The Aeroflow high output alternator range offers a solution to the inadequate alternator that comes from the factory on many performance vehicles. Especially when it comes time for modifications and power adders with extra electrics on board. Even mild performance builds will typically consume more amperage than what the stock alternator can provide. These alternators help to provide more amperage across the RPM range. All feature a larger 3 diameter pulley for higher revving engines. The great feature with these alternators is these units will bolt directly in place of the OEM alternator. All alternators are finished in a stealth black finish.
