OEX Alternator 12V 130A Denso Style DXA4104

The OEX Alternator DXA4104 is a new 12V unit with a 130A power rating, built in a Denso style layout for applications that require this fitment profile. It uses an internal regulator, a pad mount arrangement, and a 7 groove pulley with a 58mm outside diameter, so matching the physical details matters as much as the electrical rating.

This alternator is listed under OEX part number DXA4104 and carries pin code IR116. It weighs 5.98kg and has a mount centre-to-centre measurement of 162mm, with a mount leg thickness of 60mm. Those dimensions are the practical checkpoints to confirm before ordering, particularly where the existing unit has to match closely to the vehicle’s mounting points and belt setup.

OEX describes this alternator range as an aftermarket option with a focus on quality and reliability, and the product is backed by a 3 year passenger / 1 year commercial warranty. For buyers comparing replacements, the combination of 12V operation, 130A output, Denso style construction, and the specified pulley and mounting details gives a clear basis for checking suitability against the original unit.

Application and Buying Notes

When replacing an alternator, the most useful checks are the part number, mounting style, pulley specification, and electrical output. This unit is identified as DXA4104, is a 12V alternator with a 130A rating, and uses a Denso style, pad mount design with an internal regulator. Those details need to line up with the vehicle’s existing setup before purchase, even where the vehicle model appears in the fitment data.

The pulley and mounting measurements are especially important here. The pulley is a 7 groove type with a 58mm outside diameter, while the mount centre-to-centre dimension is 162mm and the mount leg thickness is 60mm. If any of those dimensions differ from the original alternator, the part may not install correctly or may not align with the drive belt as intended.

The listed fitment preview includes Toyota RAV 4 applications from 2012 through 2018, but the fitment information is not complete enough to treat as a blanket guarantee. Use the vehicle’s existing alternator details, including the part number DXA4104 and pin code IR116, to compare carefully before placing an order.

For commercial use, the warranty is listed as 1 year, while passenger applications carry a 3 year warranty. That warranty detail is useful when comparing purchase options, but it does not replace the need to confirm the unit’s physical and electrical match to the vehicle. The safest approach is to verify the original alternator’s mounting points, pulley groove count, and connector style before fitting.

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 DXA4104 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.

FAQ

How do I confirm this part is the right match for my application?

Match DXA4104 against the original unit and compare the key specifications shown for the product, including voltage 12, output rating 130, mount style Pad, and pulley configuration 7 Groove. Fitment references can support the identification process, but they should not replace a direct part-number check.

What specifications should I compare before ordering?

The key checkpoints are the part number, voltage, amperage or output rating, mounting arrangement, pulley style, connector or terminal layout, and any listed OEM reference. Together, these details help confirm both physical fit and electrical suitability.

Does this listing include verified fitment information?

This item includes fitment information that can be used as an application guide. Final confirmation should still be based on the original component details and the exact application requirements.

Why is part number confirmation important even when the application looks similar?

Vehicles, trucks, tractors, and equipment can use different electrical units within the same model family. Part number confirmation reduces the risk of ordering a unit with the wrong output, mounting pattern, regulator setup, pulley arrangement, or connector style.

What does the listed electrical rating tell me about this unit?

The listing shows a voltage of 12. The listed output rating is 130. The regulator type is Internal. These details help identify whether the unit matches the original system requirements.

Is warranty information listed for this item?

Yes. The listed warranty is 3yr Passenger 1yr Commercial. Warranty should be considered alongside the part-number and application checks before purchase.
