King Engine Bearings MB582XP XP Series Tri-Metal Main Bearing Set Ford 2.0/2.3L 8V

The King Engine Bearings MB582XP is an XP Series tri-metal performance main bearing set engineered for Ford 2.0L and 2.3L 8-valve engines. Built for high-load, long-duration racing applications, the XP Series features King's proprietary pMax Black tri-metal copper-lead construction with nickel barrier and SecureBond adhesion — delivering up to 15%–30% greater load capacity than traditional bearings.

The pMax Black overlay undergoes a metallurgical hardening process that makes it 24% harder than conventional tri-metal race bearings, providing superior resistance to surface fatigue under sustained extreme loads. These bearings are specifically designed for performance applications using forged steel aftermarket crankshafts that generate high loads for extended periods.

XP Series Construction:

• Enhanced tri-metal copper-lead construction with nickel barrier
• SecureBond adhesion process for superior stability between top and intermediate layers
• 0.0005" metallurgically hardened performance overlay for improved fatigue resistance
• Mains are half-grooved for uncompromised lower shell load capacity

King Performance Bearing Features:

• Bull's Eye Tolerance — Wall thickness matched to ±0.0001", the closest tolerances in the industry
• Increased Height — Greater bearing height improves bore contact, heat transfer, and reduces spin potential at high RPM
• Improved Oiling — Mains feature enlarged, chamfered oil holes for better lubrication flow
• Medium Eccentricity — Optimizes load distribution and oiling characteristics
• Narrowed Design — Mains and rods narrowed to accommodate large-radius crankshafts
• Dowel Holes — Available with or without dowel holes depending on application

Ideal Applications:

• Circle track racing
• Off-road racing
• Offshore powerboat racing
• Any high-load, long-duration racing requiring forged steel crankshafts

King Engine Bearings offers the industry's widest selection of sizes and special clearance options, ensuring the right fit for even the most demanding performance builds.
