Alternator Bracket BBC Short Water Pump Black

The Alternator Bracket BBC Short Water Pump Black from TUFF-STUFF is engineered for hot rodders, engine builders, and mechanics tackling big block Chevy installations where space and mounting options demand precision engineering. This driver-side, high-mount bracket solves a critical problem in compact engine bay layouts: integrating a secondary pulley system while maintaining alternator output and belt tension without interference. Built for use with short water pump configurations on GM 10SI, 12SI, and CS130 alternators, this bracket becomes essential when factory mounting points conflict with modern cooling systems or custom headers.

Constructed from heavy-duty steel and finished with black powder coat for corrosion resistance and a clean engine bay appearance, the alternator bracket weighs 4.55 lbs and measures 5.5 x 5.5 x 10 inches—compact enough for tight installations yet rigid enough to handle the harmonic loads of a big block at sustained RPM. The high-mount design raises the alternator above traditional mounting planes, critical for clearance when short water pump pads are used instead of standard long-pump configurations. Powder coating protects against salt spray, oil mist, and thermal cycling without adding excess material or weight, ensuring years of reliable service in both street and race environments.

This bracket is ideal for builders retrofitting modern alternators into classic big block applications, street rods with custom cooling systems, and performance engines where OEM mounting is impossible or undesirable. Compatibility spans GM 10SI, 12SI, and CS130 alternator families—the industry standard across vintage Chevy powerplants and modern high-output replacements. Installation requires basic mechanical skill and standard hand tools; ensure proper belt tension and clearance verification before final assembly, as high-mount geometry affects serpentine belt angles and idler pulley relationships.
