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 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 Equal-i-zer 4-point Sway Control Hitch is a strong choice if you tow medium to heavy trailers up to 12,000 lbs. Its unique 4-point sway control system offers one of the best protections against trailer sway, making your driving safer and more stable. This hitch also distributes the trailer's tongue weight evenly across all axles, which helps your tow vehicle maintain steady steering and braking, reducing stress while on the road.

It's built from durable alloy steel with a painted finish, giving it good resistance to wear and weather. The hitch fits most bumper-pull trailers, including RVs, horse trailers, and boats, adding to its versatility. Installation is straightforward but might require some effort to get the sway control bracket positioned correctly (27"-32" back from the coupler center). It offers some adjustability with its spring bars and shank length (12"), accommodating different trailer heights and rises/drops. One thing to keep in mind is that the ball is not included, so you'll need to purchase that separately. At just under 9 pounds, it's reasonably lightweight for a hitch of this capacity.

Many users rate it highly for performance and durability, though it may be overkill for smaller trailers or casual towing. For those seeking solid, integrated sway control combined with weight distribution in one hitch and towing trailers near the upper limits, the Equal-i-zer is a reliable option that can improve towing safety and comfort.
