Re-gearing question: 37's with 5:13 or 4:88 gears?

[Escape.idiocracy]

Currie explains their fluid choice here:

Bad gear setups.

There are tons of people running 5.13 and 5.38 with no problems. People have been running these ratios in street driven Jeeps since overdrive transmissions came out.

Hey thanks! Their page looks totally different now, and I see they have changed to GL6.

Edit! Man I was totally backwards!! GL5 will void their warranty!

Good to know actually. I was basing this off the popular regearing calculator in the forums. 2500rpm is where I would like to be in 8th.

What tire are you running?
