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.

Video Transcript for Reese Weight Distribution - WD With Sway Control - RP66560 Review

Today we're going to be taking a look at the Reese STEADi-Flex Weight Distribution System with built-in sway control. This is an all-in-one sway control and weight distribution system that evenly distributes weight over the axles of your tow vehicle and your trailer, which is going to offer better stability and better control. Ultimately it's going to create a more level ride for both the tow vehicle and your trailer. Now, this particular system is going to feature a tongue weight capacity of 1,200 pounds and a gross towing weight capacity of 12,000 pounds, and 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. Now this unit's going to feature a multi-point friction-style sway control that's going to limit side to side movement of your trailer.

It's designed to control sway as soon as it starts, and again, one of the biggest key features about the unit is that the sway control is built into the unit. It's nothing additional that you have to purchase or anything additional that you have to install. It's all built in. We're going to have these brackets right here, that are going to keep the spring bars in place for a nice, rigid system. That's going to hold the trailer in line. The unit does not use lift chains, so it's going to eliminate unwanted movement of the spring bars.

If we undo the clip right here and flip this up, you can see right here these are going to be the automotive grade friction material, or friction pads. This is going to create that friction that's needed to really help control the trailer sway. These correct any sway that may occur due to winds, curvy roads, or sudden maneuvers. These brackets and the pads are going to be located on each side, and then the other thing that you're going to have is right here in the head assembly. It's a very unique design. The system head is going to provide frictional resistance, which is also going to limit the movement of the spring bars as well, which again, limits the amount of sway that we experience, so this head assembly, once tension is applied to it, once these are fully installed, the head actually pinches the bar.

That prevents the bar from moving, which in turn prevents trailer sway. Again, multi-point friction-style sway control with this unit, and it's built into the unit. Nothing additional is needed. Now, these are going to be steel spring bars that are hot rolled and tapered for superior strength and flexibility. These bars will flex appropriately over uneven terrain for a nice, controlled, even ride. The bars are going to attach in the head assembly with a pin and clip.

Now, the unique design of the head assembly and the style of the bars really allows for maximum ground clearance with this unit. I want to bring you in a little bit closer here on the head assembly. There's a few key features that I just want to talk about real quick. It does come with the hitch pin and clip to get it secured on your hitch. The shank is included, but right here at the head assembly it's going to use a unique design when it comes to achieving the amount or pitch of the head assembly, the tilt. It's going to use this elongated washer design. Hardware's included. The washer has teeth on it and the head assembly has teeth on it, so those two go together. It's located on each side of the unit, and so the desired tilt is easily achieved using an elongated, serrated washer design. This design allows for quick and easy adjustment of the head assembly, so that way you don't have to deal with the old style, which is all those washers and a spacer rivet. To get the tilt, it's all accessible here from the outer part of the head assembly. You don't have to get internal with it. It's really nice, especially when it comes to making those fine tune adjustments. It makes those very simple, which is going to help ensure a safer, more enjoyable towing setup and situation. Now, there's also an adjustment bolt inside the head assembly that can be set once the proper tilt of the head assembly has been achieved. You just bring that out until it makes contact with this portion right here of the shank. Really nice design. The other thing I want to point out are the no-drill, clamp-on brackets. These can adjust along the trailer frame, so that's going to be these right here. These are going to adjust along the trailer frame to accommodate frame-mounted items, such as a battery box, your gas tanks or propane tanks, toolboxes or generators. These brackets can be positioned between 27 to 32 inches from the center of the trailer coupler. Now, these brackets are going to attach to the trailer frame, so you're going to have the inside portion of the bracket, outside portion of the bracket, and then when you're ready to install, or even remove the weight distribution system, this portion right here slides on and off this bracket, and then once you have it set to what you need, you just secure it in place with the included hardware. All the necessary hardware to get the unit fully installed is included. Now, the adjustable shank, again, this is included. This is going to give you plenty of adjustability. This can be used in the drop or rise positions. It's going to offer 7 vertical mounting holes and those holes are separated on center by an inch and a quarter. With the unit in the rise position and the head assembly at the highest setting, it's going to give you a maximum rise of 8 3/4 of an inch. That's measuring from the inside top edge of the receiver tube of your hitch to the top of your ball platform. With it in the drop position and the head assembly at the lowest setting, it's going to give you a maximum drop of 4 inches. Now, Reese also designed this system so it does not need constant adjustment like other weight distribution systems. Once you have it set, once you have it installed properly, everything's set to go. You don't have to worry about getting out and checking it or re-torquing or anything like that. It's all going to be set and ready to go. It's going to last a long time, and again, it does not require you to have to constantly get out and make adjustments or check everything. It's going to be a steel construction. It's going to have a powder-coated finish, which is long-lasting, corrosion resistant design. Now your hitch ball, you will need to pick one of those up. That is sold separately. It's going to require a hitch ball with an inch and a quarter diameter shank, but again, it does come with all your necessary hardware for your installation. It's also going to come with these shims right here, that can be used to ensure a tight fit between the head assembly and the adjustable shank. It's going to come with your lift handle, which eases the installation by reducing the lifting required by the trailer jack. This goes around the bar, gives you enough leverage or the proper leverage needed to get those bars in the brackets. Now, this is designed for a 2-inch by 2-inch trailer hitch receiver. It's going to fit trailer frame heights from 4 inches to 7 inches tall. It's going to fit trailer frame widths from an inch and a half to 2 inches. The distance from the center of the hitch pin hole to the center of the hitch ball hole is going to be around 13 inches when the unit is square and straight, and Reese is going to cover this with a limited lifetime warranty. That's going to do it for today's look at the Reese STEADi-Flex Weight Distribution System with built-in sway control.

