They are exactly the same as normal swaybars... The only 'upgrade' there is that they can handle more suspension travel and can be tuned more easily.
This is an issue on solid axles - the springs are mounted inboard from the wheels, so the roll rate of the suspension is lower than the wheel rate - which leads to excessive body lean (or articulation, depending on what exactly is happening at the time). Maximum use of travel with the least body roll happens when you add back the right amount of roll stiffness to match the wheel rate.
On a 3rd gen 4runner, this can be achieved by removing the front swaybar and keeping the rear (factory) swaybar - unless you have changed the rear geometry. (the front IFS has a matched wheel rate and roll rate when there is no swaybar)
This is from a 4th/5th/FJ, but still generally applies to a 3rd gen:
