Create a stable ride for your tow vehicle and trailer with a weight-distribution hitch. Adding spring bars to your towing system applies leverage, which transfers the load that is pushing down on the rear of your vehicle to all the axles on both your tow vehicle and your trailer, resulting in an even distribution of weight throughout. The result is a smooth, level ride, as well as the ability to tow the maximum capacity of your hitch.
Selecting a Weight-Distribution System
The tongue weight rating is the most important factor in determining which size weight-distribution system you should use. If the bars of the system you choose are rated too high for your setup, they will create a rigid ride, which can result in a bouncing trailer. If, on the other hand, the bars are not rated high enough, the system will be unable to properly distribute the weight, rendering it virtually useless.
To determine the proper weight rating for a weight-distribution system, you must first determine your trailer's tongue weight. Then add to that the weight of the cargo behind the rear axle of your tow vehicle. These two measurements make up the tongue weight rating for a weight-distribution system.
Unique Features of Pro Series Round-Bar Weight Distribution
To adjust your weight-distribution head assembly to the correct angle, insert the included rivet and up to 8 washers into a 1/2-inch hole in the "U" on your head assembly. Use the smallest number of washers necessary to achieve the correct downward angle for the spring bars. Each washer lowers the chain ends of your spring bars by approximately 1-1/2 inches. Once the correct angle is reached, use the included bolts, serrated washers and nuts to lock the unit into place.
The round spring bars of this system slide up into the weight-distribution head and are secured with built-in, spring-bar locking devices for quick, easy installation. With a tapered design and forged steel construction, these bars flex to ensure a smooth, controlled ride for both your tow vehicle and your trailer.
Friction Sway Control
The integrated friction-style sway control of the Pro Series system reduces trailer sway caused by winds, winding roads and sudden maneuvers. As soon as your trailer begins to move out of line, the friction pads inside the unit touch one another and create resistance to help prevent further side-to-side movement. To install, simply bolt the sway-control ball plate to the A-frame of your trailer and attach the other end to the included ball, which mounts on the head of your weight-distribution hitch - drilling required. The ball plate mounts to the side of the trailer frame so it will not interfere with gas tanks, toolboxes or generators.

Shipping slow this time. Usually a lot faster with products. Hitch heavy duty for vehicle but maintained stability and worked flawlessly when towing. Small light Nissan SUV married with 3500lb utility trailer. Mfgr includes a ball but I required a 2 inch ball. Extremely hard to remove (overtightened from mfgr) and needed a local mechanic with better tools. Will not use as regular hitch because of weight. When having car and trailer with max weight, it is a necessity. Surprisingly easy to set up and change. Instructions were correct and easy to understand. Sway control helpful with desert winds, highway truck grooves, and highway speeds; just tighten a little more.78010
The weight-distributing hitch is well made and was delivered much more quickly than anticipated, which was great. While not cheap, the price was a good deal lower than the competition. The product is very heavy, and handling damaged the cardboard box in transit. Fortunately, it comes well packed, so nothing was lost from the box. I do wish the unit had not come with the ball mounted, as one of the things I have to do is find tools to swap the mounted ball for the smaller ball for my 16' Casita travel trailer.66090
Great website - easy to navigate, lots of information helped me decide which hitch was right for me.
Great company - excellent price, shipped quickly with lots of communication and follow-up. I will not hesitate to recommend.62383
I have used this system on a few trips now and it works very well. One trip was over 6 hours each way using back roads and hiways. It was easy to setup, install, and use. My only complaint is that it has a lot of adjustment room to raise it above the reciever, but vey little room below. I would like mine to be one or two holes lower.56861
This product is great.Works really good.Easy to install and adjust.Quality and well built.Im really happy with my purchase,and customer service at etrailer.com.And its a complete package,with sway control.Free shipping also.Cant beat it47535
Works as expected. Only major complaint was that bolting the ball mount REQUIRED an air wrench - which no longer made it a DIY job to assemble for me.39677
When choosing a weight distribution system, ideally the tongue weight of the trailer will fall right in the middle of the effective range of the system.
Make sure that the tongue weight figure you use includes the fully loaded and ready to tow tongue weight of the trailer. The weight of anything stowed behind the rear axle of the tow vehicle also needs to be included in the tongue weight figure. If the 405 lb TW figure you mentioned represents the dry tongue weight that does not include the w view full answer...
