This picture here shows the smallest diameter of the shaft at 1.055". Now the rest of the shaft is much larger as you move out towards housing ends(1.480). Does anyone have a a-body 8-3/4 shaft to measure the smallest point?or a 7-1/4? Just curious, got to say I started pulling out axle shaft thinking wow this looks stout. Then it necked down a bit. I still have no doubt this should be a strong setup. But with some MT sportsmans and eventually a stroker, the axle shafts do seem like they would be the weakest link. Only time will tell..
