New Parts, new questions

I just got my ultimate lift kit from toytech in today, and should have some TC UCA's tomorrow so I am planning on installing my lift this weekend. I've been searching around and can't seem to find a good answer for this question so sorry if this has been answered before, but what should I set the coilovers at to obtain the 3" of lift? The instructions state they come set at 2.5" and not go tighter than 2" of thread below the adjuster ring. But when I measure them, they are already set at 2". I guess I could just install them and measure, but after hearing how hard they were to adjust on the truck, figured I might save some time setting them right the first time. Here is a picture of where they are at now...

Thanks for the Help guys

 

I would just put them on and measure first. Mine arent that hard to adjust when on the truck, you just gotta jack the front up and its alot easier.
