"Rock crawler" type action yea ok but most guys don't use leaf springs once get into it to that point anyway, if did use leaf springs track bar wouldn't be the only thing limiting travel.

but both of your trucks have the shackle in front of the springs, correct??
with a reverse shackle kit, the shackle is in the back of the spring and mounted to the outside of the frame, not inside the frame like the front mount shackle is. this eliminates the need for a track bar.

There is a REASON the RSK manufactures give you a track bar drop bracket. They would not take the time and effort to make and give you one, if you didnt need it

what causes the movement isnt front or rear shackles its the narrow shackle mount factory in front that makes it so much worse in stock setup the rear shackle makes a better ride and a more solid mount on these trucks
now any leaf spring will wobble if there is any movement possible in the rubber bushing in the spring and the more arch the spring has the worse it will be
personally for a mostly street truck i would run the track bar

like i said, the ONLY trucks i have ever had any problem with were front shackle trucks.
my old dodge just before i junked it had 1/4 turn play in the front end because everything was worn out, and it had no problems with death wobble.

The 99-04 SD have a track bar from the factory. You saying Ford waisted $75 a truck putting it on? I dont think so

If avoid the zero / negative side of caster setting then problem isn't or shouldn't be as big an issue, maintaining positive caster reduces need for trackbar but does not not necessarily eliminate it.
Amount of lift, tire size/tire weight/tire width/rim backspacing etc have some effects that proper caster setting alone can't overcome. Maintaining enough positive caster or positive caster to start with isn't always possible for the average joe working in a shade tree type shop IE; knuckle/pig rotation. A trackbar is fairly easy to retain and or add in that type setting/setup.

Because you don't steer with the rear axle, if It slides left or right 2" it still points forward...if the front axle slides left 1" the wheels now point right because the tierods and pitman arm don't move with the axle. Thus the death wobble starts.... I would think new parts would only make this problem worse, worn tierod ends and steering boxs would take up some of the left/right movement and reduce the death wobble.

i just went out and looked and you are correct, the superdutys do have them. funny, i never noticed them before, but then again i was not looking for them.
my 88 does not have a track bar on it because it has a reverse shackle kit.
when it had the death wobble, i got into the front end and found the kingpins were shot.
after i replaced the kingpins the wobble went away.
