Alright guys called the dealership today and gave them my vin and it does have the LSD.
Having my gears installed wednesday and was told I should have new clutches installed in the LSD so I am going to do it for piece of mind.

 

Sounds good. I havent heard or many guys rebuilding the stock LSD so I would be interested in hearing the cost associated with it

 

Its actually fairly inexpensive,165.00 compared to the 400 to 500 for the auburn and it does the same thing,granted it probably isn't as strong as the auburn but I will not be taken my truck to the track or anything like that.

 

Thats not bad I guess. I never had any issues out of my stock LSD aside from those clips breaking. I replaced mine because I got such a great deal on new gears, diff and master kit so i replaced it all since I had it all to replace.
