The King Engine Bearings CR4019XP0.25 is a high-performance connecting rod bearing set engineered specifically for Renault Flash 1.7 F2n engines with 0.25mm undersize crankshaft dimensions. This precision-machined bearing set features King's advanced XP race series construction with pMaxKote polymer coating technology for superior protection under demanding conditions.

Advanced XP Series Construction:

• Tri-metal bearing design with pMaxBlack structure for enhanced durability and load capacity
• Steel backing bonded to copper/lead babbitt layer with nickel barrier for superior stability
• 29% increase in overlay hardness compared to conventional tri-metal bearings
• 24% increase in load capacity for sustained high-stress applications
• Maintains ultra-tight wall thickness tolerance of ±0.0001 inch for consistent bearing clearances

pMaxKote Polymer Coating Benefits:

• Factory-applied nano-composite polymer coating with ceramic particles
• Provides exceptional protection during metal-to-metal contact and oil starvation conditions
• Superior resistance to wear, cavitation erosion, and seizure
• Applied with no added wall thickness, maintaining precise oil clearances
• Enhances bearing life during cold starts and low oil pressure situations

Technical Specifications:

• Application: Renault Flash 1.7 F2n engines
• Crankshaft Undersize: 0.25mm (0.010 inch)
• Construction: Tri-metal with pMaxKote coating
• Material: pMaxBlack overlay on copper alloy intermediate layer with steel backing
