Holley Premium Alternators

With performance engines pushing redlines up higher and higher, alternators are being forced beyond their design. Holley's premium alternators can tolerate 30 percent higher rpms than conventional models. The attention to cosmetic detail on these units is above and beyond what you would expect, too. The entire outside housing has been sculpted for a smooth silhouette that hides the ugly details we typically think of as alternators. If you drag race, autocross, or just hot rod your ride, be assured that Holley premium alternators won't fly apart on you.

Features:

* Available in natural, black, and polished finishes
* Works with all Holley accessory brackets, as well as 4th generation F-body, most 1998 thru 2004 GM trucks, and many other applications
* 150 amp output
* Smaller and lighter than Holley high-amp alternators
* Housings are smoothed to make polishing clean (no buffer cut marks trying to get in tight corners)
* Rear cover is aluminum instead of typical black plastic
* Ideal when size and clearance matter
* Black and polished pulley covers are available on models that don't already include them
* Designed for use with Holley alternator weatherproof pigtails (not included)
