Product overview
The DXA520 is a 70A Denso-style single leg alternator with a 5-groove pulley, suited to vehicles with a 5-rib serpentine belt configuration. The 5-groove pulley is distinct from the 6 and 7-groove units in the OEX Denso range and is used on some earlier or lower-specification Denso-equipped vehicles. Confirm your vehicle's belt rib count before ordering.
The IR11 pin code is shared with other OEX Denso units including the DXA4036 (70A, single leg, 6-groove, 163mm CTC, 55mm OD) and the DXA4041 (110A, single leg, AA section). The DXA520 is differentiated by its 5-groove pulley, 53.5mm OD and 164mm CTC. Confirm all dimensions rather than relying on pin code alone. Note also that the DXA552M (130A, single leg, 7-groove) shares the same single leg mount style and 58mm leg thickness but has different CTC, pulley and output the two are not interchangeable.
