10 Best Trailer Sway Bars 2025 in the United States

The Equal-i-zer 4-point Sway Control Hitch stands out for its impressive sway control, making it a solid choice for anyone looking to enhance the stability of their trailer while towing. With a weight capacity of up to 10,000 lbs for the trailer and 1,000 lbs for tongue weight, it accommodates a wide range of trailers, including RVs, boats, and utility trailers. The integrated 4-point sway control technology is among the best available, effectively minimizing sway and improving towing safety, which is crucial for family trips or transporting valuable loads.

Installation is relatively straightforward, but may require some mechanical knowledge or experience, especially for those unfamiliar with trailer hitches. The adjustability options, including various shank lengths and the ability to work with different trailer heights, provide flexibility and cater to different towing setups. That said, the hitch's weight (102 pounds) may make it cumbersome for some users to handle during installation or adjustments.

Durability is commendable, with a powder-coated finish and alloy steel construction, ensuring it can withstand harsh conditions and heavy use. However, the hitch does not come with a ball, which is an additional purchase that potential buyers need to consider. Furthermore, while the Equal-i-zer is designed for a range of trailers, it may not fit every specific model perfectly, depending on unique configurations or aftermarket modifications.

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.

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.
