GA Cases-What diffs
 

I have an flm tmaxx with GA diff cases-Can you guys give me a good idea of some upgraded diffs to run? Someone told me the UE spyder diffs would fit,have any of you guys tried it?

I run trx based diffs in my GA cases - using flm cups and a modded ring gear that upgrades the stock 2mm screws to 3mm screws. I have a few sets of UE 6 and 8 spdyer diffs and they look to big to fit in GA cases, but I've never tried.

I went over to UE and found a thread that says the 6 spyder diffs will not fit stock diff cases. Logically if they won't fit stock cases, then it would make sense that they won't fit GA diff cases either.

I've heard great things about the UE diffs, PM Jordan he is using them on his build (I think?).

UE diffs are nothing but Ofna diffs. I have and used both 6 and 8 spyder diffs on my trucks. Buy Ofna Hyper 7/8/8.5 diffs from ebay. Cheaper than UE's.

Ringworm, I'm still waiting for the inner dimension of the GA diffs. I can tell you this though, the UE/Ofna diff ring gear is 38.12mm in diameter while the diff cup is 31mm.
