OEX Alternator 12V 130A Denso Style DXA4120

The OEX Alternator 12V 130A Denso Style, part number DXA4120, is a new 12-volt alternator with a 130 amp power rating. It is listed as a Denso suit unit and uses an internal regulator, making the key matching points the voltage, amperage, mount style and pulley details rather than appearance alone.

This alternator has a quad leg mount with 57mm inside mounting legs, a 179mm mount centre-to-centre measurement, and 11/M10x1.25 pivot and adjusting hole diameters. The pulley is a 6 groove design with a 58mm outside diameter, so matching the drive setup on the vehicle is important before ordering.

OEX notes this alternator range is backed by a reputation for quality and reliability at an aftermarket price, with major manufacturers typically acting as OEM suppliers. The unit is also supported by a 3 year passenger or 1 year commercial warranty, and the unit weight is 6.24kg.

Application and Buying Notes

Check the part number DXA4120 first, then compare the alternator layout against the vehicle fitted unit. On this alternator, the important matching points are the 12V system, 130A output, internal regulator, quad leg mount, 57mm inside mounting legs and 6 groove pulley with a 58mm outside diameter.

The mount dimensions matter just as much as the electrical rating. This unit has a 179mm centre-to-centre mount measurement, with 11/M10x1.25 pivot and adjusting holes. If those dimensions do not line up with the vehicle’s original alternator, it should not be treated as a direct match.

Because the fitment information supplied references Hyundai Santa Fe and Kia Carnival / Grand Carnival applications, it is sensible to verify the exact vehicle build and the existing alternator details before purchase. Matching by vehicle name alone is not enough when the part uses a specific Denso style configuration.

The listed warranty is 3 years for passenger use and 1 year for commercial use. That warranty detail is useful when comparing options, but it does not replace fitment confirmation. The safest approach is to verify the unit make, mount arrangement, pulley groove count and amperage against the original part already on the vehicle.

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 DXA4120 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 DXA4120, 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 compatibility using the DXA4120 part number, the 12V 130A specification, Denso style application, quad leg mount, 6 groove pulley and the vehicle’s original alternator measurements before buying.
