Is Sway Control Needed for 2026 Silverado 3500 Dually Towing 35' Brinkley Z Air 297  

Updated 04/16/2026 | Published 04/01/2026

Question:

I am trying to determine if I will need sway control for 35foot travel trailer to go along with this hitch? I have a 2026 Chevy 3500 DRW truck.

Hello again Michael; you don’t have to run sway control with that setup, but I would recommend it. A 35' trailer like your Brinkley 297 is a long lever arm behind the axles and has a tall, flat side profile. This makes it more susceptible to being pushed around by crosswinds and passing trucks. Sway control will definitely help with overall stability.

The Shocker Sway Control Friction Arm Bar Kit For Trailers Over 10,000 lbs # SHK27YR will work with this setup. You will also need the Gen-Y Dual Sway Control Bracket #325-GH-300-1 to attach it to the # 325-GH-1125. I recommend running the dual sway control bars for best results.

Have you had a chance to tow the Brinkley yet?

Does Gen Y not make a sway control kit to go along with this setup?

@MichaelD they do have the GH-601 but we no longer carry it.

@RobinH Can you confirm Gen-Y Dual Sway Control Bracket #325-GH-300-1 is the correct option for this setup? It shows compatible with 2" Shank but mine is 2 1/2" so that has me confused. The next size up 600-1 seems to be for 21K plus?

@Michael the main shank is 2-1/2" but the stacked receivers are 2". The ball platform # 325-GH-300-1 fits around is technically 1.980" to fit in the 2" receivers.