Placed my order on Wednesday and Received it on Friday. And everything seems to be just as expected. Thanks 340816

This equalizer/anti-sway hitch was a tremendous improvement over the Pro-Series that I previously used. This greatest advantage was the ability to drop the hitch 4" over the 3" drop of the Pro. This put less pressure on the bars to place them into the slide brackets with the tool. I was not trying to pull the truck down to make it level. 438066

Although I won't actually get to use my new Reese RP66560 WDH for a couple more days, I will provide some feedback regarding the assembly at this point and will update my comments after first use.......All went well during assembly, except you WILL need a 1 7/8" socket and appropriate breaker bar/torque wrench to install a hitch ball on the draw bar head assembly. Hmmm....I didn't have a socket that large in my tool box, so I ordered one. Problem was, the new socket was simply too large to fit in the "pocket" where the trailer ball mounting nut is. So, it really helps if you have an excellent set of tools to conquer this challenge. Not sure how I'll handle this one just yet. I also want to add that shipping was ultra fast, so I know the team at Etrailer has their act together. I am going to need additional trailer items, and will be sure to order those from Etrailer as well! A word regarding customer support.......It is all too common these days to see so much critical feedback (mostly justified, I am sure) all over the internet. But at the same time, positive feedback just isn't provided as often as it should be. On that note, I would like to provide some EXCELLENT feedback for Etrailer customer agent Heidi M. Not only did she immediately understand my dilemma in selecting the right weight distributing hitch for my trailer, she was quick to make knowledgeable suggestions of potential hitches that would meet my towing needs. I settled on one of her recommendations that not only fit the bill now, but would also provide room for growth into a larger trailer in the future if needed, all while not breaking the bank. THANK YOU, Heidi M., for being so helpful! 549142

I bought this hitch to tow our family's Coachmen Catalina 22FBS with an early 2000s Ford Expedition. Prior to this hitch we just had a ball and friction sway bar. Rightly so, it is night and day difference between the two. My wife and I both take turns towing and the sway bar never really made either of us comfortable due to bucking and sway next to other large vehicles on the highway. With this hitch there is no more bucking and very little sway. What sway there is corrects/dampens itself very quickly. On smooth or gentle hills The two vehicles feel like one and you don't really notice the trailer when towing. I was hesitant about spending the money on this hitch which is why we tried the sway bar first, but now that I have it I absolutely love this hitch and we're both extremely happy to have made the switch. I still have some learning and adjusting to do to get the tow vehicle at the right angle which is something that I think is a bit of a pain to zero in, but I can't really say it's related to the hitch and is more my issue of figuring it out. I'm assuming when I bought this hitch in early 2016 it was new because etrailer was one of the few places I found that was selling this hitch. The price at the time was much cheaper than anywhere else online or locally and the shipping was decent. I live within two hours of the etrailer facility so I can't really provide feedback for shipping long distances. I've never used any other type of weight distribution hitch so I can't speak of comparisons, but I found this to be easy to understand the installation instructions and the use instructions too. 330481

