Thanks everyone. I did a search and read a lot of what was posted but wanted some more timely feedback. Brian, I have 32x11.50s on and they rub something fierce, even with the 3" suspension lift. I'm concerned it may be due to the back spacing on the wheels. So I am now concidering the BL to clear the tires and allow for a little drop on the SL to allow a little more articulation on the suspention, get the full advantage out of the SLR UCAs. It's still in the "Hmm... I wonder...?" stage since my next step is lowering the front differential. Which style of stock rims do you have Brian?
