OEX Alternator 12V 70A Denso Style DXA4103

The OEX Alternator DXA4103 is a new 12V, 70 amp alternator in Denso style, supplied as an each unit for rotating electrical applications. It uses an internal regulator, a 5 groove pulley, and a single leg alternator mount, so the physical layout and electrical specification can be checked before purchase against the vehicle’s existing unit.

Key dimensions recorded for this alternator include a 55mm pulley outside diameter, 58mm mount leg thickness, and a 10.2mm pivot hole diameter. The unit weighs 4.2kg and carries pin code IR115, which are useful reference points when comparing against an original alternator or a matched replacement.

OEX positions this alternator range around quality and reliability at aftermarket pricing, with ISO9001 certified factories and a warranty that is listed as 3 years for passenger use and 1 year for commercial use. For buyers, the important detail is still the physical and electrical match: 12 volts, 70 amps, Denso unit make, and part number DXA4103.

Application and Buying Notes

Before buying, compare the part number DXA4103 with the unit currently fitted to the vehicle, then check the 12V system, 70A output, and Denso style specification. The alternator uses an internal regulator, so a vehicle that relies on an external regulator or a different control setup will not be a direct match.

The physical details matter just as much as the electrical rating. This alternator has a single leg mount, a 5 groove pulley, a 55mm pulley outside diameter, a 58mm mount leg thickness, and a 10.2mm pivot hole diameter. Those measurements help confirm whether the casing and mounting points line up with the existing component.

If you are matching by vehicle application, the supplied fitment points to Suzuki Alto coverage, including 2009 through 2014 in the grouped preview. That is useful guidance, but it should not replace a direct check of the existing alternator, belt arrangement, mounting bracket, and connector style before the part is fitted.

The 4.2kg weight, pin code IR115, and Denso unit make are also practical identifiers for workshop comparison. These details are especially useful when the vehicle has had prior repairs, a different alternator installed, or a non-standard pulley arrangement. Careful matching at the bench is the safest approach for any charging system replacement.

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 DXA4103 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 Part No. DXA4103, Brand OEX, Description OEX Alternator 12V 70A Denso Style, Mount Leg Thickness 58mm, Pivot Hole Diameter 10.2, Pulley Outside Diameter 55mm, Regulator Type Internal, Voltage 12, New / Reman. New.

OEX Alternator 12V 70A Denso Style. Part number DXA4103 should be checked first. Listed voltage is 12. Listed output rating is 70. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4103, 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 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by comparing part number DXA4103, the Denso style specification, 12V 70A rating, single leg mount, 5 groove pulley, and the listed measurements against the vehicle’s original alternator and application details before purchase.
