I will say that the change in height verse the adjustment nut is much more. I am also SFIFS, so I can't compare to the factory adjustment, but about 1/2 turn on the nut gets me close 3/8" in ride height change. I also noticed that I significantly bent the passenger rear lower link at some point. Like a lot....guess I will have to order the adjustable lowers from indy when tax return comes The tabs on the perches are also bent, will have to hammer them out to get the old links off. I will probably add some 1/4" plate the perches to protect them more. I also noticed that she got a good whack on the transfer case skid plate at some point, good thing I added those. Amazing how much you notice while laying under the truck for a few hours.

I wonder if the HD torsion bars will limit IFS flex because the stiffer bars won't allow the suspension to compress as much. I'm also curious how the HD torsion bars affect SFIFS... seems like the stiffer suspension would actually transfer the torsion load easier.
