I've never had an independent front 4x4, so I never gave a lot of thought to the way steering is affected through travel at a range out side design.
I haven't seen a lot of requirement for recalibration on the higher lifts. I would think this is because the control arms in higher lift kits correct the angle. Is it angle or added torque from the longer "lever arm" that it corrects for?
If its angle, then how does the electric steering do under more extreme articulation?
What does the calibration correct? Just the baseline angle sensors so the comp doesn't read turning input that doesn't exist?
Why not use a dropped pittman and reinforced or braced box?
