Thanks for the time you spent writing this up. Great information.A steering brace is not going to make big dips and bumps go away, they are going to effect your steering no matter what.
The steering brace stabilizes the steering box sector shaft that the pitman arm bolts onto. What the brace does is eliminate minor wondering from the steering linkage putting pressure on the steering sector shaft causing it to move which wears out the seal and bearing prematurely.
By installing the steering stabilizer brace you are stabilizing the steering box sector shaft keeping it from moving side to side or front to rear which is what wears out the seal and bearing.
If you are hitting a dip or bump big enough it can still push on the steering linkage causing the steering to move but with a steering stabilizer brace the sector shaft will not move side to side or front to rear so it won't be contributing to the issue of the rest of the steering linkage moving during the time it is dealing with the forces of the large dip or bump.
While FCA/Ram has improved the front end steering components over the years they have not cured the age old problem of the steering linkage causing undue wear on the steering box sector shaft so from me I will advise you to pick up one of Dodge Off Road steering braces and install it as it will protect the steering sector shaft from excess wear and tear.
