Thanks, hope hear from u soon.
4.56 will be a good fit for 33-34" tires, you said you are currently on 31"s, 4.10/11, would be fine if you don't go above 32". If you do,and as stated most likely you do, have the Dana 35, some will stay don't upgrade the gears, just replace the axle, I say its up to you, there are much stronger options out there.

2: size of tires
-- Are going to increase your tire size? You currently run 31" tires, if you're not going to increase tire size I honestly wouldn't change the ratio. You could have better gains else where for less money. If you're going to increase your tire size let us know what size you will be running then we can suggest a gear ratio.
3: as 5-90 stated engine size
4: as 5-90 state transmission, automatic or manual

or something similar, its not a bolt-n-go option, some fab work involved, but still a good option nonetheless. Chrysler 8.25 (97+), is a bolt in option, and an upgrade, can be found very reasonable.

3.55's are 3.55's exactly the same, what you will get is a stronger rear axle. there is no need to swap the front axle. however if you do regear the rear axle you have to regear the front to match.
