Done a couple 4" lifts & here's what I had to do: driveshaft should be fine,but mine were LWB trucks,changed to a raised pitman arm,brake lines were ok,but may depend on your application.The 3:08s might be too much for the 33s,but again depends on your wants& needs.If I missed anything,somebody will jump in...
