I am using UE Ultralights diff cases.
So I found out the hard way that not all 1/8 diffs that the same tooth count doesnt always= dame diffs...
I had good luck fitting Ofna Hyper internals
But bad luck fitting Losi Raminator 1/8 diff internals
Just my $0.02,
Going Back to the Ofna Hyper 7's
Also I already have 1 cup for the Spider 8.
Are there any viable substitutes for the Spider 8, or do I have to hunt down a set??
