About us:

We have been in business since 1982.  Our company specializes in starters, alternators, pump motors, winch motors, lift motors, and parts including starter drive bendix, solenoids, armatures, field coils, brushes, regulators, rectifiers, rotors, stators, & bearings for Domestic, and Foreign Car, Truck, Farm, and Industrial Equipment.

Our specialty is the hard to find items.  Just because you can’t find what you are looking for in our listings, does not mean we do not stock it or can’t get it from our suppliers.  We do not have everything we stock listed on the Internet.  Please contact us at 1-800-336-0769 or email with your request.

Very Important: Our solenoids are checked twice.  They are checked at the factory and we also hand test each one on our solenoid tester.  Ask the competition if they hand test each solenoid.
