Description

A Tuff Stuff Performance high-amp output factory cast-plus alternator is just what every ride needs. These units produce the most power at idle to keep your battery fully charged at all times. Tuff Stuff products are hand-built with the best bearings, diodes, and copper windings available; and the cast-plus finish is applied in the company's Cleveland, Ohio factories. This leaves a natural cast look but offers extreme durability from pitting. The alternators are available in a variety of amperages, case and pulley styles for fitment on thousands of specific vehicle applications.
