Need a shock with enough travel for my setup...

I have a FabTech 6 inch lift with 5100s set at 1.75 inches. alcan is making me a leaf pack to lift the rear 8 inches getting rid of the block that was installed with the lift and matching the extra 1.75 i have in the front due to the shocks. It will probably be 9 inches total because they are giving me 300lbs over stock for my load capacity so i'll have an inch of positive rake in the back or so. i need a shock that will travel. i know nothing about the shock world when it comes to good bad and what works. i have bilstein in the front but could care less what goes in the rear as long as it is a good product. my main concern here is fit and travel. Bilstein 5160s all say for toy tacoma with 0-1 inch of lift leading me to believe there isnt going to be enough travel.

enlighten me people!
