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 Reese Trunnion-Bar Weight Distribution
The easy-to-use, serrated washers on the Reese system make adjusting the tilt of the weight-distribution head a snap. This is a huge improvement over the standard pin-and-washer method, which involves piling washers - one on top of another - onto a difficult-to-access pin. The serrated-washer system lets you easily loosen, adjust and tighten a single washer and nut on either side of the head for simple, secure positioning.
The trunnion spring bars of this system slide into the weight-distribution head for quick, easy installation. With a tapered design and hot rolled steel construction, these bars offer superior flex, ensuring a smooth, controlled ride for both your tow vehicle and your trailer. In addition, these specially designed bars have rounded, hooked ends, making them the only kind of spring bars that can function with Reese's active-style, dual-cam sway control (sold separately).

This part is good for 1,200 pounds tongue weight and 12,000 pounds trailer weight. Before we start we need to take care of a few preliminary steps, first its good to get the trailer in line at a nice level spot then take it apart and get some measurements off of it and well show you what measurements you need. The first measurements we need are on the truck itself. Were going to measure from the top of the wheel well down to the ground. The reason for these measurements is to make sure we get the truck back to its original height or as close as possible. Finally we need the coupler height with the trailer level on the ground. Just to make sure we need to measure from the ground to the top of the wheel well. On the front wheel we have 39-1/2 inches, and at the rear axle we have 41-1/2inches. from the ground to the top of the coupler we have about 23 inches.
Go ahead and write those measurements down on the blanks of your instruction sheet for reference later on. To start off the assembly we need to put the shank into the truck and put our head assembly on the back, loosely, and attach our ball. When installing our shank here, were going to do a quick estimate where its going to lay at, chances are were going to have to adjust it up or down. For now were just going to hold it in place. Were also at this point going to install our adjustment washers, well start off with six washers and we can always adjust it from there. Next well install the ball on here and to make it easier we will turn this sideways. Well install our 2-5/16 ball, which is part number 19286. Next were going to install the chains on our spring bars and we do that by putting the chain up to the spring bar, ing a u-bolt and putting some nuts on to hold it in place. When you tighten these down, you run the threads past the nut is all it takes. You just have to make sure this has plenty of movement. Now repeat for the other side. Next were going to couple up the truck and the trailer. We did leave the head assembly loose, which well tighten down as one of the last things we do. Next we install our spring bars and start getting those adjusted up. Before we install our lift lock brackets, we the tightening bolts that go in here. Sometimes the paint gets a little thick in there, so you might have to use a wrench to run them through. Really all this bolt does is hold everything in place. Optionally you can use these two bolt holes to permanently attach these to your trailer if you want, but its not a have to deal.
Now we need to position the lift lock brackets. You need to pull the spring bar up some you wont get too far, but pull chain as vertical as you can. Align the bracket with the center of the chain. At this point we can tighten the bracket down to the frame. Now well repeat for the other side. It looks like theres some cables in the way so well undo this to make room for it. Once we have the cables out of the way we can install our bracket. Now we can make the springbar chain connection. With the lift unit in the raised position, well pull on the chain and note which link is closest to the hook. Well note which one it is and go down two links and use that one for the hook up. Now well jack up the trailer on the ball pulling up the truck at the same time to take tension off and making it easier to hook up the chains. Now repeat for the other side. One thing to make note of is to make sure you have five links minimum. That way you have plenty of room for the chain to move in between turns. Next we our safety clips, then well lower the jack and let it carry the weight. Well adjust the hook up if necessary, we need to check and make sure the ride height hasnt changed that much. We need to check the opening at the fronts original uncoupled dimension and compare it to what we have now. 39-1/2 inches is the original dimension, and we have 39-1/2 still. The rear should be slightly lower, originally it was 41-1/4 and I have 39-3/4. About a half an inch which is acceptable. It looks like weve chosen the right weight distribution, now well tighten down the bolts on the head assembly. With our head bolts tightened down and our head screw tightened down, all in all were ready to tow. If the measurements didnt come out right, one thing wed have to do is remove some of the washers on the top or add some to achieve the proper tension we need. That covers it for part number 7903 the Draw-Tite weight distribution assembly for our 1200 pounds tongue weight and 12000 pounds trailer weight.

Ask the Experts about this Reese Weight Distribution
Do you have a question about this Weight Distribution?
- Is Towing without a Weight Distribution System Safe?
- You have 3500 lbs to play with here, so towing that trailer should not be a problem. You do not need the w/d system to extend the towing capacity of the hitch, but the systems do have other benefits. Because a w/d system removes some of the tongue weight from the rear axle and transfers it to the front axle of the tow vehicle, using the system can increase performance in steering, traction, and stopping while also decreasing trailer sway.

- Which Spring Bars Would be Best 600 lb or 800 lb For Dodge Ram 1500 4x4 and Starcraft Hybrid Antiqua
- When determining the correct spring bars for your trailer you will need to take into account the weight of gear loaded behind the rear axle of the truck and the additional tongue weight loaded in the camper.
I believe larger is better but in your case the 1,200 pound bars are too stiff if they are causing the ride to be uncomfortable. I would go with the 800 pound spring bars, item # RP22225, since you will have gear behind the rear axle and gear to load into the camper.

- Correcting Sway on 24 Foot Camper Towed By 2007 Jeep Grand Cherokee
- For trailers exceeding 25 or 26 feet in length, using two friction sway controls with one being installed on each side of the trailer is recommended. Since you are so close to that length, going with two units would certainly help. However, when the short (relatively speaking) wheel base of your Grand Cherokee is considered, I do not believe friction sway control will solve your issue.
A friction unit will resist sway once it has started. The dual-cam approach actually forces the trailer to r

- Will Using a Weight Distribution System Increase Towing Capacity of Vehicle
- An equalizing hitch or weight distribution can sometimes increase the capacity of the receiver hitch, but the vehicle manufacturers stated towing capacity or rating will always be the final determination of how much the vehicle can tow. Any towing system will only be as strong as its lowest rated component.
I would urge you to abide by the stated towing capacity of your truck. Failure to do so can cause the hitch to fail or damage drive train components on the vehicle.
