OEX Alternator 12V 140A Denso Style DXA4007

The OEX Alternator DXA4007 is a 12V, 140A unit built in a Denso style with an external regulator. It is a new alternator with a twin leg mount, 6 groove pulley and a 57mm pulley outside diameter, so the physical mounting and drive details need to line up with the vehicle application before purchase.

This unit is listed with an inside mounting leg measurement of 68mm, a mounting centre-to-centre distance of 157mm, and a pivot hole diameter of M10x1.5 / 11. The adjusting hole diameter is 10mm. Those measurements are the key checks for confirming the alternator will sit correctly in the bracket and align with the belt system.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified. This alternator is backed by a 3 year passenger / 1 year commercial warranty, which gives a useful reference point for owners, workshop buyers, and repairers needing a replacement rotating electrical unit.

Application and Buying Notes

For this alternator, the most important checks are the part number DXA4007, the Denso style body, and the mounting dimensions. The unit is a twin leg design with 68mm inside mounting legs, 157mm centre-to-centre, an M10x1.5 / 11 pivot hole, and a 10mm adjusting hole. If any of those points differ from the original unit, it may not install correctly.

The electrical details also matter. This alternator is rated at 12V and 140A, and it uses an external regulator. That means the vehicle’s charging system specification needs to match the alternator type, not just the pulley or bracket pattern. The 6 groove pulley and 57mm outside diameter should also be checked against the existing drive arrangement.

This is a new alternator, not a remanufactured unit, and it weighs 5.66kg. That gives a useful reference when comparing it with the removed part. If you are replacing a failing alternator, compare the old unit carefully for regulator type, pulley section, mounting leg style, and all hole sizes before fitting the new one.

The available fitment preview points to Jeep Grand Cherokee applications, including model years from 1999 through 2009 in the supplied data. Even where a vehicle appears in the preview, confirm the exact match using the alternator part number and the mounting measurements. Small differences in bracket design, pulley section, or regulator setup can change compatibility.

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 DXA4007 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 DXA4007, 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 140 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 1999, JEEP GRAND CHEROKEE 2000, JEEP GRAND CHEROKEE 2001. 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 compatibility by matching part number DXA4007, Denso style application details, external regulator type, twin leg mount dimensions, and the 6 groove 57mm pulley against the original alternator and vehicle specifications before ordering.
