MAHLE 3011074 Performance Piston Ring Set Bore Plasma Steel Top Ring - 4.165 1.0mm

The MAHLE 3011074 is a high-performance piston ring set engineered for demanding racing and performance engine applications. This premium ring set features advanced materials and coatings designed to maximize power output while maintaining exceptional durability under extreme conditions.

Key Features:

• 4.165-inch bore diameter for precise fitment in performance engine builds
• 1.0mm plasma steel top compression ring for superior sealing and reduced friction
• 0.043-inch (1.0mm) top ring thickness minimizes ring mass for reduced inertia
• HVOF (High Velocity Oxygen Fuel) molybdenum coating provides exceptional wear resistance and faster break-in
• Low-tension ring design reduces friction losses and increases horsepower
• Engineered for high-RPM applications with improved ring stability
• Premium materials resist micro-welding and scuffing under high heat and cylinder pressures

MAHLE performance ring sets are manufactured to exacting tolerances and incorporate race-proven technology developed through decades of motorsports experience. The HVOF moly coating on the top ring face ensures consistent sealing performance while accelerating the critical break-in period. This ring set is ideal for naturally aspirated and forced induction performance engines requiring maximum reliability and power output.
