GM CS121 120-Amp Alternator (V-Belt, Side Post) by Tuff Stuff®
All-new parts, copper-wound coils and spike-resistant diodes support the charging system.
This Tuff Stuff® alternator is built with new components, heavy-duty copper windings and spike-resistant diodes. Each assembly is hand built and tested for charging performance. The CS121-style housing uses an internal voltage regulator. The battery-output terminal is at the side of the housing. The single-groove V-belt pulley must match the accessory drive. Verify case mounting, terminal clearance and belt alignment before installation.
