OEX Alternator 12V 90A Denso Style DXA4174

The OEX DXA4174 is a new 12V alternator rated at 90A and designed in a Denso style with a single leg mount. It suits vehicles built from 06/16 to 06/19, so the build date is an important check before ordering.

This alternator uses an internal regulator, a 7 groove pulley with a 62.5mm outside diameter, and a 58mm mount leg thickness. It is supplied as an each unit and carries OEX part number DXA4174.

There are two identical looking alternators with different regulator functions, so the correct match needs to be confirmed by OE number. That is especially important when the alternator appears visually similar but the charging control setup is different.

Application and Buying Notes

The main compatibility checkpoint for this alternator is build date: it suits vehicles from 06/16 to 06/19. If the vehicle falls outside that range, the alternator should not be assumed to fit, even if it looks similar or the connector appears close.

This unit is a Denso style alternator with a single leg mount, internal regulator, 90A output, and a 7 groove pulley measuring 62.5mm outside diameter. Those details matter because alternator mounts, pulley layout, and regulator type all need to line up with the vehicle’s charging system.

There are two identical looking alternators listed with different regulator functions. That makes OE number matching the safest way to verify the correct part. The part number is DXA4174, and the vehicle’s original alternator details should be checked carefully before fitting.

The mounting measurements can help confirm whether the housing and brackets are correct: mount leg thickness is 58mm, mount centre to centre is 160mm, pivot hole diameter is 10, and the adjusting hole is M8x1.25. If any of those points differ from the removed unit, the part should be rechecked before installation.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. If the vehicle is used commercially, it is worth confirming that the application and duty cycle match the intended warranty category before the purchase is finalised.

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 DXA4174 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 DXA4174, 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.

Compatibility note: Confirm fitment using part number DXA4174, the 06/16 to 06/19 build window, and the OE number from the original alternator. Because two similar alternators are noted with different regulator functions, do not rely on appearance alone.
