OEX Alternator 12V 80A Denso Style DXA422

The OEX Alternator DXA422 is a 12V, 80A unit built in a Denso style configuration and supplied new, not remanufactured. It suits Denso-type applications where the mounting layout, pulley section, regulator type and electrical output all match the vehicle’s original arrangement.

Key identifiers include part number DXA422, pin code IR11, internal regulator type and a 6 groove pulley. The alternator weighs 4.3kg and uses a single leg mount with a 165mm centre-to-centre mount dimension, a 58mm mount leg thickness, and a 10mm pivot hole diameter.

For buyers matching an existing alternator, the important checks are the 12V system voltage, 80 amp output, 64mm pulley outside diameter and M8 x 1.25 adjusting hole. Those details matter because Denso-style alternators can vary in mounting and pulley configuration even when the overall appearance is similar.

Application and Buying Notes

When comparing this alternator to the unit already fitted to the vehicle, check the 12V rating, 80A output, internal regulator, and the pulley details first. The 6 groove pulley, 64mm outside diameter and single leg mount need to align with the existing setup for a proper match.

The mounting measurements are also important. This unit has a 165mm mount centre-to-centre dimension, 58mm mount leg thickness, a 10mm pivot hole, and an M8 x 1.25 adjusting hole. Those dimensions are useful when confirming whether the alternator will physically sit and bolt up as expected.

The listed fitment references include several HOLDEN, LEXUS and TOYOTA applications, but matching by make alone is not enough. Alternators can differ by engine, bracket, pulley and charging configuration, so the safest approach is to confirm part number DXA422 against the vehicle’s original alternator details before purchase.

This is a new OEX alternator, and the warranty listed is 3 years for passenger use or 1 year for commercial use. Warranty coverage should be considered alongside the intended use of the vehicle, especially where the alternator will see higher duty cycles or frequent electrical load.

If the existing unit is unavailable for comparison, measure the mount points and count the pulley grooves before ordering. The key compatibility checkpoints here are Denso style, IR11 pin code, internal regulator, 12V system voltage and 80A output, as these are the most practical identifiers for narrowing the correct replacement.

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 DXA422 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 3yr Passenger 1yr Commercial, Mount Leg Thickness 58mm, Pivot Hole Diameter 10, Pulley Outside Diameter 64mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 165mm, Weight 4.3kg.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. DXA422, Brand OEX, Description OEX Alternator 12V 80A Denso Style, Adjusting Hole Diameter M8 x 1.25, Pin Code IR11, Power Rating (Amp) 80, Pulley Section 6 Groove, Suits Unit Make Denso, Alternator Mount Single Leg.

OEX Alternator 12V 80A Denso Style. Part number DXA422 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 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA422, 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 HOLDEN APOLLO, HOLDEN APOLLO 1993, HOLDEN APOLLO 1994, HOLDEN APOLLO 1995, LEXUS ES, LEXUS ES 1991. 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: Please confirm fitment using part number DXA422 and the alternator’s mounting, pulley and electrical specifications against the vehicle application before ordering. Do not rely on vehicle make alone.
