The best weight distribution hitch is the Blue Ox BXW1500 SWAYPRO, which has a 1,500 LBS tongue weight and a 15,000 LBS gross trailer weight and simply clamps onto standard couplers with no fine tuning needed as the hitch head is pre-adjusted.

When investing into a weight distribution hitch, we highly recommend that you choose one with sway control. Reducing trailer sway will make you more relaxed whilst towing as when your trailer is swaying, it can be scary and dangerous.

There are two weight ratings that you must understand before purchasing a weight distribution system. These are Gross Trailer Weight (GTW) and Tongue Weight (TW). GTW is basically the gross weight of the trailer and its load, whereas TW is the weight of the trailer and cargo that is behind the rear axle of  your towing vehicle.

If you are regularly towing, then you really should invest into one of these systems. Below is a list of the best weight distribution hitches that include sway control and simply clamp on to most standard couplers.

Blue Ox BXW1500 SWAYPRO Weight Distributing Hitch

The Blue OX SWAYPRO is a premium weight distribution hitch, which includes a top of the range sway control system and is compatible with most electric trailer brake controllers. The BXW1500 includes a pre-adjusted hitch head and it will simply clamp on to most standard couplers.

In terms of the Blue Ox BXW1500 SWAYPRO weight ratings, it has a gross trailer weight of 15,000 LBS and tongue weight of 1,500 LBS.

As the name of this weight distribution hitch suggests, there has been plenty of development gone into the sway control. This is thanks to chain-link adjustable torsion bars and excellent design, which makes trailer sway non existent.

Another benefit is that the chains do not need to be removed when backing up, which is a desirable trait as it can be frustrating having to remove these chains.

Compared against the alternatives, the Blue Ox BXW1500 SWAYPRO is expensive but it is definitely worth paying extra. It is the best weight distribution hitch you can buy with excellent sway control and weight ratings.

Weight Distribution Hitch Buying Guide

If you are towing heavy trailers with big loads or large caravans, a weight distribution hitch should be used. This is because it will provide a smoother ride that wont suffer from trailer sway, bad steering or poor stopping abilities. It is advised that if your trailers weight is over 50% of your towing vehicles weight, you should use a weight distribution system.

When you are towing a trailer, the tongue weight is transferred to the rear axle of your towing vehicle, which will result in the rear sagging and the front raising. This will cause performance issues with the car and it will not act as it would normally. Steering, braking, traction and other issues will become apparent and for long journeys, it can be very tiresome and dangerous.

We have put together a buying guide that goes through everything you need to know regarding weight distribution hitches and sway controls below.

How Does Weight Distribution Work?

Spring bars leverage each side of your system by transferring the load that pushes down at the rear of the tow vehicle to all the axles of both the trailer and vehicle. The result is an even distribution with no sagging of the rear of the tow vehicle whatsoever and a completely smooth ride. Below are some of the signs that you need a weight distribution hitch:

  • Rear is sagging
  • Front is raised
  • Steering or braking is difficult
  • Large amount of trailer sway
  • Trailer weight is over 50% of the vehicles weight

Some vehicles may have a hydraulic or air rear suspension, which can level the rear of the car. This is a great feature but if you have a trailer that is over 50% of the weight of the tow car, it is still highly recommended. Not only for performance purposes but also to take some of the slack of your cars rear suspension as most hydraulic or air suspension system can be very expensive to repair.

What is Sway Control?

You will notice that all the weight distribution hitch recommendations have a sway control system. The reason is because trailer sway can be worrying and can be caused from passing other vehicles, crosswinds, bad spring bar tension, poor trailer loading and other reasons. The majority of weight distribution hitches uses the 4 following built-in systems as sway control:

  • 2 Point
  • Friction
  • Dual Cam
  • 4 Point

All the recommendations above are a weight distribution hitch with sway control built in, which means there is no need to install it separately.

Trailer sway is not fun and a bad experience of it can put you off towing for good. If sway control is the number one priority, we highly recommend the Equal-i-zer as it has the best sway control with a 4 point system.

Swing Bars

The swing bars are a major component of any weight distribution kit and without them, it would be impossible to leverage the weight. There are however two types of swing bars, which include rounded swing bars and trunnion swing bars.

The benefit of rounded swing bars are that they are easier to install, setup and also provide much more clearance. However, the trunnion swing bar alternative will provide a much higher weight rating, which is a big requirement for many.

Weight Capacity Ratings

In the table at the beginning of this article, you will notice that each weight distribution hitch has a tongue weight and gross trailer weight rating. Usually, the tongue weight is around 10 to 15% of the gross trailer weight.

The gross trailer weight (GTW) is the easiest to define and is quite simply the total weight of the trailer that includes the load on the trailer too. Tongue weight (TW) is the weight that behind the axle of the towing vehicle and too much of this weight causes the towing vehicle to sag. Too little tongue weight makes the trailer more prone to swaying and jack knifing.

Finding the perfect GTW or TW is dependent upon what you intend on loading upon your trailer. However, a weight distribution hitch with sway control is the answer to conquering all these dangerous scenarios and will ensure you have a smooth ride.

If the GTW of the distribution systems are too little for what you intend to be towing, then there is an alternative. A 5th wheel hitch can be used to tow trailers as heavy as 25,000 LBS but it will require a truck to be able to install such a hitch.

Conclusion

Towing anything on the open road needs to be done with great caution. Upgrading from a standard trailer hitch to a weight distribution hitch system is highly recommended for heavy loads. Trailer sway is a worrying thought regardless of your towing experience because at any moment during the sway, you may lose control of your vehicle.

Along with purchasing a weight distribution hitch, you should also be looking at sway control systems. All of the hitches in this article have them built-in but many do not, so if you do not go with one of the above, be sure to read the full specification.

Once you have your weight distribution hitch installed, remember to use a trailer hitch lock to secure the load and you ensure it has been tuned properly. Many come with pre-installed hitches that require no fine tuning.
