The JS Alternators CS130 is a hairpin (6-phase) high-output alternator built for 1987-1995 Chevy C1500 pickups and some aftermarket accessory drives. Hairpin winding produces more output at idle and runs more efficiently than a conventional alternator, which matters for car audio, marine and racing builds with heavy electrical demand. It uses premium bearings rated for high engine rpm and a dual-plate rectifier with 12 heavy-duty diodes for better cooling and heat tolerance. Activation takes one wire from the included pigtail to any ignition-switched 12V+ source, and the smaller pulley means you need a belt half an inch to an inch shorter.

The CS130 High Output Alternator is a hairpin unit, commonly called a 6 phase alternator. It produces more output at idle and is more efficient than a conventional alternator. The CS130 style is commonly used on 1987-1995 Chevy C1500 pickups and some aftermarket accessory drives.
It has premium bearings built to withstand high engine rpm. A dual plate rectifier with 12 heavy duty diodes improves cooling. The hairpin design is built to withstand high heat and high demand in car audio, marine and racing applications.
To activate it, connect a single wire from the provided pigtail to any ignition switched 12V+ source. The alternator then turns on and off with the ignition switch. It comes with a smaller pulley, so it needs a belt that is 1/2 inch to 1 inch shorter. Motor swap applications come with a 45 mm pulley and also need a belt 1/2 inch to 1 inch shorter.
