Your truck most likely will qualify for the TSB...however the TSB is NOT a lift-It will give you between 1/2 and 1 inch in the back.
If you get the TSB- You'll have to do some extra work with an AAL to get the full 2 inches.
If I were you...I'd skip the TSB and get the AAL....It's what...70 dollars or so.
I agree. Get the AAL instead. I got the TSB done and bought a ToyTec
AAL. However, to get the AAL to work with the TSB springs, you gotta kinda "make" it work. Chris4x4 says that they will work with the TSB springs, but you either have to install them backwards or cut about a 1/2" off the AAL. For that reason, I haven't tackled it yet.
As a side note, I have an '09 and the dealership didn't even blink about doing the TSB for me, although I think this is a dealership by dealership thing. The '09 isn't officially included in the TSB - but I checked my springs and the part numbers matched. It raised my back almost a full inch, but it will settle.
