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.

Friction Material

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

System Head

The head of the Steadi-Flex can be easily adjusted for the best possible angle for your towing setup. Adjusting the head lets you fine-tune the system's leverage so that you can get the best distribution of weight possible. Traditional head tilt adjustment methods require that the head be disassembled so that stackable washers inside the head can be either removed or added on. But with the Steadi-Flex, there are external, toothed washers on either side of the head that make it easy to change the tilt. Simply position the head in one of the preset angles based on your hitch's tongue weight, then bolt it in place, tightening the washers as you do so. Once the head is sitting at the correct angle, tighten the internal adjustment bolt to secure the platform in place.

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

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.

Adjustable Brackets

While other brackets use L-pins to secure the spring bars in place on the brackets, the hinged Steadi-Flex brackets close completely around the spring bars. As a result, you can have greater piece of mind knowing that the spring bars are secure, all without the hassle of using and possibly losing L-pins and any extra hardware.

Video Transcript for Reese Weight Distribution - WD With Sway Control - RP66561 Review

Today we're going to be taking a look at the Reese Steady Flex Weight Distribution System with built in sway control. This is an all-in-1 sway control and weight distribution system that's going to evenly distribute weight over the axles of the tow vehicle and trailer, which is going to offer better stability and better control. Ultimately, this unit's going to create a more level ride for both the tow vehicle and your trailer. This weight distribution system has a tongue weight capacity of 1,400 pounds and a gross towing weight of 14,000 pounds. It can be used with top mount and bottom mount trailer couplers, as well as trailers that have surge, or hydraulic brakes. It does not have to be taken off when backing up your trailer. Just make sure to avoid sharp turns and jackknife situations. 1 of the most unique features about this weight distribution system is the built in sway control.

It's going to use friction style sway control. It's going to have 6 point sway control. When it comes to those different points, we're going to have 1 point here at the end of each bar on this side, 1 on this side, and then we're going to have a total of 4 here in the head assembly, 2 on top, 2 on bottom. These brackets are designed to keep the spring bars in place for a nice, rigid system. That's going to hold your trailer in line. The unit does not use lift chains, so it eliminates unwanted movement of the spring bars.

If we undo this portion right here, you can see that the bars are going to sit on these nice, thick friction pads. These are going to be automotive grade friction material in the brackets that help correct sway that may occur due to the winds, curvy roads, or sudden maneuvers. It's a really nice design of the unit. We're going to have those friction pads located on each side. Here at the head assembly, the system head is going to provide frictional resistance to limit movement of the spring bars as well. 2 points of sway, here at the brackets, 1 on each side and then 4 points of sway control on the head assembly, 2 on top, 2 on bottom. The steel spring bars are hot rolled and tapered for superior strength and flexibility.

These bars will flex appropriately over uneven terrain, which is going to offer a nice, controlled, even ride. This design allows for maximum ground clearance as well. You can see that we have a nice low profile design here at the head assembly. Just with the steady flex bars and the brackets, we're looking at maximum amount of ground clearance possible. When it comes to tilting the head assembly, that's easily achieved. It's going to use an elongated, serrated washer design.

