OEX Alternator 12V 105A Denso Style DXA4181

The OEX Alternator DXA4181 is a new 12V, 105A unit in Denso style, supplied as an alternator for rotating electrical applications. It uses a pad mount arrangement, 6 groove pulley section, and a 51mm inside mounting leg measurement, so those details should be checked carefully against the vehicle or the removed unit before purchase.

This alternator is listed with a 12mm adjusting hole diameter, 48mm pulley outside diameter, and IR89 pin code. Those are the kind of fitment points that matter when matching an alternator correctly, especially where the mount style and pulley setup need to line up with the original component.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories operating under ISO9001 certified processes. The unit carries a 3 year passenger / 1 year commercial warranty, which gives a clear usage-based warranty structure for buyers needing a replacement rotating electrical part.

Application and Buying Notes

Before ordering, compare the OEX DXA4181 against the unit already fitted to the vehicle. The key matching points provided here are 12V, 105A, Denso style, pad mount, 6 groove pulley section, 51mm inside mounting legs, 12mm adjusting hole diameter, and IR89 pin code. If any of those differ from the original alternator, the part should be checked again before installation.

The pulley details are especially important because this unit has a 48mm pulley outside diameter and a 6 groove section. Alternators can look similar at a glance but still differ in mount geometry, pulley type, and connector style, so matching those details is the safest way to avoid a return or an incorrect fit.

This alternator is supplied new and weighs 4.92kg, so handling and comparison with the existing part can be done before the vehicle is stripped further. The warranty is listed as 3 years for passenger use and 1 year for commercial use, which is useful to note when the vehicle’s duty cycle is heavier or more frequent.

Where fitment data is only partial, the part number remains the most reliable reference. If the existing alternator has a different brand marking or a different housing layout, do not rely on appearance alone. Use the vehicle application details, the mount type, and the pin code together with DXA4181 to confirm the match.

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 DXA4181 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.
