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

Rating: (see review/s)

"The alternator was the right one with the exception that it didnt truly fit the engine properly....the back bolt position was wrong and thus had to be modified to fit. Given ALL the specs required this should NOT HAPPEN; and given I bought the more expensive OEM part that should have been EXACT...BUT WASNT. cLOSE IS not good enough WHEN DEALING WITH VITAL ENGINE PARTS so more care and attention is really in order here...." posted by: videojoe on June 17, 2013
