Your cv angles will be bad, this is not for 4x4 boosted launches or people who use 4x4 at highway speeds.

Lower the rear. remove a few springs from the pack and that might help.

I have them with the dual shock hoop. The torsion bars are fully cranked and I don't have outrageous angles by any means. Now when i cranked the torsion bars before the UCA's and shock hoop the ride was absolutely terrible due to the shocks being at there limits.

One last thing if you live anywhere that gets any kind of snow where they use salt or anything like that stay away from the uni-ball setup. I wish I had researched more on them. I maybe have 20,000 miles on them and I have to replace the uniball at $80 a piece because of slop in them. Honestly just stick with the ball joint uca. They are much cheaper cheaper for a new balljoint and more reliable in the long run IMO.

I have them and raised one inch over stock keys leveled, whatever that would be over stock height (2 inches?)
The cv angles are fine, I thought the tierod angles were a bit much though.

A UCA cannot make the geometry of our IFS trucks better. The only thing I like about the cognito UCAs is the balljoints. Other than that they do nothing IMO
