this may be a dumb question, but my 06 double cab has not had the TSB done to the rear suspension. I am preparing to buy the OME 3" Kit ($699). At checkout, there are two options for the rear, as follows:
-Toytec Add-a-Leafs Standard
-Toytec Add-a-leafs for TSB springs
Whats the difference between these two options, and which should I choose? I'm guessing I would need the Standard?? Thanks!
