Brakelines are a must have at 5". Fortunately, they are fairly cheap. Just go to your local autoparts store, like NAPA or O'Reillys, and ask for 1994 Jeep Wrangler 4x4 4.0L non ABS front and rear brakelines (two front and one rear). The fronts run about $18 and the rears about $15. They are a direct swap. Also, relocate your front brake hardlines while you are at it, so the hardline is straight and runs parallel to the shock. Chances are, your shocks that came with your 3" kit are dang near the same length as stock, since most companies believe shocks for 0" lift will work up to 3" of lift, which is total crap. The stock shocks are barely long enough for even stock height, but DC didn't consider people would be flexing the heck out of their XJ's. So, I recommend longer shocks if you want to keep any kind of ride quality. Your Caster is severly going to be off due to the lengths of your control arms. Your PC lowers should be fine if the adjustment boot is shimmed out, and you may barely squeek by for a little while with the stock uppers, but I would be ready for death wobble at any moment. At 5", your stock trackbar joint will be in pretty sorry shape at that angle, plus, your axle will be shifted to the drivers side quite a bit, say 2" which will cause other nightmares, like alignment and handling, premature bushing and tire wear, etc.
At a bare minimum, please atleast get the longer brakelines, for your safety and others. Life isn't that cheap. The rest of it, well, life will suck everytime you drive that thing, whether on the street or on the trail, but the ride quality will be incentive to hurry up and get the rest of it.
