OEX Alternator 12V 130A Denso Style DXA4022

The OEX Alternator DXA4022 is a 12V, 130A unit built in a Denso style and supplied as a new alternator. It is designed with a single leg mount, 6 groove pulley, and internal regulator, so matching the physical layout and connector style is just as important as matching the voltage and output.

This unit suits a Denso application and uses a connector with small pins and no divider. If the vehicle uses standard pins with a divider, the alternative references noted for that connector style are DXA4014 or DXA576. The mounting details also matter here: mount leg thickness is 46mm, mount centre to centre is 168mm, and the adjusting hole diameter is 8mm.

OEX states that its products are sourced from leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified for engineering, testing, and quality control procedures. This alternator is backed by a 3 year passenger / 1 year commercial warranty, which gives buyers a clear warranty distinction depending on how the vehicle is used.

Application and Buying Notes

Before ordering, compare the part number DXA4022 with the alternator already fitted to the vehicle, then check the physical mounting details: single leg mount, 46mm mount leg thickness, 168mm mount centre to centre, and an 8mm adjusting hole. Those measurements are the practical checks that help confirm whether the unit will line up correctly in the bracket and belt system.

Connector style is another critical point on this alternator. The supplied note states it has small pins with no divider, and that vehicles requiring standard pins with a divider should instead use DXA4014 or DXA576. That makes the connector and plug layout just as important as the electrical rating when matching the replacement unit.

The 12V and 130A specification tells you the electrical capacity of the alternator, while the 6 groove pulley and 65mm pulley outside diameter help confirm belt compatibility and physical fit. The unit is listed as new, weighs 5.68kg, and uses an internal regulator, so it is best matched by verifying the existing alternator’s regulator arrangement and pulley configuration before purchase.

Warranty terms are different for passenger and commercial use, with 3 years for passenger and 1 year for commercial. If the vehicle is used in a commercial setting, that shorter warranty period should be considered before fitting. Keeping the old unit for comparison until the replacement is confirmed is often the safest approach when dealing with alternators that have multiple connector and mounting variants.

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 DXA4022 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 130A Denso Style. Part number DXA4022 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 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4022, 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 checking the vehicle application, alternator part number, connector style, pulley section, and mounting measurements against the existing unit before ordering. If the vehicle uses standard pins with a divider, this is not the same connector style and DXA4014 or DXA576 are the listed alternatives.
