Is this right for you? Product Expert Lindsey S says:

Yes, if you:

  • Experience pretty significant trailer sway on a regular basis
  • Don't want to have waste time with difficult, outdated adjustment methods during setup
  • Have a trailer with 700 lbs – 1,400 lbs of tongue weight

No, if you:

  • Want a maintenance-free hitch - you'll have to tighten and eventually replace the friction pads on this
  • Hate noise - the friction pads minimize grinding sounds, but the system is still pretty loud during turns
Friction in brackets and in head works to prevent and correct trailer sway. Chainless brackets with automotive-style friction pads hold spring bars firmly in place to help keep trailer in line with your tow vehicle. Adjustable shank included.

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.

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

Works good, really makes pulling my 32’ enclosed trailer a more pleasurable experience. One of the brake pads sheared off the backing plate, I called Reese and they sent 4 new pads. It took a couple of months for them to get to me. All in all, i’m Pleased with this hitch. 757518

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

Greater capacity then my current round bar type. The round bars on mine keep falling out and I decided to get another type with higher capacity. You can not go wrong with etrailer.com. 679018

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

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 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 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

Review from a similar Steadi-Flex in Weight Distribution Hitch

I Read the manual twice and was able to install the hitch without any problems. All the parts went together great. The hitch grip carrying tool came in handy. Im 74 years old and weigh only 150lb. so I would highly recommend the hitch grip if you plan to buy a hitch for WD with sway correction. In the future if I need a truck or camper item I will check first to see if E-trailer has the part, if they have it that's who I wii purchase it from. E-trailer shipped my parts to me fast-had a great savings in cost and provided me with more information about the items than any other company ever did. I also give E-trailer 5 stars. I hope this review helps you decide on your items. 613743

Review from a similar Steadi-Flex in Weight Distribution Hitch

Works great. I tow a 3,500 lb bayside pop up camper with my 2009 Nissan Pathfinder. Without the weight distribution and sway bars the system would be unsafe to tow at freeway speeds. With the system it is solid and I have felt comfortable even on winding mountain roads. Installation was straight forward and took 1-2 hours. I would absolutely get a system like this that is backup capable. The brake pad material is holding up well after 1 year. 505033

Review from a similar Steadi-Flex in Weight Distribution Hitch

I purchased the Reese Steadi-Flex WD w/ sway control system about a year ago. I towed my 6500# 31ft camper on 18 trips covering over 3200 miles. The hitch performs flawlessly, its easy to install, and easy on/off. The connection process only takes a few minutes and a few people that have helped me hitch or unhitch the camper have commented on the hitch about how easy it is to use. The brake pad material has flaked off a bit, but I don't see this as a flaw, rather as a function of the design. Again, the hitch is fantastic and allows the camper to tow like a dream with my 2013 F150 Super Cab. I would recommend this hitch to anyone. 608642

Review from a similar Steadi-Flex in Weight Distribution Hitch

Works extremely well on a 20' enclosed trailer pulled with a 2007 GMC short bed half ton. I have never owned a trailer where one of these was needed, so this was a first experience. Read the instructions before I picked up the trailer and did the measurements carefully before and after hook-up at the dealer. After hook-up, truck and trailer sat perfectly level. Now for a 2-hour (empty) road test. Almost felt like the trailer wasn't back there. Normal creaking around slow, 90 degree turns in town; no noticeable sway on the highway. At home, after unhooking, I noticed the bars were only touching the back edge of the brake pads and starting to chip the edge slightly. Loosened the frame brackets and tilted them bottom-forward as far as the bolts would allow. Didn't need much. Another test run, and the bars lay perfectly parallel to the brake pads. Made two trips at highway/freeway speeds last summer, not quite fully loaded. Still, absolutely no unnecessary sway to speak of, even while passing or being passed by tractor trailers. Quite stable and never felt dangerous or unsafe at all. Brake pads are no longer chipping at the rear; appear to be wearing evenly as they should. My trailer dealer was impressed with it enough he asked for the model number so he could consider stocking them himself. 603924

Review from a similar Steadi-Flex in Weight Distribution Hitch

Outstanding Job to the etrailer team on communication, all the way from receiving my payment to hitting my doorstep they let me know where my order was. I was impressed with the hitch setup the way it’s designed. Now the only thing I was disappointed about was the way the Ball nut sets up into a cavity and if you don’t have a socket to get to it , you better round one up before it gets delivered. I think that information needs to be added to the description. 476071

Joe, A 1-78” socket and torque wrench capable of manufacturers specified torque is needed for assembly. If needed, your nearest body shop or RV dealer will have tools necessary for hitch ball assembly. A fee may be applicable.

