OEX DXA4090 12V 120A Denso Style Alternator Pad Mount 180mm CTC 6-Groove 50mm Pulley IR89 New Unit
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.
Product overview
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.
