You will bottom them out.
I installed mine about a week before my lift arrived, and it was sad.
I'm not sure how people are running the longer shock with just AALs, because the suspension is the same height as stock when compressed, which is about an inch too short for this shock.
The rear spring pack is 1.5" thicker than stock, which means the shock is mounted lower (further from the frame), and doesn't bottom out under full compression.
