GM Alternator LS 175Amp Black

The GM Alternator LS 175Amp Black by TUFF-STUFF is designed for high-output electrical demands in LS-engine swaps, restorations, and performance builds where factory charging capacity is insufficient. This alternator provides reliable power generation for upgraded ignition systems, fuel injection controllers, and aftermarket electronics that exceed OEM specifications.

Engineered with a compact, bolt-on design, this alternator fits LS-engine bays without extensive modifications. The black powder-coat finish resists corrosion and complements modern engine bay aesthetics, while the internal voltage regulator maintains stable output across varying RPM ranges and load conditions.

Ideal for LS1, LS2, LS3, and LS9 engine swaps into vintage Chevy, Pontiac, Olds, and Buick platforms, this alternator ensures your battery remains charged under all driving conditions. Installation typically involves standard serpentine belt routing and OEM-style connector compatibility, making it a practical choice for both classic and modern performance builds.
