OEX Alternator 12V 70A Denso Style DXA4018

The OEX Alternator DXA4018 is a new 12V alternator rated at 70A and built in a Denso style configuration. It uses a single leg alternator mount with a 58mm mount leg thickness, a 5 groove pulley, and an internal regulator. Those details matter when you are comparing replacement charging components and checking that the bracket, pulley, and electrical setup match the vehicle requirements.

This unit is supplied as each and carries a 3 year passenger / 1 year commercial warranty. OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified. For a charging system component, that gives buyers useful context around manufacturing control and quality management without overstating what the part will do in a specific vehicle.

The key identifiers for this alternator are OEX part number DXA4018, 12V operating voltage, and 70 amp output. It also includes a 53mm pulley outside diameter, M8 adjusting hole diameter, 163mm mount centre-to-centre measurement, IR75 pin code, and a weight of 4.5kg. Those are the practical checkpoints to compare before ordering, especially if the original unit is being replaced rather than upgraded.

Application and Buying Notes

Before ordering, compare the part number DXA4018 and the physical details against the existing unit in the vehicle. The important points here are the 12V system, 70A output, Denso style configuration, single leg mount, 58mm mount leg thickness, and 5 groove pulley. If the replacement alternator differs in any of those areas, it may not be a direct swap.

The pulley and mounting measurements are especially worth checking on the bench before removal. This unit has a 53mm pulley outside diameter, M8 adjusting hole diameter, and 163mm mount centre-to-centre spacing. Those measurements help confirm whether the alternator brackets and belt alignment are likely to line up with the vehicle setup already fitted.

The internal regulator and IR75 pin code are also important compatibility checks. Electrical connectors and regulation style need to match the vehicle’s charging system arrangement, so it is best to compare the plug shape, pin count, and regulator type with the original alternator rather than relying on appearance alone. Even where a vehicle model appears in the fitment list, build variations can still exist.

The unit weighs 4.5kg and is listed as new, not remanufactured. If you are replacing a failed alternator, it is sensible to inspect the belt condition, pulley alignment, battery condition, and charge system wiring at the same time. A replacement alternator can only perform correctly when the surrounding components are in sound condition.

The warranty is 3 years for passenger use and 1 year for commercial use. That warranty detail is useful when planning the job, but it does not replace the need to confirm the application. Use the vehicle’s current alternator details, the part number DXA4018, and the listed mount and pulley measurements to check suitability before purchase.

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 DXA4018 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.

Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

Compatibility note: Please confirm fitment using OEX part number DXA4018, the Denso style application, and the measured mount, pulley, and connector details on the vehicle before ordering. Vehicle listings supplied include Suzuki Ignis and Suzuki Swift applications, but final compatibility should always be checked against the original alternator.
