MAHLE 51245 Original Standard Engine Piston Ring Set – Cast Iron, 3.736 in. Bore, V6

The MAHLE Original 51245 is a precision-engineered engine piston ring set designed to meet or exceed OEM specifications. MAHLE is a globally recognized supplier of engine components to major OEMs, and their Original line brings that same manufacturing quality to the aftermarket replacement market.

Piston rings are critical sealing components that control oil consumption, maintain compression, and transfer heat from the piston to the cylinder wall. Replacing worn or damaged piston rings restores engine compression and reduces oil burning, helping bring aging or rebuilt engines back to factory performance standards.

Key Features:

• OEM-quality construction engineered to meet original equipment specifications
• Precision-ground ring surfaces for proper cylinder wall sealing and controlled break-in
• Manufactured from high-grade cast iron or steel alloy depending on ring type
• Designed to minimize blow-by and restore proper compression
• Helps control oil consumption and reduce exhaust emissions
• Complete set includes compression rings and oil control ring assembly
• Consistent dimensions and tolerances for reliable fit and long service life

MAHLE Original piston ring sets are a trusted choice for professional engine builders and technicians performing engine overhauls, rebuilds, or repairs. Each set is manufactured under strict quality control standards backed by MAHLE's decades of OEM engine component expertise.
