swaybar thicker on Limited than SR5/Trail(non-KDSS)?

[4RBob]

I noticed different part numbers (harper's part's list) for Limited's front swaybar and swaybar bushings. I wonder if it is any thicker? Maybe it isn't just the XREAS shocks that make it more stable?

Seems odd for it to be different, but at the same time I wouldn't put it past Toyota to do that.

I also noticed different springs....just wondering if different (heavier) spring rates as well?

I think the Limiteds have thinner sway bars due to XREAS adding some stability. A thick sway bar is not desirable, I assume it would make the ride too stiff.
