Re: Final crawl gear ratio
I have an '05 TJ with 4.56 gears and 35's and I think my RPM's are around 2600 at 65 mph. With the stock NP231 transfer case with a 2.72:1 low range my crawl ratio was about 54:1. With the new Rubicon transfer case with the 4:1 low range my new crawl ratio is about 80:1.
In my personal opinion with the 35's and running on the street I would have preferred to go a little deeper, at least 4.88's. The crawl ratio with the stock NP231 left a little bit to be desired when I was rock crawling. With the new Rubi t-case I absolutely love my new crawl ratio.
I should also mention that I have a manual transmission so that changes things too. If you have a manual I would recommend going to at least a 70:1 crawl ratio. With an automatic 50:1 might work but I'd still recommend going a little bit lower.
61 down 11 to go, almost there!
