hi

those cen diffs look nice for sure.


the 'old school' usual mods i and many others did to the savage diffs were the following.

- use a kyosho IF103 cup instead of the normal 'plastic' cup. so you can mount a 16x8x5mm bearing there.



- trim the ringgear so you can use a 16x8x5mm bearing there too. like serum said above.



- inside the cup trim the pins down a bit and use the little plates (here shown in a alu cup). works well in the plastic cup.



four years later hpi did the same principle to their 'new' savage x diffs.



- to take the stress from the inner bearings you can mount two additional bearings 21x12x5mm on the diff




- trim the bulks






diffs modded like this and shimmed properly hold up pretty good. of course all of this can be done the alu parts (cup, bulk etc).
i know this is all very old news but it fits to the topic here. maybe some 'new' the savage stuff havn't seen this before.
