Product overview
The DXA4056 is an 85A Denso-style single leg alternator for vehicles with standard electrical demands. The IR115 pin code is shared across several OEX Denso units - confirm mount type, CTC, leg thickness, pulley section and all other dimensions against your vehicle's existing alternator, not just the pin code.
If the application requires a higher output and the 85A unit is being replaced with a 130A (DXA4006 quad leg, or DXA4000 twin leg) or 160A (DXA4034) unit, the battery cable and fuse between the alternator and battery should be upgraded to handle the increased current. This is a supplier recommendation - consult a qualified auto electrician if unsure.

Frequently asked questions
Is this a new or remanufactured unit? New. The DXA4056 is a brand new unit, not remanufactured or rebuilt.
If I upgrade to a 130A or 160A unit, do I need to change anything else? Yes. The supplier recommends upgrading the battery cable and fuse between the alternator and battery when upgrading from an 85A unit to a 130A or 160A unit. The existing cable and fuse may not be rated for the higher output current. Consult a qualified auto electrician to confirm the correct cable gauge and fuse rating for the upgraded output.
The IR115 pin code appears on other OEX units - how do I confirm this is the right one? The IR115 pin code is shared across several OEX Denso alternator units. This DXA4056 is a single leg unit with 163mm CTC, 58mm leg thickness and a 7-groove 58mm OD pulley. Confirm all of these dimensions against your vehicle's existing alternator - pin code alone is not sufficient to confirm fitment.
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 (single leg), CTC (163mm), leg thickness (58mm), pivot hole (10mm), adjusting hole (M8x1.25), pulley section (7-groove), pulley OD (58mm) and pin code (IR115) all match your vehicle's requirements. Alternators are vehicle-specific - verify fitment before purchasing.
