OEX Alternator 12V 180A Denso Style DXA4152

The OEX Alternator DXA4152 is a 12V, 180A unit built in a Denso style configuration. It is listed as a new alternator with an internal regulator, a 6 groove pulley, and a quad leg mount, so it suits buyers who need those specific mounting and electrical details matched before ordering.

Key dimensions include 45mm inside mounting legs, a 139mm centre-to-centre mount, a 54mm pulley outside diameter, and an M10x1.5 / 11 pivot hole diameter. Those measurements matter because alternators may look similar at a glance but still differ in bracket spacing, pulley setup, or fixing points.

This unit is identified by part number DXA4152 and pin code IR201. The listed application reference is Denso, so the safest approach is to compare the part number, regulator type, mount style, pulley section, and physical dimensions against the existing unit already fitted to the vehicle.

Application and Buying Notes

For this alternator, the most important checks are the part number DXA4152, the Denso style application, and the physical mounting details. The listed 6 groove pulley, quad leg mount, 45mm inside mounting legs, 139mm centre-to-centre spacing, and M10x1.5 / 11 pivot hole diameter need to line up with the unit being replaced.

The 180A output rating is a useful point of comparison when replacing a charging system component, but the alternator still has to match the vehicle’s mounting arrangement and pulley configuration. A different amperage unit or a different pulley count can create installation problems even when the alternator appears similar.

Because alternators are matched by a combination of electrical and mechanical details, it is best to confirm the existing unit’s label, mounting ears, pulley section, regulator arrangement, and dimensions before purchase. The pin code IR201 and the Denso application reference are additional checkpoints that help narrow the correct replacement.

If the vehicle has already been modified, or if the original alternator has been replaced before, compare the fitted unit carefully rather than relying only on model year or general vehicle description. The safer method is to check the actual alternator on the vehicle and confirm it against the measurements and identifiers listed here.

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 DXA4152 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.

For part number DXA4152, 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 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by checking the part number DXA4152, the Denso style application, and the physical details including 12V, 180A, 6 groove pulley, quad leg mount, 45mm inside mounting legs, 139mm mount centre-to-centre, and M10x1.5 / 11 pivot hole diameter before ordering.
