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.


Integrated Dependent Sway Control

The Steadi-Flex weight distribution system works to stop trailer sway before it begins. This is achieved in 2 ways. First, the system head is designed to firmly hold the spring bars in place to provide tight resistance and help ensure that your trailer tracks behind your vehicle. Second, the spring bar brackets that mount on your trailer's frame produce friction with the bars whenever any side-to-side motion occurs. This keeps the bars from moving, also helping to hold your trailer in a straight line.


System Head with Steel-on-Steel Friction

System Head

The head of the Steadi-Flex system firmly holds the spring bars in place at the hitch point. This tight hold helps to keep the bars from moving, which in turn helps to ensure that the trailer is held firmly in place behind your vehicle. If any sway or side-to-side movement does occur, the spring bars will move only slightly inside of the system's head. This steel-on-steel contact produces frictional resistance to limit further side-to-side motion of the bars, limiting the motion of your trailer in the process. The Steadi-Flex head is wider than most weight distribution heads. This design allows for greater surface area for the spring bars to move against. This makes it easier to produce the friction that resists sway.


Sway Control Brackets with Automotive-Grade Friction Material

Friction Material Brackets

The spring bars attach to the trailer frame with fixed, sturdy steel brackets. They sit on top of the brackets instead of being suspended by chains like the bars that are on traditional weight distribution systems. Chain suspensions typically allow a good deal of side-to-side play in the system. Because the Steadi-Flex has brackets in place of chains, that unwanted movement of the spring bars is eliminated. This helps to keep your trailer in line behind your vehicle. In addition, these brackets create friction to limit any side-to-side movement that may occur. When each spring bar on the Steadi-Flex system moves within the bracket, it rubs along the surface of the bracket, creating friction. This resistance limits the movement of the spring bar, thus preventing further side-to-side movement of the trailer.


Most systems with sway control brackets use bare steel brackets to create friction with the steel bars. Steel-on-steel friction typically causes a much louder ride, and it can result in wear and tear on the brackets themselves. The Steadi-Flex brackets, on the other hand, are lined with automotive-grade friction material. This material is more abrasive than bare steel, which allows more friction to build up faster and easier. The long-lasting friction material also reduces the banging noise created by the bars hitting the inside of the steel brackets. This provides a quieter ride while towing.


Fast, Easy Installation

The Steadi-Flex system is easy to install and set up. On the trailer side, simply clamp the spring bar brackets around your trailer's frame. Then prepare your vehicle by sliding the included shank into your 2" x 2" hitch receiver, and bolt on the head. The system head can be easily adjusted to achieve the proper angle and optimum leverage for your specific setup. No drilling is required to install this weight distribution system.


Head Tilt Adjustment

The Steadi-Flex system uses the traditional washer-style adjustment method to achieve the perfect tilt. Controlling the head tilt helps you to fine-tune the leverage and maximize the amount of tension in the whole system. To adjust the tilt, simply slide washers onto the adjustment pin and insert the pin into the head assembly. To increase the angle, add a washer. To reduce the angle, remove a washer.


Tapered Spring Bars

Spring Bars

The spring bars of the Steadi-Flex 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 to evenly distribute the weight between your tow vehicle and your trailer.


The bars easily pin into place inside the system head - no need to torque or re-torque any trunnion bolts to adjust the tension. With fewer parts to manage, installing and maintaining the Steadi-Flex is simple.


Adjustable, Clamp-On Brackets

Adjustable Brackets

The spring bar brackets simply clamp around your trailer's frame - no drilling required. These brackets are designed to be positioned 27" to 32" back from your coupler and they can fit a wide range of frame sizes and can even be used on a trailer with a bottom-mounted coupler.


While other brackets use relatively thin L-pins to secure the spring bars in place on the brackets, the Steadi-Flex system uses steel pieces that are almost as wide as the brackets themselves to secure the bars. These retention brackets easily pin into place once wrapped around the spring bars. As a result, you can have greater piece of mind knowing that the spring bars are secure and less likely to rattle around inside of the brackets.

