    4" and 6" are gonna need the same stuff. The usual stuff you get in a kit and a steering arm if you didn't get one. Extended brake lines, dropped transfer case, possibly some shims if you can't get good angles on the driveline.

    the only extra you need with the 4", besides the lift itself, is the drop steering arm. no extensions of brakelines, driveshafts, or fuel fillers.
    you need all of that, and maybe more, with a 6".

    All trucks/ lifts are different. I used my stock driveshaft with my 6" lift (ProComp) and just lowered the Tcase. This was with a 208 slip yolk. I had about 2 inches to spare before the shaft could slip out. But after putting in the 14 bolt, raising the truck a little, I had to get a new shaft made.

    Depends on how you set up your truck. Change the pinion angle with shims or drop the t-case, longer driveshafts aren't needed. Steering arm is a definate!

    a 4" is a good choice. I personally don't care for the RC's much, but whatever floats your boat. Most kits come w/ the degree shims. You will probably want either a 2 or 4 degree shim. Try to run the least amount of shim you can. I would say a 2 degree will work since you are probably gonna be lowering the tcase for the rear angle (this hurts the front angle). In terms of extras... you will want the old ORD Steering box for sure... the ORD sway Bar disconnects... maybe a zero rate spacer to even out the back. Steering wise get a 4" steering arm... extended brake lines and shocks.... then you should be ready to roll. I also recomend getting new shackle bolts as them seem to get messed up in the rusty removal process... oh yeah... soak everything w/ PB Blaster or equiv. for a week or so ahead of time. spray them a couple times a day to help free up the rusty, crusty bolts.

    I think the Rc's ride kinda harsh, but there are some people here that have them and like them. I have BDS springs (6") and they are great for my dailydriver/trail rig. They are flexy enough and don't have the sway like a softer springs (such as Tuff Country EZ's). Also they seem to be bigger from the factory then what they are rated (5.5" on mine) so when they break in they are right about where they should be not a half inch lower like some springs. Other then the break in they really haven't sagged since I have had mine ... roughly 7 or 8 months. My next choice would be Skyjacker softrides... a bit stiffer, but not bad at all. Much better then stock at least. Superlift Superrides also are a nice spring, but seem to be a little bit shorter once break in occurs. Overall these are just my opinion after riding in about 7 or 8 trucks of varying lifts and brands and talking to many members here. I actually chose the BDS springs unriden in on the basis of talking to Shawn. He had the Skyjacker softride before the BDS.
