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 - RP66559 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 the tow vehicle and trailer, which is going to offer better stability and better control. It ultimately creates a more level ride for both your tow vehicle and your trailer. This particular weight distribution system is going to feature a tongue weight capacity of 1,000 pounds. It's going to feature a gross total weight capacity of 10,000 pounds. It can be used with top mount and bottom mount trailer coupler's, 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 that you avoid sharp turns and jack knife situations. Now this unit is going to feature multi-point friction style sway control. That's really going to help limit side to side movement of your trailer. It is designed to control sway as soon as it starts. These brackets here are a unique design.

They are going to keep the spring bars in place for a nice rigid system that holds your trailer in line. This unit does not use lift chains, so that eliminates unwanted movement of your spring bars. Now I do want to point out that it's going to use automotive grade friction pads. If I undo the clip here, the bracket rotates up and out of the way. You can see that the bar is going to sit on these 2 large friction pads. As you turn or as sway occurs, the friction between the bar and the pads really helps maintain or keep the trailer in line.

That's a really nice design of the unit. These are going to be located on each bracket, so you have the friction pads located on each side of your system. Then also here at the head assembly the system head is going to provide frictional resistance, which is also going to limit movement of the spring bars as well, so we got the unique design of the head assembly. Once leverage or tension is applied to the unit, these spring bars are like pinched inside the head assembly, which again is going to keep those in line, which is going to keep your trailer in line so between the component here of the friction sway control and the components here of friction sway control, the units going to be a really nice design when it comes to preventing trailer sway and again, it corrects trailer sway as soon as it begins, so it's a really nice design of the unit. Multi-point friction style sway control with this unit. Again, it is built in, nothing additional is needed for sway control, it's all built into the unit. Now these steel spring bars, these are hot rolled and tapered for superior strength and flexibility.

These bars will flex appropriately over uneven terrain offering a nice, controlled even ride. The bars are going to attach in the head assembly with a pin and then a clip on the bottom side. Now the unique design of the head assembly and the style of the bars really allows the unit to have the most or maximum of ground clearance as possible. Now I do want to bring you in a little bit closer here on the head assembly, so we're going to scoot this up and then we're going to zoom in on it. A couple unique features about the head. Right here, you're going to see an elongated washer design. That's going to be located on each side, so desired tilt is easily achieved using an elongated serrated washer design. This design allows for quick and easy adjustment of the head assembly, which is going to allow you to increase or decrease tension on your spring bars. Adjustment of the head assembly is very important in weight distribution systems. This design simply makes making those fine tune adjustments much easier, more simple and that's just going to help ensure a safe, more enjoyable towing set up or situation. Now located right there you can see that there is a bolt that spins. There is going to be an adjustment bolt inside the head assembly that can be set once the proper tilt of the head assembly has been achieved. This is going to be rotated until it makes contact with the front face here of the shank on the unit. Now the brackets that mount to the trailer frame, these are no-drill clamp on brackets. They can adjust along the trailer frame to accommodate frame mounted items, such as your battery boxes, gas tanks, tool boxes or generators. These brackets can be positioned between 27 inches and 32 inches from the center of your trailer coupler from the center of the ball. The brackets are going to attach to the trailer frame and then you can see here, like this bracket attaches to the inside edge. This bracket attaches to the outside. Once you have those installed, this piece right here slides onto this bar and so when you're setting up or when you're taking it off, it's very quick and easy to do so. It comes with all the necessary hardware to get the unit fully installed. It's also comes with your adjustable shank that goes inside your hitch. This is going to give the unit plenty of adjust-ability. This can be used in the drop or rise positions. It's going to offer 7 vertical mounting holes and those holes are going to be separated on center by 1 1/4. If you have this in the rise position with the head assembly at the highest setting, it's going to give you a maximum rise of 8 3/4 of an inch. That is measuring from the inside top edge of the receiver tip of the hitch to the top of the wall platform. With it in the drop position and with the head assembly at the lowest setting, it's going to give you a maximum drop of 4 inches. Now Reese designed this system so that it does not need constant adjustment like other weight distribution systems meaning, once you have it installed and installed properly, you'll be set to go for a long time. There is no need to drop or to stop after a certain amount of miles and to get out and re-tighten or check. Once it is installed, you should be set to go for awhile, so that's a really nice design of the unit. Now it's going to be a steel construction, it's going to have corrosion resistant powder coated finish on it. Very long lasting, it's going to resist rust and corrosion. You will need to pick up a hitch ball. Hitch balls are sold separately. This unit is going to require a hitch ball with 1 1/4 diameter shank, but again, it does come with all the necessary hardware for your installation. It's going to come with a couple of shims right here, that can be used to ensure a tight fit between the head assembly and the adjustable shank and it's going to come with your lift handle, which eases the installation by reducing the amount of lifting required by the trailer jack. It goes under the bar, gives you leverage to get the bar up in place on the frame brackets. This is designed for a 2 inch by 2 inch trailer hitch receiver that's rated for use with weight distribution systems. It's going to fit trailer frame heights because of the unique style of bracket from 4 to 7 inches tall. It's going to fit trailer frame widths from 1 1/2 to 2 inches. The distance from the center of the hedge pinhole out to the center of where the hitch ball would mount is going to measure around 13 inches when the unit is square and straight and Reese is going to cover this product with a limited lifetime warranty. That's going to do it for today's look at the Reese Steadi-FLEX weight distribution system with the built in sway control.

