What happens is, as you lift, the track bar and drag link (which are slightly different lengths) drift away from being parallel. When they are not parallel, that's what causes a little bump steer during suspension travel. The flip kit moves them back closer to parallel at the lift heights of 3.5 and above.
Now, there are plenty of kits at 3.5 that don't do any steering correction, like the MC kits for example. 3.5 is on the fence and some need/want the correction and some don't.
Also, the other form of correction is the drop Pitman arm. If you have the better RC 3.5 Series II kit, you have the steering correction with a front track bar bracket and drop Pitman arm.
Either way, if it drives good, don't mess with it.
