Weight Distributing Hitch

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.

Product was great but the service was better!!! The carton arrived apparently damaged by the carrier with multiple pieces missing. The e-trailer staff had replacement parts sent immediately and they arrived two days later. The transaction was taken care of by e-trailer without any hesitation. Service better than I receive at many places in person. Well Done e-trailer. 239571

Do you have a question about this Weight Distribution?


  • Weight Distribution Hitch for Short A-Frame Trailer Tongue
  • It seems like you have the basics of choosing an effective weight distribution system down, but just to be thorough it bears repeating that in order to choose the best weight distribution system, you will first need to know your total tongue weight (TTW), which is the tongue weight of your fully loaded and ready to go trailer plus the weight of any cargo behind the rear axle of your 2017 Nissan Armada. Since your trailer weighs 4,550 lbs fully loaded, depending on how much weight you...

  • Weight Distribution System for Towing a Snowmobile Trailer with a Minivan to Eliminate Ups and Downs
  • We have just what you are looking for. You would need to install a pole tongue adapter, # RP3280, on the long straight tongue on your snowmobile trailer. Before using a weight distribution system be sure to check your vehicle owners manual and trailer hitch to make sure they are compatible with weight distribution. Once you have the adapter installed, you will be able to select a weigh distribution system that is compatible with your snowmobile trailers tongue weight and gross trailer...

  • Comparing Curt # C17331 Short-Arm vs # 17301 Standard Length Spring Bar Weight Distribution Systems
  • The only difference between the Curt # C17331 and the # 17301 weight distribution systems is the length of the spring bars. The Short-Arm system is designed for trailers that have batteries or propane tanks on the trailer tongue, where there is a limited amount of space on the frame member. Either system is designed for trailers whose total tongue weight (trailer tongue weight plus weight of cargo in truck bed or SUV cargo area behind rear axle) doesn't exceed 800 lbs.

  • Are Shorter Spring Bars Available for the Reese SC Weight Distribution Systems
  • We do carry weight distribution systems with shorter spring bars, however, all of the spring bars for the Reese SC weight distribution systems are the same size. Unfortunately, they do not make shorter spring bars for this system. Instead, I recommend looking at the Curt Short-Arm Weight Distribution Systems. These systems are available with tongue weight capacities of 600 lbs, # C17330, 800 lbs, # C17331, and 1,000 lbs, # C17332, and they each have a maximum towing capacity of 10,000...

  • Is Curt 1,000 Pound Weight Distribution System Rated too High for 6,250 Pound Boat Trailer
  • Curt weight distribution system # C17322 is rated for 800 to 1,000 pounds tongue weight so it would be overkill for your trailer unless you also have weight behind the rear axle of the towing vehicle that increases the tongue weight to at least 800 pounds. There is a similar Curt system, # C17330, rated for 500 to 600 pounds tongue weight and another, # C17331, rated for 600 to 800 pounds. To choose a weight distribution system you will need to go by the total tongue weight of the...

  • Recommendation for Cargo Carrier that Sits Nose High with Weight Distribution System
  • To add a drop from the trailer hitch on your 2017 GMC Sierra 1500 when using the Curt Short-Arm Weight Distribution System # C17331 referenced in your question, I recommend using the Curt Welded Weight Distribution Shank # C17123. This is an adjustable shank with 10 bolt holes, spaced 1-1/4 inches apart, that will allow you to adjust the drop with your trunnion bar weight distribution system. The maximum drop it will give you is 6-1/4 inches. I have attached a short demonstration video...

  • How Long are the Curt 800 Pound Weight Distribution Trunnion Spring Bars
  • Curt trunnion springs bars # 17305 are 30-5/8 inches long. They are the same bars that are in weight distribution kit # 17301. Curt also has a short arm system # C17331 with bars that are 28-5/8 inches long.

  • Ball Hole to Frame Bracket Dimension for Curt Short Arm Weight Distribution System
  • The spring bars of the Curt Short Arm System part # C17331 are 28-3/8 inches long. The chain hanger brackets will be centered 28-3/8 inches back from the center of the ball hole. If you have a clearance issue on your trailer frame you could use the bolt on brackets part # C17005 instead. These will bolt to the side of the trailer frame and will not require clearance above the trailer frame.

  • Can Curt Friction Sway Control be Used on Curt Short Arm Weight Distribution System

  • Installing a 7-Way Connector and a Brake Controller on a 2011 Ford Escape XLT
  • Yes, the Universal Wiring Kit # ETBC7 and the Tekonsha Prodigy P3 # 90195 will also fit your 2011 Ford Escape. If you already have a 4-Way then you won't need anything else, however if you don't have a 4-Way then you will need part # 118251 if you have the factory tow package or part # 118551 if you don't have the factory tow package. Attached is a sample installation video of the ETBC7 kit being installed on a 2011 Escape for you to reference. The brake controller being installed is...

  • Installing a Weight Distribution System on a V-Nose Trailer
  • Using a weight distribution system on a V-nose trailer can be tricky. One option is to use a system with short arms like the Curt # C17331. Systems like this are designed for trailers with a short tongue. Another option is the Reese Chain Hangers # RP58305. These bolt to the side of the trailer's frame and replace the brackets that are normally installed around the frame. If you can provide me with the trailer's loaded, and ready to tow tongue weight I can make a recommendation...

  • Weight Distribution Recommendation for Trailer that Weighs 10,000 lbs with V-Nose
  • Since your trailer has a V-nose where most of the frame is under the trailer you'll need to use a set of bolt on brackets for the chain hangers like the # C17005. The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well....

  • Short Arm Curt Weight Distribution System Recommendation for V-Nose Trailer
  • You'd need to go with a Short Arm Curt weight distribution system like the part # C17330 which has a 600 lb tongue weight max, the # C17331 for if you need an 800 lb max TW rating, or # C17332 for if you need a 1,000 lb tongue weight max system. The bar of this kit are only 28-3/8 inches long which would work well with your frame clearance that has the V-nose at around the 32 inch mark.
