Torsion twist questions

[00ExplorerSpt4x4]

I have a few questions/concerns with torsion twists. It seems to be exactly what I am looking for, a little lift for slightly larger tires and better clearance. To good to be true? First of all, Will this void Extended Warranty from Ford. I called and asked 2 different service guys and neither really had any idea what a torsion twist was (I told them to check out this site). Second concern is not only ride and handling what about steering? Any difference, more or less sensitive? Easier to roll? Recommend extended shackles or add a leaf? thanks Yall!!

I am not sure about the warranty, but in my opinion the ride is good. Body roll is reduced and steering is the same. I went with shackles becaouse I have a sport and I like them because of the increased travel. I heard the springs give you a stiffer ride, but many people have said the ride is good.

Warranty

I've read that anything that is affected by the lift is subject to warranty issues. In other words, your tire wear, bearings anything in the suspension, driveline, etc...The easiest way to get around this is to simply lower the vehicle to stock specs if you need to go into the dealership. Its a 15 minute process once you get the hang of it.
I like the ride and handling. More firm.
