You can get that much lift by cranking up the stock torsion bars.., Ive done it on mine.., brought the front up an Inch, and a Half..., Im now clearing 295 B.F.G A/Ts (33.5 inch tall) Tires.., on Weld Stone Crusher Wheels.., It rides a little firmer., but not that much differant, and the front end came right into alinement with no problem.. I did need to do a little trimming on the cladding., and a little massaging of the front wheel wells., not much though., and not noticeable... Butch, Black Z71., Cat back exhaust, Hypertec Power Programmer, Volant intake, tail lite Blackouts, Wood Dash Kit.., still to come.., some cladding painted to match, New stereo.., and a Supercharger.
