Jaylec Black Series Performance Alternator  138A - Self Exciting GM

The Black Series is an expanding range of high performance alternators designed for use on performance vehicles.

Made for vehicles that demand more than what O.E. manufacturer alternators can offer. Built to a high standard where reliability and performance are key, with the alternators designed specifically for vehicles that demand more than what the OE alternator offered – higher output (amperage) at lower cut-in speeds.

Intended to run high-demand components at idle, such as dual thermos-fans, injection systems, air conditioning, electric steering, monitoring systems, upgraded lighting systems and winches, while maintaining the battery at the desired levels.

With a rigorous design and testing phase, combined with efficient cooling fans and the highest quality bearings ensure that they can replace and outperform the most popular units in the market today.

All Black Series alternators have been amperage rated Hot and Cold.
