OEX Alternator 12V 180A Denso Style DXA4143HO

The OEX Alternator DXA4143HO is a new 12V, 180A unit in Denso style, supplied as a pad mount alternator with an internal regulator. It is listed with a 9 groove pulley, 58mm pulley outside diameter, and a 10mm mount hole diameter, so the physical mounting details need to be checked against the vehicle before purchase.

This alternator is described as a high output upgrade from the original 150A unit to 180A, and it comes with cable and fuse included for the upgrade. The unit is also fitted with a semi-sealed brush box to help minimise entry of debris into the brush box area.

Application details provided for this part include Toyota LandCruiser VDJ79R and VDJ200R with the 4.5L 1VD-FTV engine. The unit is marked for use with Denso-style applications and carries OEX part number DXA4143HO, with OEM number DXA570HO also listed for reference.

Application and Buying Notes

Before ordering, compare the part number DXA4143HO and the listed OEM number DXA570HO with the alternator currently fitted to the vehicle. The important physical points on this unit are the pad mount style, 10mm mount hole diameter, 161mm mount centre to centre, 64mm inside mounting legs, and 60mm mount leg thickness.

This is a 12V, 180A alternator, so it is intended as a higher output replacement than the original 150A unit noted in the product features. That makes the electrical rating an important check, especially if the vehicle has charging demand from added accessories or a system that was originally matched to a lower output alternator.

The pulley arrangement also matters. This unit has a 9 groove pulley with a 58mm outside diameter, so belt type and alignment should be checked against the existing setup rather than assumed from model name alone. The alternator is listed as a new Denso-style unit with an internal regulator, so those details should also match what the vehicle requires.

The supplied cable and fuse are included for the upgrade, but installation should still be approached as a proper fitment check rather than a straight visual swap. If the original alternator differs in mount style, pulley section, connector arrangement, or physical dimensions, the vehicle may need additional checking before installation.

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 DXA4143HO 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 180A Denso Style. Part number DXA4143HO should be checked first. Listed voltage is 12. Listed output rating is 180. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is 9 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4143HO, 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 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include TOYOTA LAND CRUISER, TOYOTA LAND CRUISER 2007, TOYOTA LAND CRUISER 2008, TOYOTA LAND CRUISER 2009. 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: Confirm fitment using DXA4143HO, the OEM reference DXA570HO, and the vehicle’s mounting and charging system details before purchase. The listed Toyota LandCruiser applications are specific to VDJ79R and VDJ200R 4.5L 1VD-FTV details, so do not rely on model name alone when checking compatibility.
