OEX Alternator 12V 130A Denso Style High Output DXA4173HO

The OEX DXA4173HO is a new 12V alternator rated at 130A and built in a Denso style high output format. It is listed as a single leg alternator with an internal regulator, 7 groove pulley, 58mm mount leg thickness, and 160mm mount centre to centre.

This unit is intended as an upgrade from the original 90A setup to 130A high output, and the included cable and fuse are provided for the upgrade application. It is specifically listed for Isuzu D-MAX and MU-X CRDi 3.0L 4JJ1 applications within the stated build date range.

There is an important identification point to check before ordering: there are two identical looking alternators with different regulator functions. The correct unit should be confirmed by OE number, and the listed note states suitability from 07/12 to 05/16, while the description states 07/12 to 06/16.

Application and Buying Notes

Before ordering, confirm the part number DXA4173HO and compare the OE number, because two visually similar alternators are noted and they use different regulator functions. The unit is a 12V, 130A alternator with an internal regulator, so the regulator type matters as much as the mounting shape.

The upgrade hardware included with this alternator is a cable and fuse, which suits the high output change from the original 90A arrangement to 130A. If the vehicle has had previous electrical modifications, check the existing charge cable arrangement and fuse setup against the supplied upgrade parts before installation.

Physical checks are just as important as vehicle make and model. Verify the single leg mount, 58mm mount leg thickness, 160mm mount centre to centre, M8x1.25 adjusting hole, 62.5mm pulley outside diameter, and 7 groove pulley section so the alternator matches the mounting and belt setup already on the vehicle.

This alternator is listed for Isuzu D-MAX and MU-X CRDi 3.0L 4JJ1 applications within the stated build date range, but the date note is given as 07/12 to 06/16 in one place and 07/12 to 05/16 in another. That makes confirmation against build date, OE number, and the existing alternator especially important before purchase.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number DXA4173HO helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Alternator 12V 130A Denso Style (High Output) Suits Only 07/12 to 06/16. Part number DXA4173HO should be checked first. Listed voltage is 12. Listed output rating is 130. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4173HO, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include ISUZU D-MAX, ISUZU D-MAX 2012, ISUZU D-MAX 2013, ISUZU D-MAX 2014. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment by checking DXA4173HO, the OE number, regulator type, mounting dimensions, pulley details, and your vehicle build date before ordering. Where the vehicle sits close to the listed date range or has had prior alternator changes, compare the original unit carefully.
