Mine had to be widened 1.5"s. on each side. Some of our series had a gt4 option and had a wider rear end, unfortunately mine has it. But it has always baffled me, cuz if it was any narrower my air ride tech air bar kit would not fit, unless it is the drum and axle shaft itself that is narrower but the distance between the backing plate and the frame would have to be the same. I don't even know if that would be the difference but I just don't have an explanation of it. The only other thing I can think of is there are actually 2 different width fenders from gm and they made the axle look wider by narrower fenders???? I don't know and it has really made me mad.
