Frequently Asked Questions

How do weight distribution bars work?

Weight distribution bars, or spring bars, work by leveraging the tongue weight of the trailer. They are connected from the trailer A-frame to the hitch head on the tow vehicle. When tensioned, these bars create upward force on the hitch, which then transfers a portion of the tongue weight forward to the tow vehicle’s front axle and backward to the trailer’s axles. This re-levels the tow vehicle, restores steering and braking control, and reduces stress on the rear suspension.

Do I need weight distribution bars for my trailer?

Whether you need weight distribution bars depends on your trailer’s tongue weight and your tow vehicle’s specifications. Most tow vehicle manufacturers recommend a weight distribution hitch for tongue weights exceeding 500 pounds, or if the Gross Trailer Weight (GTW) exceeds 5,000 pounds. Even below these thresholds, if you notice significant rear sag in your tow vehicle, poor steering response, or trailer sway, a weight distribution system can greatly improve safety and handling.

What is the difference between weight distribution and sway control?

Weight distribution primarily focuses on leveling the tow vehicle and trailer by redistributing tongue weight across all axles, improving steering, braking, and tire wear. Sway control, on the other hand, is designed to dampen the side-to-side movement of the trailer, often caused by wind, passing vehicles, or uneven roads. Many modern weight distribution hitches integrate sway control features for a comprehensive solution, but they address different aspects of towing stability.

Can I back up with a weight distribution hitch?

Most modern weight distribution hitches with integrated sway control can be backed up without issue. However, some older designs or those with separate, add-on friction sway control bars may require the sway control mechanism to be disengaged before backing up, particularly on tight turns, to prevent damage. Always consult your specific hitch’s owner’s manual for guidance on backing up.

How do I determine the correct tongue weight capacity for my hitch?

To determine the correct tongue weight capacity, you first need to know your trailer’s actual tongue weight when loaded for travel. This can be measured with a tongue weight scale or by using a public scale. Once you have this number, choose a weight distribution hitch with a capacity range that comfortably accommodates your trailer’s tongue weight. It’s crucial not to exceed the hitch’s maximum capacity, nor to use a hitch with a capacity that is excessively high for your tongue weight, as this can lead to a stiff ride and reduced effectiveness.