Video Transcript for Reese Light Duty Weight Distribution System Review

Today, we're going to be taking a look a the Reese Light Duty Distribution System with sway control. With a six thousand pound gross trailer weight, in a six hundred pound tongue weight, part number RP66558. It's also available in a four thousand pound gross trailer weight and a four hundred pound tongue weight, part number 66557. You've decided you need a weight distribution system. The Reese Light Duty Weight Distribution System is perfect for an SUV and a small travel trailer set up as you see here. The sway control is going to help reduce the movement caused by wind, curving roads or sudden maneuvers. As with all weight distribution systems, it going to evenly distribute weight over both the tow vehicle and the trailer's axles.

This is going to provide a safer, more stable ride with less tire wear, better braking and handling. The spring bar hangers have integrated friction pads to help prevent sway. The hangers themselves do not take up very much space, making it perfect for smaller size trailers. It's a no drill installation with all the hardware provided. The kit even comes with weight distribution shank that you hook up with your own hitch ball.Speaker 2: As you can see with our hook up crosstalk 00:01:04 here at the rear.

crosstalk 00:01:10 raised up about an inch.crosstalk 00:01:06 In hitch ball, those require one inch diameter shank. The spring bars will flex appropriately over uneven terrain for a more controlled ride. The whole thing is coated in a black powdered coat so it's going to be corrosion resistant and it's going to stand up to the elements. Now that we've gone over some features, I'll go ahead and show how we got it set up. First thing we'll want to do is take some measurements on our vehicle.

From the ground up to underneath our wheel well, we've got 36 inches. We'll want to write that down. In the front, we've got 34-1/2 inches. These are the measurements we want to get back to when we engage our weight distribution system. For comparison, we're going to hook up our trailer without weight distribution and take those same measurements. As you can see with our trailer hooked up without weight distribution, here at the rear, we're squatting about 2-1/2, 3 inches and here at the front, we're raised up about an inch.

You can see the problem that we're having. The front of our vehicle is tilting upward. We'll want to take note of those measurements that way we have something to compare it to when we get our weight distribution hooked up. Then, when we re-engage our weight distribution and get it hooked back up, we're within a 1/4 to a 1/2 inch of our stock measurement. That's where we want to be. Now, if the front wheel height is higher than previously measured, the head tilt angle must be increased. That's tilted downward. If the front wheel well height is substantially lower than originally measured, an inch or more, the head tilt angle must be reduced. That's tilted upward. The next thing you want to do is make sure your trailer is level. The easiest way to do that is to raise or lower your tongue jack so that you have the same measurement in the front and in the back. We've got it. Keep in mind when setting up your weight distribution system, you need to make sure that your trailer is fully loaded and ready to go. The next thing we'll do is take a coupler height measurement. the reason we're going to do this is it's going to help us determine the correct ball height. We've got 22. We'll need to take note of that. We've gone ahead and swapped out our old ball mount with our new weight distribution shank. We've previously adjusted our ball height. I'll go ahead and show you how we did that. First, we got close to the desired height by selecting a mounting location for our bolts. First, to help us set the tilt of our head, we installed several of the included washers as spacers. The number of washers you will use will vary depending on your set up. Then to get the approximate height of your ball, you'll want to install your shank in the rise or drop position and then choose the desired location to put in your bolts. With the approximate ball height set and loosely installed, lets go ahead and line up our coupler with the ball. Now, with our ball attached to our coupler and our trailer back to level we can bring in our spring bars to help us determine the location of our frame brackets. We'll bring it in. You'll need to grab the pin and the clip. We're going to insert it between the head there. Drop the pin in when it's lined up and put the clip in on the bottom. Here's where it gets tricky. You want to be sure that your brackets are between 25 and 32 inches from the center of your coupler and you want to make sure that there's nothing interfering like your propane tanks or your battery box. You also need to position them so that your spring bar extends at least 3 inches beyond the bracket. With our bracket location determined, we can go ahead and install it. We'll then install our L-bracket and leave it loosely installed. We can repeat that same process for the other side. With our bracket torqued down and our L-bracket loosely installed, we'll need to be sure that our spring bar is 4 inches from the bottom of our L-bracket. That's for the six hundred pound system which is what we have here. For the four hundred pound system, it needs to be 3 inches from the bottom of the L-bracket. Now, if for some reason that didn't work out, you'll need come back to the tilt of your head and add or subtract washers. If you run out of washers, you may need to adjust the height of your L-bracket. The next thing we need to do is lock in the tilt of our head by torquing it down to the manufacturer's specifications. Now, we're ready to take our included tool and put our spring bars into place on the L-bracket. To make it easier, we can raise our tongue jack. How the tool works is it goes underneath the spring bar and hooks into the L-bracket. You want to stand off to the side to avoid injury. Because we left our L-brackets loosely installed, they have adjusted to accommodate our spring bars. Now, we can install a tension bracket to keep our spring bar in place. With that in place, we can now torque down our L-bracket bolts. With everything installed, let's go ahead and lower our jack. Once you get to your destination, in order to disconnect, you want to raise your tongue jack all the way up and this is going to make it easier to safely remove your spring bars. We can go ahead and remove our tension bracket. Now, we can just remove the spring bar from the L-bracket. We'll just repeat the same process on the other side. With our spring bars disengaged, we can go ahead and take them off. Now, we can just lower it back down, uncouple it and we've got it. That's going to complete our look at the Reese Light Duty Weight Distribution System with sway control at six thousand pounds gross trailer weight and six hundred pounds tongue weight, part number RP66558.

Working well for my Boat Trailer with surge brakes. I'm happy I went with this 600/6000 LBS version instead of maxing out the 400/4000 LBS version on my 380/3700 LBS rig. I'm now towing legal again since down-sizing my tow vehicle to a 2015 Ford Flex, AWD, V6 EcoBoost, Even with the factory tow package the Flex is only rated for 200/2000 without WDS, but 450/4500 with WDS. I did a couple trips to my local lake before WDS (30 mile round trip via 45 MPH roads) and the Flex felt safe for that distance/speed, but it had a lot more trailer jolt and was not quite as stable as my old GMC Envoy XL. The WDS has improved the towing stability and ride well beyond my expectations, and is now even better then towing was with buddy's full-size Pickup. I did have to use a Pole-Tongue Adapter (RP58393), and customize the adapter mounting to my trailer, but I can already tell this added hassle and expense will be well worth it for the long-haul trips I do a few times a year. 228117

Was used to tow a 3500lb. travel trailer with YJ Jeep with a 5.3ls engine conversion. Set bars to a very light setting. Trailer tows very nicely. Great product. The braking system for anti-sway is one of best on the market. Replaceable brake pads are the way to go, just like in tow vehicle. 666976

I just bought a new trailer that is 7 feet longer than my last and heavier and I now have a truck instead of an SUV so I needed to get a new weight distribution hinge with sway control. etrailer had all the best brands at the best price and delivery was fast. Unfortunately that's all I can comment on so far. I'm not picking up the new trailer till mid April, so I can't comment on how well it works or show pictures. I'll update later. 616797

I've towed a few thousand miles with this hitch on my Astro Van (properly equipped) pulling a 15ft open deck car trailer(~4000lb loaded with 450lb TW). I have been very happy with this purchase. The anti-sway system on the WDH works very well even with my smallish tow vehicle. No issues when towing in crummy weather with strong winds and driving rain, the hitch handled wonderfully. The sway control is fairly quiet when making sharp turns or backing up. Great product! 502392

Excellent customer service and helpful installation video online. I was disappointed in the quality of the product (not etrailer's fault) due to poorly tapped holes and paint in the holes that made assembly slightly more difficult than should have been required. Just be aware of this so you don't cross thread any bolts and strip out the threads! 497723

Hitch works great. Sometimes use it without sway bars (for short trips), but noticeably less sway and bobbing with sway bars attached. Used with Ram 1500 and Lance 1995 trailer.

Very heavy duty. Well made and easy to assemble. It “groans” a bit in tight turns until you shoot the trunnion bars with lube at the hutch end. Otherwise a really nice piece of equipment for the price. Does a terrific job stopping bounce and sway. 638561

Review from a similar Steadi-Flex in Weight Distribution Hitch


When I upgraded my trailer, I was told the Pro-Series #800 hitch, with a separate sway control would be fine. I apparently don't set the sway control tightness the same everytime, so I experienced various levels of sway and bouncing with that hitch. So, I did some research and I bought the Reese Steadi-Flex 1000# w 6 point sway control. It was a night and day difference. No more anxious moments and my confidence even grew when the trailer behaved in gusty cross-winds and when the big trucks would pass. I had to do some running around to complete the assembly, since I didn't have all of the right sized tools; But, so happy with the results. 688166

Usually the tongue weight of your trailer is 10-15% of it's total weight. I've attached an article to help you determine this. For your combination,...