Provides great stabilization, I have never felt a bit of sway. Bars need to be lubricated every time where they rub on the head or they make a ton of noise when making low speed turns. Also have had to tighten the pads on the frame multiple times they seem to loosen up. Other than that I’ve been very happy with the system. 489481

Still need to tighten pads a lot. Only uses rear pads and that pad has crumbled quite a bit. Used a heavier duty grease on the bars where they move on the head and it seems to cut down the noise and having to do it every time.

Tow bar works great - towing a 35 'travel trailer and have had no issues. Tracks great with very little sway. Takes a vew extra minutes to hook up, but well worth hte time. 448452

- RP66560

This system was fairly easy to install, the instructions could have been a little better but overall it was fine. I pull a 32' video game trailer with an 04 Sierra 2500hd and this system relieved about an inch of squat. I could probably adjust it to help more but I am pretty happy with how it sits now. The main reason I bought it was actually for sway control and on that front it works wonderfully. The only downsides to this rig is that 1 it is noisy. Not when driving down the interstate or anything. But when making tight turns in neighborhoods or parking lots etc. It isn't a huge deal most weight distribution/sway systems make some noise, so it's whatever. 2: the break pad type things wore down badly when I first installed it because my trailer tongue had a rubberized coating on it that allowed the brackets to move some. So having a part that will need to be replaced is something to consider. Also the small pins that keep the "doors" closed on it are easy to bend up, especially if the bars have a bit of side pressure on them. I strongly recommend going to lowes or somewhere and buying yourself some spares. 640115

Ordered Reese Stedi-Flex w/sway control on Monday evening and received it Friday morning of the same week. It will be a bit before I can set it up as my trailer is on order, but i will definitely be a return customer. I appreciated the follow up on the delivery and service. 425262

After a month of looking and reading responses, watching various videos and talking with users; I decided on the RP66560. My situation is: 2012 Chevy 2500 ext cab 4wd with 6.5' bed. I followed the directions which were easy to understand and all parts fit perfectly. I am towing a 30' full width 9500 lb travel trailer with two slide outs. Following directions I was able to complete application with no change with front or rear measurement. A key note - use real bearing grease on the WD bars not just spray grease; not enough lubricant. Also, look at the set back before you buy to ensure you can use it. For some assurance I bought a 25k 1" rise hitch ball. I pulled the trailer with a good 20-30mph cross wind with no sway at all. There was zero bucking over bumps or movement on uneven roads. Easy to back up with no issues. When I was done with towing I had it unhitched in 3 minutes. This WD hitch far exceeded my expectations. 608520

For the most part this has been an easy WD system to live with. I tow a 25' travel trailer with a '12 Ram 1500 and it tracks straight even in strong cross winds. I was also suprised at how turning radius doesn't seem to be affected with it attached. My only complaint is how the covers for the ends of the weight distribution bars are secured. The little pins are placed so far to the end that a small movement in the cover allows them to be completely ineffective at securing the cover. This is important because these covers keep the WD bars from slipping off their resistance pads. Thankfuly so far I haven't had a cover slip or bounce open allowing the bar to release its tension after slipping off the pad. I can't imagine that would end well at highway speeds. I've traveled about 5,000 miles with this hitch and so far so good. Hopefully it stays that way. Lastly if these were designed this way on purpose, it would have been nice to have had a note about it in the manual to ease ones concerns. 409535

The hitch is still performing well, but the bar covers continue to concern me.

