that is so far out of what i like in a mopar, it isnt even funny
let's see, there is magnumforce, Fatman Suspension, and firm feel, all make 2 inch drop spindles
1 inch, im really not sure
they may not since it can be done by cranking the torsion bars, like you said
now...i dont know if they make em for both small and large ball joints or only large
i betcha @HemiDenny could point you in the right direction
