How to Stop Trailer Sway: Proven Solutions for Safer, More Confident Towing
2/12/2026
Trailer sway is one of the most common – and dangerous – problems drivers experience when towing. If you’ve ever felt your trailer begin to fishtail or push your vehicle side to side, you know how quickly sway can turn a normal drive into a white-knuckle situation.
The good news? Trailer sway is preventable. Understanding why it happens, and choosing the right suspension solution, is the key to towing safely and confidently.
What Causes Trailer Sway?
Trailer sway typically occurs when the balance between the tow vehicle and trailer is compromised. Common causes include:
When the rear of the vehicle sags, steering geometry changes, braking performance suffers, and the trailer gains leverage, creating the perfect conditions for sway.
How to Stop Trailer Sway (The Right Way)
Stopping trailer sway isn’t about one quick fix, it’s about restoring stability and control to the entire towing setup. Here are the most effective solutions.
1. Eliminate Rear-End Squat
Rear-end squat is one of the biggest contributors to trailer sway. When the back of the vehicle compresses under load, it reduces front axle traction and steering control.
The fix: One of the most effective ways to stop trailer sway is to eliminate rear-end squat using air spring load support systems which help restore proper ride height and improve towing stability.
