The MAHLE 3011014B is a high-performance piston ring set engineered for demanding engine applications. This precision-manufactured ring set features a 4.020-inch bore diameter and incorporates advanced materials and coatings for superior performance and durability.

Key Features:

• Plasma Moly steel top compression ring for exceptional wear resistance and heat dissipation
• 4.020-inch bore diameter with 0.0625-inch ring thickness
• 0.190-inch radial wall (RW) design for optimal sealing and strength
• Molybdenum-coated compression ring surface reduces friction and extends ring life
• Precision-engineered to MAHLE's OE and performance specifications
• Complete ring set includes all necessary rings for one piston

MAHLE's plasma moly coating provides a micro-porous surface that retains oil for improved lubrication during break-in and operation, while the steel construction ensures dimensional stability under high temperatures and pressures. Ideal for performance rebuilds, racing applications, and high-output street engines requiring reliable cylinder sealing.
