Okay I'm at about 4 1/2" of lift and 33"s. I have ran with and without and I can barely tell the body roll with or without. Some people say you will kill yourself without them and others like myself can't really tell a difference.
Brake lines are easy. Righty tighty lefty loosy. If they are rusty like mine were, Lots of PB Blaster the week before. Then 1/4 turn loose and back to tight. Just keep working it back and forth giving a good soaking of PB after you get it to initially break free. Once they are off, screw the longer ones on. Tightnen them down, secure them and bleed the brakes.
Start with Rear pass, rear drivers, front pass, and drivers front. Make sure your lid is on the resievoir, and add fluid through out the prosses. May have to do it a few times but that's the way you do it.
