Product Details

Denso reman alternators are rebuilt to OE-level standards using premium cores and precise assembly controls. Critical components such as stators, rectifiers, rotors, slip rings, and bearings are evaluated and finished to support stable charging performance and reduced brush wear. This matters on Ford F-250 Super Duty and Ford F-350 Super Duty trucks, where the charging system must support multiple electronic systems and sustained electrical demand.

This part cross-references BBB Industries 11622 and Bosch AL7677X for the same application. Use part number 210-1221 when verifying replacement needs for the listed Ford Super Duty fitments.
