Couple of things I found out.

If you crank them up too far, you'll be topping out the shocks, meaning they don't have much travel upward.

I cranked mine about 4-5 complete turns and it wasn't enough.

Then I put in a set of Ground Force drop shackles that did the job pretty good.

 

Yea, I've found anything more than 2" of lifting the front and the shocks can bottom out fairly easily off-road or even going too fast over speed bumps. 2" really looks a lot better than stock, but it's not perfectly level, it really takes 2.5" to get it perfectly level and that's asking a lot out of a t-bar crank. If you want it perfectly level AND plan on off-roading, then I'd strongly suggest a level kit and if you don't also plan on new, longer shocks, then get a kit with the relocation brackets.
I just think the t-bar crank is a nice FREE way to get a little better look and clear a little bigger tire.
Personally, I'd never do thedrop shackles thing. But that's just me, I just don't believe in lowering anything, ever!!!

 

some have gotten away with not getting new shocks after a leveling kit......but i dont have new shocks and i got a 2.5" leveling kit...and damn do you need new shocks. after tires.....maybe even before, longer shocks are going in!
