DENSO 210-1252 Remanufactured Alternator

The DENSO 210-1252 is a remanufactured alternator built to restore OE charging performance to your vehicle. As part of DENSO's First Time Fit line, this alternator is precision-engineered to match original equipment specifications, ensuring proper fit and full compatibility with your vehicle's electrical systems right out of the box.

Every remanufactured DENSO alternator undergoes a rigorous rebuilding process designed to meet or exceed the standards of a brand-new unit. Stators and rectifiers are tested to 300 volts, while rotors are subjected to 600 volts to verify reliable electrical output. Rotor slip rings are precision-buffed to an 8-micron surface finish with runout held to within 20 microns, reducing brush wear and extending service life. Bearings are validated to OE standards and packed with premium OE-grade lubricants for long-lasting, quiet operation.