  • Recommended W/D System for Fleetwood Bayside Pop-Up Towed By 2009 Dodge Dakota
    You would choose a system based on the fully loaded and ready to tow tongue weight of your pop-up. You should also include the weight of anything carried in your truck bed behind the rear truck axle. According to my research, the dry weight (empty propane and water tanks) of a 2005 Fleetwood Bayside is around 2600 lbs. A full water tank would add about 220 lbs, and two full propane tanks add around 80 lbs (tanks are around 20 lbs each empty, 40 lbs each when full). This adds up to around...

  • Recommended Weight Distribution System for Prowler Lynx Trailer with 360 Pounds of Tongue Weight
    If the 360 pounds of tongue weight is with the trailer loaded and ready to tow then I suggest the Reese Steadi-Flex # RP66558. It's rated from 400 to 600 pounds tongue weight and you'll fall right in the middle. The Steadi-Flex uses automotive style friction pads for sway control and doesn't use chains. You'll need a hitch ball with a 1 inch shank. Use # 63845 for a 2 inch ball or # 63847 for a 2-5/16 inch ball. If your trailer will be heavier when you're towing it and you need a...

  • Is a Weight Distribution Needed to Tow a 2015 Forest River Wolf Pup 16BHS by a 2013 Toyota 4Runner
    When a trailer weighs more than 50 percent of the tow vehicle's weight, we recommend using a weight distribution system. Also, sway control is a good idea, especially when towing with a midsize SUV. To choose a weight distribution system you will need to go by the total tongue weight of the towing set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle. Keep...

  • Will Reese Steadi-Flex Weight Distribution System Fit a Casita Travel Trailer with C-Channel Frame
    Based on your picture the Reese Steadi-Flex system # RP66558 would have to have the frame brackets mounted at the 32 inch location because the propane bottle/brackets are in the way for the rest of the system's range. The propane tank holder would then not be in the way. The frame will need to be boxed to use this system (or basically any system). To do that have a professional welder weld on steel plates in the area the brackets need to go. This system does not include a ball so...

  • Weight Distribution for Towing Spree Escape Travel Trailer w/ 2004 Jeep Grand Cherokee
    The Reese Steadi-Flex Weight Distribution System you mentioned, part # RP66558 is designed for trailers whose tongue weights range from 400-600 lbs. As long as the fully loaded and ready to tow tongue weight PLUS the weight of anything stowed behind the rear axle of your GC in the cargo area isn't more than 600 lbs, this system would be an excellent choice to provide weight distribution as well as trailer sway control. I'll link you to an article that will show you how to determine the...

  • Recommended Weight Distribution/ Sway Control System for Towing 2016 Forest River Wolf Pup 16BHS
    To choose a weight distribution system, you'll need to first determine the fully loaded and ready to tow tongue weight of your trailer. To that figure, add the weight of any gear stowed in the cargo area of the tow vehicle behind the rear axle. I've linked to an FAQ article that explains how to do this. These combined figures represent the Total Tongue Weight (TTW) of your set-up. The TTW of your trailer should fall as close as possible to the middle of the effective range of the weight...

  • Recommended Weight Distribution System for 2014 Ford Flex Towing a 3,200 Pound Camper Trailer
    I suggest a weight distribution system that has sway control. To choose the correct system you'll need the tongue weight of your loaded and ready to tow trailer added to the amount of gear in the Ford Flex behind its rear axle. A trailer's tongue weight should fall within about 10 to 15 percent of its total weight. The best way to determine your trailer's tongue weight is to use a scale # 5780 Since your trailer is 3,200 pounds empty and it's presumable that you will be adding to...

  • Weight Distribution/Sway Control for a Ford Expedition and Keystone Springdale 189FL Travel Trailer
    The length of the trailer should not be an issue for you so I would not worry about that. Anytime the trailer weighs at least 50 percent of the towing vehicle when loaded and ready to tow using weight distribution is a good idea and the use of sway control will be beneficial as well. Big trucks passing or a cross wind on a highway can cause sway so it is better to be prepared for the inevitable rather than wishing you had sway control. There are a couple of weighs you can determine the...

  • Recommended Weight Distribution System for 2016 Flagstaff 425D Travel Trailer
    When looking for a weight distribution system you want to take the loaded tongue weight as well as any cargo behind the rear axle and have that total tongue weight ideally fall in the middle of the range for the WD system. My recommendation for your weight distribution system is the Reese Steadi-Flex Weight Distribution System w/ Sway Control - Trunnion # RP66558. This system uses friction material similar to automotive brake pads to assist with controlling trailer sway. Then you...

