Customer Review: (see review/s)
  • This product came packaged with care from an ISO that is known for quality. Everything is new and was simple to mount. Comes with new pulley and backed by a lifetime warranty with road breakdown for battery jump off. First impressions makes the difference when ready to buy again. I feel I got more than I thought I was paying for.DJ

Powermaster High-Performance Alternators for GM Engines

POWERMASTER HIGH-PERFORMANCE ALTERNATORS FOR GM ENGINES

Making upgrades to your classic GM vehicle but you want to retain the original look? Reinforce your vehicle’s electrical system with a Powermaster High-Performance Alternator to keep the classic GM 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 the redline. Powermaster is best known as a specialist performance manufacturer, providing high performance alternators and starters primarily for American cars, trucks and SUVs.

  • Manufactured in the U.S.A
  • Perfect for classic GM restorations
  • Popular GM cases such as CS130, 12SI and 17SI and many others are all made by Powermaster
  • Excellent idle output
  • Choose from five finishes chrome, satin, natural, black or polished
  • Choice of 1-wire or original 3-wire style installations
  • Every Powermaster alternator is tested before it leaves the factory, (certificate of testing included)
