The CURT 17063 Round Bar Weight Distribution Hitch is designed to improve towing stability and control. It does this by distributing the tongue weight of the trailer across the vehicle-trailer combination, which helps level the load and reduce trailer sway. One of its key features is the integrated lubrication system that ensures smooth and quiet towing, supported by two grease zerk fittings for easy maintenance.

This hitch is built from durable forged steel, giving it a strong and reliable structure capable of towing between 10,000 to 14,000 lbs and handling a tongue weight of 1,000 to 1,400 lbs. These capacities make it suitable for heavy-duty towing needs.

On the downside, the hitch weighs 100 pounds, which could make installation and handling more challenging for some users.

Buying Guide for the Best Trailer Sway Bars

When it comes to towing a trailer, safety and stability are paramount. Trailer sway bars, also known as weight distribution hitches or anti-sway bars, are essential components that help to maintain control and reduce the risk of swaying while driving. Choosing the right sway bar for your trailer can make a significant difference in your towing experience. Here are some key specifications to consider when selecting a trailer sway bar.
Weight CapacityWeight capacity refers to the maximum weight that the sway bar can handle. This is crucial because using a sway bar with an insufficient weight capacity can lead to ineffective sway control and potential safety hazards. Weight capacities are typically divided into segments such as light-duty (up to 5,000 lbs), medium-duty (5,000-10,000 lbs), and heavy-duty (over 10,000 lbs). To pick the right one, you need to know the total weight of your trailer and its contents. Always choose a sway bar that matches or exceeds your trailer's weight to ensure optimal performance.
Type of Sway ControlThere are different types of sway control mechanisms, including friction sway control and dual-cam sway control. Friction sway control uses friction to resist trailer movement, making it suitable for smaller trailers. Dual-cam sway control, on the other hand, uses a cam system to provide more precise control and is better for larger trailers. To choose the right type, consider the size and weight of your trailer. For smaller trailers, friction sway control is usually sufficient, while larger trailers benefit from the enhanced stability of dual-cam systems.
Ease of InstallationEase of installation refers to how simple it is to set up the sway bar on your trailer. This is important because a complicated installation process can be time-consuming and frustrating. Sway bars can range from easy, DIY-friendly installations to more complex setups that may require professional assistance. If you prefer to handle the installation yourself, look for sway bars that come with clear instructions and all necessary hardware. If you're not comfortable with DIY projects, consider opting for a model that can be professionally installed.
AdjustabilityAdjustability refers to the ability to fine-tune the sway bar to match your specific towing conditions. This is important because different driving conditions and trailer loads may require different levels of sway control. Adjustable sway bars allow you to customize the tension and control settings, providing a more tailored towing experience. If you frequently tow different loads or drive in varying conditions, an adjustable sway bar can offer the flexibility you need. For consistent towing conditions, a fixed sway bar may be sufficient.
Durability and Build QualityDurability and build quality refer to the materials and construction of the sway bar. This is important because a well-built sway bar will last longer and perform better under stress. Sway bars are typically made from steel or other high-strength materials to withstand the rigors of towing. When choosing a sway bar, look for one with a solid construction and good reviews regarding its longevity and performance. A durable sway bar will provide reliable sway control and reduce the need for frequent replacements.
