The New XT-Series Alternator family features a state-of-the-art, braided stator wire design to generate exceptional output in the smallest possible area. The XT-Series produces slightly more power than the previous AT-Series 165A design and operates 5-10C cooler. In addition, Balmar has added Balmar's Smart Ready0 internal regulator technology to provide an additional level of fault tolerance for cruising boaters. Available XT-Series mounting styles have also expanded to include the "Vortec" 9Si design found on many GM gasoline engines.


XT-Series Alternators may require a Tachometer Signal Stabilizer, if your current Tachometer is not adjustable.

This is an XT Series Alternator, with 170A, 12V. It has a Vortec Mount, a K6 Serpentine Pully and is an Isolated Ground Termination.

Mounting Options Below:
GM-Style Mounting; Typical for GM-Block (Chevy) 5.0L, 5.7L, 6.2L Engines

*NOTE* - This is the XT Series Alternator which ends in IG. IG stands for Isolated Ground Termination, meaning the ground is isolated from the case of of the alternator. This type of grounding should produce less electrical noise on the system.
