1. Andersen Hitches 3350: Best Overall
We found the Andersen Hitches 3350 to be a standout choice due to its innovative no-sway bracket design that works differently than traditional friction bars. By using chains and brackets to hold the trailer tongue firmly, it effectively eliminates sway without the need for adjustment bolts or greased friction pads. Based on owner feedback and the spec sheets, this system is exceptionally quiet and requires very little maintenance compared to standard friction units.
However, this system is not without limitations. It requires a specific Andersen ball mount and is not compatible with other brands of weight distribution hitches. You should skip this product if you already own a heavy-duty round bar or trunnion style hitch head and are looking for a simple add-on sway control unit, as this requires a complete switch to the Andersen hardware ecosystem.
- No-sway bracket design eliminates sway
- Built-in weight distribution system
- Lightweight construction with easy installation
Pros: Silent operation with no metal-on-metal friction; Corrosion resistant materials; Simple hookup and removal process
Cons: Requires specific Andersen ball mount for use
2. Equal-i-zer 90-00-1000: Best 4-Point Control
The Equal-i-zer 90-00-1000 utilizes a proven 4-point sway control system that integrates directly into the weight distribution head. In our evaluation, this design offers superior resistance to trailer sway by applying friction at two distinct points on the trailer frame. The unit is constructed from heavy-duty American steel, which contributes to its high durability rating and consistent performance under heavy loads.
One real limitation noted in our research is the noise factor. The 4-point friction design often produces audible groaning or popping sounds when turning sharply at low speeds, which is normal but can be concerning for new users. We recommend skipping this if you prioritize a silent towing experience or if you have a trailer with unique frame geometry that might interfere with the L-bracket installation.
- Integrated 4-point sway control
- Built-in weight distribution
- Proudly made in the USA
Pros: Proven design with superior sway resistance; Strong steel construction; Works with many trailer couplers
Cons: Can be noisy during sharp turns
3. Blue Ox BXW1000: Premium Choice
The Blue Ox BXW1000 combines weight distribution with sway control using a unique sway control arm design that restricts side-to-side movement. We compared its build quality to competitors and found the powder coat finish to be superior in terms of rust protection. The system is designed to be user-friendly, allowing for easy adjustments to the spring bars to achieve a level ride height without the need for complex tools.
While the performance is excellent, the overall weight of the system is a significant drawback. The heavy steel construction makes the head unit and bars difficult to maneuver during installation, especially for a single person. If you have physical limitations or struggle with lifting heavy equipment, you may want to consider a lighter aluminum or friction-based alternative.
- Sway control with weight distribution
- Easy adjustment with spring bars
- No drilling required for most installations
Pros: Quiet operation compared to friction brands; Built-in sway control arms; High quality powder coat finish
Cons: Heavier than some competitors
4. Reese 26003: Best Friction Bar
We researched the Reese 26003 as a standard friction sway control option that is widely used for smaller travel trailers and utility trailers. It functions by applying pressure to the trailer frame and ball mount, activating only when sway occurs. Our evaluation indicates that this is a reliable, no-frills solution for users who do not need weight distribution but want to improve safety on the highway.
Based on owner feedback, the main weakness of this unit is the maintenance requirement. The friction pads and ball mechanism require regular lubrication to function correctly and prevent seizing. Additionally, this unit does not provide weight distribution, meaning it is unsuitable for heavy tongue weight applications. You should skip this if you need a comprehensive solution that levels your vehicle while controlling sway.
- Fits 2 inch trailer hitches
- Activates on trailer movement only
- Heavy duty steel construction
Pros: Simple installation on most ball mounts; Effective for smaller to mid-sized trailers; Cost effective solution
Cons: Requires periodic lubrication and maintenance
5. CURT 17200: Reliable Standard
The CURT 17200 is a popular friction sway control bar designed to combat fishtailing by creating friction resistance. In our comparison of standard friction bars, this unit offers a robust build quality with a protective powder coat finish. It is a straightforward option for those looking to add an extra layer of safety to their towing setup without investing in a full weight distribution system.
However, we found that the activation handle can be stiff and difficult to maneuver, especially when the unit is under tension. There are also reports from owners about the ball clamp loosening over time if not checked frequently. We suggest skipping this model if you plan on disconnecting and reconnecting the sway bar frequently, as the handle mechanism may prove frustrating.
- Prevents trailer fishtailing
- Durable black powder coat finish
- Easy to engage and disengage
Pros: Brand recognition and availability; Solid construction for the price; Works with Class III and IV hitches
Cons: Handle can be difficult to maneuver
6. Pro Series 83660: Budget Pick
We evaluated the Pro Series 83660 as a budget-friendly option for lighter towing applications. It provides the basic friction sway control necessary for small boats and pop-up campers. The value score is high because it introduces sway safety at a minimal cost, making it accessible for occasional towers who do not need professional grade equipment.
The primary limitation observed in our research is the durability of the finish. The paint tends to chip easily, exposing the metal to rust elements if not touched up promptly. Furthermore, the capacity is lower than premium models. You should skip this product if you tow in harsh winter conditions where road salt is prevalent, as the corrosion resistance is not up to par with higher-end brands.
- Friction control for lighter trailers
- Includes necessary hardware
- Fits standard 2 inch receivers
Pros: Very affordable entry point; Easy to install for beginners; Adequate for small boats and campers
Cons: Paint finish chips easily
7. CURT 17054: Light Duty Option
The CURT 17054 is designed specifically for light duty applications, accommodating tongue weights as low as 200 pounds. We compared this model for owners of small utility trailers or lightweight campers who do not require the heavy build of standard models. It is functional for its intended purpose, offering basic sway reduction for calm driving conditions.
Our evaluation highlights that this unit is significantly less effective in adverse conditions such as high winds or when passed by semi-trucks. The lighter construction and lower friction rating mean it can be overwhelmed quickly. We recommend skipping this product if you plan on highway driving or towing in variable weather, as it lacks the holding power required for unpredictable situations.
- Compact friction sway control
- Designed for lighter loads
- Includes mounting balls
Pros: Good for very small trailers; Compact size for storage; Low cost
Cons: Struggles in high winds or heavy traffic
Frequently Asked Questions
Do I need a sway bar if I have a weight distribution hitch?
Yes, a weight distribution hitch levels the vehicle but does not always eliminate sway. Many modern systems include integrated sway control, but if you have a basic weight distribution hitch, adding a separate sway bar is recommended for safety.
Can I back up with a friction sway bar engaged?
It is generally not recommended to back up with a friction sway bar engaged, especially at sharp angles, as it can damage the bar or the trailer frame. Most manufacturers suggest disengaging the bar before backing up to prevent binding.
How tight should I adjust my sway control bar?
You should adjust the sway control bar according to the manufacturer’s instructions, usually until the handle is difficult to move. Over-tightening can cause excessive wear, while under-tightening will not provide adequate sway resistance.
What is the difference between 2-point and 4-point sway control?
2-point sway control typically uses a single friction bar on one side of the trailer, while 4-point systems use two points of friction on each side. 4-point systems generally offer superior stability and resistance to sway in various driving conditions.
Do sway bars reduce the payload capacity of my vehicle?
Sway bars themselves do not change the payload capacity of your vehicle. However, the weight of the sway control system and the hitch counts against the tongue weight rating of your hitch receiver, which is part of your overall capacity limits.
Our Verdict
Based on our research and comparison, the Andersen Hitches 3350 is the top pick for its innovative no-sway design and ease of use, while the Equal-i-zer 90-00-1000 is the runner up for its robust 4-point control system and heavy-duty construction.
