Whether it’s their design, the engineering that goes into them or the rigorous testing that they undergo, ACDelco starters and alternators represent an appealing choice for discerning consumers.

Sold as GM Genuine Original Equipment (OE) and ACDelco Gold parts, these new and remanufactured starters and alternators offer variety, validation and great reliability and durability.

New OE starters and alternators feature 100-percent new components and are manufactured to be an exact replacement for the parts that came with the new vehicle.

More than 250 part numbers cover light-, medium- and heavy-duty applications, and they all undergo rigorous testing ― particularly with start/stop technology. All OE starters and alternators are backed by a competitive limited warranty.*

“ACDelco Gold alternators and starters are backed by GM OE quality processes and an ACDelco [limited] warranty,* and may be a cost-effective alternative for your business,” says Tiffany Jeffries, Rotating Electrical Product Manager.

New ACDelco Gold starters are thoroughly tested for solenoid contact life as well as coil balance and pull strength, and drive gears and clutches are assembled to tight specifications. With new ACDelco Gold starters and alternators, all dimensions, key mounting surfaces and contact points are gauged and measured for fit. All parts boast completely new components, with more than 550 SKUs comprising an application mix of 35 percent GM/65 percent non-GM.

ACDelco Gold Remanufactured starters feature new brushes, bearings, bushings and solenoid contacts on all parts. The Remanufactured Gold alternators also include new brushes and bearings, and new regulators on many of the top-selling units. The rotors and stators are electronically tested and are sealed by a secondary insulating coating. More than 2,700 SKUs with an application mix of 20 percent GM and 80 percent non-GM make up the remanufactured offering.
