GMC Sierra 3500 HD Alternator

Great cars and trucks like your Sierra 3500 HD need great parts.

Obviously, you bought your Sierra 3500 HD because you understood you would be getting horsepower and great value both rolled up into one automobile. The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles these days. GMC vehicle enthusiasts have come to expect a certain level of dependability when driving their Sierra 3500 HD around town. When your GMC Sierra 3500 HD left the factory, it was destined for a driver who prioritizes longevity in their automobile.

Don't go too long without fixing your Alternator... here's why.

There are some electrical parts that your engine just couldn't work properly without. Your GMC Sierra 3500 HD alternator has a pulley that spins as the crankshaft spins because they are both connected by a drive belt. Inside that alternator, a constant supply of current for your car or truck is generated as a pair of metal claws and brushes spin around a coil; creating a powerful electromagnetic field. The energy from your alternator continuously charges the battery, and at the same time distributes current to the vehicle's lighting systems, HVAC system, and more on your GMC Sierra 3500 HD.
