I like the oem stamped steel bumpers myself, but if I had to buy an aftermarket it would be a Warn or AEV bumper. I've owned a couple AEV rear bumpers for JK Wranglers and they've been great. Be careful to stay away from the heavier bumpers. I had an ARB bull bar on my first JKU and it was like driving around with an anchor up front! As for suspension, ARB makes good quality components (springs and shocks) for suspension as well, but for my JK I found that doing the a la cart method worked the best. I used components from several manufacturers like OME, Tera Flex, Rancho, Hellwig, Synergy and even some pro comp brake line brackets for my last suspension setup. These companies each had a few components that I felt were head and shoulders above the competition. I wouldn't limit myself to one "lift kit" but educate myself on what is out there and what components work the best together and assemble the suspension. I like to match my shocks and springs from one company but bump stops, brackets, links, track bar brackets can be pieced together to build what you want. Your goal should be to end up fitting the tire you want and have the Jeep handling better than stock.
