The MAHLE 3011070B is a high-performance piston ring set engineered for demanding racing and high-output applications. This premium ring set features advanced materials and coatings designed to maximize power, durability, and ring seal in extreme operating conditions.

Key Features:

• Plasma moly steel top ring with HVOF (High Velocity Oxygen Fuel) coating for superior wear resistance and reduced friction
• 4.145-inch bore diameter designed for popular big-bore engine builds
• Ultra-thin 1.0mm top ring for reduced friction and improved ring seal
• 0.143-inch radial wall thickness optimized for strength and flexibility
• Performance-grade materials engineered to withstand high cylinder pressures and temperatures
• HVOF molybdenum coating provides excellent scuff resistance during break-in and extended service life
• Bulk packaging for professional engine builders and race teams

MAHLE's plasma steel ring technology combines lightweight construction with race-proven durability. The HVOF moly coating creates an exceptionally hard, low-friction surface that maintains ring seal even under extreme heat and cylinder pressure. This ring set is ideal for naturally aspirated and forced-induction engines where maximum performance and reliability are critical.
