X and the first number is trailer weight, second number is tongue weight. It has been described to me many times that the weight distributing hitch (with 'stabilizing/leveling' bars) 'takes weight off the rear axle of the tow vehicle and puts it on the.' >

    Weight Distributing Hitches Heavy tongue weight tends to pull your tow vehicle's rear end down and lift the front end up. This causes an uneven and less stable ride. This problem can be eliminated by using a weight distributing hitch, also known as a load equalizing hitch. Measuring weight distribution setup well does not ensure safe towing. The operator is responsible for making necessary adjustments to the hitch to optimize weight distribution and sway control. Each trip is different, and the weight distribution setup and towing performance should be evaluated by the operator and adjusted when necessary.

      Weight distribution hitch. The summer is almost upon us, and so is the recreational towing season. This is the time when many take to the highway with a camper, or boat trailer, or both.   A weight distribution hitch with sway control is preferable, as it eliminates any bumps, dips, preventing lane wandering and any collisions with the nearby vehicles.

Final report. The use of a weight distribution hitch by itself may help limit trailer sway by evenly distributing the weight of the load, but it will do little to improve sway caused by crosswinds.

That's where sway control comes in. Some weight distribution hitches have built-in sway control. A weight distribution hitch (or weight distribution system) helps to ensure a smooth, level ride and allows you to tow at the maximum capacity allowed by your hitch. It also helps to correct tow vehicle sag, improve steering and stopping, and—when used with sway control—correct trailer sway.

Combined weight means the weight of both the tow vehicle and the trailer together. It also includes any cargo or load placed in either vehicle.

The rating for gross combined weight or gross combination weight is determined for the vehicle based on the strength of its frame, suspension, axles and other towing-related components. Due to the leverage applied, the weight added to the rear axle will always be higher than the actual tongue weight.

By using a weight distribution hitch (Case 2), the torque bars on the hitch will reduce the applied leverage, moving weight from the rear axle back to the front steer axle and trailer axles. The effect is to reduce the tongue weight. Weight Carrying Hitch. Weight Distribution Hitch (Equal-i-zer brand), which has spring bars to remove some of the weight from the tow vehicle’s rear axle and distribute it to both the tow vehicle front axle and the trailer’s axle.

They feature a 2" x 2" receiver tube opening and generally have a weight carrying capacity up to 10, lbs. gross trailer weight. Most class 4 hitches can also utilize a weight distribution hitch.

A weight distribution (WD) hitch uses torque or rotational force to transfer the load. The load is transferred to the tow vehicle's front axle and the trailer's axle.

Considering the value of the horses and the weight of a loaded horse trailer, we recommend using an e2 weight distribution hitch when towing a horse trailer. If you are towing a tall recreational vehicle trailer or a heavy enclosed trailer, which can get blown around by high crosswinds, we recommend using sway control, which helps eliminate.

Just remember that the trailer acts like a lever, and the axle of the trailer is the fulcrum-- or pivot point -- for the the tongue is too light, you need to move some of the cargo forward of trailer's axle.

If the tongue is too heavy, you need to adjust the load so that more of the weight is behind the trailer's axle.

One addition that can also help with hitch weight is a special hitch called a weight distribution hitch. This type of hitch has spring bars, or equalizing bars, in it which allows leverage between your vehicle and the camper, subsequently dispersing some of the weight off the back axle to the axles of the camper as well as the front axle of the.

Having too much tongue weight in relation to gross trailer weight can cause the hitch of the trailer -- and the rear axle of the tow vehicle -- to dive, meaning the front of the trailer will head toward the ground, bringing the front of the towing vehicle off of the sly, if your tow vehicle dives too far, such as in situations when you need to brake quickly, you'll loose braking.

The weight distribution hitches correct this by distributing the weight across the axles of the trailer and vehicle just like lifting a wheelbarrow. Check the image below it shows how a tow vehicle and a trailer would look like if you end up buying the wrong weight distribution hitch or if you travel with your trailer without a hitch.

Benefits of a Weight Distribution Hitch. A weight distribution hitch can help regardless of the trailer. However, if your trailer weighs over 5, lbs., you’d have to have it installed. But if you have a heavy-duty truck, this threshold can go up to between 6, and 8, lbs.Proper Weight Distribution is required for towing stability and will assure that the trailer is not rear, front or side heavy.

A light tongue weight or heavy weights placed at the rear end of the trailer can cause sway. On the other hand, too much weight on the tongue can overload the tow vehicle and cause poor tow vehicle braking, poor cornering and can damage the trailer frame.
