OEX Alternator 12V 180A Denso Style DXA4126

The OEX Alternator DXA4126 is a 12V, 180A unit built in a Denso style configuration and supplied as a new alternator. It uses an internal regulator, a 6 groove pulley section, and a pad mount arrangement, which are all important checks when matching an alternator for replacement work.

Key physical details on this unit include a 52mm pulley outside diameter, 93mm mount leg thickness, 51mm mount centre to centre, and 10 / 11mm mount hole diameter. The listed weight is 7.12kg, so it is worth comparing the old unit closely before ordering, especially where access, bracket style, or pulley alignment is tight.

OEX positions this alternator range as an aftermarket option with quality and reliability in mind, and the product is backed by a 3 year passenger / 1 year commercial warranty. The brand also notes ISO9001 certified factories and manufacturing partnerships with major OEM suppliers, which gives useful context for buyers looking for a replacement rotating electrical unit rather than a guess-fit part.

Application and Buying Notes

Before buying, compare the part number DXA4126, the Denso style body, and the pad mount arrangement against your original alternator. These are the most reliable matching points here because the listed physical details include a 93mm mount leg thickness, 51mm mount centre to centre, and 10 / 11mm mount hole diameter.

The 6 groove pulley section and 52mm pulley outside diameter also need to line up with the belt system already on the vehicle. If the belt profile, pulley width, or pulley diameter differs from the removed unit, the alternator may not be suitable even if the electrical rating looks close.

This alternator is rated at 180A and 12V, with an internal regulator, so it is intended for applications that call for those exact characteristics. Always confirm the vehicle’s original alternator specifications, connector style, and mounting pattern before fitting, particularly when replacing a unit that may have been changed previously.

The supplied fitment data is limited and should be treated carefully. A sample application reference is shown for Jeep Cherokee, including a 2013 example, but that is not enough on its own to confirm fitment for every model or variant. Matching the part number and the measured mounting details is the safer approach.

If the existing alternator has heat damage, bearing noise, charging faults, or pulley wear, it is still important to compare the full specification set rather than relying on appearance alone. Alternators that look similar can differ in regulator type, mount spacing, or pulley section, and those differences matter for installation and charging performance.

As with any rotating electrical component, check the belt condition, mounting surfaces, and charge wiring at the same time. A new 12V 180A alternator such as this one will only perform as intended if the vehicle’s belt drive, terminals, and mounting hardware are in good condition and correctly matched to the unit.

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 DXA4126 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. DXA4126, Brand OEX, Description OEX Alternator 12V 180A Denso Style, Mount Hole Diameter 10 / 11, Power Rating (Amp) 180, Pulley Section 6 Groove, Suits Unit Make Denso, Alternator Mount Pad, Mount Cnt to Cnt 51mm.

OEX Alternator 12V 180A Denso Style. Part number DXA4126 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 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 DXA4126, 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 DXA4126, the Denso style design, pad mount arrangement, 12V 180A rating, internal regulator, and the listed mounting and pulley measurements against the vehicle’s original alternator before purchase.
