10 Best Trailer Sway Bars 2026 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 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.
