I looked for months and could not find any info on stock (no leveling kit) nbs silverado 1500's running a 275 60 20 tire on any forums, the only thing I found was people with that size tire and a leveling kit which was no good to me so I bit the bullet and bought them and they fit just fine. I hope I answered a question some of you might of had and if not sorry for wasting your time.

 

A late thank you for info I just bought a set based on your info.
