10 Best Trailer Sway Bars 2025 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 Reese Integrated Sway Control Weight Distribution Kit is a strong contender for those seeking to enhance their towing experience with a focus on stability and safety. With a weight capacity of 11,500 lbs, it can accommodate a variety of trailers, making it a versatile choice for truck and trailer owners. One of its standout features is the preinstalled sway control ball, which simplifies the setup process, allowing for an easy installation with all necessary hardware included. The tapered spring bars are designed to maintain constant weight distribution, contributing to improved ride comfort.

Durability is another highlight; constructed from high-strength steel with a powder coat finish, it effectively resists corrosion and wear, promising longevity. The deep drop shank adapts to taller trucks, providing added flexibility in fitting different vehicle types. The no-drill, clamp-on brackets are also convenient, fitting various trailer frames without hassle.

It is important to note that the kit is relatively heavy at about 102.7 pounds, which could be cumbersome for some users during installation or transport. This kit is ideal for those who prioritize stability and ease of installation in their towing setup, but it may require a bit of effort during installation for those unfamiliar with such systems.

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.
