Tuff Stuff Performance Silver Bullet Alternators
Tuff Stuff Performance Silver Bullet alternators feature high-tech rotors and stators, built with elevated copper and steel content, to deliver the greatest output with the best reliability. Ultra-low cut-in voltage regulators keep the extra amps flowing in low-idle situations, and a real one-wire hookup (most models) simplifies the installation of these alternators. Silver Bullet alternators have a billet aluminum fan and your choice of a serpentine or V-groove pulley to give them over-the-top styling. They also feature the highest quality neoprene-sealed bearings for long life. Order the model recommended for fitment and performance on your specific vehicle.
