Steel Crank Hub BBF 390-460

The Steel Crank Hub BBF 390-460 from Blower Drive Service is a precision-engineered component designed for big-block Ford engine builders and supercharger enthusiasts running 390, 427, or 460 cubic-inch mills. This crank hub serves as the critical interface between your engine's crankshaft and blower drive system, allowing you to reliably transmit power from the crank to your supercharger or accessory drive.

Manufactured from high-quality steel, the BBF 390-460 hub is built to withstand the extreme rotational forces and torsional stress inherent in forced-induction and belt-driven accessory applications. The steel construction ensures durability and thermal stability under sustained high-RPM operation—critical when you're running a high-displacement big-block at aggressive boost levels or continuous belt loads. Blower Drive Service's precision manufacturing tolerances guarantee proper concentricity and fit, eliminating runout and vibration that would compromise your drive system.

This crank hub is essential for anyone installing or refreshing a blower drive, serpentine accessory system, or custom belt-drive configuration on a big-block Ford engine. Whether you're building a street-strip engine, vintage hot rod, or high-performance race motor, a quality crank hub is non-negotiable for safe, consistent operation.
