imo the "evolution" of the savage diffs since the legendary savage 21 in 2001 (? or was it 2002) showed up went through several steps.

- the 2 spider diffs were upgraded to 4 spiders
- after that the little sliding blocs were introduced to prevent the cross shafts to work into the plastic cup. today these sliding blocs are usual in traxxas and hpi diffs in their monster trucks. this could be done with the plastic or the aluminium cups.
- the hpi cup was replaced with the kyosho part IF103 (uses a 8x16mm on a steel ring)
- the 43T gear was modified to accept 8x16mm bearings.
- later the outer-bearing modification was done to further strengthen the diffs and reduce the load on the inner bearings.
- several aluminium cups were offered in the tuning market since nearly the beginning
- the 43T bevel gear and 13T were hardened and called "heavy duty" etc etc
- with the savage flux the bulled proof diffs came with the 29T and 9T gears.
- of course various combos of the different mods were done.

here some old pics of some mods done to savage diffs.

a GH alum. diff cup


here a maximizer alum diff cup, the small sliding blocks, and prepared diffshafts to accept the outer bearings


prepared diffshafts


bevel gear with 8x16mm bearing


IF103 diff cup with 8x16mm bearing


diff with the inner and outer bearings


prepared bulk for the outer bearing, of course you can do this with alum. bulks
