Howdy, yes your going to have to lower your mounting point by three inches on your stabilizer to get the most out of it, breez makes good stuff from what I have seen, on your oils I have switched to mystic oil, it's red in color and is like regular gear oil, not systhetic or like the thinner stuff that gets better gas mileage or more horse power, I go for quiet and something that has shock loading for off roading, you ever give your rig some gas and then let off of it and hear a loud clunck, thats thin or too thin of oil for me, I like to have a little thicker oil in there and save my gears, I have pulled samurai transfer cases apart at one hundered thousand miles or more and the gears looked like new running the stock gear oil, I have had problems running synthetic oils in the x-fer case and the engines so i'm sticking with the more stock type oils.
