Product Details

The MAHLE 51807 is a precision-ground piston ring set engineered to OEM and performance standards by one of the world's leading engine component manufacturers. MAHLE's piston rings are produced to exacting tolerances, ensuring proper cylinder sealing, optimal oil control, and reliable compression retention across a wide range of operating conditions.

Key Features:

  • Precision-Ground Finish: Each ring is ground to tight dimensional tolerances for consistent gap clearance and superior sealing against the cylinder wall
  • OEM-Grade Materials: Manufactured from high-strength cast iron or ductile iron alloys, consistent with MAHLE's original equipment supply standards
  • Advanced Ring Face Coating: Features a wear-resistant coating (such as chrome or nitride treatment) to extend service life and reduce friction
  • Three-Piece Ring Set Design: Typically includes top compression ring, second compression ring, and a three-piece oil control ring assembly
  • Proper Tension and Radial Depth: Engineered ring tension ensures efficient oil scraping and consistent compression sealing without excessive drag
  • Direct-Fit Replacement: Designed as a direct OEM-spec replacement for straightforward installation without modification

MAHLE is a globally recognized Tier 1 OEM supplier trusted by major automotive manufacturers. The MAHLE 51807 piston ring set delivers the same quality found in factory-built engines, making it an ideal choice for engine rebuilds, overhauls, or performance upgrades requiring reliable, long-lasting compression and oil control.
