MAHLE 3011107 Performance Piston Ring Set Bore - 4.167 1/16 1/16 3/16

The MAHLE 3011107 is a high-performance piston ring set designed for precision engine builds requiring a 4.167-inch bore diameter. This premium ring set features MAHLE's advanced plasma-moly technology on the steel top compression ring, delivering superior wear resistance and reduced friction for enhanced engine performance and longevity.

Ring Set Configuration:

• Top Ring: 1/16" (0.0625") plasma-moly inlaid steel compression ring with positive twist, ductile iron construction and barrel-faced design
• Second Ring: 1/16" (0.0625") reverse twist taper-faced cast iron ring for optimal groove side sealing
• Oil Ring: 3/16" (0.190") radial wall moly three-piece oil control assembly
• Bore Size: 4.167 inches

Key Features:

• Plasma-moly coating on top ring provides excellent scuff resistance and quick break-in characteristics
• Barrel-faced top ring maintains constant cylinder wall contact throughout piston stroke
• Ultra-flat ring flanks maximize ring-to-piston sealing for reduced blowby
• Pre-lapped ring surfaces for immediate seating and minimal break-in time
• Optimized ring tension reduces friction while maintaining proper cylinder seal
• CNC-controlled gap chamfer optimizes compression and minimizes blowby

MAHLE ring sets are engineered using advanced piston ring simulation and computer development tools, resulting in rings that deliver measurable power gains through friction reduction. The 0.190-inch radial wall oil ring provides excellent oil control while the reverse-twist second ring enhances sealing and reduces oil consumption. This ring set is ideal for performance and racing applications where durability, sealing efficiency, and power output are critical.
