The secret to achieving full power is the steady voltage output—ideally, between 13.5 and 14.8 volts—you only get from K1500 performance alternators. The crankshaft's mechanical energy becomes electricity through induction, and that's the current your pick-up needs to power up. Before you start installing an alternator for GMC K1500, make sure you have all the equipment to do the job right. Purchase from AutoZone today and enjoy low prices, Same-Day Store Pick-up .
