Assuming you mean the torsion bar spacers....
Your next option is a Rancho or Skyjacker lift. Any torsion bar modified lift will result in same ride....It is not possible to lift with torsion bars and have decent quality ride. A little is alright, but near the top limits the ride is junk. Most who have done a TB lift get all excited that it looks good. Then slowly we become tired of being bounced around. Many will just do a proper lift......
I'm just going to get rid of the truck. LOL
I have same size tire. Similar height I'm sure.
To sum it up, new keys. New Torsion bars. Different set of stock keys - at the height you are now, it will still ride identically with any of the items in the summary.
