A notch is required for a 4/6 on a NBS, and you will want assist bags if you have an extra cab and carry passenger or anything in the bed. On an NNBS you can get away with a 4/5 comfortably without a notch. I went from a 4/7 to 4/5 on my NNBS because I didn't want to notch it. Going to put assist bags on it again soon.

My truck is a 2018 Silverado, and in that case would you recommend a 3/5 drop instead of 4/6? I really don’t want to mess with the frame or anything, especially since its 4wd
