On torsion bar front suspension you can wind them up to raise, but do not exceed 2". Rear leaves do the spring hangers. There's a firm that makes hangers for the job, but I don't know their name. 'Red' something?
Treat 2" as the maximum to avoid other mods. Still allows fitment of slightly larger tyres that increase ground clearance.
