I believe Zone has the specs on the website for the alignment. I will tell you that with those 36" Duratracs you will need to do some extensive trimming! I have 35's and had to do a lot in the front and back. I still get a little rub in reverse at just under full lock. I'm glad I went with the 6.5"... 7-9" might have been better to avoid any rubbing. Also make sure you throw the zone add a leaf in yours, especially since it's a crew cab. I'm glad we did. It doesn't cost much.