I do recommend weight distribution for your truck and trailer. First, the empty weight of the trailer is 4,800 pounds so when loaded and ready to tow it will be over 5,000 pounds. Your 2004 Chevy Silverado 2500HD is more than capable of towing the weight, but the truck would have to way over 10,000 pounds for it not to follow that 50 percent guideline you have mentioned. It is actually 50 percent of the vehicle weight. Not 50 percent more than the vehicle.
With a tongue weight of 800 pounds, view full answer...
On a boat trailer, you will need to use a pole tongue adapter, # RP58393, to mount the sway control and weight distribution brackets. Since a lot of boat trailers are aluminum, not all of them can be used with weight distribution and sway control. You will need to contact the trailer manufacturer to determine if your trailer can be fitted with weight distribution and sway control.
If it can, then using the pole tongue adapter requires a certain weight distribution system, a Reese SC system. Y view full answer...
Based on the excellent information you provided, the the total tongue weight (tongue weight of trailer plus cargo behind vehicle rear axle) will range between 450-550 lbs.
I will proceed on the assumption that your boat trailer has a straight, or pole tongue versus an A-frame as is typical for a boat trailer.
If your boat trailer uses a hydraulic surge coupler that compresses to actuate the trailer brakes, you will not be able to use a standard chain-suspended type W/D system like the # PS view full answer...
Tongue weight is typically 10 to 15 percent of the gross vehicle weight plus the weight of anything loaded behind the rear axle of the tow vehicle. That would about 173 to 260 pounds for the trailer. If that 500 pounds is all behind the rear axle of the Explorer, the total tongue weight would be between 673 and 760 pounds. A weight distribution would be beneficial.
If you determine that the tongue weight is between 200 and 600 pounds, I would go with a system like # RP66151. This will give yo view full answer...
I do not think the trailer is too heavy but weight distribution and sway control will help. When choosing a weight distribution system, you will need to go by the tongue weight of the trailer loaded and ready to tow and then add the weight of anything loaded behind the rear axle of the tow vehicle.
For a 2,700 pound trailer and nothing loaded behind the rear vehicle axle, that would be the tongue weight at 270 to 405 pounds. The Pro Series systems that include sway control are rated too high view full answer...
The Pro-Series weight distribution system # PS49901 comes with a 2-5/16 inch ball. For a 2 inch ball you would need to add # A-90. You would have to remove the 2-5/16 inch ball from the head and then attach A-90 according to specs in the instructions attached to the ball.
Both the 2-5/16 inch ball and A-90 come with wrench flats so you will be able to use properly sized wrenches to remove/install a ball. If you do not have the tools readily available some auto parts stores will loan out tools view full answer...
When choosing a weight distribution system, ideally the tongue weight of the trailer will fall right in the middle of the effective range of the system. It is important that you find the tongue of your trailer when it is fully loaded and ready to tow and that you also include the weight of any cargo loaded in the bed of your 2009 Ford F-150 STX behind the rear axle. Since a weight distribution system distributes the weight from the rear axle to all axles, the weight of additional cargo behind th view full answer...
The first step in choosing a weight distribution system is to definitively identify the fully-loaded and ready to tow tongue weight of the trailer. There are a few methods of doing this, as you can see by clicking on the link I provided.
Knowing the exact tongue weight is a crucial step in choosing the correct system for your application. If you choose a system that does not have a high enough capacity, the system will not be effective and could be damaged. Choosing a system whose capacity is view full answer...
Because your trailer has a C-channel frame, the Pro Series system you referenced, # PS49901, would be a good choice. It is rated for up to 550 pounds tongue weight and has lift up brackets that will work with the C-Channel frame. Also you will want to make sure that the 550 pound capacity of this system will be enough.
Tongue weight is calculated by taking the trailer tongue weight, when loaded and ready to tow, then adding the weight of anything carried behind the rear axle of the tow vehic view full answer...
There are a few reasons why you might appear to need longer chains. First, it should be noted that typically you want 5 links from the hanger to the chain. There are several factors that could lead to the chains not being long enough. First, if you have a tall frame, you may need more links so that the bars are not making contact with the frame. If the frame is taller than 6 inches, you will want to use different chain hangers, # RP58305.
Another factor that could lead you to believe longer view full answer...
Since you already have air bags on the truck, I would not add a weight distribution system because doing so can cause the two items to work against each other and diminish the benefits. Ideally, if the trailer is causing the vehicle to sag, weight distribution is the ideal solution over air bags.
With the air bags installed, the truck should really not be sagging any more. So if it is now just an issue of towing the trailer level you will just need the appropriate rise or drop ball mount. I h view full answer...
