Genuine Products Alternator 12V 140A Mitsubishi MXA337

The Genuine Products alternator listed here is a new 12V unit rated at 140A, supplied as part number MXA337. It is described as a Mitsubishi unit and uses a clutch pulley with 6 grooves, so it needs to match the vehicle’s existing electrical and belt setup before purchase.

Key mounting details include a single leg alternator mount, 140mm mount centre to centre, 51mm mount leg thickness, and 10mm pivot and adjusting holes. Those measurements are important because alternators may look similar but still differ in fit, alignment, and bracket spacing.

This unit uses a Field Control Unit regulator type and a clockwise rotation. It weighs 6.6kg and is sold individually as each. The stated warranty is one year.

For buyers comparing replacements, the most useful identifiers are MXA337, Mitsubishi application, 12V, 140A, 6 groove clutch pulley, and the mounting dimensions. Matching those details against the removed alternator is the safest way to confirm you are ordering the correct part.

Application and Buying Notes

Before buying, compare the removed alternator with MXA337 and check the critical measurements: 12V, 140A, 6 groove clutch pulley, single leg mount, 140mm mount centre to centre, and 10mm pivot and adjusting holes. These details are the practical checks that determine whether the unit will bolt up and work correctly in the existing charging system.

The regulator type is listed as Field Control Unit, which is another item to verify against the original part. Alternators are often confused by appearance alone, but the pulley type, rotation direction, and mount leg thickness of 51mm can be enough to separate one application from another.

This alternator is a new unit and weighs 6.6kg, so it is intended as a complete replacement rather than a repaired core. If the vehicle has been modified, or if the existing belt system has been changed, match the pulley section and outside diameter of 57mm carefully before purchasing.

The fitment data supplied includes Holden and HSV applications, but those listings are only useful when they line up with the vehicle’s exact build and the original alternator details. A matching make name alone is not enough to confirm suitability, especially on electrical components where several versions can exist within the same model range.

If you are replacing a failed alternator, the safest approach is to compare the part number MXA337, the Mitsubishi unit make, and the mounting and pulley measurements side by side with the old unit. That reduces the chance of ordering a part that looks close but differs in mounting or charging configuration.

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 MXA337 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.
