Yes, the hub is identical
Same 8x180 PCD and same 124 mm centre bore: wheels from Chevrolet Silverado 2500 bolt on and centre on GMC Sierra 3500 without rings. You still need to check the offset and tyres, detailed below.

Before fitting the wheels
An identical hub is not enough: offset, width and diameter change the position of the wheel, and larger calipers can touch a smaller wheel. Original wheels often use bolts or nuts with a specific seat: keep the fixings intended for the wheel, with the thread of GMC Sierra 3500 (Ecrous - 14x1.50), tightened to the torque shown on its vehicle page. Finally, check that the size is among the approved fitments for your vehicle. This comparison is for guidance only: have the fitting approved by a professional.
