OEX Alternator 12V 80A Denso Style DXA4150

The OEX Alternator DXA4150 is a new 12V 80A unit built in a Denso style with an internal regulator. It suits applications that call for a twin leg alternator mount, 42mm inside mounting legs, and a 4 groove pulley arrangement, so checking the physical mount and pulley setup before ordering is essential.

This alternator is supplied as an each unit and carries a listed weight of 4.2kg. Key identifying details include part number DXA4150, pin code IR116, adjusting hole diameter M8x1.25, mount centre to centre 160mm, and pulley outside diameter 57.5mm. Those measurements are the practical checkpoints that matter when matching a replacement alternator.

OEX states its products are sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, with ISO9001 certified factory support for engineering, testing and quality control procedures. The listed warranty is 3 years for passenger use and 1 year for commercial use, which gives a clear reference point when selecting the correct replacement for a compatible Denso style application.

Application and Buying Notes

This alternator should be checked against the vehicle’s existing mount and pulley arrangement before purchase. The key physical identifiers are the twin leg mount, 42mm inside mounting legs, 160mm mount centre to centre, M8x1.25 adjusting hole, and 4 groove pulley with a 57.5mm outside diameter. If any of those dimensions differ from the fitted unit, the part should not be assumed correct.

The Denso style designation matters because alternators can look similar while still using different mounting points, pulley sections, or regulator types. Here the regulator is internal, the unit is 12V, and the output is 80A, so the replacement should be matched to the electrical requirement as well as the physical fit. Checking the pin code IR116 is also worthwhile when comparing connectors and applications.

The listed fitment references Toyota Ractis across 2005 through 2010 in the supplied application data. Even with that guidance, it is still best practice to compare the vehicle’s existing alternator details, part number DXA4150, and any visible mount or pulley markings before ordering. That is particularly important where the vehicle has been modified, repaired, or fitted with a non-original charging system.

As with any charging system component, condition of the battery, belt, wiring, and connectors should be checked during installation. A new alternator with an 80A rating can only operate correctly when the rest of the system is in sound condition, so a replacement should be fitted with care and verified once installed.

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 DXA4150 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 DXA4150 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 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4150, 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 RACTIS, TOYOTA RACTIS 2005, TOYOTA RACTIS 2006, TOYOTA RACTIS 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.

Compatibility note: Confirm fitment by comparing part number DXA4150, Denso style application details, twin leg mount measurements, pulley section, and the vehicle’s existing alternator before purchase. If the physical dimensions or connector details do not match, do not assume compatibility.
