OEX Alternator 12V 70A Denso Style DXA413

The OEX Alternator DXA413 is a 12V, 70 amp alternator in Denso style, supplied as a new unit with an internal regulator. It is listed with a 5 groove pulley, a 54mm pulley outside diameter, and a single leg alternator mount, so these physical details matter when matching it to the original unit in the vehicle.

Key mounting and connection dimensions for this alternator include a 58mm mount leg thickness, 165mm mount centre to centre, 10mm pivot hole diameter, M8x1.25 adjusting hole thread, and a 17mm shaft dimension. Those measurements are the practical checks that help confirm whether the alternator will physically sit and align correctly.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, and from ISO9001 certified factories. This alternator is backed by a 3 year passenger and 1 year commercial warranty, which is important to note when comparing it with a replacement for a Denso application.

The unit is identified as part number DXA413 and is suitable for Denso unit make applications. Because alternator fitment can vary on mount style, pulley configuration, and regulator type, it is best matched against the original part number and the listed dimensions before purchase.

Application and Buying Notes

When replacing an alternator, the safest match is the original part number and the physical configuration, not just the vehicle make. For this unit, the key identifiers are DXA413, Denso style, 12V, 70A, internal regulator, and a single leg mount with a 5 groove pulley.

The mounting measurements are particularly important. The listed 58mm mount leg thickness, 165mm mount centre to centre, 10mm pivot hole diameter, and M8x1.25 adjusting hole thread need to align with the existing bracket setup. If any of those dimensions differ, the alternator may not line up correctly even if the vehicle appears in the fitment list.

Pulley matching is another point to check carefully. This alternator has a 54mm pulley outside diameter and a 5 groove pulley section, so belt type and groove count should be confirmed against the vehicle’s existing drive arrangement before purchase.

If you are replacing a failed alternator, inspect the old unit for the part number, mount style, pulley section, and regulator type before deciding. The listed Denso application and the internal regulator are useful clues, but alternators with similar electrical ratings can still differ in bracket geometry or pulley specification.

This alternator is a new unit and weighs 4.64kg, which is consistent with a complete replacement rather than a repair component. If you are fitting to a vehicle from the listed application families, use the part number and dimensions as the final check, especially where multiple alternator variants may have been used across the same model range.

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 DXA413 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.