Review from a similar Steadi-Flex in Weight Distribution Hitch

I installed this hitch while my trailer was in winter storage. The instructions were very good, and it was not difficult to install. A few weeks ago I got the trailer out of storage and was able to verify the measurements of the setup were exactly correct. I then towed my 25 foot travel trailer more than 2000 miles and could not be happier with the ease of hookup, unhooking and towing. The weight distribution was perfect and sway control was much better than with the old pro-style chain and torsion bar system I had used for about 30 years. I wanted a hitch that required less physical exertion to hookup and unhook, and I wanted better sway control. This hitch is the answer. It makes some noise at slow speeds, sometimes sounding almost like a horn or a low-pitched squeal, but I believe it is less noisy than other similar products, and it less noisy than my old system. I bought this hitch after doing considerable research, then talking with a very helpful salesperson at etrailer. When I called back with a followup question a couple of hours after I placed the order, I talked with a different salesperson who was equally as helpful. I received the hitch within days of the order. I then sent an email to etrailer with a question. Within about a day, they replied with a message from the manufacturer that answered my question. Over the years, I have purchased several items from etrailer and have always been pleased with their service. I strongly recommend this Reese Steadi-Flex hitch and etrailer. 489150

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

    Most likely yes, the shank that comes with the Reese Steadi-Flex Weight Distribution # RP66561 that you referenced can only do a drop of 2-1/4 inches. 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.

  • Correct Weight Distribution System Needed for an Outback 240URS with 7,500 lb GVWR
    If the GVWR of your Outback is 7,500 lbs and you are already at that prior to loading up your quad then you either need to leave some cargo behind or leave the quad behind. If the full 7,500 lbs that you are estimating includes the weight of the quad then you should be okay. To measure your tongue weight (TW) you need to load your trailer up and us either a TW scale like part # 5780 or a method highlighted in the attached helpful article. Keep in mind that a properly loaded trailer will...

  • Comparing Reese Steadi-Flex And Equal-I-Zer Weight Distribution Systems
    The Reese Steadi-Flex system # RP66561 was introduced last year so there are not a lot of reviews available yet. The system works really well to help prevent sway with the sway control built into the head and the brackets. Some of the features like the adjustable head makes this system attractive. This system is designed for tongue weight between 700 and 1,400-lbs. The hitch ball is sold separately for this system. For a 2-inch ball I recommend part # A-90 and for a 2-5/16 inch ball I recommend...

  • Comparing the 1,400 lb Steadi-Flex # RP66561 and the 1,200 lb Steadi-Flex # RP66560 WD Systems
    That is an excellent question. When you are trying to determine what Weight Distribution (WD) system to use, you need to add the Tongue Weight (TW) of your loaded and ready-to-go trailer, and any weight that is behind the rear axle of your tow vehicle. The best way to figure this out is to load everything up as if you were getting ready to go on a trip and then choose a WD system based off of that. Another thing to keep in mind is that you want the TW of your loaded trailer plus the...

  • Recommendations To Reduce Sway On 14K Trailer Towed By 2008 Dodge Ram 3500
    The weight distribution system that you selected, Reese Weight Distribution, part # RP66561, is a friction sway control system. A friction sway control will help to stop trailer sway, but does not start working until the trailer has already begun to sway. I would recommend going with a dual-cam sway control, like the Reese Weight Distribution System, part # RP66130. Dual-cam sway control acts to stop trailer sway before it starts. I have a friend who towed a car hauler with friction...

  • 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...

  • Weight Distribution and Powered jack Recommendations for a Trailer with 1,100 Pounds Tongue Weight
    When choosing a weight distribution system you will want your trailer tongue weight, when loaded and ready to tow plus the weight of anything loaded behind the rear axle of the tow vehicle, to be near the middle of the system range. For a tongue weight of 1,100 pounds, you would want to go with # RP66561, 700 to 1,400 pounds tongue weight capacity. For a 2-5/16 inch ball use # 63840. I have included a link to our FAQ article on weight distribution and sway control for you. For a jack,...

