OEX Alternator 12V 180A Denso Style DXA4068

The OEX Alternator DXA4068 is a new 12V unit rated at 180 amps, built in a Denso style with a pad mount and internal regulator. It uses an 8 groove pulley with a 58mm outside diameter, and the unit weight is listed at 7.18kg.

This alternator is identified with pin code IR115 and is supplied as part no. DXA4068. The mounting dimensions supplied are an 11mm adjusting hole diameter and an 11mm pivot hole diameter, so matching the physical layout is an important step before ordering.

OEX positions this alternator range as aftermarket support with quality and reliability in mind, and the product is backed by a 3 year passenger / 1 year commercial warranty. As with any charging system component, the correct match depends on the part number, mounting style, pulley configuration, voltage, and application details.

The listed fitment data references Toyota and Lexus applications, including Toyota Land Cruiser, Toyota Tundra, and Lexus LX. Because alternators can vary by engine, bracket arrangement, pulley setup, and connector type, it is worth checking every identifying detail against the vehicle before fitting.

Application and Buying Notes

Before ordering, confirm the alternator part number DXA4068 matches the unit being replaced, then compare the mounting style, pulley section, and connector details. This unit is a Denso style, 12V, 180A alternator with a pad mount and internal regulator, so those details need to line up with the vehicle’s existing charging system.

The pulley arrangement is one of the most important checks on an alternator like this. This unit uses an 8 groove pulley with a 58mm outside diameter, so the belt setup should be inspected closely. If the belt, pulley, or bracket arrangement differs from the original unit, the alternator may not be the correct match even if the vehicle model appears on a fitment list.

Physical measurements also matter. The supplied adjusting hole diameter and pivot hole diameter are both 11mm, and the unit weighs 7.18kg. Those details help confirm whether the alternator will sit correctly in the bracket and line up as expected during installation.

Fitment data supplied for this alternator references Toyota Land Cruiser, Toyota Tundra, and Lexus LX applications. That is useful as a guide, but alternators can vary across model years and build combinations, so it is still best practice to verify the old alternator, mounting pattern, pulley type, and pin code IR115 before purchase.

For commercial use, the warranty is listed as 1 year, while passenger use is listed as 3 years. If the vehicle is used in a mixed or commercial setting, it is sensible to confirm how the warranty applies before purchase and to keep the purchase details with the vehicle records.

The safest buying approach is to compare the part number, voltage, amperage, pulley section, mount type, and regulator type against the replacement unit already in the vehicle. If those details do not align, pause and confirm the application rather than relying on model name alone.

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 DXA4068 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.
