It s 5 link. On something with a single radius arm like an fj80 or 2016 G wagon, yes lift will do that, but with a 5 link, they can increase, decrease, or make it completely neutral, or whatever they want when the axle articulates. My guess is, it's close to neutral throughout the range. If return to center continues to be an issue, my guess is someone will come out with some offset bushings to add some caster.

Or longer lower control arms. Either way.

The returning force comes somewhat from toe in/out and mainly from the caster.

Changing the height of the car via a suspension lift reduces the force as it reduces the caster.

Wouldn't there be a slight increase in negative caster if you lift just the front of the vehicle? I'd think vehicles fitted with front lift springs or leveling pucks should exhibit some (very) slight steering improvement.

EDIT: Correction several posts below.

Wenn the upper and lower links are parallel, then yes. If not, the caster angle changes. And their length plays also a role, so that the caster doesn't change must not be the case...it depends. However, I didn't had a look at how the setup is in the Grenadier, yet.

Sorry everyone. Brain fart. I just realized I should have said "an increase positive caster if you lift just the front of the vehicle".
