Zone Level Or 2 Inch?

[gdn28]

So I just bought an 09 Sierra Wt 2wd. Now I want to play with it a little and get some bigger tires on it...after doing a little research I came across the Zone 2inch leveling kit as well as their 2inch lift kit...my question is, what is the quality of these lifts and does anybody have one of these on their truck? If so, could you please shoot me a pic. The only thing that I am questioning is the quality. The front spacer looks like it is welded and not a fully machined piece. Is this be something to be concerned about?
