ACDelco’s Professional Remanufactured Alternators are the ideal high quality replacement for many vehicles on the road today. ACDelco’s Professional Remanufactured Alternators use high-quality bearings with high-temp lube and double-lipped rubber seals. Rotors and stators are electronically tested and then sealed with secondary insulating coating. Remanufacturing alternators is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear and failure with new components. Damaged and obsolete parts are replaced and are 100% end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing also benefits the environment by returning components back into service rather than processing as scrap or simply disposing of them. These premium aftermarket reman alternators are manufactured to fit a wide range of vehicles and will provide the same performance, durability, and service life you expect from ACDelco.

Product Features:

• Remanufactured using consistent quality processes; not just rebuilt
• Alternators use high-quality bearings with high-temp lube and double-lipped rubber seals, reducing friction, vibration, and noise
• Rotors and stators are electronically tested and then sealed with secondary insulating coating to help prevent shorts
• All units are 100% performance tested and inspected to ensure they meet ACDelco quality design and component specifications
