when my 250 was stock height, i had them on and it made a considerable difference both with the trailer (1150 tongue weight) and the gooseneck i hauled only a few times....
1. they let me level the truck so my HID's dont singe oncoming drivers retinas
2. they really take away the "swimmy" feeling the trailer sometimes had over wavy roads
3. they seemed to make the truck ride a little better even when unloaded and set to about 5psi...
the only negative i ever had was that they can affect the adjustment of a wdh if your using them in that type of situation.....the bar tension is a function of the head pitch/tilt setting....and raising the truck takes load off the bars
now that i lifted my truck, it has new blocks in the back that intefere with the bag....so im gonna have to modify them a lil (the ears on the blocks that is)
