If the crossmember/torsion bars are installed correctly, the adjustment for ride height can be set in initially and left alone. ANY time you adjust the torsion bars for any reason, the alignment MUST be redone. Why anyone would want to adjust the ride height just for grins is beyond me. Set it initially, then leave it alone and enjoy the vastly improved ride quality.
