The New XT-Series 170A Alternator family features a state-of-theart, braided wire stator 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 50-100C 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 been 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, 170A, 12V, with a Spindle Mount (Single Foot), 1-2" Mounting Options, with the K6 Serpentine Pulley, with Isolated Ground Termination.
