I just ordered front and rear Hellwig sway bars from amazon. 7180 rear / 7718 front. The rear air bags mainly act as helper springs for weight - they do very little for sway from wind / trucks / uneven roads / etc. My Bilstein shocks and damper helped a lot...I hope these sway bars compliment the shocks.
