Importance of Weight Distribution

A weight distribution hitch is essential for your travel trailer because it ensures proper weight distribution among the axle of your tow vehicle and the axle of your trailer. This even distribution of weight helps to maintain balance and stability while you’re on the road.

The easiest way to appreciate the function of the weight distribution hitch is to understand what happens when pulling a heavy trailer.

First, you’ll have a towing vehicle and trailer to haul the heavy loads. However, the towing car should have a robust suspension system to pull the heavy load.

If the suspension unit is weak, the towing vehicle will bend upward, with the rear end sagging toward the trailer at the back. A weight distribution hitch is what you need to correct the situation.

The primary purposes of the distribution hitch include:

Weight Distribution

The hitch forms a vital bridge between the trailer and the towing vehicle. Once you link the two units, the hitch distributes the tongue weight uniformly to the towing axle and front steering axle and the trailer, resulting in a single unit parallel to the road.

The hitch works like a standard ball mount except that it uses a set of spring bars or chains to accomplish weight distribution.

  • First, the spring bars/chains absorb excessive stress and tension, producing a lifting effect on the rear of the vehicle by placing trailer tongue weight on the front axle of the towing vehicle.
  • Second, the tension created cancels any downward pressure on the vehicle, resulting in a leveled trailer and towing vehicle.

Safety and Stability

When the weight of your travel trailer is properly distributed, it increases the overall safety and stability of your towing setup. This reduces the chances of accidents due to the trailer swaying or losing control while navigating through various road conditions.

Improved Towing Capacity

By using a weight distribution hitch, your towing capacity is significantly improved and for most vehicle manufacturers, you now unlock the maximum towing numbers your vehicle advertises.

With the distributed weight, your tow vehicle can accommodate heavier loads which would otherwise strain and damage the towing system.

Reduced Trailer Sway

Sway control refers to the trailer’s ability to withstand external forces that may push it back and forth when driving. Swaying may occur due to strong winds, uneven weight distribution, speedy driving, road imperfections, sudden application of brakes, or bow waves from other trucks on the road.

Luckily, the spring bars on the weight distribution hitches prevent swaying by keeping the towing vehicle and the trailer in line. As a result, you’ll reduce the chances of toppling, especially when driving at high speeds.

Increased Braking

Uneven weight distribution can lead to poor braking performance and increased stopping distances. By evenly distributing the trailer’s weight across the tow vehicle’s axles, a weight distribution hitch improves braking, helping you stop more efficiently in various road conditions.

Reduced Wear and Tear

Using a weight distribution hitch not only enhances your towing safety and performance but also reduces stress on your tow vehicle and trailer. It minimizes wear and tear on both the tow vehicle’s suspension and the trailer’s frame, prolonging their lifespan and maintaining optimal performance.

In summary, a weight distribution hitch is essential for safely and comfortably towing a heavy trailer. It offers safety benefits, improved vehicle control, leveling of the tow vehicle and trailer, increased braking, and reduced wear and tear. Investing in a quality weight distribution hitch will enhance your towing experience and help protect your tow vehicle and trailer.

Fuel Economy

Proper weight distribution also has a positive impact on your fuel economy. The even distribution of weight allows your tow vehicle to maintain consistent speeds and reduces the need for constant acceleration, which in turn results in better fuel consumption.

Reduced Structural Damage

Without a weight distribution hitch, the excessive weight on your RV hitch may result in damage to both your tow vehicle and your trailer. By evenly distributing the weight, structural damage is minimized, and you protect your investment in both your vehicle and your trailer.

Components of a Travel Trailer Weight Distribution Hitch

When setting up your travel trailer, it’s essential to have a weight distribution hitch to ensure safe and comfortable towing. In this section, we’ll discuss the primary components of a weight distribution hitch and their functions.

Head Assembly

The head assembly is the main component that connects your travel trailer to the tow vehicle. It’s crucial to choose a head assembly that fits your RV’s hitch weight and is compatible with the manufacturer’s specifications. The hitch head is designed to hold the spring bars and sway control devices securely. Selecting the right head assembly ensures proper weight distribution and helps prevent sway.

Spring Bars

Spring bars are essential components of a weight distribution hitch. Their primary function is to redistribute the hitch weight from the back of the tow vehicle to the front wheels and the axles of the travel trailer. Spring bars come in two main types: round bar and trunnion bar. While both types serve the same purpose, trunnion bars are usually more robust and better suited for heavier RVs. Make sure to choose spring bars that match your RV’s weight rating.

There are two main types of spring bars and one type with chains:

  • Round bars: These are the most common type and are attached to the head assembly using chains and clips. They offer good weight distribution at a lower cost but may have less ground clearance.
  • Trunnion bars: These bars slide directly into the head assembly and offer better ground clearance and a more rigid connection, although usually at a higher price.
  • Chains: Chains can also be used to redistribute the weight on weight distribution hitches. The Andersen is the only hitch that uses chains. The benefits are more customizable weight distribution, lighter unit overall, and quieter (no annoying noises when turning). We have this Andersen hitch and LOVE it.


The shank is a critical component that connects the head assembly to the tow vehicle’s hitch receiver. Ensuring a proper fit requires selecting a shank with the appropriate size and rise/drop for your tow vehicle. It’s crucial to note that not every shank can fit every hitch head, so always refer to the manufacturer’s guidelines when choosing your shank.

Frame Brackets

Frame brackets are mounted on the travel trailer’s frame and provide a connection point for the spring bars. These brackets vary in design depending on the spring bar type (round or trunnion), but they ensure a secure connection and proper weight distribution. Make sure to follow your manufacturer’s recommendations for installing and adjusting frame brackets on your trailer frame.

Sway Control Devices

While not a mandatory part of a weight distribution hitch, sway control devices are recommended for better towing performance, especially for larger or longer trailers. Sway control devices help to limit side-to-side movement and sway, improving both the tow vehicle and travel trailer’s stability. There are two primary types of sway control devices: friction sway control and dual-cam sway control. Choose the sway control device that suits your towing needs and ensures proper compatibility with your weight distribution hitch.

By carefully selecting and setting up each component of your weight distribution hitch, you’ll ensure a safe and enjoyable towing experience for your travel trailer.

Types of Weight Distribution Hitches
