Depends on what tire size you're running if you're gonna lock them up or not. I couldn't lock up my 38's with stock rear brakes if I tried ( I have). I took my LSPV out, it's easy to do, just ditch the line that returns to the front "t" mounted on the frame inside the passenger front wheel well. It's the line on the T that faces the rear end. It's behind the 90 degree fitting. Cut the line and weld the flare fitting or the line shut (it's steel) and you have no LSPV.
