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 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 CURT 17601 TruTrack 2P Weight Distribution Hitch is designed to enhance the towing experience by providing effective sway control and weight distribution. One of its key strengths is the integrated sway control system, which stabilizes the trailer at two points, ensuring a smoother and safer ride, particularly useful for those who frequently tow heavy loads. With a weight capacity of up to 10,000 lbs, it caters well to larger trailers and provides a significant level of reliability for users needing to manage heavier trailers.

Setup is straightforward due to its easy adjustment features, including a tilting head that allows for changes without full disassembly. This is a great benefit for those who may be less experienced with hitch setups. Additionally, the hitch is made of high-strength carbon steel and finished with a corrosion-resistant powder coat, which enhances its durability against the elements, making it suitable for varied weather conditions.

Weighing in at 94 pounds, this hitch can be cumbersome for some users to handle, especially during installation or removal. The adjustability feature, while beneficial, may still require some familiarity for optimal performance, which could be a challenge for novice users. Finally, despite its solid construction, the hitch's price point may be on the higher side compared to other alternatives in the market, potentially making it less appealing for budget-conscious buyers. The CURT 17601 is a strong option for those seeking a robust weight distribution hitch with effective sway control, particularly for heavier towing needs, although it may require some handling effort and comes at a premium price.
