You seem to be a little confused. It takes less PSI to lift the rear of a truck with the bags on the bars due to the leverage of the mechanical advantage. One could end up with a "better ride" due to lower spring that is a result of the bags being at a lower psi. One could also put to big of bags to far forward on the bar and ending up with to soft of a set up getting lift at to low of PSI. The second scenario would be multiplied by the absence of shocks.
I hope this helps, and if anyone has anything to add, please do so!
