I run 4.56's with 36x13.50 Iroks. It comes out to being really close to the original ratio of 3.50's and 28-29". But I've considered going to 4.10's and lowering the transfer case ratio to get the crawl back.
When figuring crawl ratios you need to figure in the torque multiplication of the torque converter.
C4 1st(2.46) x Torque converter multiplication (2.5) x T case (2.46) x axles (4.56) = 68.9:1 ....Hmmm really close to the NP435 aint it...
