MAHLE 3011028B Performance Plasma Moly Piston Ring Set Bore - 4.630 1.0mm

The MAHLE 3011028B is a high-performance piston ring set designed for precision engine builds requiring a 4.630-inch bore diameter. This premium ring set features advanced Plasma Moly steel construction on the top compression ring, delivering superior wear resistance and improved sealing under demanding conditions.

Key Features:

• Plasma Moly steel top compression ring for enhanced durability and heat resistance
• 1.0mm ring thickness with .143 radial wall (RW) for optimal tension and sealing
• 4.630-inch bore diameter for performance engine applications
• Engineered for reduced friction and improved ring seal
• Moly-faced design reduces break-in time and cylinder wear
• Manufactured to MAHLE's OE and racing quality standards

MAHLE's Plasma Moly technology bonds a molybdenum coating to the ring face at the molecular level, providing exceptional scuff resistance during critical break-in periods and long-term durability. This ring set is ideal for high-performance street engines, racing applications, and precision rebuilds where maximum power and reliability are essential.