Here, on these washers, I'm going to flip this around. Actually, I'm going to scoot it up and then I'm going to bring you just closer in on the head assembly. This unit's going to use an elongated washer, that's this portion right here. Then, there's going to be teeth on 1 side and there's teeth in the head assembly. Those grooves are going to line up. That's going to allow you to adjust the tilt, or the pitch of the head assembly. This design allows for quick and easy adjustment of the head assembly, which is going to increase, or decrease tension on your spring bars. Adjustment of the head assembly is very important in weight distribution systems. This design simply makes those fine tune adjustments very simple, which is going to help ensure a safer more enjoyable towing situation. There's going to be that elongated washer on each side here on that top connection point. There's also an adjustment bolt inside the head assembly. You have your hitch ball hole right here. Go straight back. Right here is an adjustment bolt. What you can do is once you have the desired tilt achieved for your situation, you can simply rotate that bolt until it makes contact with the front face here of the adjustable shank of the unit. Sometimes that might be difficult to do. What you can do is you can simply just take a flat blade screwdriver. It's got ridges on that bolt. You can just push it in and then rotate it over until it makes nice firm contact with the front face of that shank. These brackets right here, these are no drill clamp on brackets that can adjust along the trailer frame to accommodate frame mounted items such as battery boxes, gas tanks, tool boxes, or generators. The brackets are going to be positioned between 27 inches to 32 inches from the center of the trailer cup, or from the center of the hitch ball that's being used on the system. These brackets are going to attach to the trailer frame. This piece goes on the inside of the trailer frame. This piece goes on the outside of the trailer frame. You attach this to your trailer frame. When you're ready to set up your system, you slide this portion right here over this bar. It's got the grooves that line up. Then you can adjust it however you need to for your particular situation. It comes with all necessary hardware to get everything installed and fully assembled, installed, and tighten down. That way you're set and ready to go. Really nice design. I also want to mention that it's going to come with the adjustable shank. That's going to be this portion right here. This slides into the trailer hitch receiver on your vehicle and then it provides the attachment point for the head assembly. The adjustable shank is going to give the unit plenty of adjustability. This can be used in either the drop or rise positions. It's going to offer 7 vertical mounting holes. Those holes are going to be separated on center by an inch and a quarter. The maximum rise that you can get with this unit's going to be 7 inches. That's measuring with the system straight and squared off, so no tilt. If you have this in the rise position with the head assembly at the highest setting, it's going to give you a maximum rise of 7 inches. That's from the inside top edge of the receiver tube of your hitch to the top of the ball platform. With it in the drop position, with the head assembly at the lowest setting, it's going to give you a maximum drop of around 2 1/4 inches doing those same measurements. One of the other neat things about the unit is that Reese designed the system so that it does not need constant adjustment like other weight distribution systems. Once you have everything tightened and installed properly, you'll be set to go for a long time. The unit's going to feature steel construction. It's going to have a really nice corrosion resistant powder coated finish over the entire unit. Your hitch ball is sold separately. This does require a hitch ball with a inch and a quarter diameter shank. If you're in need of a weight distribution hitch ball, you can find those right here at It does come with all your necessary hardware for installation. It's also going to come with these shims right here. These can be used to insure a tight fight between the head assembly and the adjustable shank of the unit. It can slide down right there. It's got the holes for the mounting hardware to still pass through. That's going to allow for some more stability, or a tighter fit right there. This is going to also come with the lift handle. This is going to ease installation by reducing the amount of lifting required by the trailer jack. This simply has a groove and it just helps get the spring bars up into the brackets. This is designed to fit an 2 inch by 2 inch trailer hitch receiver that's rated for use with weight distribution systems. It's going to fit trailer frame heights because of the brackets. It's going to fit trailer frame heights anywhere from 4 inches tall to 7 inches tall. It's going to fit trailer frame widths from a inch and a half to 2 inches. The distance from the center of the hitch pin hole right here on the shank to the center of the ball hole is going to be around 13 1/2 inches when the unit is square and straight. Reese also covers the unit with a limited lifetime warranty. That's going to do it for today's look at the Reese Steady Flex Weight Distribution System with the built in sway control.

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

I have always towed my trailers with my Ram 2500 on just the ball hitch, recently we decided to take a trip that involved a lot of highway travel and I thought I might like to have some sway control. After comparing many different types of sway controls I found this to be the most simple and efficient. We traveled several thousand miles with out any sway problems at speeds up to 80 mph. This product works exceptionally well and was very easy to install and store. I had no trouble with tight turns or backing up. I would recommend this hitch for anyone who intends to tow a large trailer on a major highway next to large trucks. Awesome hitch, you won't be disappointed. 542540

I purchased a Reese Load Distribution Hitch #RP665161 from etrailer. The hitch was delivered as promised within a week. I have assembled the unit in my garage and will install it next week when my 29 ft. toy hauler trailer arrives. It appears to be very well made and very sturdy as advertised. It arrived with all the parts and pieces in good condition and the price was very fair. I will write another review after installation as to how well this hitch performs. I am very satisfied with etrailer and their service. Paul P. 440196

I got this particular Load Distributing / anti sway hitch for my 2016 Jayco Octane 222 toyhauler because it was one that would fit on the tongue with the rack. This Year of the 222 has a large rack behind the propane tanks that holds a generator and 2 batteries. This makes the space avail for the brackets that fit on the trailer frame / tongue a bit small/narrow, and the distance from the ball to these brackets is not very adjustable. I think it was about 27 inches. This Hitch has worked FANTASTIC. The drop shaft is VERY adjustable, and the ball angle is VERY adjustable. Trailer pulls fantastic no issues with sway. The Jayco Octane 222 is not a terribly large trailer, but even in windy conditions minimal mvt from the trailer. The one downside is the shank and ball portion of the hitch are heavy. The sway/load dist bars come of easily with a pin, so it makes moving the hitch easier, but she's got some mass. I would recommend this hitch, and I think if we ever sell our current trailer, I'll keep this hitch for the next one. 452149

