Product Details

The MAHLE 3021264 is a high-performance piston ring set designed for precision engine builds requiring a 4.045-inch bore diameter. This Napier-style ring set features MAHLE's THM-13 performance coating technology, engineered to deliver improved sealing, reduced friction, and enhanced durability under demanding operating conditions.

Key Features:

  • 4.045-inch bore diameter for precise fitment
  • 1.5mm top ring thickness for optimal sealing performance
  • Napier-style second ring design for superior oil control
  • THM-13 performance coating reduces friction and wear
  • Plain ring configuration without special groove requirements
  • Manufactured to MAHLE's OE quality standards

MAHLE piston rings are precision-engineered using advanced materials and coatings developed through decades of motorsport and OEM experience.
