OEX Alternator 12V 100A Denso Style DXA4083

The OEX Alternator 12V 100A Denso Style is a new rotating electrical unit supplied as a 12 volt, 100 amp alternator with internal regulation. It is identified by part number DXA4083 and is listed as a Denso style replacement, so the key match points are the mounting layout, pulley configuration and electrical specification rather than just the vehicle badge.

This unit is configured with a twin leg alternator mount, 51mm inside mounting legs, a 176mm centre-to-centre mount spacing, and a pivot hole diameter of M10x1.25 / 11. It also uses an M8 x 1.25 adjusting hole and a 55mm pulley with a 6 groove section, which are all details worth checking carefully against the original unit before ordering.

OEX positions this alternator range as a quality aftermarket option, with ISO9001 certified factories supporting engineering, testing and quality control procedures. It is backed by a 3 year passenger / 1 year commercial warranty, and the unit weight is listed at 5.8kg.

Application and Buying Notes

When replacing an alternator, the safest approach is to match the part number DXA4083, then confirm the physical details against the removed unit. This alternator is a 12V, 100A Denso style unit with a twin leg mount, 176mm mount centre-to-centre, 51mm inside mounting legs, and a 55mm 6 groove pulley, so those measurements should line up with the vehicle setup before you commit.

Pay close attention to the mounting hole sizes as well. The pivot hole is listed as M10x1.25 / 11 and the adjusting hole as M8 x 1.25, which means the brackets and fasteners need to match the alternator and the vehicle application. If the original alternator differs in pulley count, bracket style or regulator arrangement, it is better to verify that first rather than assume interchangeability.

This unit is listed for Toyota Corolla and Toyota RAV 4 applications in the supplied fitment data, including Corolla 2006 through 2012 and RAV 4 2012 through 2014. Even with that reference, alternator fitment can still vary with engine, build date, bracket design and electrical specification, so the original part number and the physical mounting layout remain the most reliable checks.

The 100 amp output and internal regulator make this a direct electrical-spec match only when the charging system is designed for that setup. If your vehicle currently uses a different amperage rating, a different pulley style, or a different connector arrangement, confirm those details before fitting. The unit is new and weighs 5.8kg, which is also useful when comparing the replacement to the removed alternator.

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 DXA4083 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.

For part number DXA4083, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include TOYOTA COROLLA, TOYOTA COROLLA 2006, TOYOTA COROLLA 2007, TOYOTA COROLLA 2008. 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: Please confirm fitment with part number DXA4083 and verify the mounting, pulley and electrical details against the original alternator before ordering. Vehicle application details are a guide only and should be checked against the actual unit in the vehicle.
