Main Bearing Set - Ford 4.6L DOHC/SOHC

The Main Bearing Set - Ford 4.6L DOHC/SOHC from KING BEARINGS is engineered for both naturally aspirated and forced-induction builds seeking reliable crankshaft support and minimal wear. Whether you're rebuilding a high-mileage 2-valve or 4-valve modular engine or pushing your platform toward boost, main bearings are the foundation of engine longevity and performance stability. This set replaces OEM bearings that wear under elevated loads, cylinder pressure spikes, and sustained RPM levels typical of street and track applications.

KING BEARINGS are manufactured to strict OEM and aftermarket racing specifications, featuring precision-machined surfaces and optimized clearance tolerances that reduce friction while maintaining film strength under load. The HP0.25 designation indicates a 0.25mm undersize, allowing machinists to achieve proper clearance on crankshafts that have been ground or polished. The bearing material compound and tri-metal construction dissipate heat effectively, preventing hot spots that lead to micro-welding and catastrophic failure in high-performance engines. Proper installation with precise torque specifications and clean oil supply ensures maximum bearing life and consistent oil pressure across all cylinders.

This bearing set is essential for anyone rebuilding a Ford 4.6L modular engine—from stock restorations to turbocharged or supercharged platforms. Mechanics and engine builders working on 1996–2010 Mustang, F-150, and Crown Victoria powerplants will find these bearings compatible with both DOHC and SOHC variants, making them a versatile choice for full-engine overhauls. Always pair bearing installation with a complete oil system flush, fresh filter, and quality break-in oil to ensure proper bearing seat and long-term reliability.
