OEX Alternator 12V 80A Denso Style DXA432

The OEX Alternator DXA432 is a new 12V, 80A unit built in a Denso style layout for applications that suit a Denso alternator and the listed mounting dimensions. It uses an internal regulator, a single leg mount, and an AA pulley section, so checking the original unit against the 72mm pulley outside diameter and 159mm centre-to-centre mount measurement is sensible before ordering.

This alternator is listed as part number DXA432 and suits unit make Denso. The mounting details include a 58mm mount leg thickness, 10mm pivot hole diameter, and M8x1.25 adjusting hole diameter, which are the kinds of measurements that matter when you are matching the replacement to the vehicle’s original setup.

As an 80 amp option, this unit is the correct choice only where that output matches the application. The note advises that the offered unit is 80 amp and suitability should be checked, with DXA4041 noted as a 110A alternative, so confirming output rating is just as important as confirming the physical fit.

Application and Buying Notes

The main checks for this alternator are the part number DXA432, the 12V electrical system, and the 80A output. If the vehicle originally used a Denso-style alternator, the 159mm mount centre to centre, 10mm pivot hole, M8x1.25 adjusting hole, and 72mm pulley diameter should be compared with the existing unit to avoid a mismatch.

Output rating matters as much as physical fit. This unit is an 80 amp alternator, and the note specifically indicates that suitability should be checked. Where the original alternator is a different amperage, the charging system specification needs to be matched carefully rather than assuming a direct swap.

The regulator is internal, so the replacement needs to suit an application designed for that arrangement. The single leg mount, 58mm mount leg thickness, and AA pulley section are all useful checkpoints when comparing to the old part, particularly if the existing alternator has been changed previously or the vehicle has seen non-standard repairs.

For a correct purchase, confirm the vehicle application, the Denso unit make, and the physical dimensions listed here before fitting. The alternator weighs 4.96kg and is supplied as a new unit, so it is intended as a direct replacement where the listed specifications align with the original equipment setup.

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 DXA432 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 80A Denso Style. Part number DXA432 should be checked first. Listed voltage is 12. Listed output rating is 80. These details form the core reference points used by parts interpreters when confirming the correct replacement.

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

For part number DXA432, 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 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include LEXUS IS, LEXUS IS 1999, LEXUS IS 2000, LEXUS IS 2001, TOYOTA LAND CRUISER, TOYOTA LAND CRUISER 1992. 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: Confirm compatibility by matching part number DXA432, the Denso style application, and the listed mounting and pulley dimensions to the vehicle’s original alternator before ordering.
