10 Best Trailer Sway Bars 2025 in the United States

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 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.

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.
