Is 3" too much lowering on blocks?

[Leviticus]

Hey guys,

I am having my lowering blocks made at my buddies fab shop, I am having him make a 2" kit out of thick wall 2"x2" square tubing. And then 1/2" add on blocks out of 1/2" flat bar.

So my question, is going 3" on blocks going to cause any issues you know of? Or will anything need to be changed? I have seen some guys do it with bagged trucks but mine is all stock height right now. Cause man does this truck sit all stink bugged out (raked) right now, I don't think that 2" is going to do much or get me level.

Thanks guys.
