Agreed, just do plenty of research cause there are a few 4" aka "glorified leveling kits" out there that give you a horrible ride and CV angles. If you go for a 4" look at Cognito ad Rancho, although Rancho looks bigger than 4".

*BDS 6.5" lift
*18x9 Moto 962 in polished black
*35" Toyo AT II's
*and a few other small mods...

exactly, plus if h&s doesn't wind up getting this figured out and no longer sells tuners it will only be a matter of time before they go out of business. then you will have an unsupported tuner with nothing to fall back on should you have a problem with it. i'd rather sit back and see how stuff shakes out.

Do the deletes...

As far as leveling, get away from it, and you will have a good ride. Running Rancho 4" lift on mine, and absolutely love it. Better than the stock ride...

leveling kit

I also have a ready lift leveling kit with the 1 inch block in the rear. My truck rides absolutely horrible, and noise coming from the front end almost as if im metal on metal....I was ready about the cognito arms kit...anyone have any input on what i can do that wont cost me a lot to make it ride a little nicer? I was told by ready lift that this kit would make it ride much better and my bars are maybe cranked up 3 turns my ass end sits higher then the front still. I need some help in how to fix this mess.

lowering it back down or spending the money to do it right is the only way to make it ride better. A good 4" lift actually does make it ride better than stock.

What about adding the cognito kit?

Leveling Kits - Upper Control Arm Leveling Kits for 2011-2012 Chevrolet - GMC - 8lug - 2500HD - 3500HD - Silverado - Sierra

Read that this would make the ride much better. Eventually I am going to put a real lift in it but that won't be for a while...for now is this a good purchase or another waste of money like the leveling kit i purchased?

the leveling kits ride stiffer because of the increased pressure on the torsion bars and the change in geometry on ball joints and tie rods
