Stock airbags for 2016 sr5?

Hi, I have a 2016 2wd sr5 with towing package, and my truck has airbags in the rear. Looking up my vin it didnt say anything about airbags as an option so wondering if these may have been aftermarket? I'm second owner. Also, cant find any writing on the bags or tank. Thanks

 

That's an Airlift aftermarket system on your truck. Where did you get your truck, I traded in one with Airbags,

 

Airlift is the brand? I dont reallyneed it and may take it off and try and sell. Thanks

 

Well it came from Canada, forget where, maybe Ontario, but bought it at carvana in cleveland.

 

I traded in my '16 a few weeks ago with airlift. Super white.

 

I got this beginning of October, but its also super white with airlift. Thats funny
