If you are referring to the “torsion key” type lifts, they don't do anything that you couldn't do just by cranking up the bolts on your torsion bars yourself, unless you have already cranked your stock keys to the max. Cranking up or replacing your keys does raise the front end up, but it has the downside of accelerated wear on the ball joints, CVs, etcetera. It becomes a tradeoff of height versus longevity.
If you are looking at one of the kits that actually comes with new control arms or other items designed to correct the ball joint angles or CV angles, then that is a different story.

I wouldn’t install a new torsion key until I had first just cranked the torsion bars. Despite what anyone will tell you, there is no difference between cranking the torsion bars versus leaving them un-cranked and replacing the keys. One is free, one isn’t. Either way you will probably need an alignment afterwards.
To make your front end components last as long as possible, you typically want your CV shafts to be straight across from the differential to the wheel. Cranking the torsion bars higher will make your cv shafts operate at an angle. This increases the stress on them, and is compounded by when you turn the wheel. Also your ball joints aren’t designed to operate at these higher cranked angles, so you will accelerate the wear on them as well. Lastly you are changing the path the suspension travels based on the arcs the control arms are following, thus usually when you crank higher the ride will get rougher.
The general consensus is that 1” of crank (usually takes about 6 turns per inch) isn’t too bad, 2” will really start to wear components out quickly, and more than 2” is asking for trouble.
In fact most of the times you can get more lift out of your torsion bars than you need, and replacing a key will just allow you to crank more than you need to.

upon doing further research, my suspension setup will be ford F150 keys, a moderate sway bar, new rear springs, airbags and spacers. going to add monroe reflex shocks, as wells as a new set of cv joints and ball joints to replace whats there. and a steering brace and stabilizer.
it wont be getting pounded to peices off road, im gentle on my rigs...but want the extra height for tires.

I have an 05 Z71 and after reading a ton of threads and reviews, and seeing just as many pics, that is exactly what I plan to do as well. Well, at least as in the general sense. Shocks and other brands may vary for me. The next good option is a 6" lift, but IMO that's a little too redonkulous on a Suburban.
I don't really care for the bro-dozer look.

Consider a zone 1.5" body lift as well and you can run 33s easily
Yep, a couple of inches is enough for me too. My jeep jk only has a 2" lift and that's plenty too. Having 2 expedition worthy rigs is great tho. Can't wait to get the suburban rockin. Chili, it's worth using the reflex monotubes. I have them on my Jku, and they are awesome.
