The 7-8" of lift would be a combo of lifts. It would take a 4" susp. lift, with a 3" body lift, a 1.5" ball joint lift, if needed you could then crank the torsion bars another 2" to achieve the 10" of lift. You would then have a truck that rode like hell and handled even worse.

What size tiore are you planning on running? Are you going to actually use this truck on the trail, or just araound town? These are questions that need to be answered, since a truck as tall as you are suggesting has no purpose being on any trail, it is unsafe.

More than tread lightly. Leave it like you were never there, nor anyone else.
