Gearing advice
Okay, so project "Go really friggin slow" is in the planning stages.
I'm wanting to get gears, lockers, and a 22RE xcase to go to a 4.7:1 low range gear ratio.
My question is this: Would a 5.29 ratio be too low?
I plan on doing a body lift to fit 36x12.50's. Since I'm mathematically inadequent on all levels,
can anyone tell me what my final drive ratio would be in 4Lo?
On another note, is said drive ratio going to pose any issues for me?
I do mostly trail riding and steep hill climbs, no real rock crawling to be had in Ohio.
Thanks for any answers/advice

From Marlin's site:
Multiply your first gear, times your low range transfer case gear, times your differential gear. For example if you have:
3.93 first gear in your transmission
2.28 low range gear in your transfer case
4.10 gears in your differentials
Your crawl ratio is 3.93 X 2.28 X 4.10 = 37:1
So, just plug in your stock numbers and then your new numbers and see what the difference is going to be.
I run 35's, behind a 3.4 and a R150 tranny and 5.29 gears. My first gear is 3.83 and even though I have dual cases, running just the 4.7 gives me a ratio of 95:1. Stock was around 45:1, so a little more than twice as low.
Great for slow speed rocks... but not really what you want for hill climbs requiring any type of speed or momentum. But, in 3rd gear and 4.7 I am at 36:1 and still have two taller gears yet to go... so there is some flexibility.
I really like the control of the 4.7, and engaging the front case with the 2.28 is pretty incredible. 217:1 has to be felt to be believed. Wonderful for very technical sections that you want to "feel" your way through.
If you stall out easily now, get the 4.7. If the rocks in your area don't require as much slow speed finesse, you'll probably be happier with the 2.28 case. I think the 5.29's for 36's are a good choice either way however.
