2.0 bump stops 2" or 4"?

I found a deal so I might be getting some hydraulic bump stops on all 4 corners.
It will be with DMZ SUA kit in the rear and a Total Chaos 3.5+ kit up front.

They are 2.0s, but should I get 2" or 4" bump stops in the rear?
I'm assuming a 2.0 2" bump stop on the front will be good ya?

 

This is what Tim from Dmz fab told me for the rear...

"You can use any length bump stop, since there is so much up travel, it doesn’t matter much. A longer stroke bump will give you more bump control before bottoming out, while a shorter bump may keep you from having to notch the bed to fit the mounting cans. With a properly valved bypass, the 2.5 stroke bump will be fine."

 

Hummmmm I guess I should save up for some bypasses lol.
