It is a function of limited travel in the individual wheels... to change that would be a major undertaking.
I see some Trax owners want kits to Lower the suspension, I see none to Raise it... but that is another possible way to make bad things worse, depending on how it is done.
The Trax is actually Independent Suspension. The image posted above shows part of the story, but not all. That big U shaped thing is actually 3 separate pieces, the ends pivot on the cross beam.
Independent Suspension does not have much to do with it anyway. As an example the most capable Off-Road vehicle, the Unimog, has rigid axles but Lots of travel (and a flexible frame too).
On looking under mine (2016 Trax LTZ) I see there are no sway-bars either front or back. No help there. Sway-bars are intended to keep the two sides in sync, off roaders disconnect them, or remove them entirely.
