The shocks on a Crossfire are separate from the spring (unlike any strut equipped car) and changing them does not (and cannot) affect ride height or alignment settings.
That said I have seen brand new gas struts (on a strut equipped car) initially ride a few millimeters high (10mm or so) on cars where the strut (shock absorber) was really worn out, though within a hundred miles or so the car has settled down to normal.
