So I found these torsion bar keys on ebay. They claim to lift the front end 1-3'. Has anybody tried these yet?

 

Try searching in the Lifting Tech section. Keys really won't help the fact that the suspension geometry goes way off with that much lift and no modification of the suspension arms, etc.

You can get 1-1.5" lift by just cranking your torsion bars as they are now...

 

appreciate it brother. Thinking longer control arms, torsion bar keys and rear add a leafs aughta give me about two more inches all the way around. Allready cranked up the torsion bars.

 

What you have to watch out for is the half shaft angles. Lift puts the CV joints at higher angles, causing more stress there as well.
