Just bought my 5100's Need advice on the Rear end

I just bought billy 5100's and i am planning on getting a AAL that says to add 2'' to the back. My question to you all is if i lift my 5100's to 2.5'' and my AAL says it will give me 2'' doesnt that mean since the factory already makes the back higher then the front that after my lift my back will still be taller than the front? please help i need to figure this out to finish my purchases thank you.....

Uhhh, yeah. The rear comes approx. 1.75 inches higher. So if you lift the front 1.75 you should be about dead nuts level. If you lift the rear 2.5 then you will only need to lift the rear 1 inch max.
