helper bags with 2-4 drop

[gmclarry]

I want to install helper bags on my 2011 GMC 1500 Sierra. Anyone have experience with them on a 2-4 drop?
What brand is preferred?
If it makes any difference, the rear axle has been flipped.
Thanks!

what drop do you have? Does that company offer a helper bag kit? If they do i would go with it