Received by hitch in a timely manner and in an intact box. I opened it to make sure all parts where delivered. This thing is built like a tank. No doubt that it will do the job come towing time. 609232

- RP66560

My experience with the RP66560 Steadi-flex was not what I expected. Following the setup instructions the sway control was satisfactory, but the hitch caused significant bounce. I also did not like the weight as I have a bad back. I sold the hitch for half of what I paid and purchased an Andersen No-sway. I tow a 35 ft. Rockwood tt with a Ram 3500 dually. 440482

When your setup is bouncy that is an indicator that the weight distribution system WDS is rated too high for your setup. In order to choose the correct WDS for your setup, figure out the loaded tongue weight. This is the tongue weight of the trailer when it is all loaded with cargo and ready to be towed. You should also include the weight of anything you may have behind the rear axle of the tow vehicle. The loaded tongue weight of your setup needs to be in the middle of the range of tongue weights the WDS supports.

I installed this on my 2011 Jayco 32BHDS hooked to a 2011 GMC Sierra 3500HD single rear wheel. I’m in love with this set up. It has superior sway and bounce control compared to the other style that uses the L shaped weight distribution bars with separate sway control. My only complaint is that this hitch is excessively noisy when making tight turns through the campground or turning at intersections. If the noise exists at highway speeds, it is not even noticeable. I still gave this hitch a 5 star rating though, because it does a perfect job of weight distribution and sway control, and the noise doesn’t have anything to do with that part. It does what it promises. The noise is acceptable due to the great performance. 557551

Great Service!!! Great Products!!!, I called and told Steve at E Trailer that I needed a Reese Weight Distribution Hitch Asap. Steve sent me an email several hours later saying it’s on its way, I had the hitch in two days. Fast shipping , and great customer service, Thanks E Trailer for taking care of your customers. 669139

This hitch works great. No more having to disconnect trunion chains when backing around corners. It took a little fiddling with the parts that install on the trailer, trying to get the saddles to the correct height. The hardest part about installing the hitch for use is getting the reducing sleeve to line up with the hitch when installing it in the truck. 663651

- RP66560

Based on the features I wanted and the trailer + tongue weight ranges I was looking for I was split between this Reese model and the FastWay E2 hitch. Rebecca with etrailer was a big help in helping me make the final decision to go with the Reese model as it has an active tongue weight range that it can support opposed to the FastWay that can only support up to 800lbs tongue weight. Great experience, fast shipping and fair pricing made the decision to buy from etrailer easy, free shipping didn't hurt either. Thank you! 660202

I love it. It’s a awesome product and I would recommend this to anyone pulling a travel trailer I am so glad I purchase this product. It worked perfectly Etrailer is the best company for anything trailer thanks for everything 643304

I purchased a new RV camper (dry weight around 6,300lbs) in March 2018. I decided to change from my Equalizer brand weight distribution hitch to a Reese Steadi-Flex. After a year of owning it, I would say I prefer the Reese Steadi-Flex over the Equalizer. I thought it was much easier to install initially. The adjusting to get the camper level was much easier with the Reese hitch. After the initial hook-up, they are about the same to connect to the camper. While fairly similar, I think the Reese offers a little better sway control, but that is tough to tell for sure. 621521

Ask the Experts about this Reese Weight Distribution Hitch

  • Is It Okay To Use the Reese 12K Steadi-Flex On a Trailer Under 12K
    Yes, you can use a weight distribution system that is overrated for the trailer you intend to use it with. However, the best performance will come from a system that matches the total tongue weight of your towing setup. In order to find the total tongue weight of your towing setup you will need to calculate the loaded ready to tow tongue weight of the trailer plus the weight of any cargo stored behind the rear axle of the tow vehicle. The Reese Steadi-Flex Weight Distribution System...

  • Comparing the Reese Steadi-Flex, Husky Center Line, and Fastway e2 Weight Distribution Systems
    The Reese Steadi-Flex like part # RP66560, Husky Center Line like part # HT32218, and Fastway e2 like part # FA92-00-1000 are all great weight distribution systems. I recommend the Reese Steadi-Flex over the Fastway e2 and Husky Center Line because the friction pad system it uses is much quieter than the steel brackets that come with others. Furthermore, it offers greater shank adjustments (max rise 8-3/4", max drop 4") so you can switch trailers or tow vehicles down the road without needing...

