I decided to try lowering my hardbody with the torsion bars and it worked. It was sorta difficult since the threaded bolt was so long i couldnt find a socket long enough, i hat to use a regular wrench. It took about 80 small cranks(thats the furtest i could turn the wrench b/c of the bracket) and that brought it down around 2 inches. Havent bought the blocks yet for the rear but they will be in soon. Ill do final front end adjustments after i put the 3" blocks in. Good Luck, oh yea it took maybe 1/2 hour including setting the truck up on the jack stands.

This site will be helpful when i do the blocks. the torsion bars was basically experimental since i couldnt find any info on specifically how to do it.
