DENSO 210-5357 First Time Fit Remanufactured Alternator - 110A 12V

The DENSO 210-5357 is a First Time Fit remanufactured alternator delivering 110 amps at 12 volts, engineered to OE standards for a reliable, drop-in replacement. Featuring an internal voltage regulator, internal cooling fan, and clockwise rotation, this unit is sold without pulley and is designed to meet the exact mounting and electrical specifications of the original equipment component it replaces.

Every remanufactured DENSO alternator undergoes a rigorous rebuilding and testing process. Stators and rectifiers are tested to 300 volts, while rotors are subjected to 600 volts to verify reliable output under real-world conditions. Rotor slip rings are precision-buffed to an 8-micron surface finish with runout held to 20 microns, minimizing brush wear over the service life of the unit. Bearings are validated to OE standards and packed with premium OE-grade lubricants for long-term durability.
