GMT-900 Z71 Suspension Height?

[c0boy]

After searching I have yet to find a definitive answer. When you search for some leveling kits you find that the company says "Not for use on Z71 Suspension Trucks".

 

So what is the difference in height? I can only assume Z71 is taller so that some parts may lift it too much?

 

Thanks

I'm not aware of any difference between a z71 and other gmt 900 trucks besides shocks and skid plates, I have done a 2" level on two GMT 900 4x4 z71's now without issue. The k2xx trucks may be a different story because of the different control arm styles, but I'm not really well versed in those models.