  • Can Weight Distribution System be Used on a Truck with a Lift Kit
    Lifted trucks can use weight distribution systems like the Reese Steadi-Flex kit part # RP66560 that you referenced but more often than not a drop shank is needed to provide the additional drop needed. For example we have the Fastway e2 shank part # FA92-02-4315 which can provide a drop of up to 7 inches. This also can be used with the Steadi Flex system you listed. To determine the amount of drop you'll need will require you to measure from the top of your hitch opening down to the...

  • Recommended Weight Distribution Hitch for Winnebago Micro Minnie with GVWR of 7,000 lbs
    For a weight distribution system, you want to make sure your total tongue weight falls within the range of the system. Total tongue weight is not just the unloaded hitch weight, but is the completely loaded and ready to go hitch weight (tongue weight) as well as any cargo weight behind the rear axle of the towing vehicle. This total tongue weight needs to fall in the range of the system. For instance, the Reese Weight Distribution System w Shank - Round Bar - 10,000 lbs GTW, 800...

  • Shank with More Drop for a Reese Steadi-Flex Weight Distribution System
    There are certain shanks that are compatible with the Reese Steadi-Flex weight distribution systems such as # RP66560. You can use # RP3344 which will get you to a maximum of 7-5/8 inches drop. The shank is available separately but cannot be swapped out for the one that comes in the kit.

  • Recommended Weight Distribution System for a CronKhite Equipment Trailer
    We can start by getting your the coupler you need. I recommend the Trailer Coupler - Adjustable Channel Mount - Thumb Latch - Black - 2-5/16" Ball - 14,000 lbs # CTA-400. This coupler will work well with a weight distribution system. Then I recommend the Reese Steadi-Flex Weight Distribution System w/ Sway Control - Trunnion - 12K GTW, 1.2K TW # RP66560 which is compatible with the surge brake actuator. You will need to bolt the brackets directly to your trailer frame if the brackets...

  • Can Reese Steadi-Flex Weight Distribution System be Used With Hitch Reducer
    Though it is possible to use a hitch reducer sleeve in a 2-1/2 inch hitch with the Reese Steadi-Flex Weight Distribution System with Sway Control # RP66560, we have asked the manufacturer, Reese, about this in the past and they do not recommend doing so because it can reduce the capacity of the system. The best option to use the Steadi-Flex with a 2-1/2 inch hitch is to simply replace the 2 inch shank of the Reese Steadi-Flex # RP66560 with a 2-1/2 inch shank, the Curt Weight Distribution...

  • Is Weight Distribution Needed for 8,000 lb Travel Trailer Towed by 2018 F-150
    We recommend using a weight distribution system when the trailer weighs more than half the weight of the tow vehicle so in your case, with a 2018 Ford F-150 towing a 8,000 lb Palomino Puma 30FBSS I do recommend using a weight distribution system. This will ensure a level ride which will help you maintain control over your truck, as will the sway control. In order to choose the best weight distribution system you will first need to know your total tongue weight (TTW), which is the tongue...

  • Steadi-Flex vs Strait-Line Weight Distribution for a Dump Trailer with Varying Weight
    Yes, you will need to adjust your weight distribution (WD) system depending on how much total tongue weight you have. If you have a system that is rated too high then your towing setup will be too stiff. Out of the Steadi-Flex # RP66560 and the Strait-Line # RP66074 you are correct that the Strait-Line will be the easier of the 2 to adjust. They both have similar head adjustment options but when it comes to the arms it is much easier to adjust chain length and the bolts on the dual...

  • How to Figure Out Which Weight Distribution Hitch to Use With 2017 Rockwood Mini Lite 2104S
    A Reese Steadi-Flex such as # RP66559 is a high-quality system that uses friction within the brackets to keep sway to a minimum. The brackets simply clamp on so you will not have to drill in your trailer frame, and the head unit can be tilted much easier than other systems due to its use of preset positions (as opposed to the traditional method of adding washers). To choose the correct Steadi-Flex weight distribution system you will first need to know your total tongue weight (TTW),...

