OEX Alternator 12V 130A Denso Style DXA4071

The OEX Alternator DXA4071 is a 12V, 130A rotating electrical unit in Denso style, supplied new and sold each. It uses an internal regulator, a 7 groove pulley, and a twin leg alternator mount, so the physical layout needs to line up with the vehicle’s original setup before ordering.

Key dimensions include 72mm inside mounting legs, 171mm mount centre to centre, 10.5mm pivot hole diameter, 10.5mm adjusting hole diameter, and a 55mm pulley outside diameter. The unit weighs 6.4kg, which is a useful check when comparing against the original alternator.

This alternator is listed with part number DXA4071 and pin code IR203. The unit suits Denso applications, and the fitment information supplied includes Land Rover Range Rover Sport and several Nissan applications, but the exact match still needs to be confirmed against part number and vehicle details.

For buyers comparing replacement alternators, the most useful checks here are 12V system voltage, 130 amp output, twin leg mounting, 7 groove pulley arrangement, and the Denso style configuration. Those points matter as much as the vehicle badge when matching a charging system component.

Application and Buying Notes

Before buying, compare the alternator on the vehicle with the listed mounting and pulley details: twin leg mount, 72mm inside mounting legs, 171mm mount centre to centre, 10.5mm pivot hole, 10.5mm adjusting hole, and a 55mm 7 groove pulley. Those measurements are the practical checks that help confirm whether the unit will bolt up and drive correctly.

The charging output is 130A at 12V, so this is the right style of replacement only if the original system uses the same electrical specification. A mismatch in voltage, regulator type, or pulley configuration can affect installation and charging behaviour, even if the unit looks similar at first glance.

This alternator is new and suited to Denso applications, with OEX part number DXA4071 and pin code IR203. When a vehicle has multiple alternator variants across a model range, the part number and physical dimensions are the safest way to verify you are ordering the correct unit.

The supplied fitment preview includes Land Rover Range Rover Sport and Nissan Altima, Elgrand, Maxima, Murano, and Pathfinder applications, but model year, engine, and build variation still matter. Check the original unit, matching connector details, and mounting arrangement before finalising the order.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. That warranty does not replace fitment checking, so it is still important to confirm the physical and electrical specifications against the vehicle before installation.

At 6.4kg, this alternator is a substantial rotating electrical component, so careful comparison of the original unit is worthwhile. If the old alternator is available, matching the mounting ears, pulley groove count, and regulator style is often the quickest way to avoid ordering the wrong part.

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 DXA4071 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.

OEX Alternator 12V 130A Denso Style. Part number DXA4071 should be checked first. Listed voltage is 12. Listed output rating is 130. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4071, 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 130 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 2006, LAND ROVER RANGE ROVER SPORT 2007, LAND ROVER RANGE ROVER SPORT 2008, NISSAN ALTIMA, NISSAN ALTIMA 2013. 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.

Compatibility note: Confirm compatibility by checking OEX part number DXA4071, pin code IR203, 12V charging system requirements, 130A output, twin leg mounting, and the 7 groove pulley arrangement against the vehicle’s original alternator and application details.