  • Recommended Weight Distribution System For Toy Hauler With 1,012 lb Tongue Weight
    For your new toy hauler with 1,012 lb tongue weight, I recommend the Reese Steadi-Flex Weight Distribution System w/ Sway Control - Trunnion - 14K GTW, 1.4K TW # RP66561. This system is rated for a total tongue weight (total loaded trailer tongue weight and cargo weight behind rear axle) between 700 and 1400 lbs. This system has clamp on brackets and uses trunnion bars along with automotive grade friction material for sway control. For a hitch ball, I recommend the 2-5/16 inch # 19286. Your...

  • 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...

  • Recommended Weight Distribution For 2006 Ford F-350 With Lift Kit Towing Trailer
    Thank you for the photo of the trailer you are planning on towing. Since you plan on towing a trailer that size I recommend using a weight distribution system with sway control. This would keep the trailer level and the sway control will help keep the trailer steady on the road when passing large trucks and in high winds. The most important thing you need to know when selecting a WD system is the tongue weight and also the trailer weight. Tongue weight is the tongue weight of the trailer...

  • Recommended Weight Distribution System for Towing Trailer with 1,200 Pounds Tongue Weight
    To determine the correct weight distribution system you'll need to add the 1,200 pounds of tongue weight of your loaded trailer to the amount of weight you have stored behind your Chevy's rear axle. That figure needs to be within the range of the system you choose. Once you add those together the Reese Steadi-Flex # RP66561, rated for 1,400 pounds of tongue weight, is a great option. It uses automotive friction pads for sway control. For a hitch ball use # 19286. Another great...

  • Recommended Hitch Balls for the Reese Steadi-Flex Weight Distribution System
    The Reese Steadi-Flex Weight Distribution System part # RP66561 requires a hitch ball with a 1-1/4" diameter shank. Therefore, for a 2" trailer coupler you will want to use part # A-90 and for a 2-5/16" trailer coupler you will want to use part # 19286. The measurements you provided are both inline with the Technical Bulletin: TB17-01 as you can see in the attached photo.

  • Installing a Weight Distribution System on a Trailer with a Bottom Mount Coupler
    I believe the problem you are experiencing is due to the fact that the trailer has a bottom-mount coupler. You will need to have the weight distribution shank in the drop position with the head low and probably tilted towards the trailer in order to get the proper height for your trailer. The spring bars should be close to being parallel with the trailer frame. If you make these adjustments and the system still is not properly mounted, this weight distribution system probably is not...

    Sounds like you may be asking what the tongue weight capacity is for your 2013 GMC Yukon XL 1500. From the research I did it looks like your vehicle has an 1,100 lb tongue weight capacity. But I recommend you check the owners manual of your vehicle to confirm this. If you are looking for a weight distribution recommendation you will need to know the tongue weight of your trailer.

  • Weight Distribution System for a 2006 GMC Yukon Towing a Travel Trailer
    From the figures you have given me, I am going to figure that when loaded, the tongue weight of your trailer will run around 1000 lbs, which will fall right in between 10 and 15 percent of the trailer weight. This weight figure will also account for any cargo in your Yukon that is loaded behind the rear axle. It is this figure I am going to use to base my recommendation. I would go with the Reese Steadi-Flex Weight Distribution, # RP66561, that you have referenced. The main benefit...

  • Can the Equal-i-zer Shank Be Used With the Reese Steadi-Flex 14K WD System
    Yes, you can use the Equal-i-zer weight distribution shank # EQ90-02-4700 with the Reese Steadi-Flex # RP66561 that you have. This shank is rated for up to 14,000 lbs so it doesn't take away from the use of the Steadi-Flex. Review videos have been linked for you to check out.

  • Recommended WD Hitch for a 7,800-lb GVW Trailer
    When you choose a WD system you want to choose one that has a Tongue Weight (TW) range that the Total Tongue Weight (TTW) of your towing setup falls in the middle of; too heavy and the ride will be stiff but too light and you won't even know the WD system is installed. You can find your TTW by adding the the TW of the fully loaded and ready-to-go trailer along with the weight of any cargo behind the rear axle of your 2011 Silverado. Keep in mind that a properly loaded trailer will have...

  • Are Popping and Creaking Noises When Using a Weight Distribution System Okay
    Sounds like you have a friction sway control weight distribution (WD) system like the Reese Steadi-Flex # RP66561 or the Equal-i-zer # EQ37140ET. Pretty much all sway control setups use friction and that's what those loud popping and creaking noises are. They can seem a bit alarming but it's very normal and you actually don't want to grease them because then they won't be able to have that friction to help with trailer sway. It is definitely okay to use a WD that is rated higher than...
