question about lifts

I really hate admitting this because I know I will sound dumb but I need the question answered...

I am ordering a toytec 3" ultimate lift kit. When you can select the type of lift you want in the back it gives you the option of a 1 1/2 inch lift for TSB...I read a little about what TSB is, do i need to select this option or am I fine going with the regular AAL?

I have a 2011 Double Cab, 4x4, long bed, TRD Sport

Please help!

 

If you had the TSB done, than you need the 1 1/2 for the TSB, the other would be for a stock truck.

 

I have done nothing to the truck yet, so I am fine going with the regular AAL then?

 

To get the TSB leaf pack though you would have had to complain to a dealer about your truck bottoming out and they would have swapped them out. I'm guessing you'd remember if you had that done

Assuming you haven't, go with the regular AAL.

 

sounds great, thanks for the help!
