OEX Alternator 12V 110A Denso Style DXA4041

The OEX Alternator DXA4041 is a new 12V unit rated at 110A, built in a Denso style configuration for applications that suit a Denso unit. It uses an internal regulator, a single leg alternator mount, and an AA pulley section, with a pulley outside diameter of 76mm.

Key mounting details matter with alternators, and this unit is listed with a 165mm mount centre-to-centre measurement, 58mm mount leg thickness, a 10mm pivot hole diameter, and an M8 x 1.25 adjusting hole. Those measurements are the sort of details that need checking against the vehicle before ordering.

This is an OEX rotating electrical part, sold each, with part number DXA4041 and pin code IR11. The alternator weighs 6.4kg and is backed by a 3 year passenger / 1 year commercial warranty.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with ISO9001 certified factories supporting engineering, testing, and quality control procedures. That is useful context when you are matching a replacement alternator where fitment accuracy matters as much as output rating.

Application and Buying Notes

Before buying, compare the part number DXA4041, the Denso style design, and the listed mounting dimensions against the unit already fitted to the vehicle. The 165mm mount centre-to-centre measurement, 58mm mount leg thickness, 10mm pivot hole, and M8 x 1.25 adjuster hole are all practical checks that help separate a close match from the correct match.

The 110A output and 12V rating are important where the replacement alternator needs to match the vehicle’s electrical setup. The internal regulator and single leg mount also need to align with the existing alternator arrangement, because these features affect how the part installs and operates in the vehicle.

The pulley details should also be checked carefully. This unit has a 76mm outside diameter pulley with an AA section, so the belt profile and pulley size should be compared with the original unit rather than assumed. If the belt or pulley arrangement differs, it may not be the right replacement even when the alternator looks similar.

If you are working from a vehicle listing, use it as a guide only and confirm the specific application against the part number and physical measurements. The supplied fitment preview mentions Lexus IS and Toyota Land Cruiser applications, but the correct choice still depends on the exact vehicle variant and the specifications of the unit being replaced.

For best results, match the old alternator’s regulator type, mount style, pulley section, and hole sizes before ordering. That is especially important on Denso style units, where small differences in mounting or pulley configuration can affect installation even when the overall appearance is very similar.

This alternator is a new OEX unit and is covered by a 3 year passenger / 1 year commercial warranty. Warranty terms are useful, but they do not replace fitment checking, so it is still worth confirming the physical and electrical details carefully 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 DXA4041 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.
