Rear spring TSB on my 2011 - just made appt

I just called the dealer. I made the appointment to have my rear springs looked at to see if I can have the TSB done. I want to put the billstien 5100's up front to level up the dropped nose from the settled suspension. They set me up to look at but not sure if my truck is affected. I hope it is. I don't want to have the front done until I know for sure what will be done with rear.
I know some of you others that have 2011's have had it done without troubles from dealer.
Wish me luck.

If they don't do it, just call the 1-800 number and say you're having a problem. They give you a reference number, then you give that to the dealer. At least that's what I did.
