MAHLE 3010986 Moly Ring Set Bore Plasma-Moly Top Ring - 4.150 1.5mm

The MAHLE 3010986 is a high-performance piston ring set engineered for precision-built engines with a 4.150-inch bore diameter. This premium ring set features advanced materials and coatings designed to deliver superior sealing, reduced friction, and enhanced durability in demanding applications.

Key Features:

• 4.150-inch bore diameter for precise fitment in performance engine builds
• 1.5mm top ring thickness provides excellent sealing and ring stability
• Plasma-moly steel top ring coating reduces friction and improves wear resistance
• 0.151-inch radial wall (RW) thickness ensures structural integrity under high cylinder pressures
• Premium MAHLE engineering for reliable performance in street and racing applications
• Designed to maximize compression sealing while minimizing oil consumption

MAHLE piston rings are manufactured to exacting tolerances and feature advanced surface treatments that promote rapid break-in and long service life. The plasma-moly coating on the top ring face provides a hard, low-friction surface that resists scuffing during initial engine start-up and maintains consistent sealing throughout the ring's service life. This ring set is ideal for performance engine builders seeking OEM-quality components with racing-proven technology.
