I run the 1.5" shackle lift with cranced torsion bars (PML- poor man's lift) with a 2" Body lift. See pic in my profile. I run 33x12.5x15 tires. no problems.

If you get a full 3" lift, you will need a steering kit, which is expensive, but without it you will wear out your steering fast. 1.5" PML does not require a steering kit.

You can do 1.5" now and you can add the whole 3" lift later if you deside, as you will be using the parts that you already get for the 1.5" lift.

If you go the route of the PML for nowm you will need to get an alignment after the install, that's it. Otherwise the shackles are gonna cost you just $50.

SupaXSE, which suburb are you in?
