    depends on how you plan on using the truck, and if its your trail rig or dailly driver, also what kind of tranny you have. guys who run mud dont mind mild gears because you need alot of wheel spin and rock guys like deep gears so you use as little throttle as possible to stay in control. if you have a overdrive tranny you can offset deaper gears for dailluy driving,but if you only drive it on trials who cares how fast you can go? also you will prolly get tired of 35s and want to go with bigger meats in the future so then you run into problems like running 40s on 4:10 gears (oops i'm doing that) and have to spend the money to regear AGIAN. hope this might help

    4.56 and 35's work together really well, plus you can get away with38's in the future if you wanted /forums/images/icons/grin.gif

    I run 35's and 4.56's. It's very quick off the line, especially with my worn down 35's.

    To do the swap your perposing, (if you already know the terms I'm sorry), You will need new carriers, which the ring gear bolts onto and is your actual differental. An install kit, which includes all the bearings, marking compound, shims and bolts. And a gear set, ring and pinion. To do the full swap in a housing that was 3.73:1 I don't think you would need carriers. The carrier in the front you already have maybe usable for 4.11:1s. I'm not sure.
