The Tuff Stuff CS121 series 7937 mini alternators feature heavy duty copper wound coils, spike-resistant diodes, an internal voltage regulator and an external cooling fan for long life dependability.

The side post terminal simplifies installation and provides nearly 1 inch of extra rear clearance, making this alternator series perfect for high horsepower muscle cars, hot rods, show cars, customs and daily drivers alike.
