IMO it calms the rear end down a fair bit. It doesn't do much for the vertical motion (bumps) - that's not what sway bars are for - but it helps control horizontal motions and is more stable through corners. At least that's what I experienced with the FX4 suspension.

I don't like "bouncy rears".......just sayin'

Not quite my experience.

First of all, there is no relevance whatsoever with thr FX4 suspension as it too doesn't have a rear swaybar.

I used the intermediate and mild settings on the hellwig and found little to no improvement over stock with regards to the bouncey, bunny hop happy, rear end. Sure it helps a little around sweeping curves such as on ramps, but hit any off centered bump in that curve or in any other situation, and the truck will bunny hop it's ***.

Let's not falsely guide people into buying a product to solve an issue that it does not.

It's not worth my time to remove the hellwig from my truck to recoup any investment, and doesn't worsen anything. That's the only reason it is still on.