  • Recommendation of Weight Distribution System for 4500 lb Boat /Trailer With Surge Coupler
    Using a standard weight distribution system that utilizes the snap up brackets and chains is not a good idea on trailers with surge couplers. The tension on the chains would interfere with the operation of the coupler. I recommend the Reese Steadi-Flex Weight Distribution System, part # RP66558. This system features integrated sway control. The spring bar brackets clamp onto the trailer frame, and would not require you to drill any holes in the frame. This system is designed for trailers...

  • Choosing Weight Distribution System for Trailer with 400-550 lb Tongue Weight
    Using spring bars with a capacity that is much higher than your trailer tongue weight would lead to an excessively rough ride. Because the spring bars would be extremely stiff, the system would not be able to transfer much weight to the front vehicle axle, which is the whole purpose of the system. When you are determining which system to choose, you want to consider the fully loaded and ready to tow trailer tongue weight plus the weight of anything stowed behind the rear axle of the...

  • 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...

  • Is Weight Distribution Needed to Tow 6 x 10 Enclosed Tandem Axle Trailer w/ 7000 lb GVWR
    Anytime the weight of the trailer exceeds half the weight of its tow vehicle, using weight distribution is recommended. If you'll be towing frequently on the highway, the large cross section of the side of the trailer will make it susceptible to trailer sway caused by crosswinds and turbulence caused by passing and oncoming traffic. Because of this, I'd recommend you use the properly rated weight distribution system that provides a sway control component. To choose a weight distribution...

  • Weight Distribution with Sway Control for Jayco Swift 154bh and 2003 GMC Yukon XL
    Moving the suspension to the top of the axles will make the trailer more susceptible to sway. If you needed more height to tow the trailer level the best method is to use a ball mount with the right amount of drop. The same would go for weight distribution. To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything...

  • Weight Distribution for a 2010 Chevy Silverado Towing a 5,100 Pound Travel Trailer
    That 350 pound tongue weight is likely the dry tongue weight. If the gross trailer weight is 5,100 pounds when loaded and ready to tow then the tongue weight would be 510 to 765 pounds (10 to 15 percent of he gross trailer weight). Then to that you would add the weight of anything carried in the bed behind the rear axle of the 2010 Chevy Silverado. The Fastway e2 system # FA94-00-0800 is rated for 400 to 800 pounds tongue weight so it covers the range above. You would also need ball...

    Given the weight of the travel trailer and the tongue weights you mentioned, I recommend the Reese Steadi-Flex Weight Distribution System, part # RP66558.

You will want to find your total tongue weight (see linked FAQ article) and make sure the tongue weight falls within...

  • Do Adjustments Need to be Made to Weight Distribution System if Truck Rides Too High in the Front
    If you are using a weight distribution system like the Reese Steadi-Flex, part # RP66558, and the front end of your truck is too high, it sounds like you may be using a system that isn't rated high enough for the tongue weight of your trailer. I recommend that you start by determining the tongue weight of your trailer (I am including an article on this) and compare this to the weight rating of the system. If the tongue weight exceeds the rating, I would try removing some of your cargo...

The # CC-275 will attach to the a-frame of your trailer up near the coupler and then would allow you to carry a bike rack in the hitch opening. I attached a review video for this rack for you to check out as well. The most popular bike rack we carry that has been confirmed to fit this vehicle is the Thule Roadway 2 part # TH912XTR.

    The first step in choosing a weight distribution system is to conclusively determine the tongue weight of your camper once it is fully loaded and ready to tow. This includes full water and propane tanks plus any other gear you would typically travel with. The weight of anything carried in your truck bed behind the rear axle also needs to be considered as tongue weight. I have linked you to an article that describes how to determine your tongue weight.

    The key to choosing the correct weight distribution system is knowing the tongue weight of your trailer when it is fully loaded and ready to tow. Keep in mind that anything loaded behind the rear axle of your 2010 Jeep Liberty will contribute to the tongue weight as well. I would recommend choosing a system that has a tongue weight capacity range that encompasses the tongue weight of your trailer with its heaviest load. We know that the tongue weight of your trailer must stay under...

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.
