MAHLE 3000181 Moly Piston Ring Set 4.325" Bore 1/16" Ductile Plasma Moly

The MAHLE 3000181 is a high-performance moly piston ring set engineered for demanding applications requiring precision bore sealing and durability. Designed for a 4.325-inch bore diameter, this ring set features advanced plasma moly coating technology for superior wear resistance and friction reduction.

Key Features:

• 4.325-inch bore diameter for precise fitment
• 1/16-inch edge width top ring configuration
• Ductile iron construction for exceptional strength and durability
• Plasma moly coating on top ring reduces friction and increases wear resistance
• Engineered to MAHLE OE specifications for reliable performance
• Enhanced seal integrity for improved compression and reduced blow-by

MAHLE's plasma moly coating process creates a porous surface that retains oil more effectively while providing a hard, wear-resistant barrier. This advanced ring set is ideal for performance rebuilds, racing applications, and demanding service conditions where standard ring sets may not provide adequate durability. The ductile iron material offers superior tensile strength compared to conventional cast iron rings, ensuring long-lasting performance under high-stress conditions.
