OK so my Rubicon jku will br here in roughly two weeks. I'm having trouble deciding between the teraflex 2.5 with bilsteins 5100 or rock krawler 2.5 stock mod w 5100 bilsteins. I'm leaning toward the rk but the kit doesn't come with any brake line brackets or bump stops. Do I need them? It does have an adjustable front track bar which I like over the teraflex but the teraflex seems to have a more complete kit addressing the brake lines and bump stops. Also the rk has front progressive springs which the teraflex does not. Will the progressive springs have a tendency to sag quicker if I install a bumper and winch? Your thoughts/opinions would be greatly appreciated!
