    This is from the PlanetZU article:
    "The purpose of this modification is two fold: Increase suspension down-travel, and improve the alignment after lifting. When the torsion bars are cranked, some amount of negative camber is induced into the steering geometry. This is just due to the design of the IFS system. Under ideal circumstances there should be a slightly negative camber. Too much negative camber will cause uneven tire wear, and will also decrease the traction, mostly during cornering due to the tire having a poor contact patch. By flipping the ball joint, or flipping it and using a spacer, the camber is moved back toward the norm, which is much closer to 0. Depending on your specific setup, it may go back to perfect alignment, or not, but you should have the truck aligned after front end suspension changes anyway."


    I guess we're both right.
    Would a BJ flip be better so you don't have to crank the torsions as much, thus reducing the stiffness in the IFS front end?? My experience in my Toyota truck 4x4 days with IFS is the more you crank the torsions, reindexing etc. the stiffer the ride and sometimes to a point the shocks barely do any work. Also, with a BJ flip, you have to cut the snubbers or replace with low pro ones to gain the down travel?

    Same thing with Isuzu, I installed the body lift so I could lower the suspension becuase it got really stiff at 4" IFS lift.

    The BJ flip won't cause lift because you flip the top BJ and the lift comes from the lower A-arm. Addtionally, you don't need the low profile bump stops since the BJ flip mounts the spindle a 1/4" (?) lower. Low profile bump stops will give you another 1/4-1/2" down travel.
