Product Description

The King MB5280HP main bearing set is precision-engineered for Ford's SOHC 4.6L and 5.4L V8 engines spanning 1993-2010. Featuring the Alecular™ bi-metal design and HP-series hardened overlay, these bearings resist high-load wear and extrusion - ideal for drag, circle track, and street/strip performance builds. Bull's Eye Wall Tolerance™ ensures craftsman-level oil clearance precision, while grooved shells and included thrust washers simplify high-performance engine assembly.

Constructed for durability, these bearings handle the rigors of nodular cast-iron cranks and occasional metal-to-metal contact. Offering strengths comparable to race-grade Canada bearings (~8,000 psi load capacity, 24% harder overlay), the MB5280HP set upgrades stock builds with race-level toughness without altering OE dimensions. Perfect for engine rebuilds requiring reliability, precision, and resilience under extreme conditions.
