MAHLE 3011094B Performance Piston Ring Set Bore Plasma Steel HVOF Moly - 4.320 1.0mm

The MAHLE 3011094B is a high-performance piston ring set engineered with advanced plasma steel technology and HVOF (High Velocity Oxygen Fuel) moly coating for superior durability and reduced friction. Designed for 4.320-inch bore applications, this bulk ring set features an ultra-thin 1.0mm top ring width with a 0.143-inch radial wall thickness, making it ideal for high-performance and racing applications where reduced ring mass and improved sealing are critical.

Key Features:

• SAE 9254 steel construction combined with proprietary plasma face coating extends ring life, eliminates ring breakage, reduces side wear, and minimizes groove pound-out problems
• Smaller cross-section steel ring design allows top ring groove placement closer to piston top, reducing crevice volume and unburned fuel while improving high-RPM sealing with lower ring mass
• HVOF (High Velocity Oxygen Fuel) thermal spray moly coating provides exceptional bonding strength and scuff resistance
• Developed using MAHLE's pioneering piston ring simulation and computer development tools to minimize friction and provide "free" horsepower
• 1.0mm top ring thickness for reduced weight and improved ring dynamics
• 4.320-inch bore diameter specification
• 0.143-inch radial wall thickness for optimal strength-to-weight ratio
• Bulk packaging for professional engine builders and performance shops

The lighter ring design tolerates inertial forces better and seals more effectively against the bottom of the ring groove, delivering improved performance at high engine speeds. This ring set is specifically engineered for performance and racing applications where maximum power output, durability, and precise combustion sealing are essential.
