Im very new and not too smart with this im looking for max lift with little money, i already have torsion keys and shock brackets in front and 1" spacer in rear, but am wanting to put a little bigger tire, i have 265/75/16's right now, im wanting maybe 286/75 or 305/75, can anyone tell me if i can combine torsion key lift and a 3" body lift? also whats this i keep hearing of ford keys? do they lift the chevy more than chevy keys? any comments will help, thanks for your time
