OEX Alternator 12V 160A Denso Style DXA519HO

The OEX Alternator 12V 160A Denso Style, part number DXA519HO, is a new rotating electrical unit rated at 160 amps for 12-volt systems. It is listed as a Denso-style alternator with an internal regulator and a single leg mount arrangement, which makes the mounting pattern and regulator setup important points to confirm before purchase.

This unit is designed as an upgrade from an original 80A alternator to 160A, and the listing notes cable and fuse are included for the upgrade. It is also identified as suitable for Denso applications, with OEM number DXA519 and pin code IR11, so matching the part number and application details is the safest way to check compatibility.

A specific application is noted for Toyota LandCruiser Prado KZJ120R 3.0L 1KZ. The alternator uses a 73mm pulley outside diameter, AA pulley section, 58mm mount leg thickness, 10mm pivot hole diameter, M8x1.25 adjusting hole diameter, and 165mm mount centre-to-centre measurement. These details matter when checking physical fitment and belt alignment.

Application and Buying Notes

For this alternator, the most important checks are the part number DXA519HO, the OEM number DXA519, and whether the vehicle uses a Denso-style unit with the same mount and pulley arrangement. The alternator is 12V and 160A, so it is intended for systems that can accept that output and the matching internal regulator setup.

Physical dimensions should be checked carefully because alternators can look similar but mount differently. This unit has a single leg mount, 58mm mount leg thickness, 10mm pivot hole diameter, M8x1.25 adjusting hole diameter, 165mm mount centre-to-centre, and a 73mm pulley outside diameter with AA section. Those measurements are the practical comparison points when matching brackets and belt drive alignment.

The listing notes that it is an upgrade from original 80A to 160A and that a battery cable and fuse are included for the upgrade. That can be useful when replacing a lower-output alternator, but the rest of the charging system still needs to suit the application. The note that the L terminal does not drive choke is also worth checking against the vehicle’s wiring before installation.

Because this is a new alternator rather than a remanufactured unit, you are starting with a fresh component. Even so, fitment should still be checked against the vehicle application, regulator type, mount style, and the listed pin code IR11. If any of those do not match, the alternator may not be the correct choice for the job.

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 DXA519HO 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 160A Denso Style. Part number DXA519HO should be checked first. Listed voltage is 12. Listed output rating is 160. 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 AA. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA519HO, 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 160 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Please confirm fitment using the part number DXA519HO, OEM number DXA519, Denso application details, and the listed mounting and pulley measurements before ordering.
