    GM has offered several series of alternators over the years, each time taking a step up in performance. The great thing about these alternators and aftermarket brackets is that for the most part they are interchangeable. Starting with the externally regulated 10dn alternator of the 1960s and moving all the way to the CS130D alternator of late, aftermarket brackets with rod end tensioners will interchange. The 2" mounting foot width is common to all of them and the 6.61" bolt spacing is common (except the CS130D has 7.24" bolt spacing, which many brackets accommodate). Race Prepped Alternators feature a balanced rotor for high rpm applications. .

    Features:
  • Excellent Idle Amperage
  • 1 or 3-Wire Operation

    47294 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from NICE! I purchased this for my Ford F100. I was replacing a Tuff Stuff one wire so I was already setup for the GM style. I did have to make a spacer to make it work but it was a fraction of the price of the Ford style and looks and works great. You can't beat the price or delivery from Jegs either. I could not be more pleased with Powermaster and Jegs.

    Does Powermaster offer a warranty with this alternator?

    Asked by: WallyBGoode
    Powermaster warrants its products to be free from defects in material and workmanship for one year from the date of purchase. Products used for racing and car audio competition are only warranted up to the time of installation to be free from defects. No warranty exists after installation.
