OEX Alternator 12V 160A Denso Style DXA552HO

The OEX Alternator 12V 160A Denso Style, part number DXA552HO, is a new alternator with a 12V system voltage and a 160A power rating. It is listed with a Denso unit make, internal regulator, single leg alternator mount, and 7 groove pulley, so it suits buyers looking for a defined replacement rather than a generic match.

This unit is noted as an upgrade from the original 130A setup to a 160A high output alternator, and the cable and fuse are included for the upgrade. That makes the current output increase a key point to check before purchase, especially where the vehicle’s charging system needs to support additional electrical load.

The product facts also identify TOYOTA Prado/Hilux 3.0L 1KD-FTV among the stated applications, with fitment data showing Toyota Hiace, Toyota Hilux, and Toyota Regius Ace references. Even with those application names available, the safest way to confirm suitability is still to match the part number, mounting style, pulley details, and electrical configuration against the existing unit.

Application and Buying Notes

When checking this alternator, the first items to confirm are the part number DXA552HO, the Denso style unit make, and the single leg mounting arrangement. The listed mount leg thickness is 58mm, the adjusting hole diameter is M8x1.25, and the pulley is a 7 groove design with a 58mm outside diameter, so those details should be compared carefully with the original unit already on the vehicle.

This alternator is rated at 160A and 12V, and it is described as an upgrade from an original 130A setup. That makes the charging requirement and the existing electrical system important considerations. If the vehicle previously ran a lower output alternator, the included cable and fuse are relevant parts of the upgrade and should be installed as supplied where the application calls for them.

The stated vehicle context includes Toyota Prado/Hilux 3.0L 1KD-FTV, along with Toyota Hiace, Toyota Hilux, and Toyota Regius Ace references in the fitment data. Even so, alternate charging system setups can exist within the same model line, so matching the regulator type, rotation direction, pulley configuration, and mounting points remains the most reliable way to avoid a mismatch.

As a new alternator, this unit is supplied with a 3yr Passenger / 1yr Commercial warranty. Warranty terms do not replace fitment confirmation, so it is still best practice to check the vehicle application, the current alternator type, and the physical measurements before installation planning. If the existing part differs in mount layout or pulley setup, the application should be reassessed before proceeding.

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 DXA552HO 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, Power Rating (Amp) 160, Pulley Section 7 Groove, Rotation CW, Voltage 12, New / Reman. New.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. DXA552HO, Brand OEX, Description OEX Alternator 12V 160A Denso Style, Adjusting Hole Diameter M8x1.25, Pin Code IR115, Pulley Outside Diameter 58mm, Regulator Type Internal, Suits Unit Make Denso, Alternator Mount Single Leg.

OEX Alternator 12V 160A Denso Style. Part number DXA552HO should be checked first. Listed voltage is 12. Listed output rating is 160. 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 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA552HO, 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 160 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number DXA552HO, 12V/160A output, Denso style construction, single leg mount, 7 groove pulley, and the listed application details against the vehicle before ordering.
