OEX Alternator 12V 150A Denso Style DXA4082

The OEX Alternator DXA4082 is a 12V, 150A unit built for Denso-style applications, with a 6 groove pulley and external regulator arrangement. It is supplied new, not remanufactured, and carries a listed weight of 5.8kg, which is useful when matching a replacement against the original unit.

This alternator is identified with part number DXA4082 and OEM number 68078950AA, so those references are the safest starting point when checking compatibility. The mounting layout is listed as single leg, with a mount leg thickness of 87mm, a pivot hole diameter of 11.5mm, and an adjusting hole diameter of 11.5mm.

For buyers comparing replacement charging units, the key details here are the 12V operating voltage, 150 amp output rating, and Denso unit make. These are the practical identifiers that help separate this alternator from similar-looking units that may differ in pulley type, regulator style, or mounting dimensions.

Application and Buying Notes

When replacing an alternator, the most important checks are voltage, output, regulator type, pulley section, and mounting geometry. This unit is rated at 12V and 150A, uses an external regulator, and has a 6 groove pulley with a 52mm outside diameter, so those details need to line up with the vehicle’s existing charging system and belt arrangement.

The physical dimensions matter just as much as the electrical rating. The mount leg thickness is 87mm, the pivot hole diameter is 11.5mm, and the adjusting hole diameter is 11.5mm. A unit can look close at first glance but still be wrong if the mounting points, spacing, or pulley setup do not match the original.

If you are comparing to the old alternator, check the part number DXA4082 and OEM number 68078950AA first, then compare the Denso-style application, single leg mount, and weight of 5.8kg. These identifiers give a more reliable match than appearance alone, especially where similar alternators exist with different regulators or pulley grooves.

The warranty listed is 3 years for passenger use and 1 year for commercial use. That provides a clear usage distinction, but it does not replace fitment checking. Commercial vehicles, modified charging systems, and vehicles with non-standard repairs should be verified carefully before ordering.

If you are unsure, compare the old unit side by side with the listed specifications before fitting. Alternators are one of the easiest parts to misidentify by shape alone, so the safest approach is to match the electrical rating, pulley type, regulator style, mount configuration, and part numbers together.

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 DXA4082 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 150A Denso Style. Part number DXA4082 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. 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 DXA4082, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include JEEP GRAND CHEROKEE, JEEP GRAND CHEROKEE 2010, JEEP GRAND CHEROKEE 2011, JEEP GRAND CHEROKEE 2012. 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 using part number DXA4082, OEM number 68078950AA, and the listed application details before ordering. Match the 12V 150A specification, external regulator, 6 groove pulley, and single leg mounting dimensions against the existing alternator on the vehicle.
