Trac Bar question

[modular93fox]

Looking to help out with wheel hop on the cheap. Since I installed 3.73 and an eaton posi, the truck wheel hops pretty bad on concrert. Cal Tracs are nice, but 400 isnt so nice. A quick search shows something pretty simple and basically the same thing w/o the adjustability and almost no ride quality loss.
What do you guys think? anyone here run something similar? The Ford Ligthing owners speak highly of these types of traction improvers
heres an article:

and some photos from it:

From the threads ive been reading, it completly gets rid of the axle wrap which is the problem im having.
the attached photo is the Rancho trac bar... cant find any links to the product but this is the layout I intend to replicate on my truck... with the bar being either single adjustable or double...
clint

so if the bar is mounted to the bottom of the axle with a rubber busing and attached to the frame the same way would that impare suspension travel.. howver much it moves?
