Minimum parts needed for 3" or 3.5" lift?
Right now I'm only running a leveling kit and 35s. I'm either looking at the RK 2.5" Stock Mod or EVO MFG 3" Plush Coils when they're released and build from there. With the RK 2.5" Stock Mod, I want to leave in 1" spacers all around and install the Stock Mod on top of that, so it'd be a total lift of 3.5". Could I get away with the stock front lower control arms and driveshaft then upgrade when the funds permit? And wondering about the drivability, driveshaft angles, and what other parts will be needed. Guessing longer brake lines, swaybar links, and bump stops?

A: On a 2007-11 JK, at bare minimum, you should have a set of 3" coils, bump stop extensions, longer shocks, rear brake line extension brackets, new longer rear sway bar links (factory links can be installed up front), adjustable front track bar and rear track bar relocation bracket. Optimally, I would recommend adjustable front upper and lower control arms as well as they will help you set your caster to the appropriate angle it needs to be. Also, if you have a 2-door, adjustable rear upper control arms and a new double cardin U-joint style drive shaft would be highly advisable.
On a 2012-Up, you will want to install a new front drive shaft regardless if you have an automatic or manual transmission. Assuming you install new, longer shocks with your lift, the extra droop you will see at a flex will cause the slip shaft boot on the drive shaft to tear. However, that is just one problem you will encounter. Even if you install exhaust spacers or relocate the cross over, the CV boot at the output shaft will be sitting at a significant state of pinch and this will cause it to fail prematurely.

at a minimum...
Drag link flip
Adjustable lower front control arms (EVO MFG or Curries)
rear trackbar bracket
brake line brackets
bump stops
longer rear swaybar links (move the rears to the front)
You can run the factory shafts for a little while. The front will need to be replaced first. You will rip the boot when flexing out (assuming you have the Auto)
