Thanks for the info. I was thinking of going with RC. Are there any major disadvantages using a bottom mount RC type kit vs. a top mount like Motofab?
On a related note, the current difference between my rear and front spacing on my stock '17 Sierra Z71 is about 3.5". Is this typical?
Distance measured from the bottom of the wheel well to the ground is 39.5" in the rear and 36" in the front.
Regardless, I'll likely still go with a 2" as I don't mind a slight rake and I often have the bed full of tools which will drop the back a bit anyway.
