Heavy-Duty Truck Alternators
Simply the Best Truck Alternators
DENSO is the largest manufacturer of alternators in the world, with 75+ years of experience as an OE manufacturer, an extensive service network and the best warranty in the market. Combine that with our commitment to quality, innovation and reliability and value, and it’s no wonder why we’ve remained on top. You can feel confident that a DENSO heavy-duty alternator will perform better under rigorous conditions.
In addition to our high-quality, long-lasting, heavy-duty new alternators, DENSO brings the same durability and innovation to our remanufactured units. Because they recycle valuable parts and conserve previous raw materials, they represent both a wallet-friendly and environmentally responsible choice.
As an industry leader, DENSO brings that same unwavering commitment to remanufactured units:
- Stators and rectifiers are tested to 300 volts.
- Rotors are submitted to 600 volts.
- Rotor slip rings are buffed to an 8-micron surface finish.
- Bearings are validated to OE standards and loaded with premium OE-standard lubricants.
And whether new or manufactured, every DENSO alternator is a quality unit.
- Mount properly – the first time – without issues.
- Meet or exceed all manufacturer standards.
- Provide years of reliable service.
