The OEX DXA4090 is a new 12V 120A alternator in the Denso style with a pad mount configuration. Confirm all mounting dimensions and pin code against your vehicle's existing alternator before ordering. 3-year passenger vehicle warranty, 1-year commercial warranty.
The DXA4090 uses a pad mount rather than the leg mount configuration found on most other OEX Denso alternators. A pad mount bolts directly to a flat mounting surface via a solid pad base rather than through separate mounting legs, and is common on certain commercial and industrial vehicle applications. Confirm your vehicle uses a pad mount bracket before ordering.
All mounting dimensions, pin code and pulley configuration should be confirmed against your vehicle's existing alternator before purchasing. The IR89 pin code is specific to this unit within the OEX Denso range covered in this session.
New unit: Brand new, not remanufactured.
120A output: High-output alternator for vehicles with elevated electrical demands.
Pad mount, 180mm CTC, 69mm inside leg, 72mm leg thickness: Pad mount configuration. Confirm all mounting dimensions against the vehicle before ordering.

9mm pivot hole, 8mm adjusting hole: Confirm hole sizes suit the vehicle's mounting points.
IR89 pin code: Confirm pin code and all dimensions against your vehicle.
Internal regulator: Voltage regulation handled internally.
Non-insulated return: Earth return is not insulated. Confirm this suits your vehicle's wiring configuration.
3-year passenger / 1-year commercial warranty: Extended warranty for passenger vehicle applications.

What is a pad mount alternator? A pad mount alternator bolts directly to a flat mounting surface via a solid pad base rather than through separate single, twin or quad mounting legs. This configuration is common on certain commercial and industrial vehicle applications. Confirm your vehicle uses a pad mount bracket before ordering.
What does non-insulated return mean? A non-insulated return means the alternator's earth return path runs through the chassis rather than through a dedicated insulated return wire. Confirm this suits your vehicle's wiring configuration before ordering.
What is the warranty on this alternator? 3 years for passenger vehicle applications, 1 year for commercial use.
What should I confirm before ordering this alternator? Confirm mount type (pad), CTC (180mm), inside leg (69mm), leg thickness (72mm), pivot hole (9mm), adjusting hole (8mm), pulley section (6-groove), pulley OD (50mm) and pin code (IR89) all match your vehicle's requirements. Alternators are vehicle-specific, verify fitment before purchasing.
