This is a complete low-mount alternator conversion kit for small block Chevy engines. It pairs a 100-amp CS121 alternator in an aluminum case with the bracket, belt and pulleys needed to mount it low on the driver or passenger side of the block. It suits builders replacing a weak factory alternator or adding charging capacity to a carbureted or swapped SBC. Compared with piecing a swap together from junkyard parts, the matched bracket and pulleys remove guesswork, though the 100-amp output is modest next to high-output units sold for winches and big audio systems.
