MAHLE 3000384 Plasma-Moly Piston Ring Set Bore - 4.315

The MAHLE 3000384 is a high-performance moly piston ring set engineered for 4.315-inch bore applications. This precision-machined ring set features advanced plasma-moly coating on the top ring for superior wear resistance and reduced friction during engine operation.

Key Features:

• Bore size: 4.315 inches
• Top ring edge width: 0.043 inches
• Plasma-moly coating on top ring for enhanced durability
• Ductile iron construction with reduced ring width design
• Engineered for improved oil control and compression sealing
• Manufactured to OE specifications for reliable performance

MAHLE's plasma-moly coating technology provides a harder, more wear-resistant surface than traditional chrome rings while offering better scuff resistance during break-in. The reduced ring width design lowers friction and improves ring conformability to cylinder walls, making this ring set ideal for performance rebuilds and racing applications.
