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  • Don't want to have waste time with difficult, outdated adjustment methods during setup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 500 lbs – 1,000 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.

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

Head Adjustment

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.

The item arrived with a large hole in the box. One of the pieces to the hitch was missing. I called up etrailer and spoke with Noah and he was great. I had the part in 2 days. Thank you etrailer for wonderful customer service!!!! 641773

Awesome product!! Even better service specially after the purchase when parts were missing. The staff at etrailer took care of it immediately! 612976

This product works very well, I have used several different types of distribution systems in the past. The integrated sway and weight distribution saves time and effort. Once set up into place there is no sway and the distribution really helps to make pulling our camper much more pleasant. 638372

Thanks for the technical help and advise on selecting the proper hitch for my application. The hitch arrived on the date you promised-thank you again. It came in what appeared to have been a box at one time (lol) completely destroyed and open. Thankfully all parts appear to be there. I am very happy with the quality of the Reese Steady Flex hitch RP66559 and look forward to many years of towing. E-Trailer is anyones BEST on line source for your equipment needs. Thanks very much- Bob Sac 290567

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

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

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

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

Easy to install. No sway. Easy hookup and disconnect . Love being able to back up without unhooking the bars. I get positive impressions from fellow campers. You need to lmprove packaging. It arrived in a jumble of torn up cardboard and parts. Fortunately all the parts were thier. 480037

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

Fast delivery, easy, straightforward installation and setup. This is a nice hitch! My only gripe is that it can't be ordered without the shank, which was too short to let me open my F150 tailgate and had way too much drop, which would have required cutting off. (Luckily a friend had a longer shank with less drop and we were able to swap.) 548206

Purchased this Reese Stedi-Flex Weight Distribution System with Sway Control to use on our 2016 Silverado pulling our new 26' Winnebago Travel Trailer. Just returned from a 300 mile round trip and really enjoyed the way it handled as we drove both flat ;land and Arizona mountains with steep grades and curves. Really handled well. Hook up with the spring bars was a snap and feel rally safe with this system. This was the first trip with our new trailer and we were most delighted with the way that the truck and trailer worked together. Always knew Reese made good products and would happily recommend this system and etrailer. Thank you -- 549909

Working good however, I get some up & down bounce in the front of the truck. Checked with customer service and determined that I needed to change the head angle to put more weight on the front of the truck. Made that change but have not yet pulled the trailer. Will in about two weeks and then will know if I helped it or not. I feel sure that I have made the right adjustment., Thanks etrailer for your help.

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.

This system has preformed very well in a lot of different conditions. Easy hook up and unhooking. The only reason I didn’t give it Five stars is it continues to be a little noisy when turning which is not an issue for me . It could be for others. 472950

I am really impressed with the Reese Steadi-flex hitch. It stopped most of the trailer sway I was having with my Puma. It sits higher on the axles and was affected more from wind and semi-trucks passing. Driving is much more stable now. 824458

- RP66559

I bought this using reviews on its simple design. I have never had a trailer that needed this type of hitch. After viewing the video install guidelines I went to work and the install went flawless. I did have to go to a garage and have them torque the one nut for me since I did not have a big enough socket. I would recommend this product highly. My trailer travels well and keeps my truck level. 807864

    Using a weight distribution system won't increase the 650lb tongue weight capacity of the vehicle, so you'll either need a more capable tow vehicle or a trailer that's lighter. In some cases where the capacity of the hitch is less than the capacity of the vehicle, using a weight distribution system can raise the capacity of the hitch itself, but the manufacturer's stated towing capacity of the vehicle will have the final word.

    The Andersen system you have now is pretty quiet but it's downside is that anything over 500 lbs of tongue weight is too much for the system to help.

  • Recommended Weight Distribution System For 2014 Ford F-150
    For your 2014 Ford F-150, you will not need to modify your factory hitch to use a weight distribution system with the travel trailer you mentioned. When looking at weight distribution, you want to consider the loaded weight of your trailer tongue as well as any cargo behind the rear axle of your truck to determine the total tongue weight. You want that total tongue weight to fall as close as possible to the middle of the tongue weight range of your weight distribution sysem. With the...

  • Quieter Weight Distribution System Recommendation for Trailer w Unloaded Tongue Weight of 490 lbs
    The two louder systems are the two that work the best strangely. The Equalizer systems groan pretty loudly from the friction and the Straitline systems makes loud popping noises as the cams move around during corners. The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining...

  • Recommeneded Weight Distrubution System For 24 Foot Forest River Wildwood 24QBXL Camping Trailer
    The Reese Steadi-Flex Weight Distribution System w/ Sway Control # RP66559 is a very good option for your application. With weight distribution, you want to go off the total loaded tongue weight of your trailer as well as any cargo behind the rear axle of the towing vehicle. The listed tongue weight you gave of 499 is most likely the dry load rating as you stated and the loaded tongue weight is typically between 10-15% of the total loaded weight of your trailer, then you add the cargo...

