Ford SB Alt Bracket Assy

The Ford SB Alt Bracket Assy by March Performance is a precision-engineered alternator mounting solution designed for small block Ford engines running 1G alternators in a mid-mount configuration. This passenger-side bracket assembly replaces worn or damaged factory mounts and is essential for builders and restorers seeking reliable electrical system support in custom engine swaps, hot rod builds, and performance applications. The mid-mount design with water pump integration allows flexible alternator placement while maintaining proper belt tension and engine bay geometry.

Constructed from durable aluminum and finished with a clear powder coat, this bracket resists corrosion and withstands the vibration and thermal cycling inherent to performance engines. The aluminum construction keeps weight minimal—1.9 pounds—while the clear powder coat preserves the material's natural finish for a clean engine bay appearance. The water pump mount integration is a critical feature for small block Ford installations, allowing the bracket to tie directly into the cooling system while securing the alternator, reducing the number of separate mounting points required and simplifying installation complexity.

This bracket is ideal for engine builders, hot rod enthusiasts, and anyone performing a small block Ford 1G alternator swap or engine bay restoration. Proper alternator bracket integrity is critical for maintaining electrical output and preventing belt misalignment, which can reduce alternator efficiency and accelerate belt wear. Installation requires verification of water pump mounting compatibility and belt routing; March Performance brackets are engineered to OEM specifications for small block Ford applications, ensuring fitment with factory and aftermarket engine configurations. Weigh and balance considerations matter in race applications, making the lightweight aluminum design particularly valuable for weight-sensitive builds.
