MAHLE 3011075 Performance Plasma Steel Piston Ring Set 4.170in Bore 1.0mm Top Ring HVOF Moly

The MAHLE 3011075 is a high-performance piston ring set engineered for demanding engine builds requiring superior sealing, heat resistance, and long-term durability. This set features a Plasma Steel top ring with a 1.0mm face width and a 4.170-inch bore diameter, making it ideal for performance and racing applications where standard cast iron rings fall short.

The top ring utilizes a HVOF (High Velocity Oxygen Fuel) Molybdenum coating on the running face. HVOF Moly is a thermally sprayed coating process that produces an exceptionally dense, hard, and wear-resistant surface. This results in improved ring seal, reduced blow-by, and extended service life even under extreme combustion temperatures and pressures.

Key Features:

• Bore Size: 4.170 inches
• Top Ring Face Width: 1.0mm
• Ring Wall (RW): .143 inches
• Top Ring Material: Plasma Steel — offers higher tensile strength and better thermal stability than conventional ductile iron rings
• Top Ring Coating: HVOF Moly — provides superior wear resistance and excellent break-in characteristics
• Performance-oriented design suited for high-horsepower, high-RPM, or forced-induction engine applications
• Manufactured by MAHLE Motorsports, a globally recognized OEM and performance engine component supplier

MAHLE is an industry leader in piston and ring technology, supplying both OEM production engines and professional motorsports programs worldwide. The 3011075 ring set reflects MAHLE's commitment to precision manufacturing and advanced surface engineering, delivering race-proven performance in a streetable package.
