OEX DXA4041 12V 110A Denso Style Alternator Single Leg Mount AA Section 76mm Pulley IR11 New Unit
The OEX DXA4041 is a new 12V 110A alternator in the Denso style with a single leg mount and AA section pulley. Confirm all mounting dimensions and pin code against your vehicle's existing alternator before ordering. Note that the DXA4036 also carries the IR11 pin code - the two are not interchangeable. Confirm the mount type and all dimensions. 3-year passenger vehicle warranty, 1-year commercial warranty.
Product overview
The DXA4041 is a 110A Denso-style single leg alternator with an AA section pulley - a dual V-groove format suited to vehicles with twin V-belt drive systems. This is distinct from the standard A section (single V-belt) used on some other Denso units, and from the multi-groove serpentine (poly-V) pulley used on most modern vehicles. Confirm your vehicle uses an AA section dual V-belt drive before ordering.
The DXA4041 shares the IR11 pin code and the same single leg 165mm CTC mount dimensions as the DXA4036 (70A, 6-groove, 55mm OD). The two are differentiated by output (110A vs 70A), pulley section (AA dual V-belt vs 6-groove serpentine) and pulley OD (76mm vs 55mm). Confirm all specifications - not just the pin code - before ordering.

Frequently asked questions
Is this a new or remanufactured unit? New. The DXA4041 is a brand new unit, not remanufactured or rebuilt.
What is an AA section pulley? An AA section pulley has two V-grooves side by side for a twin V-belt drive system. This is different from an A section pulley (single V-groove, single belt) and from multi-groove serpentine pulleys (6 or 7 groove poly-V). Confirm your vehicle uses a twin V-belt drive system before ordering.
The DXA4036 also has the IR11 pin code - how do I tell them apart? Both the DXA4041 and DXA4036 share the IR11 pin code and single leg 165mm CTC mount. They differ in output (110A vs 70A), pulley section (AA dual V-belt vs 6-groove serpentine) and pulley OD (76mm vs 55mm). Match all specifications against your vehicle's existing alternator, not just the pin code.
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 (165mm), leg thickness (58mm), pivot hole (10mm), adjusting hole (M8x1.25), pulley section (AA dual V-belt), pulley OD (76mm) and pin code (IR11) all match your vehicle's requirements. Alternators are vehicle-specific - verify fitment before purchasing.
