I can fit the 37s and 24s with a 4-6 cognito?
You Gotta compare apples to apples. If your looking at a BDS 6.5" and a Rough Country 7.5", then you gotta at least look at cognito's 7" kit. This is my first Duramax and my first Lift but I did a lot of research and nobody seems to complain about cognito's ride or quality or install. The only rough edge on a cognito is price, as they seem to be high, if not the highest. But as in most things, you get what you pay for.
