OEX Alternator 12V 130A Denso Style DXA4177

The OEX Alternator DXA4177 is a 12V, 130A unit in Denso style, supplied as a new alternator for rotating electrical applications. It is listed as a single leg alternator with a 6 groove pulley, a pulley outside diameter of 54mm, and a mount leg thickness of 60mm.

This alternator is identified with mounting details that matter when comparing replacements: 180mm centre-to-centre mount spacing and a 12mm adjusting hole diameter. Those dimensions are the practical checks that help confirm whether the unit lines up correctly in the vehicle before ordering.

OEX states the brand is sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, with products sourced from ISO certified factories. The unit carries a comprehensive nationwide warranty, with the stated warranty coverage of 3 years for passenger use and 1 year for commercial use.

Application and Buying Notes

For a replacement alternator, the important checks are the 12V system, 130A output, and the mounting design. This unit uses a single leg mount, 180mm mount centre-to-centre, a 12mm adjusting hole, and a 54mm pulley outside diameter, so those dimensions should be compared with the original alternator already fitted to the vehicle.

The 6 groove pulley section is another key point to confirm. If the belt profile does not match, the alternator may not align or drive correctly, even if the electrical rating is suitable. The stated mount leg thickness of 60mm is also worth checking when assessing bracket and spacing compatibility.

The listed fitment reference includes FIAT FREEMONT applications, with sample references for 2011, 2012, 2013 and 2014. Because alternator fitment can vary by engine, pulley arrangement, and mounting style, the safest approach is to match the part number DXA4177 and compare the physical dimensions before purchase.

The unit is supplied new, not remanufactured, and is backed by the stated 3 year passenger or 1 year commercial warranty. That warranty coverage is useful, but it does not replace the need to verify the vehicle application and electrical specification against your existing alternator.

At 5.84kg, this is a substantial rotating electrical component, so handling and installation should be done carefully. Before fitting, inspect belt condition, pulley alignment, and charging connections so the replacement has the best chance of performing as intended within the vehicle's charging system.

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 DXA4177 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 Brand OEX, Description OEX Alternator 12V 130A Denso Style, Adjusting Hole Diameter 12, Power Rating (Amp) 130, Pulley Section 6 Groove, Alternator Mount Single Leg, New / Reman. New, Product Group 2 ALTERNATORS.

OEX Alternator 12V 130A Denso Style. Part number DXA4177 should be checked first. Listed voltage is 12. Listed output rating is 130. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. 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 DXA4177, 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 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FIAT FREEMONT, FIAT FREEMONT 2011, FIAT FREEMONT 2012, FIAT FREEMONT 2013. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Always confirm fitment using part number DXA4177, the 12V/130A rating, the single leg mount, and the listed pulley and mounting measurements against the original alternator in the vehicle.
