I have a 2013 scab STX 4x4 with 5.0 v8 & 3.55 with tow package. If I install a Roadmadter Active Suspension will I need to adjust my weight distributing hitch when I tow my TT?

I'm thinking of adding the RAS to help with sway when truck is loaded, but no trailer.

Thanks for any help you can provide.

 

I installed Helliwig anti-sway bar on my '14 scab. No sway and this is with a cap.

 

Yes, you probably need to re-adjust the WDH after any modification to your suspension.
My RAS install lifted the rear about 1" and reduced the amount of sag by more.
This definitely had an effect on the WDH.
