a globally recognized manufacturer of engine components, supplying original equipment to major automotive manufacturers and delivering the same quality to the aftermarket. These piston rings are manufactured to exacting tolerances to ensure proper cylinder seal, optimized oil control, and consistent compression across all cylinders.

Key Features:

  • Precision-ground construction for tight tolerances and reliable ring seal
  • OEM-grade materials — engineered for durability and long service life
  • 030 oversize bore (.030" / 0.76mm over standard) for use in freshly bored or honed cylinders
  • Designed to restore proper compression and reduce blow-by in worn engines
  • Effective oil control to minimize oil consumption and maintain engine cleanliness
  • Manufactured to MAHLE's strict quality and dimensional standards

The -030 suffix indicates these rings are sized for a 0.030-inch overbore, making them the correct choice for engine rebuilds where cylinders have been bored 0.030" over the standard factory diameter. Each set includes the top compression ring, second compression ring, and oil control ring assembly for a complete cylinder rebuild solution.

MAHLE piston rings are a trusted choice for professional engine builders and OEM suppliers worldwide, delivering consistent performance in passenger car, light truck, and performance engine applications.
