It helps distribute the weight evenly across the axles, maintaining proper balance and reducing the risk of swaying or fishtailing. Improved stability contributes to better handling and control, particularly during turns, lane changes, or encounters with crosswinds.
• Steering Response: The suspension system influences the steering response of the towing system. It affects factors such as wheel alignment, tracking, and roll resistance. A well-designed suspension geometry ensures that the wheels track properly, minimizing sideways movement and improving steering precision. This enhances the overall handling and maneuverability of the towing system.
• Trailer Sway Control: The suspension design can incorporate features to mitigate trailer sway. Sway control mechanisms, such as sway bars or electronic stability control systems, can be integrated into the suspension system to improve handling and reduce the risk of trailer sway. These features contribute to safer and more controlled towing.

In summary, trailer suspensions significantly affect the ride quality and handling of a towing system. They impact factors such as shock absorption, bouncing and pitching, vertical movement, stability, steering response, and trailer sway control. A well-designed suspension system provides better ride comfort, reduces driver and passenger discomfort, enhances stability, improves handling characteristics, and contributes to a safer and more enjoyable towing experience.
