I'm gonna disagree with the 99 moog coils. Specifically moog. I had them (80141??) I believe was the part # and within 6 months they were sagging. I have no additional weight on the back either. I went 890s after that.
The photo below shows those same moog coils 6 months in with about 150lbs of gear in the back AND WITH .5 inch spacers on top of them to combat the sagging I was getting. So imagine them another half inch lower.
Other brands might better like ACDelco though
