Rear Bilstein 5100's with a 2 inch AAL.?

You are right in the middle there. Depending on your driving style, you would probably be good with the 0-1.5 but you will want to check your extended length to make sure you don't over extend the shock.
If you do the 2-2.5 you will want to check and modify your bump stop if necessary.

 

^^^ this helps. going with this setup very soon... been debating extended (B110's) vs. standard length 5100's for some time. since the extended would probably require some large bump stops and extended brake lines just for an AAL, I decided to go with standard 5100's. If I upgrade to full leaf packs, like Dakars, I'll probably upgrade to the extended length shocks.

 

Is there a way to run the extended 5100s and 2 inch wheelers add a leaf with the stock bump stops? How would you modify them in order to run them with the extended 5100s?
