The MAHLE 41897CP is a premium OE replacement piston ring set designed with original equipment form, fit, and function. This standard bore set features a 3.386-inch bore diameter with plasma-moly face coating for superior wear resistance.

Technical Specifications:

• Bore Diameter: 3.386 inches (86.0mm)
• Top Ring: 1.20mm thickness, carbon steel construction
• Second Ring: 1.50mm thickness, cast iron material
• Oil Ring Assembly: 2.50mm thickness, stainless steel
• Face Coating: Plasma-Moly for enhanced durability
• Oversize: Standard (not oversized)

Advanced Engineering Features:

• SAE 9254 high alloy steel base material provides higher tensile and yield strength, extended fatigue resistance, and increased material hardness
• Compression rings feature barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by
• Intermediate rings use reverse twist design for better groove side sealing and taper race machining to enhance contact
• Exclusive CP-20 oil ring assemblies with 20-degree ear angle provide the best possible side seal against the cylinder wall
• Ring materials, coatings, and ring tension optimized for reduced friction and extended life

MAHLE second rings deliver superior oil control, improved combustion gas management, top ring stability, and sealing for optimal performance with minimal power loss. As one of the largest OE piston ring manufacturers in the world, MAHLE leads the industry for the latest piston ring technology.
