Product Details

Denso reman alternators go through electrical testing of critical components, including stators, rectifiers, and rotors, to verify performance before release. Bearings are validated to OE standards, and rotor slip rings are finished to reduce brush wear and abrasion. The result is a reman alternator designed for modern charging demands and sensitive electronics. Part number 210-5373 is a practical replacement for drivers and technicians servicing Ford Ranger and Mazda B2300 charging systems.

This part cross-references ACDelco 334-2508 and Bosch AL7584X for the same application.
