Death wobble is caused by worn out tie rod ends and ball joints. The steering links have nothing to do with it. The only way to stop DW is to use a drag link with heim joints at the knuckles instead of tierod ends.
Death wobble is basically upsetting the gyroscopic force that the wheels create when they spin. (Hence why slowing down is the only way to stop it). What happens is you upset one force and it's tied to the other side with the drag link which upsets the other side, unfortunately the new forces don't match. The end up 90-180* off because the tierod end allows the knuckles just enough slack to wobble independently. Then it goes back and forth until starts moving enough to throw the steering wheel around.( of course this all feels instantaneous cus it happens so quick). That's why no steering damper, steering brace etc on the market will stop it, no matter how they advertise it.
On top of that, if you run aftermarket wheels with less offset/backspace you've lengthened the lever on the knuckle making it that much easier for one side to get upset.
(This is all assuming the rest of your suspension is in good shape too, if the trac bar is worn, shocks, those are also potential reasons the front end can get upset)
This was a huge problem on 2nd gen Rams. My '00 and '01 cummins would do it from time to time, usually pulling a trailer because now you've lightened the load on the font tires and the scrub radius effect can't help keep the fire pointed straight as much.
So again, the only true fix is to use a drag link with heim joints so that the knuckles cannot have any slack side to side and start fighting each other.
Look up a DW on a motorcycle, it's the same thing, just one tire, and it's because you've upset the gyroscopic force of the wheel.
