Upgrading my Rock Krawler 2.5" Flex - questions
I have a 2014 JKU Rubi and currently as it sits it has the following installed:
Rock Krawler 2.5" Flex Lift (includes RK front trackbar and rear extended trackbar bracket) w/ coil correction wedges
Rancho 9000XL's
3" Bumpstops
35's (315/70/17 Duratracs actually)
My question is - if I were to want to upgrade my current lift, what are my options? How do I get my "Flex" kit to the:
RK Max Travel?
RK X-Factor?
What advantages do these systems offer over the Flex?
Any comments/ suggestion? Maybe the RK guys can chime in as well! Thanks in advance.

Go to RockKrawler.com, click JK 2.5 Flex System, write down specs. Click JK 2.5 Max Travel, write down specs. Compare specs. Order missing parts from spec sheets. Install said parts onto Jeep. Boom. Stupidly simple.

To go from the Flex to the Max Travel, you just need to add the rear lower control arms. You would also need to add rear sway links.
However, to go to the X-Factor, you need to add the upper control arms (front and rear) and add the lower rear control arms.
If you decided to go Max Travel first, then move on to the X-Factor, you have to replace the rear lower arms that were added to get to the Max Travel. The X-Factor pushes the axles out an inch for a more stock wheelbase. As such, the rear lower control arms that come with the Max Travel aren't long enough and need to be replaced.
Or you just need to get the X-Factor mid arm package that replaces all 8 control arms.
You can, and should, also replace the rear track bar.
Why upgrade? Stronger control arms that will take more abuse. Increased flex in the control arm joints for greater articulation. The more you can keep both tires of an axle on the ground, the more traction and the less need for lockers. Having adjustable front and rear gives you a better wheelbase (especially for me - I have a 2 door) and gives you the option to go to 37s with flat fenders.
