XP Main Bearing Set BBF 429/460

The XP Main Bearing Set BBF 429/460 is engineered for high-performance Big Block Ford engines frequently found in racing and heavy-duty applications. Designed for the 385 series 429 and 460 V8 engines, this set provides the necessary durability to withstand the extreme loads generated by high-output builds. Whether you are building a drag strip competitor or a high-torque towing machine, these bearings are essential for maintaining crankshaft stability and oil film consistency under pressure. This comprehensive set is the ideal choice for enthusiasts looking to buy professional-grade internal components for their Ford powerplant.

These King Bearings feature the XP series tri-metal construction, which incorporates a hardened steel back, a copper-lead intermediate layer, and a patented pMaxBlack overlay. This specific material composition allows the XP Main Bearing Set BBF 429/460 to handle higher cylinder pressures and increased RPM ranges compared to standard replacement parts. Advanced geometric features like Bull's Eye Tolerance ensure precise oil clearance across the entire set, while the enlarged oil holes and full-groove design optimize lubrication delivery to critical engine components. These specifications are vital for preventing premature wear during high-stress operating cycles.

Designed specifically for the Ford 429 and 460 engine platforms, this bearing set is the preferred choice for engine builders seeking to maximize reliability in high-horsepower environments. The XP Main Bearing Set BBF 429/460 is ideal for use with forged or cast crankshafts in applications requiring tighter tolerances and superior fatigue resistance. Reviewing your specific clearance requirements before installation is recommended to ensure proper crush and fitment, guaranteeing your Big Block Ford operates at peak efficiency. This set provides the specialized protection required for high-performance builds that demand more than an OEM-style bearing can offer.
