Started at 4.38mm ended at 4.28.
Its great to have that smoothness under load of the Xray diff now available in the Awesomatix. I've long felt Xray have the best diff. Maybe the NT1 metal gears will fit too.
Please check the length of your cross pin.
It should be short enough ( ~10,4 x 2 = ~20,8mm) for free movement in the slots after screwing of the diff's cases. This is very important!
All our test diffs are smooth without any sanding of the original gears ( ~ 4.35mm thickness). Our big washers are 0,3mm and small washers are 0,2mm in thickness.