I can't review the actual use yet since I do not have the trailer yet, however I can review the purchase and delivery. I purchased on a wed evening, needing it for a Monday pickup of my trailer. The standard free delivery stated Monday before 8pm and I was afraid that would be too late, so I paid for 3 day knowing I could at least intercept at UPS and pickup at UPS location. UPS delivered on Saturday so no need. The box was extremely beat up with one flap open. I was afraid a part might have slipped out. I just inventoried every part against the packing list and all is there, The box is extremely heavy weighing about 90 lbs. I took pictures of the box and contents in case I had to claim a missing part but all looks good. If I can edit this review after I pick up my trailer, I will. I am giving 5 star for etrailer shipping and UPS delivery, As a former UPSer I know a box this heavy is bound to be beat up. The packing was really not sufficient to keep the integrity of the box. the contents slipped around loose, I believe that is the manufacturer's lack of proper packing and nothing with etrailer. 544606

The hitch works great the only downfall is the break pads come loose from there mounts. 513324

I am pulling a 35 foot travel trailer with a Ford F250 diesel single rear wheels. I like it. I usually drive about 65 mph. Most of the time I don't even feel the 18 wheelers. Once I got it adjusted it is easy to hook up. I had a good experience dealing with the people at etrailer. So I am a happy camper. 708208

Do you have a question about this Weight Distribution?

  • 2005 Ford Excursion Squats when Using Husky Weight Distribution with 9,000 Pound Trailer
  • Let's first look at the numbers. A trailer weighing 9,000 pounds will have a tongue weight in the neighborhood of 900 to 1,350 pounds. But when you calculate tongue weight for weight distribution you also have to factory in the weight of any cargo loaded behind the rear axle of your 2005 Ford Excursion. So for example if your trailer's tongue weight is 1,100 pounds and you have 200 pounds of cargo behind the rear axle of the Excursion the total tongue weight would be 1,300 pounds and...

You are going to need a shank that can do much more drop. First you will need to determine how much drop you will need though. To do that check out the help article I attached on the subject. If you need a drop near 8-3/4 inches you would want the Curt Shank part # C17124, or for more around 5-5/8 inches part # 17120.

  • Weight Distribution System Recommendation for 9,500 Pound Pole-Tongue Boat Trailer
  • For your pole-tongue boat trailer, I recommend the Reese Steadi-Flex Weight Distribution with Sway Control # RP66561. To fit this weight distribution system to your trailer, you will want the Reese Pole-Tongue Adapter for Weight Distribution Systems # RP58393. The Reese system uses spring-bar hangers with integrated friction pads to help reduce trailer sway. The trunnion bars help distribute the load of the trailer while providing better ground clearance than more traditional-style round...

  • Comparing Reese Steadi-Flex to Equal-i-zer Weight Distribution System
  • When comparing weight distribution systems, you want to look at the total tongue weight range on each system. The total tongue weight consists of the trailer tongue weight when completely loaded and ready to go and then you also add any cargo behind the rear axle of the tow vehicle. Ideally you want your total tongue weight to be as close to the middle of that range as possible. The Reese Steadi-Flex Weight Distribution System w/ Sway Control # RP66560 has a total tongue weight range...

  • Can a Different Shank be Used with Reese Steadi-Flex Weight Distribution System
  • You do not need to use the specific shank that is included with the Reese Steadi-Flex Weight Distribution System w/ Sway Control # RP66561 referenced in your question. Many weight distribution shanks will be interchangeable with the Reese system. You will just want to match the vertical groove style of the included shank such as with the Reese # RP54998. I have attached a link that will take you to our available selection of weight distribution shanks as well as an article that will...

  • Will Weight Distribution and Sway Control Help a 2007 Toyota Sequoia tow 3100 lb Boat Trailer
  • Anytime your overall trailer weight is more than 50 percent of the total capacity of the tow vehicle weight distribution is recommended. Since your boat empty is close to that I would imagine that you would benefit using weight distribution. When picking out a weight distribution system the most important factor to consider is the loaded tongue weight of the setup. Check out the FAQ article I attached that shows how to determine this. It is very important that you determine this when...

  • Will the Reese Steadi-Flex System Fit a Jayco Eagle HT 272RBO With Top Mounted Coupler
  • Yes, the Reese Steadi-Flex Weight Distribution System part # RP66561 can be returned if there is an issue with your top mounted coupler but you would be responsible for return shipping. That said, we have had several customers use the Reese Steadi-Flex on a Jayco trailer with top mounted coupler so we can confirm you will not have clearance issues. If you take a look at the attached review you will see a customer who uses this very same system on a 2016 Jayco Octane Super Lite which has...

