Speedmaster 1-673-003-02 Ford SB 289 302 351W Serpentine Belt Drive System Kit Black

The Speedmaster 1-673-003-02 is a complete serpentine belt accessory drive system kit engineered for Ford small block 289, 302, and 351W engines. Designed for street rod, hot rod, and track builds, this all-inclusive kit replaces the factory V-belt system with a modern single-belt serpentine setup, delivering improved reliability, cleaner engine bay aesthetics, and reduced parasitic drag.

The kit is engineered around a high water flow ratio pulley design, ensuring adequate coolant circulation at all RPM ranges. The rigid one-piece bracket assembly provides a solid mounting platform for the alternator, power steering pump, and A/C compressor cover, compatible with any cylinder head or intake manifold configuration.
