Hey everyone i've got a question hopefully one of you have run into. I'm about to install 2 inch rear blocks, Crank up the torsion bars, maybe install a leveling kit on an 01 f-150. The torsion bars should probably give me an inch or two but what am i actually changing for added height, The lower A-arm? Done plenty of other full size trucks but not a 97-03 f-150 before. I'd appreciate any input thanks a lot.
