Jaylec Black Series Performance Alternator 138A - Self Exciting GM (PART #JYE-BKS-140GM)

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.

Black Series Performance Alternators are designed to support high-demand vehicle electrical systems, including:

• Dual thermo-fans and fuel injection systems
• Air conditioning and electric steering systems
• Monitoring systems and upgraded lighting systems
• Winches and other high-load accessories where supported by the application

They are intended to run high-demand components at idle while maintaining the battery at the desired levels.

With a rigorous design and testing phase, combined with efficient cooling fans and high quality bearings, these alternators can replace and outperform the most popular units in the market today.

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