Re: adding inches to 4 inch lift
I have an 01 jeep tj 6 cyl. 5spd manual
I'm down here in Florida, so there's not really any rockclimbing going on
with me, mostly mud and sand.
I'm thinking that I may just stick with the 33's for now, or at least until
they wear out, but they're almost new. With the jeep I have and the 4.56
w/33's... How many RPMs will I be turning at 70? People drive crazy here,
I have to keep up.

RPM = gear ratio x mph x 336 / tire diameter.
So in your case 3250 RPM without overdrive and then multiply that by the
overdrive ratio of the trans. It is usually about .7, so you should be about
2275 RPM

Re: adding inches to 4 inch lift
To be a bit more accurate, the NVG3550 has a 0.78 ratio for 5th and most
brands of 33" tires are actually around 32.8" when new. So, with a 4.56
diff, Troy's I6 would be turning 2550 rpm at 70 mph. Right now, with his
4.11 diff, it should turn 2300 rpm @ 70 mph. If he up-sizes to 35s,
he'll turn 2400 with 4.56 or 2570 with 4.88 (70 mph).
