OEX Alternator 12V 130A Denso Style High Output DXA4174HO

The OEX DXA4174HO is a new 12V alternator with a 130A power rating, built in a Denso style and described as a high output unit. It is listed for Isuzu D-MAX and MU-X CRDi 3.0L 4JJ1 applications built from 06/16 to 06/19, and it replaces an original 90A alternator with a higher 130A output.

This alternator uses an internal regulator, a single-leg mount, a 7 groove pulley, and a 160mm mount centre to centre measurement. The mounting details also include a 58mm mount leg thickness, a 10mm pivot hole diameter, and an M8x1.25 adjusting hole, so matching the physical layout matters as much as matching the electrical rating.

The unit is supplied with cable and fuse included for the upgrade, which is a useful detail when changing from the original 90A arrangement to the higher output 130A setup. It weighs 5.04kg and is supplied new, not remanufactured, with OEX part number DXA4174HO.

Application and Buying Notes

This alternator is intended for Isuzu D-MAX and MU-X CRDi 3.0L 4JJ1 vehicles built from 06/16 to 06/19, but the listing also notes there are two identical-looking alternators with different regulator functions. That makes confirmation of the OE number important, especially when the vehicle may have been fitted with more than one charging system variation.

The electrical upgrade is from 90A to 130A, so the higher output is a key point when replacing the original unit. The included cable and fuse are specifically noted for the upgrade, which matters if you are changing from the factory 90A arrangement and want the installation parts that go with the higher current specification.

Before buying, compare the mounting dimensions as well as the application. The single-leg mount, 160mm mount centre to centre, 58mm mount leg thickness, 10mm pivot hole, M8x1.25 adjusting hole, and 7 groove pulley all need to line up with the vehicle’s existing setup. These are the practical checks that help avoid a mismatch when the alternator body looks similar to another version.

Because this unit is new and uses an internal regulator, it should be matched carefully to the correct vehicle and charging system arrangement rather than chosen only by appearance. The part number DXA4174HO, the Denso style description, and the 12V 130A specification are the clearest reference points when confirming the correct replacement.

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 DXA4174HO 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.

Additional published details for cross-checking include Weight 5.04kg, Product Group 1 ROTATING ELECTRICAL, Part No. DXA4174HO, Brand OEX, Description OEX Alternator 12V 130A Denso Style (High Output) Suits Only 06/16 to 06/19, Adjusting Hole Diameter M8x1.25, Pin Code IR234, Power Rating (Amp) 130, Pulley Section 7 Groove, Suits Unit Make Denso.

OEX Alternator 12V 130A Denso Style (High Output) Suits Only 06/16 to 06/19. Part number DXA4174HO 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 DXA4174HO, 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.

Compatibility note: Confirm fitment by part number DXA4174HO, OE number, build date, and the listed mounting and pulley details before ordering. Two similar-looking alternators can have different regulator functions, so the vehicle application and OE match should be checked carefully.
