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.
