MAHLE 3011125B Piston Ring Set Bore Plasma Moly Top Ring - 4.605

The MAHLE 3011125B piston ring set is engineered for high-performance engine builds requiring a 4.605-inch bore diameter. This premium ring set features advanced materials and coatings designed to deliver exceptional sealing, durability, and reduced friction in demanding applications.

Key Features:

• Plasma moly steel top compression ring for superior wear resistance and heat dissipation
• 4.605-inch bore diameter with 0.0625-inch (1/16-inch) ring width
• 0.190-inch radial wall thickness for optimal tension and conformability
• Bulk moly coating reduces friction and accelerates break-in period
• Precision-manufactured to OE specifications for reliable compression sealing
• Suitable for performance rebuilds and racing applications

MAHLE's plasma moly technology bonds molybdenum to the ring face at the molecular level, creating a durable surface that withstands extreme cylinder pressures and temperatures. The bulk moly treatment on additional rings provides consistent lubrication properties throughout the ring pack, ensuring balanced performance across all compression and oil control functions.