  • Recommended Light Weight and Easy to Use Weight Distribution System
  • To determine the correct weight distribution system for your trailer you'll need to find its loaded and ready to tow tongue weight. Add that to the amount of weight you'll add behind the rear axle of your F-150 and you'll have the total tongue weight of your setup. You want that number to fall within the range of the system you choose. From my research the Dutchmen Aspen Trail's maximum weight is a little under 10,000 pounds which means the tongue weight is likely between 1,000 to...

  • Is There a Reese Weight Distribution System That is Compatible with Surge Brakes on a Boat Trailer
  • There are weight distribution systems available that are compatible with trailers that have surge brakes. When selecting a weight distribution system, you want one that will want to match the Gross Tongue Weight (GTW) of the trailer to the tongue weight capacity of the weight distribution system you choose. The tongue weight of the trailer should be weighed when it is fully loaded and ready to tow. If your trailer tongue weight is 1000 lbs or higher with the boat fully loaded and ready...

  • What is the Best Type of Weight Distribution System with Sway Control
  • The best weight distribution systems with sway control that we offer are the Reese Strait-Line systems, such as the # RP66084 that you referenced. The Strait-Line weight distribution systems use the dual cam type of sway control which is a proactive style of sway control that keeps the trailer inline with the tow vehicle at all times to prevent sway from starting in the first place, rather than trying to correct it once it starts. The other types of weight distributions such as the...

  • Would Reese Steadi-Flex Weight Distribution System RP66560 Work With 960 lb Tongue Weight Trailer
  • Yes, if your tongue weight is 960 lbs dry the Reese Steadi-Flex System part # RP66560 would be perfect for you as it has a tongue weight range of 800-1,200 lbs and your tongue weight falls right in the middle of that which is ideal when picking out a WD system. If your loaded tongue weight exceeds that then you may need a higher rated system. Keep in mind the weight of any cargo behind the rear axle counts as tongue weight as well. The part # RP66561 would be for 800-1,400 lbs tongue...

  • Weight Distribution and Sway Control Recommendations for a 7,500 Pound Enclosed Trailer
  • If given the choice between friction sway control and dual-cam sway control, I will always go with dual-cam. Dual-cam is preferred because it stops trailer sway before it starts. Friction sway control works to stop sway after the trailer has already started swaying. Friction sway control will work, but dual-cam is a pro-active system keeps sway from even starting. When choosing a weight distribution system, you will want one that has a tongue weight capacity range that encompasses your...

  • Lubrication Requirements for Reese Steadi-Flex Weight Distribution System
  • The Reese Steadi-Flex Weight Distribution System # RP66560 does not require any additional lubrication other than greasing the coupler. The only other maintenance that is necessary keep the system clean and rust-free so it will be much less than what you're doing now with your Fastway. It's also possible your Fastway system is rated too low for you. On top of the tongue weight of the trailer you also want to add in the weight of any gear in the back of your truck behind the rear...

  • Does Curt Weight Distribution Come with a Pole Tongue Adapter
  • Weight distribution systems including # 17301 do not come with a pole tongue adapter but we do have them available separately. If you go with a chain hanging system like 17301 then you can use pole tongue adapter # RP3280. However the adapter is rated for 7,500 pounds gross trailer weight and 750 pounds tongue weight so you are limited to that. If you are talking about the shank that the head mounts to, yes, it is included. If you need more capacity you could go with adapter # RP58393...

  • Recommended Weight Distribution System for 2018 Coachmen Freedom Express
  • When a particular weight distribution system, such as the Pro Series # PS49904 referenced in your question, does not allow backing up, this is because of the friction bar design on the unit. These systems use a friction bar for sway control that works absolutely fine when driving forward, but is simply not designed for accepting the force of going in reverse. Keep in mind that backing up in an absolute straight line is okay, but you cannot turn at all when backing up. As far as their...

  • Recommended Suspension Enhancement for 2018 Ford F-150 Raptor Towing 8,000 Pound Trailer
  • For your 2018 Ford F-150 Raptor, I recommend going with the SumoSprings Solo Custom Helper Springs # SSR-117-47. These jounce-style springs feature progressive load control that will provide you with a much smoother ride when compared to the Timbren springs, especially when empty or hauling a lighter load. They have a 1,500 pound weight capacity so they will do a nice job of reducing the rear sag you are experiencing when hooking up the trailer. It will be a simple, no-drill installation....
