Like 14 sport said, no control arms, just springs, front track bar, and rear track bar bracket. I'm starting to really see the advantages to adjustable LCAs though.

How does it handle at speed ? The stock mod is a very basic kit... I usually recommend the flex kit which includes front lowers (for caster) Geometry brackets are another option and cheaper. You could also do front uppers but i would not go with RK's (too long), you want a upper that will adjust shorter than stock. Synergy and MC arms will.
You just brought up a point about the CAs that I have never heard though. Would I only need shorter then stock uppers if I am not replacing the lowers as well?

For the rear trackbar, you already have a raised bracket? Put an adj trackbar lower down on the priority list.

slap on some TeraFlex sport fixed lower control arms and that will give you about perfect caster for a RK 2.5" lift. I have been totally satisfied with mine and at about $165 hard to beat. Mine drives and tracks straight and one finger steering at 80mph.

Correct. To raise the caster, you would use either longer lower arms or shorter upper arms. One note though - with taller lifts, some mfg's upper arms will not adjust short enough to raise the caster to acceptable levels. Should not be an issue at your height, just worth mentioning.
For the rear trackbar, you already have a raised bracket? Put an adj trackbar lower down on the priority list.
It's a relocation bracket, so I'm assuming it raised the TB. I really wish I could have put the lift on myself so I would have more knowledge on how everything went together, but a sloped driveway probably isn't the safest place to have a vehicle on jack stands. Haha! Plus a little under $400 with alignment couldn't be beat.

Definitely have to look into those...I never realized how much more flex you can get out of flatties. I put mine on ramps to "flex" and my rear was almost stuffed...sway bar was disconnected though.

I have got a 2015 JKU Sport. I recently (3-4 months) installed the Rock Krawler 2.5 Stock Mod which comes with an over-sized adjustable front track bar.. I have taken it off road twice since. This last outting was muddy...all this central Florida rain. Anyway, while washing the mud off the under side, I noticed the front track bar is rubbing the front pumpkin (differential cover). I placed a pair of ramps, your typical black plastic ones from parts stores, one on the driver side front and one on the passenger side rear to replicate a "flex" in my driveway. It wasn't quite touching yet, but was within a .25". Any recommendations, drop brackets? or can the bar be rotated slightly out to clear the pumpkin without effecting geometry?
Sorry if there is a thread already started about this, I couldn't find it.
