Bullet proofing the savage diffs

[Serum]

The best way to go is to shim them properly and get some FLM bulkless or GPM housings; the problem with the bevel gear is it simple sits in a too flexible housing; aluminum addresses these issues.

Aluminum housings + Shimming them is the key. The aluminium cups with steel inserts help the small gears stay in one piece longer.

Another weak spot on the savage gears is that the ringgear uses a 10X16 bearing. I usually use a lathe to turn down the 10mm od to 8mm and use 16X8 bearings. The problem with the 16/10 bearing is that with these dimensions you have allmost no room for proper sized balls.

Another good fix would be to use a centerdiff, which takes out a huge amount of stress on the diffs.