  • Weight Distribution System Recommendation for 8,000 LB Travel Trailer
    Typically the tongue weight of a travel trailer is 10 to 15 percent of the trailer's fully loaded weight. Since you mention that your fully loaded trailer is probably close to 8,000 pounds, a tongue weight of 750 pounds sounds a bit on the light side. I recommend that you verify the tongue weight and fully loaded weight of your trailer just to make sure that you are purchasing the system that is best for you. I am including an article that goes over ways to measure tongue weight. If...

  • How Much Drop with Shank of Reese Steadi Flex Weight Distribution System
    Sounds like you only would need a drop of 3 inches to allow your trailer to be towed level. The Reese weight distribution system part # RP66559 can do up to 4 inches of drop so it would work well for you and not require you to get a different shank.

  • Weight Distribution and Sway Control for a 2006 Lexus GX470 Towing a Featherlite Open Car Trailer
    I recommend Reese Steadi-Flex Weight Distribution system, part # RP66559, if the tongue weight of your trailer will always be less than 1,000 lbs fully loaded and ready to travel. The Steadi-Flex will help to control sway and will reduce the stress on the vehicle auto-leveling system. You will need a properly sized hitch ball to complete your installation, the compatible hitch balls we offer can be seen at the link below.

  • Recommended Weight Distribution System For 3100 Lb Trailer
    The best way to determine what system will work for you is to know what your total tongue weight is. The total tongue weight is the tongue weight of your fully-loaded-ready-to-tow trailer added to the weight of any cargo you place behind the rear axle of the tow vehicle. You will then want to find a system where your total tongue weight falls near the middle of the tongue weight range for the system. Getting a system that is too small will be useless, but getting a system that is too big...

  • Weight Distribution for a 2013 Toyota 4Runner and 3,700 Pound Camper Trailer
    Weight distribution is recommended anytime the trailer weight is at least 50 percent of he vehicle weight and/or the rear of the vehicle squats when the trailer is connected. Your trailer at 3,700 pounds is greater than 50 percent of the weight of your 2013 Toyota 4Runner so weight distribution is recommended. To determine the best option you will need to determine the total tongue weight of trailer. This is calculated by taking the tongue weight of the trailer when loaded and ready...

  • Size Bolts that Secure Head of Reese Steadi Flex to Shank
    Your best option honestly is going to be to a local hardware store and tell them the size bolts you need. They are going to have them in stock and you'll be on your way. We can't really get just the bolts from Reese so it wouldn't be a great idea to try and get them from us. The size is 3/4-10X5 and 3/4-10X4 like you mentioned.

  • Recommended Replacement Weight Distribution Shank with Drop for Reese Steadi-Flex System
    Your Reese Steadi-Flex Weight Distribution System # RP66559 is compatible with many different drop shank options. The Reese Weight Dist Shank # RP3344 has a maximum drop of 7-5/8 inches and a minimum drop or 6-3/8 inches. You can alternatively use the Curt Weight Distribution Shank # C17124 with a maximum drop of 7-1/2 inches. I personally recommend the Curt shank to save you some money and get you a great working option.

  • Reducing Sway While Towing a Trailer with a 2013 Ram 1500 5.7L
    Instead of adding suspension enhancement to your truck I suggest using a weight distribution with sway control problem to solve your problem. Especially, if you already have air springs installed. To choose the right system you'll need you trailer's loaded and ready to tow tongue weight and the amount of weight stored behind the rear axle of your 2013 Ram 1500. For example if you find your loaded trailer's tongue weight to be 750 pounds and then you add 150 pounds in your Ram's bed...

  • Looking for Weight Distribution System Compatible with Surge Coupler on Trailer
    Although Curt tells us that their chain suspended W/D systems will work with surge couplers, I typically don't recommend a chain suspended bar system for trailers with surge or hydraulic brake couplers. In my opinion, the tension provided by the spring bars can prevent proper compression of the coupler when the tow vehicle brakes. For a surge coupler equipped trailer, I much prefer the Reese Steadi-Flex or the Equal-i-zer system which allows free movement of the coupler. If you'd care...

  • Recommended Weight Distribution System for 2000 GMC Yukon Towing 22 Foot Travel Trailer
    To choose the correct weight distribution system you need to add your trailer's loaded and ready to tow tongue weight to the amount of weight you'll have stored behind the rear axle of your 2000 GMC Yukon. If your total tongue weight between the loaded trailer and Yukon is over 800 pounds then you'll need a system like the Reese Steadi-Flex # RP66559. It's rated up to 1,000 pounds tongue weight and uses similar brackets and friction pads to the SC.

  • Reese Steadi-Flex Weight Distribution for a Trailer with 700 to 1,000 Pounds Tongue Weight
    Since your tongue weight can reach 1,000 pounds I actually recommend going with Reese Steadi-Flex system # RP66560. It is rated for 600 to 1,200 pounds tongue weight so it completely covers your 700 to 1,000 pound range. The only other thing you will need is a properly sized ball, # 19286. I have included links on weight distribution and sway control, the Steadi-Flex system, and determining tongue weight for you.
