OEX Alternator 12V 220A Denso Style DXA4072

This OEX alternator is a 12V, 220A unit with a Denso style construction and part number DXA4072. It is a new alternator, not remanufactured, and it uses an internal regulator with a pad mount arrangement.

Key physical identifiers include a 6 groove pulley, 52mm pulley outside diameter, 163mm mount centre to centre, 70mm mount leg thickness, and clockwise rotation. The pin code is IR211, and the unit weight is 7.22kg.

The alternator is listed as suitable for Denso applications, and the fitment preview includes Chrysler 300C and Jeep Grand Cherokee applications across multiple model years. Always compare the part number, mounting points, pulley layout, and regulator type before ordering.

OEX states the product line is supported by ISO9001 certified manufacturing processes and is backed by a 3yr passenger / 1yr commercial warranty. For buyers replacing a charging system component, matching the electrical rating and mounting details is just as important as the vehicle model name.

Application and Buying Notes

For a charging system replacement, the most important checks on this unit are the 12V system voltage, 220A output rating, internal regulator, and Denso style mounting. The alternator also uses a 6 groove pulley with a 52mm outside diameter, so belt and pulley matching should be confirmed against the vehicle already fitted.

The mounting pattern matters as much as the electrical rating. This unit is a pad mount alternator with 163mm mount centre to centre and 70mm mount leg thickness, so even a close-looking alternator may not physically line up if the bracket arrangement differs.

The pin code is IR211, which is another useful identifier when comparing connectors and regulator style. If the original alternator differs in plug shape, wiring, rotation, or pulley configuration, those differences need to be verified before fitting.

Because the fitment preview includes Chrysler 300C and Jeep Grand Cherokee applications, model name alone should not be used as the only check. Confirm the part number DXA4072, the mounting measurements, and the vehicle’s charging system details to avoid ordering the wrong unit.

This is a new OEX alternator and is supported by a 3yr passenger / 1yr commercial warranty. Warranty coverage does not replace the need to confirm the correct application, especially where the same model range may use different alternator specifications across years or engine variants.

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 DXA4072 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.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. DXA4072, Brand OEX, Description OEX Alternator 12V 220A Denso Style, Mount Leg Thickness 70mm, Power Rating (Amp) 220, Pulley Section 6 Groove, Rotation CW, Voltage 12, Mount Cnt to Cnt 163mm.

OEX Alternator 12V 220A Denso Style. Part number DXA4072 should be checked first. Listed voltage is 12. Listed output rating is 220. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. 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 DXA4072, 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 220 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CHRYSLER 300C, CHRYSLER 300C 2005, CHRYSLER 300C 2006, CHRYSLER 300C 2007, JEEP GRAND CHEROKEE, JEEP GRAND CHEROKEE 2005. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by matching part number DXA4072, the 12V 220A specification, Denso style construction, IR211 pin code, pad mount layout, and the vehicle’s existing alternator measurements and connector details before purchase.
