Making upgrades to your classic Ford but you want to retain the original look? Reinforce your vehicle's electrical system with a Powermaster High-Performance Alternator and keep the classic Ford look under hood but with reliable state-of-the-art innards. If your vehicle is equipped with a powerful aftermarket audio system, your stock alternator will be underpowered and overburdened at times by trying to supply power to both electronics and your engine. This causes your vehicle's lights to dim and battery to drain. Installing a Powermaster High-Performance Alternator on a modified engine will provide the extra electrical power needed, starting from idle all the way to redline. Powermaster is best known as a specialist performance manufacturer, providing high performance alternators and starters primarily for American cars, trucks and SUVs.
