Of all these posts/threads it would be instructive to see scale weights: that the Steer Axle is being loaded by the WDH properly when the truck is equipped with this device.
I have not found any recommendation of ever increasing the Drive Axle/Ball Center distance to be a good thing; quite the reverse. No one recommends buying a TV with a long rear overhang.
So if this compromise is a good one, where are the scale ticket numbers with and without this device attached? Hopefully it has no effect, but . . . ?
The company video shows cranking the WD bars THEN adjusting the air bag pressure to cause the rods to be parallel; backwards, also, from advice here and elsewhere about dealing with air ride rear suspensions.
The MorRyde rear spring shackle replacement is the same in price or cheaper, and doesn't adversely affect hitch rigging geometry; I can hardly see wanting a compromised alternative (however much I want a softer ride).
