The King Engine Bearings MB1332XP0.25-2 is a precision-engineered main bearing from King's XP (Extra Performance) Series, designed for engines where the crankshaft main journals have been ground to a +0.25mm undersize. King Engine Bearings is a globally recognized manufacturer of high-performance and OE-replacement engine bearings trusted by professional engine builders and motorsport teams worldwide.

XP Series Technology:

• Tri-metal construction — steel backing with copper-lead or aluminum intermediate layer and a precision overlay for superior load capacity
• XP polymer coating — King's proprietary surface treatment that reduces friction, improves conformability, and enhances resistance to dry-start wear
• +0.25mm oversize — engineered for crankshafts that have been machined 0.25mm under standard journal diameter during engine reconditioning
• Tight tolerances — manufactured to exacting clearance specifications for consistent oil film and optimal hydrodynamic lubrication
• High fatigue strength — capable of withstanding the elevated loads found in performance, towing, and high-mileage rebuilt engines
• Chamfered edges for compatibility with radius-ground crankshaft journals
• Precision-formed tang and locating features for positive bearing positioning

The XP Series is an ideal choice for engine rebuilds requiring oversize bearings, offering a significant upgrade over standard OEM replacement bearings. Whether used in a street rebuild or a performance application, the MB1332XP0.25-2 delivers the durability and precision that King Engine Bearings is known for.
