Tuff Stuff Performance Silver Bullet Stealth Black Alternators
Tuff Stuff Performance Silver Bullet stealth black alternators feature exclusively developed high-tech rotors and stators, built with higher 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 simplifies the installation of these alternators. Featuring a billet aluminum fan and your choice of a serpentine or V-groove pulley to give them over-the-top styling. They also have the highest quality neoprene-sealed bearings for long life. These alternators are finished with an exclusive stealth black powdercoat that is 20 times stronger than ordinary paint.
