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.


Serrated Washer System

Unique Features of Reese Strait-Line Weight Distribution

The easy-to-use, serrated washers on the Reese Strait-Line 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 the Strait-Line 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. 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.


Weight Distributing Hitch

Dual-Cam Sway Control

Reese's dual-cam sway-control system stops trailer sway before it begins. This is a significant improvement over traditional friction-style controls, which help to correct sway only after it has already begun. This specially designed system uses unique sliding devices called "cams" to suspend the spring bars of your weight-distribution system. One end of a cam bolts onto your trailer's frame, and the other end attaches to the lift bracket via the lift chain. The rounded, hooked ends of the spring bars then sit in these cams. The controlled placement of the spring bars keeps your system secure while still allowing enough movement for free, easy interaction between your trailer and your tow vehicle.



Dual-Cam Sway Control Turning

During basic, straight-line towing, the cams lock in place and hold the trailer steady by applying constant, consistent pressure to both sides. This keeps the trailer from swaying in crosswinds. When you go into a turn, the cams unlock and slide to allow a controlled, full-radius maneuver. If you swerve suddenly, the cams will give to accommodate the movement while still working to obtain a straight angle, thereby maintaining control of the trailer.

  • Which Weight Distribution Hitch for a 2007 Ford F-150 Towing a 7,000 Pound 31 Foot Travel Trailer
    With length of 31 feet I would highly suggest using a weight distribution system with a Dual-Cam sway control system. Calculating 10-15 percent of the trailer weight gives you an approximate tongue weight range of 700-1,050 pounds. The best fit then for a weight distribution with dual cam sway control would be Reese Trunnion Bar Strait-Line System, part # RP66084. This system is a great fit for your trailer weight and the Dual-Cam Sway control will really help to keep the 31 foot trailer...

  • Recommended Weight Distribution System With Sway Control For 2017 Coleman FQ Trailer
    In looking up your 2017 Coleman FQ online, it appears that your trailer has a dry weight of 3205 and a dry hitch tongue weight of 453. Based on it's length and weight, I think you are wise to consider a weight distribution system with sway control as I believe sway will be an issue and the weight distribution anti-sway systems are far better than the friction bars. With a lightweight trailer with a 21 foot 5 inch length preventing sway is just as important as correcting sway. With a weight...

  • Weight Distribution System on a 2005 Suburban 1500 Did not Completely Level Vehicle and Rides Poorly
    It is possible that the trailer is simply too large for a 1/2 ton SUV. The weight is borderline of what I would be comfortable towing with a 1/2 ton, but the length I think is a bigger concern. That is an awfully long trailer not to be use a 3/4 or 1 ton tow vehicle. We can do some digging and testing to see if we can improve your ride, but I will need some more information from you. 1. What is the towing capacity of the Suburban? See the Vehicle Owner Manual for this info. 2. Is 7,800...

  • Recommended Parts for Towing a Starcraft Antigua Trailer with a 2004 Chevrolet Trailblazer
    The weight distribution you were looking at, part # RP66541, will carry over to a new F-150. You may need to get a different height shank or adjust head angle or spring bar tension, but everything else will be able to be used. Does the owner manual state the vehicle has different capacities with a weight distribution system? Some vehicles have two ratings listed in their owner manual. If the manual states different figures for weight distribution, please write back and let me know. If...

  • Will the Strait-Line Weight Distribution RP66073 Work on an Interstate 20 Super Coach Trailer
    I did some research on your Interstate 20 Super Coach trailer, and found that the trailer has an 8 inch I-Beam frame and most likely an adjustable channel tongue. This is the reason that you are having difficulty with the weight distribution system. It seems to me that if the sway control ball mount is hitting on the left, driver side when turning that the right, passenger side sway control ball mount extension would also be making contact when turning. If this is the case, we do not have...

