Main Bearing Set Coated BBF 429/460

The ACL BEARINGS Main Bearing Set Coated BBF 429/460 is specifically engineered for Big Block Ford engines, providing precision-machined bearing surfaces that ensure superior load-carrying capacity. This bearing set is ideal for mechanics and engine builders who prioritize reliability in high-performance builds and restorations. Proper main bearings are essential for a stable and long-lasting bottom end, especially in performance applications.

ACL's proprietary coating technology enhances wear resistance and reduces friction between the crankshaft journals and bearing surfaces. This is critical for protecting against spun bearings and catastrophic engine failure. The coated design effectively distributes loads across the bearing shell and maintains proper oil film thickness, even under peak combustion pressures.

Engine builders and dedicated enthusiasts choose this bearing set for complete bottom-end assemblies and performance restorations, where the 429/460 Big Block Ford platform demands high-quality components. The precision manufacturing ensures tight tolerances that accommodate both stock and modified engine builds, making it a reliable choice for serious automotive applications.
