If you already have a 2 inch body, you could get the rubicon express extreme duty 4.5 inch suspension lift for about $900 and fit 37's easy and still have plenty of room for articulation. The kit comes with everything but shocks, and it is really easy to install yourself.

 

Too bad you'd need different axles, gears, etc. You're lookin at some money when you go that big.

 

thanks a lot guys
