OEX Alternator 12V 90A Denso Style DXA4161

The OEX Alternator DXA4161 is a new 12V, 90A unit in Denso style with a twin leg alternator mount and internal regulator. It suits Denso applications and uses a 6 groove pulley with a 55mm outside diameter, so the mounting layout and pulley profile should be checked carefully before ordering.

This alternator has an inside mounting legs measurement of 51mm, a mount centre-to-centre measurement of 174mm, an M8x1.25 adjusting hole, and a pivot hole of M10x1.25 / 11. Those dimensions are the practical checks that matter when matching the replacement to the vehicle and the original unit.

OEX supplies this alternator as a new component, not remanufactured, and it carries a 3 year passenger / 1 year commercial warranty. The unit weight is listed at 5kg, which can also help when comparing against the removed alternator during inspection.

Application and Buying Notes

Before ordering, compare the alternator on the vehicle with the key matching points on this unit: part number DXA4161, 12V voltage, 90A output, Denso style, twin leg mount, and internal regulator. If any of those details differ from the original alternator, the part may not be correct even if the unit looks similar.

The physical dimensions are just as important as the electrical rating. Check the 51mm inside mounting legs, 174mm mount centre-to-centre, M8x1.25 adjusting hole, M10x1.25 / 11 pivot hole, and 6 groove pulley with 55mm outside diameter. These measurements are often the deciding factors when fitting a replacement alternator.

This is a new alternator, which may be preferred where the existing unit has bearing wear, charging issues, or damage to the housing or pulley. Even so, the correct choice still depends on matching the mounting arrangement and pulley configuration, because a 90A rating alone does not confirm interchangeability.

The listed fitment references Toyota RAV 4 applications across 2012 to 2018, but alternator fitment can vary with engine, build date, pulley arrangement, and charging system specification. It is worth checking the vehicle details against the removed unit and confirming the shape of the mount before purchase, particularly where the original alternator has a different leg spacing or regulator type.

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 DXA4161 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 DXA4161, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using part number DXA4161, the Denso style application, and the stated mounting and pulley measurements before ordering. Vehicle model references should be checked against the removed alternator and the actual charging system on the vehicle.
