Torsion bars
 

93 Z71. I Added new lifting keys 3yrs ago. Right side has dropped 1". At that time I also added 2" lift blocks under rear springs.
I now want to go back to the stock height.
Can I just put the old keys back in and turn the torsion bars back down???
(At this time I will also remove the 2" blocks in the rear.)
Thanks for any help. (It just hurts me now to much to crawl up into the truck)LOL.