  • Recommended Weight Distribution for Colony Cargo 7 x 16 V-Nose Trailer
    Thank you for all of the info regarding your towing situation! For your application I recommend the Reese Steadi-Flex # RP66560 which has a tongue weight range of 600 lbs - 1,200 lbs and a max towing rating of 12, 000 lbs so it is perfect for your trailer weight. The brackets need to be mounted about 27" - 32" from the center of the hitch ball so I believe they will be able to fit just fine between the 2 bracket that you are talking about. The only other thing you're going to need...

  • Recommended Weight Distribution System for 6000 Pound Trailer with 800 Pound Tongue Weight
    I recommend using the Reese Steadi-Flex Weight Distribution with Sway Control # RP66560. This system uses integrated friction pads made from a brake pad-type material to help prevent sway, and the trunnion bars help distribute the tongue weight of your trailer while providing better ground clearance than more traditional-style round bars. Additionally, this system includes the shank needed for the weight distribution system. The brackets have a no-drill, clamp-on designed that can accommodate...

  • Will a High Coupler Height On a Boat Trailer Affect Stability
    I would assume as well that boat trailer manufacturers have some inclination as to how the trailer will perform with a boat attached as that is its purpose after all but I don't have specifics on this. The coupler height however does not necessarily have a direct affect on the center of gravity for the trailer because some are mounted on top of the tounge which appears to be the case for you. Therefore, I would not fret too much unless you start to run into issues with stability. If...

  • Recommended Weight Distribution System for Trailer with 650 lb Tongue Weight and 8995 GVWR
    The Reese Steadi-Flex Weight Distribution System w/ Sway Control # RP66560 is what I recommend for your trailer with a 650 lb tongue weight. This system will work well with your loaded tongue weight as well as any cargo behind the rear axle of your 2015 F-150. This is the total tongue weight you need to account for with your system. This weight distribution system has integrated sway control utilizing trunnion bars and friction material that is similar to automotive brake pads. This...

  • Which Style Weight Distribution Bars Have the Most Ground Clearance
    Trunnion bars offer more ground clearance, are easier to install, and are considered more heavy duty than round bars. Round bars come down, make a 90 degree turn, then go straight back to the brackets which is why they have less ground clearance than trunnions which exit straight out of the head. I have linked an FAQ article with even more information for you to view. When choosing a weight distribution system, you will want to go by the tongue weight of the trailer when loaded and ready...

  • Reese Steadi-Flex And Equal-i-zer Weight Distribution Systems Comparison
    Both of the weight distribution systems, part # RP66560 and part # EQ37120ET you asked about will do a great job for you. They are similar in tongue and weight capacity at 12,000-lbs for towing capacity and 1,200-lbs for tongue weight capacity. Both feature sway control and use clamp-on no-drill brackets. Both of these systems will allow you to back up with the bars attached and will work with surge brakes. The SteadiFlex system uses brake pad material in the sway brackets, where the...

  • Adjusting Tilt on Weight Distribution Head for Desired Tongue Weight
    For the Reese Steadi-Flex Weight Distribution System w/ Sway Control # RP66560 to increase your tongue weight and put more weight on the tow vehicle rear axle, you would angle the head up. Another way to add more tongue weight is to lower the brackets on the sides if possible so less weight is on the spring bars, so not so much weight will be distributed to the trailer frame and more will be at the coupler.

  • Weight Distribution with Sway Control Recommendation Ford Super Duty Towing a 7300 lb Trailer
    The dual cam style of the Strait-Line series weight distribution systems works proactively to prevent sway before it starts. Whereas, the friction sway control of the Steadi-Flex series systems do help with sway, but they do not work to prevent sway before it starts like the dual cam systems do. Both of these sway control styles will help with sway, but if you are looking for the better option for sway control I would recommend you get the dual cam setup. The best way to pick out...

  • Reese Steadi-Flex Weight Distribution System for Trailer with 800 to 850 Pounds Tongue Weight
    When choosing a weight distribution system you want to choose one that your total tongue weight falls right in the middle of the system's range. That's the reasoning behind the options to choose. So if you are to filter by 800 or 900 pounds tongue weight you'll come with the Reese Steadi-Flex # RP66559 rated from 500 to 1,000 pounds and the # RP66560 rated from 600 to 1,200 pounds. I know it can be kind of confusing. Since your trailer's tongue weight is between 800 to 850 pounds...

