Description

All Tuff Stuff alternators are hand built in Cleveland, Ohio and are tested to meet or exceed OEM specifications. They are made from 100% new components and carry a one year limited warranty. Tuff Stuff has alternator applications for virtually all muscle cars, hot rods, customs and light trucks in just about every finish imaginable. Available in chrome plated, polished aluminum, powder coated and plain as cast finishes. All alternators are for 12 volt, negative ground systems, except where noted. Tuff Stuff's Chrome Alternators combine reliable amperage with a show-quality appearance. They are high-quality, direct OE replacements that provide the power needed to run your vehicle's accessories and plenty of charging at low RPMs. They feature heavy-duty copper wound coils and spike-resistant diodes to keep the voltage output constant and safe. The chrome finish is perfect for any engine bay on muscle cars, hot rods, show cars, custom trucks, and daily drivers.
