Bullet proofing the savage diffs

Can anyone give me the ultimate recipe for bulletproofing my savage diffs? I just converted my savage with the flm kit and am running a 4s 6000 polyquest and an MMM 2200kv combo in it and it blew the rear diff in less than 2 runs. Fun as hell though besides that.

Well I have the savage flux on 6s, and already screwed up a stock bevel gear so I switched to a nitro bevel gear and added a shim. I did backflips till I was bored of them, and am kind of curious as to how long it holds up. Only have a few packs through it.

That shim is the key. I'd add shims to the other diff as well.

I am thinking eventually I will do the CEN mod, but like I said I am interested to see how long this lasts. Standing backflips are not easy on gears...

It would be great if they listed the part#'s of the cen diff gears you need, or better yet a complete parts list including numbers for everything that is needed.

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.
