Description
The right part.
Down to the detail.
New aftermarket alternator for Ford Ranger PX and PX II ute/cab-chassis applications with the 3.2L P5-AT five-cylinder diesel engine, 11/2011–06/2018. Reference AB39-10300-AF. This is the 12V-system, 110A type with a seven-groove pulley and the pictured RP36 connector profile. Match the original reference, connector, pulley and mounting arrangement before ordering; the model badge alone is insufficient. One alternator with pulley is included. Vehicle wiring, drive belt and installation hardware are not claimed as included. This listing is restricted to the stated 3.2L PX/PX II application; it does not cover the 2.0L Bi-Turbo, next-generation Ranger or every charging-system variant by assumption. Send your VIN, build month, engine details and photographs of the original alternator for a fitment check.
Reference AB39-10300-AF; compare the original number, connector, mounting points and pulley. Send our team your exact model, build date and a photo of the original part if you need a fitment check.
