2014 silverado lowered air bag help

[skennel23]

So my truck is about to be lowered 2.5" in the rear to level it out but I wanted to add some airbags to it for when I tow that I don't bottom out. Does anybody know what kit I should go with?

It's a 2014 2wd silverado

I have this kit, but I haven't installed it yet. Still debating on whether I really need it or not. I have a 3/6 drop but I'm not towing anything.

Yea I am contemplating this kit. I will only have a 2.5" drop so I don't know if that will be enough for this kit. Some sites it says for a 4-6" drop and other say it is for a 2-6" drop so I have no clue what to do haha
