OEX Alternator 12V 80A Denso Style DXA4179

The OEX DXA4179 is a new 12V alternator rated at 80A, built in a Denso style for applications that require a twin leg mount and a 4 groove pulley. It is listed with a 160mm mount centre-to-centre measurement, 41mm inside mounting legs, and an M8x1.25 adjusting hole, so the mounting points can be checked before ordering.

This unit suits Denso units and is supplied as a new rotating electrical component, not a remanufactured exchange part. The pulley outside diameter is 57mm, and the unit weight is 4.56kg, both of which are useful reference points when comparing the replacement against the original alternator already fitted to the vehicle.

OEX lists this alternator under part number DXA4179, with a warranty of 3 years for passenger use and 1 year for commercial use. For buyers matching a charging-system replacement, the important checks are the 12V system requirement, 80A output, twin leg mounting, and the 4 groove pulley arrangement.

Application and Buying Notes

Alternators need to match the vehicle’s electrical system and physical mounting layout, so the key points here are 12V, 80A, twin leg mounting, and the 4 groove pulley. If any of those details differ from the unit already fitted, the replacement may not line up correctly or may not be the right charging specification for the application.

The listed dimensions are there to help you compare like for like. A 160mm mount centre-to-centre measurement, 41mm inside mounting legs, and an M8x1.25 adjusting hole are all practical checks when confirming a replacement alternator. The 57mm pulley outside diameter and 4 groove belt arrangement should also be matched carefully, as pulley and belt setup are common reasons a unit is rejected during installation.

This alternator is supplied new and carries OEX warranty cover of 3 years for passenger use and 1 year for commercial use. For commercial vehicles in particular, it is sensible to confirm the duty cycle, mount style, and belt configuration before fitting, because the part number DXA4179 is only useful when it lines up with the correct application and physical measurements.

Where vehicle fitment is not already confirmed by your registration or VIN lookup, compare the original alternator directly against the dimensions and mounting style listed here. That is the safest way to avoid guesswork, especially when working with Denso style charging systems where similar looking units can differ in bracket layout, pulley section, or adjuster size.

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 DXA4179 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 80A Denso Style. Part number DXA4179 should be checked first. Listed voltage is 12. Listed output rating is 80. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Pulley configuration is 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4179, 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 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by matching part number DXA4179, Denso style application details, 12V system, 80A output, twin leg mount, 160mm mount centre-to-centre, 41mm inside mounting legs, M8x1.25 adjusting hole, and 4 groove pulley setup before ordering.
