Main Bearing Set - Ford 4.6L SOHC 16V

The Main Bearing Set - Ford 4.6L SOHC 16V by King Bearings is engineered for professionals and enthusiasts rebuilding or upgrading Ford modular engines. As the foundation of any crankshaft assembly, main bearings distribute rotational loads across the engine block while maintaining precise clearances under extreme combustion pressures. Whether you're restoring a stock 4.6L or preparing a performance build, this bearing kit ensures the structural integrity and longevity your engine demands.

King Bearings' XP series main bearing set delivers enhanced load capacity and thermal stability through proprietary copper-lead composition and precision manufacturing. The 0.25 mm undersize specification accommodates crankshaft regrinding—a critical consideration when salvaging a worn or damaged crank. Proper bearing clearance (typically 0.0015–0.0025 inches) is essential for adequate oil film formation; undersized bearings allow machinists to restore correct journal dimensions without sacrificing bearing wall thickness. The complete kit eliminates guesswork during assembly, ensuring all five main saddle positions receive matched bearing geometry and surface finish.

This bearing set is ideal for Ford 4.6L SOHC 16-valve engines found in 1996–2010 Mustangs, F-150s, Expeditions, and other modular-platform vehicles. Technicians performing full-engine rebuilds, crank rework, or bottom-end reinforcement rely on King's quality to achieve proper oil pressure and prevent bearing failure under sustained RPM or boost. Installation requires careful honing and torque procedures; consult OEM specifications or a qualified machine shop to confirm final journal sizing and clearances before final assembly.