  • Weight Distribution System Recommendation for a Dump Trailer Towed by a GMC Sierra 2500HD
    For your situation, I recommend looking at the Reese Steadi-Flex weight distribution systems. As you mentioned, you will want a weight distribution system with a large tongue weight range. The Reese Steadi-Flex System, # RP66560, has a maximum tongue weight capacity of 1,200 lbs and a minimum tongue weight requirement of 600 lbs. This would be an ideal system for a dump trailer with fluctuating loads. This system also has integrated friction sway control. If your tongue weight dips below...

  • Upgrading to 1,200 Pound Weight Distribution Spring Bars for 7,725 Pound Trailer
    The dry hitch weight is the weight with the trailer empty of everything including propane and any other cargo, water, and other items. The gross weight of your 2017 Grey Wolf 26DBH is 7,725 pounds. That is the maximum the trailer can weigh when loaded and ready to tow. The empty weight is 5,795 pounds. So is 725 is the dry hitch weight then that is 12.5 percent of the gross trailer weight. That means that when loaded to the max 7,725 pounds the tongue weight would be around 965 pounds....

  • Will Spring Bars on Reese Strait-Line Weight Distribution Fall Off in Sharp Turns or Backing Up
    The only time I have heard of spring bars coming off of a Reese Strait-Line weight distribution system such as # RP66074 is if the system is not set up properly. Provided that it is installed according to the instructions including the placement of the dual-cam sway control the spring bars will not come off when making sharp turns or backing up.

  • 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...

  • Recommendation for Grand Design Imagine 2600RB Porpoising While Using Weight Distribution System
    Your 2017 GMC Sierra 1500 5.3L V8 has a towing capacity of 6,000 lbs. Porpoising can have to do with weight not distributed properly. I recommend you use the Reese Steadi-Flex Weight Distribution System w/ Sway Control # RP66560 which is rated for 600-1200 lbs total tongue weight. The total tongue weight is not only the loaded trailer tongue weight, but also any cargo behind the rear axle of your truck. This combination needs to be between that 600-1200 lbs. This system will help to...

  • Will the Reese SC Weight Distribution System with Sway Control Provide Adequate Turning Ability
    All weight distribution systems will limit your turning radius somewhat when backing in tight situations. That being said, the Reese Steadi-Flex Weight Distribution System with Sway Control, # RP66560, will not limit your turning radius when traveling forward and making tight turns, and will allow you to make pretty tight turns when backing. It is always a good idea to remove the spring bars before backing into situations where very tight turns may be required, to prevent damage to the...

  • What Happens if Weight Distribution System is Rated Too High
    Yes, if you use a weight distribution system that is rated too high for the tongue weight of a trailer the ride quality will be incredibly stiff and harsh. You want to ideally pick a system that has a tongue weight range where your tongue weight falls right in the middle. So an Equal-i-zer kit like the part # EQ37060ET which has a range of 200-600 lbs would be great for your setup that would be around 500 loaded.

  • Backing Trailer While Using Reese Steadi-Flex Weight Distribution System # RP66560
    During normal backing, it's perfectly acceptable to leave the bars in place, but if you're in a situation where jackknifing the trailer would be a possibility, I'd highly recommend removing them to prevent damaging anything. The Reese Steadi-Flex weight distribution system you mentioned, part # RP66560 would be an excellent choice if the fully loaded and ready to tow tongue weight of your trailer is between 600 and 1200 lbs. I'll link you to some FAQ articles that you might find helpful.

  • Is a 1,200 Pound Weight Distribution System too Big for a Trailer with 500 Pound Dry Tongue Weight
    A Reese weight distribution system is going to have a tongue weigh capacity range. The 1,200 pound systems are rated for 600 to 1,200 pounds of tongue weight. The tongue weight will increase once you load the trailer. But, you also have to add the weight of anything loaded behind the rear axle of the towing vehicle to the trailer tongue weight. So if your trailer tongue weight when loaded is 600 pounds and you have 200 pounds of stuff behind the rear axle of your Ram, that puts the tongue...
