most GM trucks and SUV's were rated at either 100-105 Amps, or 145 Amps,
and the small case alternators only made 70 amps at idle! The AD275SP
will make more output at idle, 185 Amps,plus at crusing
ANY of the stock alternators used on GM trucks and SUV's make at full
output! With this High Output alternator you are gaining an incredible
