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.

  • Trying To Find Weight Distribution Hitch For Tent Trailer With A Crowded A-Frame
    Hello Andrew, thanks for reaching out. There is not a lot of room to spare on your trailers tongue. In fact, you would almost certainly have to relocate your battery box and some of your wiring in order to install most weight distribution hitches. There is one different attachment method that would make things easier, and that is to use bolt-on chain hangers from Reese. I suggest that you use the Strait-Line Weight Distribution w/ Sway Control # RP66072. This is made for trailers with...

  • Recommendation for WD/Sway Control for 2007 Fleetwood Saratoga and 2010 Ford Flex
    Tongue weight will depend on how you load it. I would check the Flex owners manual to see what the weight distribution capacity of the vehicle is. Some vehicles cannot use weight distribution systems. I am not sure on the Flex, but to be safe, I would strongly recommend checking the owners manual. Some of the aftermarket hitches we have do allow use of weight distribution system and some do not. The ones that do, do not allow an increase in tow capacity. So I would imagine if your factory...

    The best aftermarket brake controller you can buy is the Tekonsha Prodigy P3 Trailer Brake Controller item # 90195 which will outperform the factory brake controller tenfold. The Tekonsha Prodigy P3 is extremely reliable and even if something were to happen not necessarily to the brake controller, it has diagnostic checks to help you find out what the issue is and safeguards to protect your vehicle, trailer and the controller if it were anything serious. The other reason that people like...

  • Best Weight Distribution and Sway Control for 2009 Jayco Jay Feather Ex-Port
    The best option for sway control and weight distribution for your 2009 Jayco Jay Feather 17C that has a tongue weight of 400 lbs is the Reese Strait Line part # RP66082 which has a tongue weight range of 200-600 lbs and features the best sway control at fighting to prevent sway from starting. For a hitch ball then you'd want the # A-90 and you'd be set.

  • Recommended Weight Distribution System for a 3,500 lbs Airstream Trailer
    I understand your concerns and I'll be happy to help you. You have a lot of truck and not much camper. From what I can find it looks like a 16' Airstream trailer tops out around 3,500 lbs. The Gen-Y Torsion 2-Ball Mount item # 325-GH-1324 you were looking at will do a great job of absorbing road shock and bounce but it will not address sway in any way. Since you're worried about sway, I recommend adding a weight distribution system to your set up. This would keep your trailer in line...

    Typically, we figure trailer tongue weight as being from 10 to 15 percent of the weight of the fully loaded trailer. You have provided me with the weight of the items placed on the trailer, but not the weight of the trailer itself. When figuring tongue weight, the weight of any items placed behind the rear axle in the tow vehicle must be considered as well. We have an online page that shows how to determine the tongue weight of the trailer using a length of pipe, some scrap lumber and...

    Yes, the Strait-Line Weight Distribution Hitch System can be adapted to a V-Nose style trailer. You would need to use an alternate mounting system for the chain hanger brackets.

    We no longer carry Husky weight distribution systems, so unfortunately we wouldn't have any replacement parts.

The weight distribution head offers the holes for mounting a sway control bar like part # 83660. It's recommended that two sway units be used on trailers 26 feet in length or longer. The # RP66022 doesn't include a shank, but you...

The Tow-Pro Elite is very similar in design to a factory trailer brake controller.

  • Recommended Weight Distribution Hitch for a 4,000 Pound Trailer and a 2003 Honda Pilot
    To be on the safe side, we will assume the maximums; trailer weight of 4,000 pounds and tongue weight of 425 pounds. When selecting a weight distribution system, the most important thing is properly matching tongue weights. That being said, you never want to exceed the gross trailer weight capacity either. We have a few weight distribution systems with sway control, that have a 400-600 pound tongue weight range and they all have more than enough gross trailer weight capacity. Being that...

  • Weight Distribution for a 2008 Dodge Durango
    For your 2008 Dodge Durango I would recommend the Reese Strait-Line Hitch 200 to 600 pounds tongue weight / 12,000 pound gross trailer weight # 66072. With this system there are no U-bolts to conflict with bottle racks or other A-frame mounted items so it should work with your tanks and battery. To make sure this system will work you need to be sure the tongue weight, when loaded and ready to travel, does not exceed 600 pounds or that the gross trailer weight does not exceed 10,000 pounds.

  • How to Select Correct Weight Distribution System for Rockwood Toy Hauler Tent Trailer
    The key to selecting a weight distribution/sway control system (WD/SC) is knowing the actual tongue weight (TW) of the loaded trailer and to this figure adding the weight of anything in the tow vehicle that sits behind the rear axle, such as a generator or cooler. This cargo will act just like trailer TW and so it needs to be accounted for. We offer a TW scale # e99044 to simplify measuring. Ideally this total TW falls right near the middle of the operating range for the chosen WD/SC system....
