Setting up trailer equalizer bars correctly is paramount for safe and comfortable towing, distributing weight evenly across your tow vehicle and trailer axles to prevent sagging, sway, and reduced braking performance. Achieving this involves precise measurement, careful adjustment, and a thorough understanding of your equipment’s specifications, ensuring a level ride and optimal handling. This guide will walk you through the process, step-by-step.
Understanding the Importance of Equalizer Bars
Equalizer bars, also known as weight distribution hitches, are designed to redistribute the tongue weight of your trailer from the rear axle of your tow vehicle to all axles – including the front axle of the tow vehicle and the trailer axle(s). This seemingly simple action has profound effects on vehicle stability and control. Without them, excessive tongue weight can cause the rear of your tow vehicle to sag, lifting the front wheels and reducing steering and braking efficiency. Furthermore, the unbalanced weight distribution increases the likelihood of trailer sway, especially in windy conditions or when encountering uneven road surfaces.
Benefits of Properly Adjusted Equalizer Bars
The benefits of using properly adjusted equalizer bars extend beyond safety. Here’s a breakdown:
- Improved Steering: By transferring weight to the front axle of the tow vehicle, steering response is significantly improved, allowing for more precise control.
- Enhanced Braking: Distributing weight evenly ensures all brakes are working optimally, reducing stopping distances and improving overall braking performance.
- Reduced Trailer Sway: The weight distribution minimizes the tendency for the trailer to sway, creating a more stable and predictable towing experience.
- Level Ride: A level ride improves comfort and reduces stress on both the tow vehicle and the trailer.
- Reduced Stress on Vehicle Components: Even weight distribution minimizes the strain on the tow vehicle’s suspension and chassis, prolonging their lifespan.
Step-by-Step Guide to Setting Up Equalizer Bars
Setting up equalizer bars requires patience and attention to detail. The following steps outline the process:
-
Determine Tongue Weight: The first step is to accurately determine your trailer’s tongue weight. This can be done using a tongue weight scale or by taking your trailer to a commercial scale. Your trailer manufacturer will also have this information. This weight is critical for selecting the correct equalizer bar rating.
-
Select the Correct Equalizer Bar Rating: Equalizer bars are rated based on their weight capacity. Choose bars with a capacity that matches or slightly exceeds your trailer’s tongue weight. Err on the side of slightly higher capacity rather than underestimating. Consult your trailer manufacturer’s recommendations if unsure.
-
Park on a Level Surface: Ensure both your tow vehicle and trailer are parked on a level surface. This is crucial for accurate measurements and adjustments.
-
Measure Tow Vehicle Height (Unloaded): Measure the distance from the ground to the top of the wheel well on both the front and rear axles of your tow vehicle before connecting the trailer. Record these measurements. These are your reference heights.
-
Connect the Trailer Coupler to the Hitch Ball: Carefully connect the trailer coupler to the hitch ball and secure it properly.
-
Measure Tow Vehicle Height (Loaded): After connecting the trailer, measure the distance from the ground to the top of the wheel well on both the front and rear axles again. Note the difference from the unloaded measurements. The goal is to return the front axle measurement as close as possible to its original, unloaded height.
-
Attach Equalizer Bars to Hitch Head: Attach the equalizer bars to the hitch head, ensuring they are properly seated and secured. Follow the manufacturer’s instructions for this step, as methods can vary.
-
Attach Equalizer Bar Chains to Trailer Frame Brackets: Connect the chains of the equalizer bars to the frame brackets on the trailer tongue. The number of chain links used determines the tension applied. Begin with a moderate number of links.
-
Raise the Trailer and Tow Vehicle with the Tongue Jack: Use the trailer tongue jack to raise both the trailer and the rear of the tow vehicle slightly. This makes it easier to tension the chains.
-
Tension the Chains: Use the equalizer bar tool (often included with the hitch) to tension the chains. Start with equal tension on both sides. As you tension the chains, lower the tongue jack to put weight back on the axles.
-
Re-measure Tow Vehicle Height: After tensioning the chains, re-measure the distance from the ground to the top of the wheel well on both the front and rear axles of your tow vehicle. Adjust the chain tension until the front axle height is as close as possible to its original, unloaded height. The rear axle height should also be close to its original height but may be slightly lower.
-
Fine-tune Adjustments: It may take several iterations of adjusting the chain tension and re-measuring to achieve the optimal weight distribution. Observe the trailer’s level and the tow vehicle’s handling.
-
Safety Check: Double-check all connections and fasteners to ensure they are secure.
Frequently Asked Questions (FAQs)
1. What happens if I don’t use equalizer bars when I need them?
Failing to use equalizer bars when necessary can lead to poor handling, reduced braking efficiency, increased sway, and potential damage to your tow vehicle and trailer. It compromises safety and puts undue stress on your vehicle’s suspension.
2. How do I know if my equalizer bars are the right rating?
The equalizer bar rating should match or slightly exceed your trailer’s tongue weight. Consult your trailer and hitch manufacturer’s specifications for guidance. A too-light rating won’t provide sufficient weight distribution, while an excessively heavy rating can result in a harsh ride.
3. How tight should the chains be on my equalizer bars?
The chains should be tight enough to return the front axle of your tow vehicle as close as possible to its original, unloaded height. However, avoid over-tightening, which can cause a harsh ride and excessive stress on the hitch components. Re-measuring after each adjustment is crucial.
4. Can I use equalizer bars with a surge brake system?
Yes, but special considerations may be needed. Some surge brake systems require a sway control device specifically designed for surge brakes to avoid interference with their operation. Consult your surge brake manufacturer for compatibility recommendations.
5. What tools do I need to set up equalizer bars?
You’ll typically need a tongue weight scale, tape measure, socket set, wrench set, an equalizer bar tool (usually included with the hitch), and a level. Some hitches may require specialized tools.
6. How often should I inspect my equalizer bars?
Inspect your equalizer bars before each towing trip for signs of wear, damage, or loose connections. Pay close attention to the welds, chains, and mounting hardware.
7. What is the difference between sway control and weight distribution?
Weight distribution redistributes tongue weight to improve handling and braking, while sway control specifically resists trailer sway. Some equalizer hitches incorporate both weight distribution and sway control features.
8. Can I use equalizer bars with all types of trailers?
Equalizer bars are typically used with travel trailers, campers, and utility trailers with significant tongue weight. They may not be necessary for smaller, lighter trailers.
9. How do I adjust the height of my hitch ball?
The height of your hitch ball should be adjusted so that the trailer sits level when connected. This often requires adjusting the height of the hitch receiver or using a different drop hitch.
10. What if my tow vehicle still sags after using equalizer bars?
If your tow vehicle still sags excessively even with properly rated and adjusted equalizer bars, you may need to upgrade your tow vehicle’s suspension or reduce the trailer’s tongue weight.
11. Are equalizer bars universal, or do I need a specific type for my vehicle?
While many equalizer bars are adaptable, it’s crucial to ensure compatibility with your tow vehicle’s hitch receiver and your trailer’s coupler. Some vehicles may require specific hitches or adapters.
12. Where can I find the tongue weight of my trailer?
The tongue weight is typically listed on a sticker or plate on the trailer itself. You can also consult the trailer manufacturer’s documentation. If you’re unsure, it’s best to have it professionally measured.
By following these guidelines and regularly inspecting your equipment, you can ensure a safe and enjoyable towing experience with your trailer equalizer bars. Remember, safety is paramount, and professional assistance is always recommended if you are unsure about any aspect of the setup.
