King Engine Bearings MB7084XPC0.25 Performance Main Bearing Set with pMaxKote Coating

The King Engine Bearings MB7084XPC0.25 is a high-performance main bearing set designed for Toyota 3.0L engines. This precision-engineered bearing set features King's advanced XPC series construction with factory-applied pMaxKote polymer coating for superior wear resistance and durability in demanding applications.

Advanced XPC Series Construction:

• Tri-metal design with copper lead construction, nickel plate barrier, and lead/tin/copper Babbitt overlay on steel backing
• pMaxKote nano-composite polymer coating applied over pMaxBlack overlay for enhanced seizure and wear resistance
• Polymer coating adds no additional thickness, maintaining original precision wall thickness dimensions
• Superior load capacity of 10,200 PSI in the overlay layer
• Industry-leading wall thickness tolerance of ±0.0001 inch for consistent performance

Key Features:

• 0.25mm oversize bearing dimensions for reground crankshafts
• Narrowed design for large radii crankshafts
• Enlarged, chamfered oil holes for improved lubrication flow
• U-Groove oil delivery system maintains oil flow integrity while increasing bearing load capacity
• RadiaLock crush height optimization for superior bearing stability
• Elliptix eccentricity design from elasto-hydrodynamic analysis

Application:

• Ideal for circle track, drag racing, and other high-performance applications with steel crankshafts
• Designed for engines requiring 0.25mm oversize main bearings
