I've got a 2" lift on mine OME is the kit I went for.
You need 4 springs and shocks. You don't need anything else for a 2" lift.
You don't need any special tools and you can change the springs without spring compressors, you just drop the axles pull out the springs and swap them over.
ONE THING TO REMEMBER. OME rear springs are different lengths they are maked A & B and A which is longer goes on the drivers side.
