MAHLE 3011087 Performance Piston Ring Set Bore Plasma Steel HVOF Moly - 4.270

The MAHLE 3011087 performance piston ring set is engineered for high-performance and racing applications requiring maximum durability and reduced friction. This advanced ring set features a 4.270-inch bore diameter with a precision 1.0mm thickness profile and 0.143-inch radial wall dimension.

Advanced Coating Technology:

The top compression ring utilizes plasma steel construction with HVOF (High Velocity Oxygen Fuel) molybdenum coating, providing superior wear resistance and scuff protection under extreme cylinder pressures and temperatures. This proprietary thermal-spray coating process ensures exceptional bonding strength and extended service life compared to conventional ring materials.

Key Features:

• 4.270-inch bore diameter for large displacement performance engines
• 1.0mm top ring thickness for reduced friction and improved sealing
• Plasma steel top ring with HVOF molybdenum face coating
• 0.143-inch radial wall dimension optimized for strength and flexibility
• Designed to minimize ring flutter at high RPM
• Pre-lapped for quick seating and reduced break-in time
• Barrel-faced contact area for efficient compression sealing

MAHLE performance ring sets are developed using advanced piston ring simulation and computer modeling to deliver measurable horsepower gains by reducing parasitic friction losses. Each ring set is precision-manufactured to exacting tolerances, making them the choice of professional engine builders and racers worldwide.
