You can fit them but you will have to do a little trimming. I had 31's on mine with a BB and they rubbed a bit. I now have 30's and no rub even when I'm offroading. That is the real test they may not rub on the pavement but when you're offroad they will. I sacraficed looks for performance. Although I will be going to a higher lift in the future and 31's will be installed.

Kess, if you want lots of flex then I would go with 30's on a BB. The 31's I would considfer more for show to mild off-roading. They do fit but it also depends on the brand. ie. BGF 31's measure 30.5 I think where teh swampers would be 31.5. Or something like that.

If you cut your bumper in half, it will give you no problems, or you could just cut the bottom front corner ( you'll see when you put them on). As for the LCA's you can fix really easliy. Once you got the tires on undo the steering stop bolt, put about 2 washers on it then put it back on. Don't worry, you'll barely notices the diff. But that will keep you from turning your tires into the LCA's. As for the flex, just go to Home Depot and make some disco's, for the front. I ran this setup for about 7months and did great. good luck

What do you mean Home Depot for Disco's? I keep seeing people writing about Discos. What is it and what does it do? I am guessing it disconnects something on the suspension?

Disco's or Disconnects are attached to the sway bar so that when ou off-road you can disconnect your sway bar to allow your axle to droop and float. When you lift your vehicle you need to have disconnects because the sway bar is now that much further away from the axle. However at 2" BB I personally don't think you need them. I still run stock swaybar links at my height but I do not have a rear sway bar anymore.
Here is Rubicons page of sway bar disconnects foryou

Don't get the RE disco's yet, your just getting started, save the money. Go to home depot/lowes whatever and get 2 pins with the holes all down the side and 2 cotter pins. Take out the orginal swaybar bolts (star bolts) and put the new ones in and slide the cotter pin through. done.

Some one needs to jump in on this, my post is kinda vauge.

This is by far the easyiest and one of the best mods you can do when starting out. 5$ and 30 min. easy

Sorry forgot to add to get 1/2' washers to put on the side of the pin so it does not wear down in time.

Yes they will fit but you will be limited in clearance for any mid to heavy offroading.
