OEX Alternator 12V 140A Mitsubishi Style MXA2128

The OEX Alternator MXA2128 is a 12V, 140A passenger alternator supplied in Mitsubishi style and sold individually as each. It is identified by part number MXA2128 and OEM number MXA337, so both references are worth checking when matching the part to the vehicle or to an existing unit.

This alternator sits in the rotating electrical group and is listed as an alternator passenger product. The output rating is 140A at 12V, which is the key specification to compare against the existing alternator before purchase. The listing also carries the note "See Note", so application details should be confirmed carefully before ordering.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, and that they come from ISO9001 certified factories. That matters when you are replacing a charging system component, because correct identification and consistent manufacturing control are both important for a reliable result.

Application and Buying Notes

Before buying, match the existing alternator against MXA2128 and cross-check the OEM number MXA337 where possible. The important mechanical and electrical checks are the 12V system and the 140A output rating, because those two details need to align with the vehicle’s charging system requirements and the replacement unit already fitted.

The fitment preview points to HOLDEN COMMODORE applications, including 2005, 2006 and 2007 models, but the alternator is still sold with a "See Note" warning. That means the safest approach is to verify the vehicle details, the mounting style, and any application notes against the original part before you commit to purchase.

If you are replacing a worn or noisy alternator, compare the unit physically as well as by part number. Belt alignment, connector arrangement and mounting points are the usual checks to complete on a Mitsubishi style alternator, and those checks should be done alongside the 12V 140A specification so the replacement is suitable for 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 MXA2128 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.

Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator passenger in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HOLDEN COMMODORE, HOLDEN COMMODORE 2005, HOLDEN COMMODORE 2006, HOLDEN COMMODORE 2007. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility using part number MXA2128, OEM number MXA337, the 12V 140A rating, and the vehicle application details before ordering. The listing includes HOLDEN and HOLDEN COMMODORE references, but the final match should always be checked against the vehicle and the existing alternator.
