10 Best Trailer Sway Bars 2026 in the United States

The CURT 17500 TruTrack 4P is a solid choice for those needing a weight distribution hitch that also actively controls trailer sway. With a strong towing capacity of up to 10,000 pounds, it’s suitable for medium to large trailers, making it a good fit for many towing needs. It uses a spring and cam system with fixed brackets to control sway at four points, which means it works actively to keep your trailer steady rather than just resisting sway passively.

Installation and adjustment are user-friendly thanks to its tilting head and hex castle nuts, so you can fine-tune it without taking the hitch apart. The adjustable shank adds flexibility for a better fit with your vehicle setup. Durability is another strong point—the hitch is built from carbon steel with a welded head and cast parts, finished in a tough powder coat that resists rust and harsh weather. Weighing just 12 pounds, it’s not overly heavy for handling.

While the setup is designed to be straightforward, some first-time users might find the precise adjustments a bit tricky until they get the hang of it. Also, it fits a 2-inch receiver with a 2-5/16-inch ball, so ensure your towing rig matches these specs. For those seeking a dependable hitch that provides both solid weight distribution and active sway control with good durability, the CURT 17500 TruTrack 4P presents a compelling option.

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. The hitch is also highly adjustable, thanks to its 2-inch shank that fits most standard 2-inch trailer hitch receivers, and it comes with a pre-torqued 2-5/16-inch trailer ball for added convenience.

On the downside, the hitch weighs 100 pounds, which could make installation and handling more challenging for some users. Additionally, while the corrosion-resistant powder-coated finish enhances durability, the material is primarily aluminum, which might not be as robust as some steel counterparts. This hitch is best suited for those needing a strong and reliable solution for heavy-duty towing with integrated sway control and lubrication features.

The Equal-i-zer 4-point Sway Control Hitch is a solid choice for trailer owners looking to improve safety and control while towing. It handles up to 16,000 lbs of trailer weight and 1,600 lbs of tongue weight, which means it fits medium to heavy trailers well. This hitch combines sway control with weight distribution, helping to reduce trailer sway, improve steering, and make braking smoother — all of which can make towing less stressful.

Made from strong alloy steel with a painted finish, it's built to last and withstand regular use on the road. The kit is designed to fit a wide range of trailers with 4 to 8-inch frame heights, which covers many typical bumper-pull trailers. The hitch is praised for its robust build and effective sway control system, although it does not include the hitch ball, so you’ll need to get that separately.

Installation is generally straightforward but may require some time to adjust and set up correctly for your specific trailer and vehicle. The hitch also offers some adjustability in terms of shank length and frame height compatibility, adding to its flexibility. For those seeking a reliable, universal-fit sway control hitch that balances durability and performance, the Equal-i-zer is a strong option, especially for regularly towing heavier trailers.
