How to Reduce Sway on a 2015 Suburban LTZ with an Auto-Levelling System?

Updated 06/30/2021 | Published 06/29/2021

Question:

Looking to minimize sway when pulling an enclosed car hauler. I use a weight distribution hitch currently but it seems as if minimal tension is required out of the weight bars because the car automatically raises the rear suspension SIGNIFICANTLY to level itself out. My question is 1 which electronic anti sway device will work without interfering with my factory brake controller and 2 is the weight distribution unnecessary when the car is already compensating for rear ride height? Or should I be looking for a way to disengage the auto levelling system and use more tension on the weight distribution bars instead?

This actually happens with vehicles that use an auto-leveling system pretty often. Disengaging this system while towing will definitely help as it will allow your weight distribution system to have more tension on the bars, which will help with sway.

However, if you are unable to turn off the auto-leveling, then you will need to let the vehicle auto-level and then add more spring bar tension to your system. This should get the system to compensate for everything.

With all that being said, if you are still getting a good amount of sway, the Tuson Asymmetric Sway Control System # 335TSC-1000 is completely compatible with brake controllers and should get the extra sway control needed for comfortable towing.
