Product Details

King Engine Bearings MB5263XPC Performance Main Bearings deliver race-proven durability and precision for high-performance engine builds. These main bearings feature King's proprietary pMax Black tri-metal construction with an advanced polymer coating for enhanced protection during critical start-up and high-load conditions.

Key Features:

  • XPC (Extra Performance Coating) provides superior protection against wear and scuffing
  • Tri-metal construction with steel backing, aluminum-tin alloy, and polymer overlay
  • Precision manufactured to strict tolerances for optimal oil clearances
  • Increased fatigue strength for high-performance and racing applications
  • Enhanced embedability to trap contaminants and protect the crankshaft
  • Suitable for forced induction, nitrous, and naturally aspirated builds

King Performance bearings are engineered for enthusiasts and professionals who demand maximum reliability under extreme conditions. The XPC coating significantly reduces friction during dry starts and provides an extra layer of protection when oil flow is interrupted, making these bearings ideal for competition engines and high-output street builds.

The only problem was confusion with process and delivery information. And the picture of the generator wasn't what my pump was for. Despite that, it was right product delivered as fast as Amazon which brought me comfort to the confusion. Thanks for your service.

So far so good ! Transaction was smooth and perfect.
