    Holley’s line of premium alternators redefines the capabilities of what was once thought possible from compact alternators. These alternators are specially designed to tolerate 30% higher RPMs than conventional OEM full-sized alternators of the same application. Every component inside and out was redesigned to allow a more efficient output in a compact housing. Not only do they produce a higher output as well as being smaller and lighter than the competition, these alternators are designed to work with any Holley front-drive accessory bracket.

    In addition to the performance gains, these alternators were crafted with an attention to detail that make them stand out against the competition. The entire outer-housing on each premium alternator is crafted entirely from aluminum and has been meticulously sculpted for a smooth exterior that easily polishes clean. Alternators are available in natural cast, polished and black finishes for some of the most popular applications.


    • 150 Amp max output
    • Ideal when power output, size and clearance matter
    • Smaller & lighter than comparable large-case alternators
    • Smooth sculpted all-aluminum housing
    • Works with all Holley accessory brackets
