The King Engine Bearings MB7776GPC is a premium racing main bearing set engineered for BMW N55 B30A, N53 B30A, and N52 B30A engines. This high-performance bearing set features King's advanced GPC (polymer-coated) tri-metal construction designed specifically for extreme load race applications, diesel performance builds, and sprint cars.

GPC Tri-Metal Technology:

• Silver-based tri-metal material capable of withstanding up to 17,000 PSI—significantly exceeding conventional race materials that peak at 11,000 PSI
• Intermediate lead-bronze layer over steel backing, topped with a silver overlay containing solid lubricant additives distributed throughout the matrix
• Factory-applied nano-composite polymer coating provides critical protection during oil starvation and metal-to-metal contact scenarios
• Polymer coating adds no additional thickness, maintaining original precision wall thickness dimensions
• Lead-free construction prioritizes environmental sustainability without compromising performance

Performance Engineering Features:

• Optimized crush height obtained through precision engineering processes specific to each performance bearing application
• Optimized eccentricity values achieved through elasto-hydrodynamic analysis and dynamic calculations
• Superior wall thickness tolerance ensuring minimal variation shell-to-shell for consistent performance
• 7-pair complete main bearing set for full crankshaft coverage
