, that's way too much for a 2DR and the majority of the 4DR run 3.5" to 4"In the Sitcky JK FAQ it says
Q: What are all the components that I will need with a 4" lift?
A: For a 4" lift, you should have a set of 4" coils, bump stop extensions, longer shocks, extended brake lines, longer sway bar links, adjustable front track bar, adjustable rear track bar, front and rear track bar relocation brackets, dropped pitman arm, adjustable upper and lower control arms front and rear and new double cardin u-joint style drive shafts.
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.
as far as 1310 or 1350. i have a stock motor and run 35's. my coast 1310 has given me no problems. if you have swapped in a v8 you should start looking at the 1350's because of the increase in torque and horsepower.

I am running a 2014 rubicon with 37's 5.13 auto 2 door with about the same amount of lift. I opted for 1350's front and rear In case I ever go 40's. I had 1310's on my old 2010 with the same setup just a sport and never had any problems
Good info! if anyone should know it should be the guys who make them.
