Your burban is heavier, I would consider using a little heavier for the lowers. What are you doing with it?

im puttin 60s in i runnin 44s coil front and back

alot of factors need to be considered, weight, length of links, highway trails or rocks, sounds like you may be in over your head but if it were a 5k rig on standard trails and no rocks i would look into 2.5x.25 dom but biggers better if its within budget...
