on the lower control arm where the torsion bar sits there is a single bolt. you turn that bolt and it will raise or lower the front end. but that is it just one bolt on either lower control arm it's about a 3/4 in size.
I don't have a direct answer, although it is usually a simple tightening of the torsion bars. Be careful - vehicles are designed for their ride height. It can cause all sorts of geometry issues if you lift them much.
