Understanding Weight Distribution Hitches

A weight distribution hitch is designed to evenly distribute the weight of a trailer across the axles of the tow vehicle and the trailer itself. This helps to level the vehicle and trailer, improving handling, braking, and overall stability. Without a weight distribution hitch, excessive weight on the rear of the tow vehicle can cause the front end to lift, reducing steering control and braking effectiveness.

Why Use a Weight Distribution Hitch?

• Improved Handling: By distributing weight evenly, the tow vehicle maintains better contact with the road, enhancing steering and stability.
• Enhanced Braking: Leveling the vehicle ensures that all brakes work effectively, reducing stopping distances.
• Reduced Sway: Weight distribution hitches minimize trailer sway, making towing safer and more comfortable.
• Prevention of Sagging: They prevent the rear of the tow vehicle from sagging under the weight of the trailer, which can damage the suspension and frame.

Components of a Weight Distribution Hitch

A typical weight distribution hitch includes several key components:

• Hitch Head: This is the main part that connects to the tow vehicle's receiver. It includes the ball mount and the pivot points for the spring bars.
• Spring Bars: These bars connect to the hitch head and extend back to the trailer frame. They provide the tension needed to distribute weight.
• Trailer Brackets: These brackets attach to the trailer frame and provide the connection points for the spring bars.
• Lift Chains or Brackets: These components are used to adjust the tension on the spring bars.

Step-by-Step Guide to Adjusting Your Weight Distribution Hitch

Step 3: Measure Initial Ride Height

Measure the ride height of your tow vehicle and trailer before attaching the weight distribution hitch. This will serve as your baseline for adjustments.

1. Measure the Front Fender Height: Measure the distance from the ground to the top of the front wheel well on both sides of the tow vehicle. Record these measurements.
2. Measure the Rear Fender Height: Measure the distance from the ground to the top of the rear wheel well on both sides of the tow vehicle. Record these measurements.
3. Measure the Trailer Frame Height: Measure the distance from the ground to the top of the trailer frame, both at the front and rear. Record these measurements.

Step 4: Attach the Hitch Head

Attach the hitch head to the tow vehicle’s receiver. Ensure it is securely fastened and torqued to the manufacturer’s specifications. Use a torque wrench to avoid over-tightening or under-tightening the bolts.

Step 5: Connect the Trailer

Connect the trailer to the hitch ball and secure the coupler. Cross the safety chains and connect the breakaway cable. Double-check that all connections are secure.

Step 6: Engage the Spring Bars

Engage the spring bars by lifting them into the trailer brackets. This may require some effort, and you may need to use the hitch jack to raise the trailer tongue slightly. The tension on the spring bars is what distributes the weight, so this step is critical.

Step 7: Adjust the Spring Bar Tension

Adjust the tension on the spring bars to achieve the desired weight distribution. This is typically done by adjusting the number of chain links or the height of the trailer brackets. The goal is to return the tow vehicle's front fender height to approximately its original measurement.

1. Check Front Fender Height: After engaging the spring bars, measure the front fender height again. The goal is to return it to the initial measurement taken in Step 3.
2. Adjust Chain Links: If the front fender height is still lower than the initial measurement, add more chain links (increase tension). If it’s higher, remove chain links (decrease tension).
3. Adjust Trailer Bracket Height: Some weight distribution hitches allow you to adjust the height of the trailer brackets. This can also affect the tension on the spring bars.

Step 8: Verify Weight Distribution

After adjusting the spring bar tension, verify the weight distribution by measuring the fender heights again. The front fender height should be close to its original measurement, and the rear fender height should be slightly lower than its initial measurement. The trailer should also be level.

• Ideal Scenario: The front fender height is within ½ inch of its original measurement, and the trailer is level.
• If Adjustments Are Needed: If the front fender height is still too low, increase spring bar tension. If it’s too high, decrease spring bar tension. Repeat the process until the desired weight distribution is achieved.

Step 9: Test Tow and Fine-Tune

Perform a test tow in a controlled environment, such as an empty parking lot, to get a feel for how the vehicle handles. Pay attention to steering, braking, and sway. If you experience any issues, make further adjustments to the spring bar tension.

• Listen for Noise: Any unusual noises can indicate improper setup or adjustments. Check for binding or rubbing components.
• Evaluate Steering and Handling: The vehicle should steer smoothly and predictably. If the steering feels heavy or unresponsive, the weight distribution may not be optimal.
• Check for Sway: Trailer sway can be dangerous. If you experience sway, increase the spring bar tension or consult a professional.

Step 10: Final Check and Secure

Once you are satisfied with the adjustments, perform a final check of all connections. Ensure that all bolts are torqued to the manufacturer’s specifications and that safety chains and breakaway cables are properly connected. Secure any loose components and store your tools.
