Travel trailer sway can transform a pleasant road trip into a terrifying ordeal. Installing anti-sway bars significantly enhances towing stability and safety, providing greater control in challenging conditions.
Understanding the Importance of Anti-Sway Bars
Towing a travel trailer adds complexity to driving. The trailer’s weight and aerodynamics can create instability, leading to sway caused by wind gusts, uneven road surfaces, or sudden maneuvers. Sway occurs when the trailer oscillates from side to side, potentially escalating into a dangerous loss of control. Anti-sway bars (also known as sway control bars) are designed to counteract these forces, providing resistance to lateral movement and keeping the trailer aligned with the tow vehicle. They work by connecting the trailer’s frame to the tow vehicle’s receiver hitch, creating a system that reduces the trailer’s ability to independently pivot. This is essential for a safe and enjoyable towing experience, particularly when towing larger or heavier trailers.
Types of Anti-Sway Bars
Before diving into the installation process, it’s important to understand the different types of anti-sway bars available:
-
Friction Sway Control: This is the most common and affordable type. It uses a telescoping arm with friction pads to resist swaying motion. The friction is adjustable, allowing you to fine-tune the amount of sway control.
-
Dual Cam Sway Control: This system utilizes cams and springs to provide a more progressive and responsive level of sway control. It offers greater stability, especially in high-wind or emergency situations. This type is often integrated into weight distribution hitches.
-
Electronic Sway Control: These systems use sensors and actuators to automatically adjust braking forces on the trailer wheels, correcting sway in real-time. While the most advanced option, they’re also the most expensive.
This guide will primarily focus on the installation of friction sway control, as it is the most widely used and generally suitable for a variety of travel trailers.

-
Prepare the Tow Vehicle:
- Ensure the tow vehicle is parked on a level surface and the parking brake is engaged.
- If necessary, use a jack and jack stands to raise the rear of the vehicle for better access to the hitch receiver.
- Attach the ball mount to the receiver hitch.
-
Install the Ball Mount Plate:
- The ball mount plate (also called a sway control ball mount) provides the attachment point for the sway bar on the tow vehicle.
- Position the ball mount plate on the ball mount, aligning the pre-drilled holes.
- Secure the plate to the ball mount using the provided bolts and nuts. Torque these bolts to the manufacturer’s specifications.
- Apply lubricant to the ball on the ball mount for smooth operation.
-
Attach the Frame Brackets to the Trailer:
- The frame brackets attach to the trailer’s A-frame and provide the connection point for the sway bar on the trailer side.
- Carefully measure the distance from the trailer coupler to the specified mounting point on the A-frame (refer to the instructions).
- Mark the mounting locations using a marker or pencil.
- Important: Check for any obstructions, such as wiring or plumbing, before drilling.
- Drill pilot holes at the marked locations, using the appropriate drill bit size.
- Attach the frame brackets to the A-frame using the provided bolts, nuts, and washers. Torque these bolts to the manufacturer’s specifications.
-
Connect the Anti-Sway Bar:
- Connect one end of the anti-sway bar to the ball mount plate on the tow vehicle.
- Connect the other end of the sway bar to the frame bracket on the trailer.
- Ensure the sway bar is properly aligned and securely fastened at both ends.
- The sway bar arm should be roughly parallel to the ground when the trailer is connected.
-
Adjust the Tension (if applicable):
- Friction sway control bars typically have an adjustable tension knob.
- Start with a low tension setting and gradually increase it until you achieve the desired level of sway control.
- Over-tightening the tension can hinder turning and cause undue stress on the system.
- Experiment with different tension settings on a short, controlled test drive to find the optimal setting for your trailer and towing conditions.
-
Final Inspection:
- Double-check all connections to ensure they are secure and properly torqued.
- Verify that the sway bar arm has adequate clearance and does not interfere with any other components.
- Review the manufacturer’s instructions for any additional recommendations or maintenance procedures.
-
Post-Installation Test Drive:
- Take a short test drive on a quiet road to evaluate the effectiveness of the anti-sway bar.
- Gradually increase your speed and observe how the trailer responds to steering inputs and wind gusts.
- Adjust the tension on the sway bar as needed to achieve optimal sway control.
Troubleshooting Common Issues
- Squeaking or Groaning: This is often caused by dry friction surfaces. Apply a small amount of lubricant to the ball joints and friction pads.
- Binding During Turns: Reduce the tension on the sway bar. If the problem persists, ensure the sway bar is properly aligned and the frame brackets are correctly positioned.
- Excessive Sway: Increase the tension on the sway bar. If the problem continues, consider upgrading to a dual cam or electronic sway control system.
