Re: 4:1 t-case...
I belive you are thinking of 4:16 tcase right? what most vendors do is use a part of the countershaft gear and two
other gears from a sj410 and mate them up to the sj 413 tcase to give you 12% lower high and 84% lower
lowrange. there are a few sites out there on how to do this. It is really out of the realm of home shops unless
you have a lathe and are a machinist.
