MAHLE 3011072 Performance Piston Ring Set Bore Plasma Steel Top Ring - 4.155 1.0mm

The MAHLE 3011072 Performance Piston Ring Set is engineered for high-performance engine builds requiring precision fit and maximum durability. This ring set features a 4.155-inch bore diameter and is designed for demanding applications where superior ring seal and longevity are critical.

Key Features:

• Plasma Steel top ring with 1.0mm thickness for exceptional strength and heat resistance
• HVOF (High Velocity Oxygen Fuel) molybdenum coating provides superior wear resistance and scuff protection
• 0.143-inch radial wall (RW) thickness ensures structural integrity under high cylinder pressures
• 4.155-inch bore diameter for precise fitment in performance engine applications
• Engineered for reduced friction and improved ring seal compared to standard cast rings
• Premium MAHLE quality with tight tolerances for consistent performance

This performance ring set is ideal for street/strip builds, forced induction applications, and high-RPM naturally aspirated engines where stock ring packages cannot withstand the increased thermal and mechanical loads. The advanced coating technology and precision manufacturing deliver reliable cylinder sealing and extended service life in demanding conditions.
