MAHLE 3010993B Moly Ring Set Bore Plasma-Moly Top Ring - 4.185in 1.5mm

The MAHLE 3010993B is a high-performance piston ring set designed for precision engine builds requiring a 4.185-inch bore diameter. This premium ring set features advanced materials and coatings engineered to deliver superior sealing, reduced friction, and extended durability in demanding applications.

Key Features:

• 4.185-inch bore diameter for precise fitment
• 1.5mm plasma-moly coated steel top ring for exceptional wear resistance
• 0.151-inch radial wall (RW) thickness for optimal strength and sealing
• Plasma-moly coating reduces friction and prevents scuffing during break-in
• Performance-grade construction suitable for street and racing applications
• MAHLE OE quality engineering and materials

MAHLE piston rings are manufactured to exacting tolerances using premium materials that ensure consistent compression sealing and oil control. The plasma-moly coating on the top ring provides a hard, low-friction surface that resists wear while promoting proper cylinder wall contact during the critical break-in period. This ring set is ideal for engine builders seeking reliable performance and longevity in high-performance and racing engines.