  • Will the Addition of Weight Distribution Increase Towing Capacity for a 2007 Chevrolet Colorado
    Your salesman is correct in that a weight distribution system will, in most cases, allow a vehicle to tow additional weight, but the amount of additional weight is not a static number and is vehicle specific. You should check your owners manual, or the vehicle dealer, for hitch specifications for the Max Gross trailer weight allowable when using a weight distributing hitch. I checked the online owners manual for a 2007 Chevrolet Colorado. If this is the the vehicle you will be towing...

  • Choosing the Best Weight Distribution System for 2018 Rockwood 2104S Trailer With 6,000 lb GVWR
    In order to determine the correct weight distribution system, you will need to know your total tongue weight (TTW) which is the tongue weight of your loaded Rockwood 2104S plus the weight of any cargo behind the rear axle of your 2014 Ram 1500. Typically, your tongue weight is going to be between 10% and 15%% of your trailer's GVWR, and according to my research, your new 2018 Rockwood 2104S trailer has a GVWR of 6,028 lbs. That would put your TTW in the range of 800 lbs and you would...

  • Recommended Weight Distribution System that Will Not Need to Drill Holes in Trailer Frame to Mount
    If you are worried about drilling into the frame of your aluminum trailer when installing the Reese Strait-Line Weight Distribution System, like # RP66073, then I recommend the Equal-I-Zer Weight Distribution systems. The Equal-I-Zer WD system, like # EQ37060ET, has frame mounts that will mount around the frame instead of drilling bolt holes and bolting the mounts to the aluminum frame. The Equal-I-Zer system uses friction bars to help distribute weight and to control trailer sway. As...

  • Availability of Replacement 22210E Spring Bar on Reese Weight Distribution System
    I was able to share the pictures you attached of your existing Reese WD system with my contact at Reese and she unfortunately said these particular spring bars are no longer in production. They are a bit different in size too than the current models, so there isn't an alternate available that would fit the openings on your current Reese head unit. Because of this your best, and really only, option at this point will be to go with an entirely new system. For the current equivalent in...

  • Flagstaff HW29SC Weight Distribution System Recommendation
    We can definitely help you out with a weight distribution system for your Flagstaff HW29SC! I'm guessing the reason your RV Dealer said a WD can't be used on the trailer is because the top of the tongue where the brackets would mount is a bit crowded with your propane and battery banks. With this being the case I recommend installing the Reese Strait-Line Weight Distribution System w/ Sway Control # RP66073 with the shank # RP54970 and then using the Chain Hangers # RP58305 so the chains...

  • Will Adding Heavier Bumper and Bike Rack with Bikes to Back of Trailer Make Tongue Weight Too Low
    Tongue weight should typically be 10 to 15 percent of the gross trailer weight. Adding what would likely be about 100 pounds to the very back of the trailer wouldn't decrease the tongue weight too much. If you notice that the trailer is more susceptible to sway after installing the new bumper and bike rack/bikes, then it could be because the tongue weight is too light and adding a little weight to better balance it out should take care of the issue. As long as the tongue weight is within...

  • Recommended Weight Distribution System for Keystone Springdale Trailer
    The most important factor to consider when choosing a weight distribution system is the total tongue weight of your towing setup. This will include both the loaded tongue weight of your trailer, along with any added cargo weight coming from behind the rear axle of your Ram truck. This number will ideally fall somewhere around the middle of the system's operating range that you choose.

  • Recommended Weight Distribution/Sway Control for Forest River R-Pod 179 Hood River Edition

We offer a simple-to-use scale # e99044 but other methods for measuring TW are noted in the linked article.

    First, let me just say that the Airstream Bambi has got to be the cutest name for a travel trailer that I have ever heard. Please send some pictures of it if you can! For weight distribution you will need to go by the total tongue weight. This is calculated by taking the tongue weight of the trailer when loaded and ready to tow and then adding the weight of anything loaded behind the rear axle of the tow vehicle. In your situation, if the trailer tongue weight is 350 pounds and you have...

    One of the great features of the Reese Strait-Line Weight Distribution hitch # RP66073 is that when you go into a turn, the cams unlock and slide to allow a controlled, full-radius maneuver. This system also allows you to back up freely without disconnecting the bars from the hitch, so you don't have to worry about having any issues when backing up and turning at the same time.
