Bowtie Chrome 73-86 GM Alternator

The Bowtie Chrome 73-86 GM Alternator is a high-output replacement charging system designed specifically for classic Chevrolet applications from 1973 to 1986. This alternator is ideal for truck owners, muscle car enthusiasts, and restoration specialists who require reliable electrical performance in vintage GM vehicles.

Engineered to meet the power demands of upgraded ignition systems, auxiliary lighting, and modern accessories, this PROFORM unit delivers 70 amps at 12 volts with an internal voltage regulator. The aluminum case construction reduces weight compared to older cast-iron designs, while the single V-belt pulley integrates seamlessly with standard accessory drive configurations found on small-block and big-block Chevrolet engines.

Buyers upgrading fuel injection systems, electric fans, or high-demand stereo installations will appreciate the 70-amp output capacity, which significantly exceeds the original 55-amp output of many vintage alternators. The 3-wire configuration ensures straightforward battery charging and load sensing capabilities, making it a perfect choice for those prioritizing both performance and visual authenticity in their restoration projects.
