OEX Alternator 12V 210A Denso Style DXA4134

The OEX Alternator DXA4134 is a new 12V unit rated at 210 amps and built in a Denso style configuration. It is supplied as a twin leg alternator with an internal regulator, a 6 groove pulley, and a 49mm pulley outside diameter, so the key mounting and drive details can be checked before ordering.

This alternator is listed with a part number of DXA4134 and a pin code of IR228. The mounting measurements supplied include 75mm inside mounting legs, a 127mm centre-to-centre mount dimension, a M10x1.5 / 10 pivot hole diameter, and a 10mm adjusting hole diameter. Those dimensions are the practical checks that matter when comparing the unit to the vehicle or the removed alternator.

OEX positions this alternator range as quality aftermarket rotating electrical equipment, with factories that are ISO9001 certified. The warranty listed for this unit is 3 years for passenger use and 1 year for commercial use, which is useful context for buyers who want a new replacement with defined support terms.

Application and Buying Notes

Before ordering, compare the part number DXA4134 with the alternator being replaced and check the mounting layout against the supplied dimensions: 75mm inside mounting legs, 127mm centre-to-centre, and a twin leg mount. These dimensions are often the quickest way to confirm whether the housing and brackets line up correctly.

The pulley and electrical details also need attention. This unit uses a 6 groove pulley with a 49mm outside diameter and an internal regulator, so the belt type and charging system setup need to match the vehicle specification. A 12V, 210A alternator is not a universal fit just because the physical shape looks similar.

The listed application notes show Denso as the unit make, with fitment tokens referencing BMW and BMW X5 sample applications. That is a useful starting point, but it is still important to confirm the exact application against the part number, mount measurements, pulley configuration, and regulator type before purchase.

Weight is listed at 7.3kg, which can help when comparing against the removed unit during an in-store or workshop check. If the old alternator carries a different pulley section, different fixing pattern, or different regulator arrangement, the correct match should be selected by specification rather than appearance alone.

The warranty is 3 years for passenger use and 1 year for commercial use. If the alternator is going into a vehicle that sees heavier duty service, it is worth considering the operating conditions carefully and making sure the installation details are correct so the unit is fitted to the intended application.

OEX notes that its factories are ISO9001 certified and that the brand has experience supplying aftermarket rotating electrical products. Even with that background, the safest approach is still to confirm the vehicle application, check the removed unit against the listed measurements, and verify the part number before finalising the order.

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 DXA4134 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 210A Denso Style. Part number DXA4134 should be checked first. Listed voltage is 12. Listed output rating is 210. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. 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 DXA4134, 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 210 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm compatibility using part number DXA4134, the Denso style application, and the listed mounting and pulley measurements before buying. Fitment should be checked against the vehicle and the existing alternator, as matching the numbers and dimensions is the best way to avoid ordering the wrong unit.
