good choice in building... i have the teraflex 3" on my red rock crystal with the RR XHD front bumper... and will be purchasing the mopar off road bumper with tire carrier for the back as soon as I can afford it

 

The Mopar rear bumper is very heavy and I lost about 1/2" in the back when I installed it. My rig is still leveled since I installed a winch with the RR front bumper at the same time. You might need to add coil spacers in the rear if you don't plan on installing a winch. I also reinstalled the factory rear coil spacers on top of the Teraflex spring isolator that came with the kit.
