Description

Hairpin units are commonly called 6 phase. They produce more output at idle and are more efficient than a conventional alternator. JS Alternators hairpin units feature premium bearings to withstand high engine rpm and utilize dual plate rectifier with 12 heavy duty diodes for improved cooling. Hairpin Units are a more reliable alternator to withstand high heat, high demand for car audio, marine, and racing applications.

This alternator is a direct fit for your LS engine swap and makes for an easy installation. To activate the alternator, you only need to connect a single wire from the provided pigtail to any ignition switched 12V+ source. This allows the alternator to turn on and off with the ignition switch. These units come with a smaller pulley which requires installing a half inch to an inch shorter belt.

All Motor Swap Applications will come with a 45 mm. pulley and will require installing a 1/2 inch - 1 inch shorter belt.
