If you have the auto-level feature, what do these bags do?

Before I lowered the truck I had them because when I would pull a trailer I would inflate them a bit to preload/stiffen up the suspension so as to take some of the weight/strain OFF of the autoride air shocks.

After lowering I keep them inflated to about 10-15lbs to stiffen up the rear suspension. The Belltech 6" springs are too soft in my opinion so the bags help correct that.

The auto leveling still functions as designed. Add folks and luggage to the back and the compressor kicks on to level it all out... unload and you hear the dump valve open and she drops back down.
