As long as we're talking, will we have to alter our drive shaft?

I'm starting to feel a real need.

with the additional length of the doubler you would have to stretch the front and cut the rear shafts

That being said, it might be enough to snap an axle which would necessitate a "mod" called new axles!

Your tcase + doubler ratio would be ~7.4:1 * your first gear * your axle ratio and that'll give you your crawl ratio.

There is part of me that wants one, and another part that says thats a little to slow for even me.
