OEX Alternator 12V 80A Denso Style DXA4088

The OEX Alternator DXA4088 is a new 12V, 80A rotating electrical unit built in a Denso style with an internal regulator. It is supplied as an alternator with twin leg mounting, a 7 groove pulley, and a pulley outside diameter of 52.5mm, so the physical layout can be checked against the original unit before ordering.

This unit is listed with a 167mm mount centre-to-centre dimension, 44mm inside mounting legs, and an 11.5mm adjusting hole diameter. Those measurements matter when matching the alternator to the vehicle bracket and belt arrangement, particularly where the mounting points and pulley alignment need to line up with the existing setup.

OEX identifies this alternator as suitable for Denso applications, and the part number is DXA4088. It is a new part, weighs 4.58kg, and is covered by a 3 year warranty for passenger use or 1 year for commercial use, which gives a clear reference point for buyers comparing replacement options.

Application and Buying Notes

Before ordering, compare the part number DXA4088 with the number on the alternator you are replacing, then check the mounting style, pulley section, and overall dimensions. This unit has twin leg mounting, a 167mm mount centre-to-centre measurement, 44mm inside mounting legs, and an 11.5mm adjusting hole diameter, all of which need to match the vehicle installation.

The 12V, 80A output is important if you are replacing a unit with the same charging specification. An alternator with the wrong output rating, regulator type, or pulley style may physically bolt up but still be unsuitable for the vehicle’s electrical or belt setup, so it is worth confirming the original unit details before proceeding.

This OEX alternator uses an internal regulator and a 7 groove pulley with a 52.5mm outside diameter. Those are practical checks for belt alignment and connector arrangement, especially on Denso-style applications where similar-looking alternators can vary in mounting and pulley specification.

The unit is new and weighs 4.58kg, which can help when comparing against an existing alternator during inspection. If the vehicle is used in commercial service, note that the warranty term is 1 year; for passenger use, the warranty term is 3 years.

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 DXA4088 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 DXA4088 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 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 DXA4088, 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 TOYOTA HIACE, TOYOTA HIACE 2005, TOYOTA HIACE 2006, TOYOTA HIACE 2007. 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 fitment using the part number DXA4088, the Denso style application, and the measured mounting and pulley details before buying. Do not rely on appearance alone, as alternators with similar housings can differ in mount spacing, regulator type, or pulley section.
