OEX Alternator 12V 180A Denso Style DXA4132

The OEX Alternator DXA4132 is a new 12V, 180A unit in Denso style, supplied with a pad mount and internal regulator. It is intended for applications that match the listed mounting details, including a 50mm mount leg thickness, 49mm mount centre-to-centre measurement, and 10mm adjusting hole diameter.

This alternator uses a 6 groove pulley with a 54mm outside diameter and is listed with Pin Code IR169. The unit weighs 7.1kg, so it is worth confirming the physical layout on the vehicle before ordering, especially where the alternator sits close to brackets, belt hardware, or shrouding.

OEX positions this range as an aftermarket option backed by ISO9001 certified factory processes and a warranty of 3 years for passenger use or 1 year for commercial use. As with any charging system part, the key checks are the part number DXA4132, the Denso style form, and the exact mounting and pulley details on the existing unit.

Application and Buying Notes

Charging system parts need to match the vehicle and the old unit closely, not just the make and model name. For this alternator, the important identifiers are DXA4132, Denso style, 12V, 180A, pad mount, internal regulator, and the 6 groove pulley with a 54mm outside diameter.

The mount measurements are equally important. Check the 50mm mount leg thickness, 49mm mount centre-to-centre measurement, and 10mm adjusting hole diameter against the current alternator. If those dimensions do not line up, the unit may not sit correctly even if the vehicle appears to be listed.

Land Rover Range Rover Sport fitment is shown in the supplied application data, including model years from 2013 through 2020 in the preview. That still does not replace a direct check of the alternator already fitted to the vehicle, as variations can exist within the same model range.

If you are replacing a failed alternator, compare the pulley section, regulator type, and mounting style before removing the old unit. The 7.1kg weight, pad mount design, and IR169 pin code are useful reference points when confirming the correct replacement and avoiding unnecessary returns.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. As always, warranty coverage does not remove the need to verify compatibility first, particularly on vehicles where charging system parts may vary by build date or equipment level.

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 DXA4132 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 DXA4132, 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.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include LAND ROVER RANGE ROVER SPORT, LAND ROVER RANGE ROVER SPORT 2013, LAND ROVER RANGE ROVER SPORT 2014, LAND ROVER RANGE ROVER SPORT 2015. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment by checking the part number DXA4132, Denso style, 12V 180A rating, pad mount layout, internal regulator, pulley details, and the vehicle application details before purchase.
