OEX Alternator 12V 180A Denso Style DXA4063

The OEX Alternator DXA4063 is a new 12V, 180 amp alternator in Denso style with a pad mount and external regulator. It is listed with a 6 groove pulley, 52mm pulley outside diameter, 176mm mount centres C, and a 7.28kg weight, so the physical layout and electrical style both need to match the vehicle application before fitting.

This unit uses pin code ER55, with the note that F1 is field positive feed from the computer and S is 2.4K ohms sense to computer. Those control details matter as much as the mounting dimensions, especially where the vehicle charging system relies on a specific regulator and field wiring arrangement.

OEX positions this alternator range as an aftermarket option backed by ISO9001-certified manufacturing processes, and this unit carries a 3 year passenger / 1 year commercial warranty. As with any alternator replacement, correct identification by part number, mount type, pulley configuration, and regulator type is essential before ordering.

Verified fitment guidance

• Fitment is not fully verified here by vehicle model, so confirm against the part number DXA4063 and the matching mounting and regulator details before purchase.
• Known application references include Chrysler 300C, Jeep Grand Cherokee, and Jeep Wrangler in the supplied fitment data.
• Sample application years shown include Chrysler 300C 2005, 2006, 2007, 2008 and 2011, plus Jeep Grand Cherokee 2010 through 2018, and Jeep Wrangler 2011.
• Because alternators can differ by pulley, mount, and field/sense wiring, match the 12V, 180A, 6 groove, external regulator configuration as well as the physical dimensions.

Application and Buying Notes

Before ordering, compare the replacement unit to the existing alternator by part number DXA4063, mount type, and pulley setup. The listed 176mm mount centres C, 50mm inside mounting legs, 60mm mount leg thickness, and 9.8mm pivot hole diameter are all practical checkpoints that help confirm whether the alternator will physically sit correctly in the vehicle.

Electrical compatibility is just as important as the bracket fit. This alternator is 12V, rated at 180A, uses an external regulator, and carries pin code ER55 with F1 field positive feed from the computer and S sense to computer at 2.4K ohms. If the vehicle uses a different regulator arrangement or wiring logic, the alternator may not be suitable even if the mounting points look close.

The 6 groove pulley and 52mm pulley outside diameter should also be checked against the belt system already fitted to the vehicle. Belt alignment and groove count need to match, otherwise the alternator may not run correctly or may cause belt wear. When possible, compare the old unit directly before removing it from the vehicle.

This is a new OEX alternator, and the warranty is listed as 3 years for passenger use and 1 year for commercial use. That does not replace proper identification, so confirm the application carefully if the vehicle is used commercially, modified, or has had charging system parts changed previously.

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 DXA4063 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 180A Denso Style. Part number DXA4063 should be checked first. Listed voltage is 12. Listed output rating is 180. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is External. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4063, 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 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number DXA4063, 12V 180A output, Denso style, external regulator type, ER55 pin code, and the listed mounting and pulley measurements against the vehicle before ordering.
