Can you tell the difference? Most chrome alternators look nearly the same, and that's why what's on the inside is so critical. Reliability starts with how it's made. Choosing PROFORM means choosing alternators with components produced by highly specialized machines, assembled by highly trained personnel using dedicated jigs and equipment, with everything 100% new for maximum longevity and optimum performance. After assembly each alternator is individually tested at the factory. Finally, it's boxed with a quality assurance graph that documents the specific unit's output performance. We do the testing, not you! And PROFORM proves it!
