Diff questions

[lincpimp]

Ok, so the Gpm are lighter than the flm. I really like the flm quality, are the gpm parts comparable? I will most likely buy the flm parts for my flm tanny forward build, and keep the stock plastic bulks for the basher. I know that the heavier truck will be much harder on diffs.

One the subject of ring and pinion sets, are the savage ss metal cased diffs good enough, or should I upgrade them too? Is there an upgraded ring and pinion available, or will a std buggy diff gear set (ofna, etc) fit? The ofna diffs use the 6x16 bearings, so that would be a way to upgrade?

I will try the flm 7075 cups in the basher and see how they do with the stock plastic bulks. I do have a set of the hardened hb internals, will they fit?
