SB Chevy 305-350 Alterna tor Bracket

The SB Chevy 305-350 alternator bracket is an essential component for small block Chevrolet engine builds where OEM-style charging system integrity matters. Whether you're restoring a classic Chevy, upgrading a street rod, or tuning a performance engine, this passenger-side lower bracket maintains proper alternator alignment and belt tension on long water pump configurations. Built to original equipment specifications, it ensures reliable electrical generation without requiring custom fabrication or aftermarket workarounds that compromise fitment or durability.

Constructed from heavy-duty steel with a chrome finish, the SB Chevy 305-350 alternator bracket resists corrosion and heat cycling while maintaining precise dimensional tolerances necessary for long water pump clearance. The O.E.-style design distributes alternator load evenly across the engine block and accessory drive mounts, reducing vibration and preventing bracket flex under high-output charging demands. At just 0.45 lbs, the compact 3.9 x 0.45 x 8.7-inch bracket integrates seamlessly into tight engine compartments without interference with hoses, belts, or other auxiliaries.

Mechanics and engine builders trust this bracket for small block Chevy applications spanning 305 and 350 cubic-inch displacements, particularly when factory-correct appearance or originality restoration is required. Installation is straightforward using stock bolt patterns and mounting points, making it ideal for restorations, crate engine swaps, and high-performance builds where reliability and authenticity align. The chrome finish adds visual appeal to engine bays while the steel construction guarantees years of trouble-free service under demanding driving conditions.
