High Steer Kit? Do I need one?

So I am confused by the advantages of a High Steer kit on a lifted 2dr Jeep JK. I have a 3.5" Rough Country lift that I added a set of adjustable forged front and rear RC track bars too. I run 315 70R 17 Extreme Country tires on a set of DC-2 wheels, a dual RC steering stabilizer, 4.56 gears and just about stock everything else. My Jeep seems to drive very well. I don't notice any bump steer or any other problems driving it. Matter of fact it seems very similar to me to when it wasn't lifted at all. Now I will admit that this Jeep is borderline a mall cruiser and rarely sees off road. A drive down the beach in Plymouth or Duxbury on a sunny day is about the extent of my off road so maybe I'm not driving it in situations where you run into issues that a high steer kit resolves? So please tell me... What will a high steer kit do for me and is it worth installing one for my use?

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.

my jku is lifted 3.5 and i do 24k highway miles a year, from stock to lifted i could feel the difference in steering quiet a bit. i flipped the drag link (synergy) n raised the axle side track bar mount and man what an improvement. i asked on the forum n was told you really don't need it but it was like night n day all said n done. only prob I had was i was using teraflex monster trackbar in the front which was making contact with my pitman arm after the bracket was raised. I use a different front trackbar now.

Ok.. I have done a little more research and after reviewing your comments on the subject I believe I have a grasp of the whole reason for the flip and how Rough Country handles it in their kit. The RC 3.5" kit I have installed handles the typical drag link flip, like the Synergy kit offers, in a different way. If you look at the Synergy drag link flip kit they use a bracket to raise the track bar end (axle side). The RC kit also does this. There is basically the identical bracket raising the axle end of the track bar. Then instead of flipping the draglink at the wheel to raise it like the Synergy kit, RC used a drop pitman arm to accomplish the same thing.
Now I understand that drop pitman arms put some additional stress on the steering box but the way I drive and use Jeep I don't see that becoming a real issue. I also understand why the bump steer problems that so many people seem to have with a lift of this height isn't a problem on mine. RC completely had this issue covered from the start.
