March Performance Ford 351C Ultra Serpentine Conversion Pulley Kits
March Performance Ford 351C Ultra Serpentine conversion pulley kits are premium engine upgrades designed to eliminate belt slip, throwing, and alignment issues common with classic V-belt setups on 351 Cleveland engines. The base setup acts as an alternator-only conversion, allowing you to efficiently run accessories on a sleek, modern 6-rib serpentine belt.
Additional details:
* Material and Build: Precision CNC-machined from solid 6061-T6 billet aluminum. This guarantees high strength and perfect belt alignment while remaining lightweight
* Maintenance-Free Finish: The pulleys and brackets are treated with a powdercoat finish, meaning you never have to polish hard-to-reach aluminum surfaces to keep them looking new
* Included Components (Base Kit): Typically includes a crankshaft pulley, water pump pulley, alternator pulley with fan and nose cover, an alternator bracket, and heavy-duty Grade 8 mounting hardware
* Engine Requirements: Generally designed to work with a 1969 or later 11-bolt water pump (standard rotation) and a 1968 or later 4-bolt balancer
