I just put some 315s on the expedition. I am contemplating getting the conversion kit from monroe and doing the torsion twist and rear spacer, but from what ive read i am only looking at 2" of lift. im against the body lift because of cost. Now how much lift can I get just with torsion twist and adjusted the height sensor on the air ride? I ve also read about the sensatrack 58518 giving an additional 2" longer coilover, would this coilover give me extra lift on top of the torsion twist 2"? Finnaly , will a 2 " lift give me decent clearence for the 315s tires?
