OEX Alternator 12V 120A Denso Style DXA433HO

The OEX Alternator DXA433HO is a 12V, 120A unit in Denso style, supplied new and listed with an internal regulator. It is identified as part number DXA433HO and is specified with a fixed pulley, AA pulley section, and clockwise rotation.

This alternator is described as an upgrade from an original 110A unit to 120A high output, with cable and fuse included for the upgrade. The unit is shown as suitable for Denso applications and is listed for Toyota LandCruiser 4.2L 1HD use.

For buyers replacing a charging system component, the important checks here are the 12V system voltage, 120A output rating, single leg alternator mount, 165mm centre-to-centre mount spacing, and the M8x1.25 adjusting hole. Those details matter when comparing the old unit to the replacement.

The listed weight is 6.08kg and the pulley outside diameter is 76mm. The unit is a rotating electrical component sold each, with a 3yr passenger / 1yr commercial warranty listed for the part.

Application and Buying Notes

Before ordering, compare the replacement unit against the part number DXA433HO, the Denso style casing, and the mounting dimensions. The key physical checks are the single leg alternator mount, 165mm mount centre-to-centre, 58mm mount leg thickness, 10mm pivot hole, and M8x1.25 adjusting hole.

The electrical side also needs to match the vehicle. This alternator is 12V with a 120A output and an internal regulator, so it is intended to replace a compatible 12V charging system rather than a different regulator setup or output level.

If you are changing over from an original 110A alternator, this unit is listed as a 120A high output upgrade. The included cable and fuse are relevant to that upgrade, but they should still be checked against the vehicle’s existing wiring and installation requirements before fitting.

Pulley details are another important cross-check. This unit uses a fixed pulley with AA section and a 76mm outside diameter, so the belt and pulley arrangement should be compared carefully with the vehicle already in service.

The supplied fitment list references Toyota LandCruiser applications, including LandCruiser 4.2L 1HD. As with any alternator purchase, the safest approach is to confirm the part number, mount style, pulley configuration, and charging system details on the existing unit before completing the order.

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 DXA433HO 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.
