OEX Alternator 12V 90A Denso Style DXA4112

The OEX Alternator DXA4112 is a new 12V, 90A alternator built in a Denso style with an internal regulator and a 6 groove pulley. It is listed as a twin leg mount unit with a 175mm mount centre-to-centre, 51mm inside mounting legs, and a pulley outside diameter of 55mm.

This alternator suits Denso unit applications and is supplied as each. Key dimensions include an M10x1.25 / 11 pivot hole, M8x1.25 adjusting hole, and a weight of 5.1kg. Those measurements matter when you are checking bracket alignment, pulley alignment, and whether the replacement will physically sit where the original unit did.

The listed fitment information includes Lotus Elise applications, with model references shown across multiple years. As with any alternator replacement, the part number DXA4112 and the mounting dimensions should be checked against the original unit before ordering, especially where the vehicle has been modified or the existing alternator has been replaced before.

Application and Buying Notes

Before buying, compare the alternator on the vehicle with the listed DXA4112 details: 12V, 90A, internal regulator, twin leg mount, 175mm mount centre-to-centre, and 6 groove pulley. Matching the physical mounting points is just as important as matching voltage or amperage, because a unit can be electrically suitable but still not line up correctly in the bracket.

The pulley details also need attention. This unit has a 55mm outside diameter pulley with a 6 groove section, so belt style and pulley configuration should be checked against the existing alternator. If the belt system on the vehicle does not match those details, the alternator may not be suitable even if the application appears similar.

This unit suits Denso applications and is identified as a Denso style alternator, so the safest approach is to verify the original alternator part number, mount type, and hole sizes before purchase. The listed pivot hole diameter is M10x1.25 / 11 and the adjusting hole diameter is M8x1.25, which are useful checkpoints when confirming interchange.

The warranty listed is 3 years for passenger use and 1 year for commercial use. Warranty terms do not replace fitment checks, so it is still important to confirm the alternator assembly, pulley section, and mounting geometry match the vehicle requirements before installation.

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 DXA4112 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 3yr Passenger 1yr Commercial, Inside Mounting Legs 51mm, Pivot Hole Diameter M10x1.25 / 11, Pulley Outside Diameter 55mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 175mm, Weight 5.1kg.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. DXA4112, Brand OEX, Description OEX Alternator 12V 90A Denso Style, Adjusting Hole Diameter M8x1.25, Pin Code IR116, Power Rating (Amp) 90, Pulley Section 6 Groove, Suits Unit Make Denso, Alternator Mount Twin Leg.

OEX Alternator 12V 90A Denso Style. Part number DXA4112 should be checked first. Listed voltage is 12. Listed output rating is 90. 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 DXA4112, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using the part number DXA4112, the Denso style application, and the listed mounting and pulley dimensions before ordering. Do not rely on model name alone, as alternator brackets, pulley grooves, and regulator types can vary between applications.
