OEX Alternator 12V 55A Denso Style DXA443

The OEX Alternator 12V 55A Denso Style is a new alternator with a 12V system and 55A power rating, supplied under part number DXA443. It is listed as a Denso-style unit with a twin leg alternator mount, internal regulator, and pulley section A, so the mounting and electrical details can be checked against the existing unit before purchase.

This alternator has an inside mounting legs dimension of 67mm, a mount centre to centre measurement of 156mm, an 8mm pivot hole diameter, and an M8x1.25 adjusting hole diameter. The pulley outside diameter is 69mm, and the unit weight is 3.34kg, which can help when comparing the replacement to the vehicle’s original alternator.

OEX products are sourced from original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified. This alternator is backed by a 3yr passenger / 1yr commercial warranty, so it is intended for customers who want a replacement part with clear identification, measured mounting points, and a defined application check before fitment.

Application and Buying Notes

Before ordering, compare the part number DXA443 and the measured mounting details against the alternator already on the vehicle. The key checks here are the 67mm inside mounting legs, 156mm mount centre to centre, 8mm pivot hole diameter, and M8x1.25 adjusting hole diameter, because these dimensions are what determine whether the unit will physically mount in the same position.

The alternator is a 12V, 55A Denso-style unit with an internal regulator and a 69mm pulley outside diameter. Those points matter because the charging system, pulley alignment, and connection style need to match the vehicle’s existing arrangement. If the original unit differs in mount style, pulley section, or regulator type, the part should be checked carefully before fitting.

Fitment is listed against a range of Holden and Suzuki applications, including Apollo, Barina, Drover, Alto, Apv, Baleno, Carry, Cultus, Grand Vitara, Hatch, Mighty Boy, Sierra, Swift, Vitara, and X-90. Even where a vehicle family is shown, the safest approach is still to confirm the original alternator shape, mounting points, and part number, because different variants can use different electrical or bracket arrangements.

The 3.34kg weight and twin leg mount give another useful comparison point when inspecting the existing unit. If the old alternator has a visibly different housing, pulley setup, or mounting ear spacing, the vehicle may require a different version. Matching by measurements and application details is the best way to avoid an incorrect purchase.

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 DXA443 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 55A Denso Style. Part number DXA443 should be checked first. Listed voltage is 12. Listed output rating is 55. 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 A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA443, 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 55 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HOLDEN APOLLO, HOLDEN APOLLO 1995, HOLDEN APOLLO 1996, HOLDEN APOLLO 1997, SUZUKI ALTO, SUZUKI ALTO 1985. 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 part number DXA443, the 12V 55A specification, twin leg mounting, and the listed measurements before ordering. The vehicle application list should be used as a guide only, and the existing alternator should be checked for matching mount centres, hole sizes, pulley section, and regulator type.
