Anyone having Savage diff problems?

[MTBikerTim]

I haven't had too many problems with my savage diffs but I decided to beef them up anyway. Seeing as though some people here are going to be running 1521s I can see a need for stronger diffs. I haven't actually run these yet so I don't know how well the hold up but I have never heard of anyone who has done this mod break them.



Basically they are Cen GST diffs with savage output shafts. They fit almost perfectly. You can see in the picture the savage diff teeth (on left) look tiny. The pinion needs to be shimmed out by a little over a mm and the drive pin holes in the output shafts need to be enlarged to 3mm and that's about it. The drive cup on the pinion also needs to be secured by a grub screw too instead of the savage screw in pin. The other benefit of this mod is that the bearings on the outputs are larger on the Cen diff and are less prone to failing like they do on the stock diffs. These diffs are also really cheap on ebay.
