The Long awaited sway-bars for the revo are on their way to my house. I've had them back-ordered from Tower hobbies since the 1st, and they shipped yesterday

I could have got the Tekno ones, but I would have pipe-clearance issues because they mount on TOP of the rocker in the rear, VS bottom on the Traxxas one. I'm not sure if Traxxas will release diff sway-bar thicknesses but since there is so much room to play with I bet you could stiffen them up a ton just by moving the collars down a bit.

Will report in for revo guys who do not yet have any swaybars.
