is this a good set up for my 2006 silverado? its a 1500 z71. I chose this since it will not void my warranty on any work i might need done in the future and it saves me some big bucks since its my first lifted truck. Thanks for any feedback!

3" body lift
2.5" leveling kit
33" inch toyo open country tires  

id change the tires to 33" inch bfg allterrains they have a better grip for noobies k  

id change the tires to 33" inch bfg allterrains they have a better grip for noobies k and maybe a 4inch lift thats what i got on mine and its still under wurrenty lol  

That can still affect your warranty... anything you do can.

'06 Should be torsion bar, so that nicks leveling kit...

You should be able to fit 33's with just cranking the torsion bars a little... or even with out.

I hate body lifts... just personal opinion though...  

I have an 07 classic with torsion bars.  I just had a leveling kit put in.  it raised the front about 2.5 to 3 inches.  I am very happy with it.  I have read a lot of places it is better then cranking the torsion bars.  I am told just with that I can go with 33 inch tires.  I saw it on a truck at the shop that did my kit.  I haven't gotten 33's yet, I am waiting till I need them anyway.  you should be good.  just my $0.02.  I would be interested to know if you do the 3 inch body kit how you like it.  

Tbar cranks should be avoided. I know many do them for cheap lifts but it places front suspension at or very near its extension limit. This can result in a ruff pitchy ride at times as suspension tops out a lot on extension. Plus it messes up geometry in front suspension and can cause handling and tire wear issues. When it is properly leveled (in center of travel) and aligned the unequal control arms will keep   wheel camber in proper range and also keep tread track width fairly constant as it flexes for best handling and tracking. There is no free lunches here
