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).

Do you have a question about this Weight Distribution?
- Experiencing Awful Noise When Backing With Reese High Performance Weight Distribution System
- Experiencing awful noise when backing with the Reese High Performance Trunnion System, item # RP66021, is not normal. First I would recommend greasing your hitch ball and trunnion ends. Second you should check the clearance of your spring bars. You should have 5 to 6 links between the snap up hook and the spring bar when hooked and ready to tow. To adjust this, if you need to, you will have to adjust the angle of the weight distribution head and hitch ball.

- Availability of Replacement Parts for Reese Weight Distribution System # RP66021
- The pieces that came off your weight distribution/sway control system could be several things, depending on which end the pieces came from and if they came from a sway control component or a weight distribution component. Either way, you do not want to tow your trailer with a naked bar until the problem is fixed.
If it came from the spring bar and it is the end that goes into the weight distribution head, it is probably the trunnion, like # 58098. This is the part that holds the spring bar in

- Determining Maximum Weight of Trailer That Can be Towed by 2005 Excursion 4x4 Diesel
- To determine the maximum trailer weight that can be towed, you will need to subtract the GVW (gross vehicle weight) from the GCWR (gross combined weight rating). The GVW is the curb weight of the vehicle, plus the cargo. GCWR is the maximum allowable weight for the trailer plus the tow vehicle.
Given the figures you provided, when the GVW is subtracted from the GCVW, 11,500 lbs is the result, and would represent the maximum amount the trailer plus its contents can weigh.

- Weight Distribution System for 28 ft Travel Trailer and Stock Trailer Towed by 2010 F150 4x4
- We typically calculate trailer tongue weight as 10 to 15 percent of the GTW. Anything stowed in the tow vehicle behind the rear axle needs to be added to the tongue weight figure. Given the 7700 gross trailer weight of the travel trailer you mentioned, your tongue weight can range between 770 and 1100 lbs. For this range of tongue weights, I would recommend the Reese Heavy-Duty Trunnion Bar System, part # RP66542. This system is effective on trailer tongue weights ranging from 600-1200 lbs. The

- Adjusting Weight Distribution System to Eliminate Vehicle Sag
- Assuming that the weight of your camper does not exceed the capacity of the spring bars, a combination of tilting the weight distribution head rearward and tightening the chain hangers by one chain link at a time should distribute more tongue weight toward the front axle of the vehicle, thus lessening the sag at the rear bumper. If there are less than 5 links between the snap up bracket and u-bolt connecting the chains to the spring bar, adjust ballmount angle rearward.

- Cargo Trailer Pulls Up On Ball and Makes a Lot of Noise Over Bumps at highway Speed
- It does sound like the tongue weight was not high enough. If a trailer is empty, you can experience some of these symptoms. The tongue weight of a trailer should be between 10 and 15 percent of the gross trailer weight. For example if your trailer was fully loaded and weight 7,000 pounds, the tongue weight should be between 700 and 1,050 pounds.
Proper loading of the trailer will also help. Heavier items should be centered at the bottom and you would not want one side carrying more weight tha

- Weight Distribution Recommendation for a 1999 GMC Yukon SLT
- To determine the towing capacities of the 1999 GMC Yukon and if they change with the use of weight distribution, you will need to look at the owners manual in the towing section. The hitch itself on the vehicle should have a sticker that lists the capacity.
You are 100 percent correct, you will want to stay within the capabilities of the vehicle. If the hitch is rated lower, then you will go by its capacities. Always go by the lower rated component in any given system.

- Weight Distribution for a 2003 GMC Towing a Trailer
- Although you are getting fairly close to capacity, you should be able to tow that trailer. Keep in mind, that you will only be able to load 700 lbs of gear on that trailer, before you exceed that limit. Although in your instance, a weight distribution (W/D) system would not extend your vehicle's towing capacity, you might still benefit from using one. A W/D system would help eliminate any sqat in the rear of your vehicle that your experience with the trailer hooked up. Using a W/D system can als
