I wanna do the Skyjacker 3.5 Sport lift from Qtec and the AEV Geometry Correction Front Control Arm Brackets for added stability. I'm gonna run 315/70/17 Duratracs on the Helo 389 wheels with 4.50 backspacing...

What else should I be lookin out for? Will i need a new pitman arm, or driveshafts? Will there be a ton of vibration once i hit 60 without the ds? I have a 2013 Sahara 2 door and the 3.6 kicks a$$ with get up and go imo, so i'm not to worried about the larger tires and lack of umph...

Any comments or opions would be awesome...

 

Having a 2dr you will need front & rear drive shafts

 

Just installed the skyjacker 4" lift on my 2011 JKU and I've gotta say don't waste your money on the pitman arm. If anything do the drag link flip its cheaper and a lot easier. Also have Gibson headers and cat back exhaust with stock 3.21's and I have no problem with the amount of power I still have. Getting 19 highway and 17 city still with the 6 speed makes me think re gearing is not for me especially because its not my DD.

 

If I didn't get the drive shafts what would be the repercussions?

 

You'll wear out your u-joints, you wont lose them immediatley, it will take time

 

Unless you get exhaust spacers your front drive shaft will rub your exhaust crossover.

 

Is this only for 2 drs cuz I don't have this problem with my 4 door??

 

It's only on 2012 & up

 

Awesome thanks.

 

You may not have to replace your drive shafts at all. The issue is the rubber boot over the rzeppa joint coming out of the transfer case can pinch against the housing causing the boot to rip. Once this happens, grease gets out and dirt and water get in ruining the joint. The rear shaft on the 4DR is at a less extreme angle, so you can usually go 4" without issue. The 2DR has a much shorter shaft with a steeper angle that gets really bad when you lift it. The front shaft has the same angle on both the 2DR and 4 DR, but is worse on the 2012 and 2013 models. At 3" or so, it is likely to pinch. If I was you, I'd look at a 2 1/2" kit to run those tires and maybe flat fenders for more clearance or an aggressive look. You won't need to worry about your steering at this height and you can probably run stock arms.

Also, Skyjacker tends to have a poor reputation. Some people love it, but I've had bad experiences with their shocks. I'd look at EVO, Rock Krawler, Full Traction, Teraflex, and Metalcloak for comparison.