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

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

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

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.

Made installation of the P3 brake controller a breeze in my Nissan Frontier. 487001

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

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

Package arrived on time and intact. Instructions adequate. Installation w/o problems, good quality hardware. Hooking up took 1/2 hour the first time, now down to about 15". My 28ft TT pulled by a 2016 F150 ext. cab w/ 3.5l eco engine was much more stable than with my old wt distributing hitch and one friction bar sway control. Felt passing trucks and crosswinds a lot less. Can actually use the cruise control. Glad I bought it, highly recommend it. 425873

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 product does exactly what it is supposed to do. Would not tow my travel trailer without it. Distributes weight evenly and controls sway. 575588

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

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

Took some time to install and set up but very happy with how it works in preventing trailer sway 617076

- RP66559

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

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

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

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

    The Curt Trailer Hitch Receiver - Custom Fit - Class V Commercial Duty - 2-1/2" # C15809 is a great option for your 2011 Ram 2500 as long as you are okay with a 24 inch hitch extension like # C45048.

  • 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...

  • 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 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. So your trailer being a total of 6,400 lbs means your tongue weight would be most like between 640 lbs and 960 lbs if you were loaded to the absolute max. That means the Reese Steadi-Flex Weight Distribution System # RP66559 would be a great choice as it has a tongue weight range of 500-1,000 lbs. Spring bar systems are much more effective...

  • 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),...

  • Replacement Friction Pads for the Reese Stedi-Flex Weight Distribution System
    The Reese Steadi-Flex Weight Distribution System w/ Sway Control - Trunnion - 10K GTW, 1K TW # RP66559 utilizes friction pads that will eventually wear down as you stated. It will take a long time for these pads to require replacing, but the Replacement Friction Pad Kit for Reese Steadi-Flex Weight Distribution Systems # RP58527 are available and easy to replace with a simple screw and nut.

  • Can the 14K Reese Steadi-Flex Spring Bars Be Used with the 10K Reese Steadi-Flex Head
    The spring bars between the Reese Steadi-Flex 10K Weight Distribution System part # RP66559 and the Reese Steadi-Flex 14K Weight Distribution System part # RP66561 are not interchangeable as they are both machined to different specifications. They may be able to fit into the socket but this is not advised by the manufacturer nor do I recommend doing so either. Unfortunately, most weight distribution systems begin using larger spring bars around 10K. With that being sad, the Reese Steadi-Flex...

  • Recommended Weight Distribution System for Quick Installation at Trailer Dealership
    The Strait-Line Weight Distribution System w Sway Control # RP66084 is absolutely a personal favorite with the anti-sway being far more effective than other systems. This system will only take a little longer than others based on layout, but I understand your concern. For quick mounting and yet a really good system with sway control, I recommend the Reese Steadi-Flex Weight Distribution System w/ Sway Control # RP66559. This system uses automotive grade friction material that the...

  • Recommended Weight Distribution System for Trailer with Gross Trailer Weight of 7,700 Pounds
    To determine the correct weight distribution system you need to add your trailer's loaded tongue weight to the amount of weight you have stored behind the rear axle of your 2016 GMC Yukon XL. Before choosing a system find those numbers and go from there. With that being said, based on what you've already told me, you're likely going to need a system rated for a at least 1,000 pounds of tongue weight once you load the trailer and the Yukon. If this is the case I recommend the Reese...

  • Recommended Trailer Hitch Receiver, Wiring, and Weight Distribution for 2013 Nissan Armada 4x4
    For your 2013 Nissan Armada, I recommend the Curt Trailer Hitch Receiver # 13188. This will be able to tow your trailer with 1 horse without weight distribution, but you will most likely need the weight distribution system for 2 or 3 horses. It will also help with sway control, so I would use it no matter the number of horses. For your wiring, if you don't have the factory 7 way, I recommend the Upgraded Modulite Vehicle Wiring Harness Kit with 4 Pole Trailer Connector # 119147KIT...

  • Does the Head of the Reese Steadi-Flex Need Adjusted for Different Loads
    The head tilt adjustments on the Reese Steadi-Flex Weight Distribution System are used to apply different amounts of tension to the spring bars. The tension on the spring bars will need to be adjusted accordingly to the trailer's tongue weight. Since the tongue weight of the trailer will change when you add or subtract your motorcycle(s), you will need to adjust them each time to ensure you are receiving the best performance from the system. Please keep in mind that a weight distribution...

  • Recommended Friction Sway Control Setup for Trailer 26 Feet Long or Weight Distribution System
    For your system, the Draw-Tite Ball Mount - 2-3/4" Rise, 4" Drop - 8-3/4" Long - 10,000 lbs # DT40201 will give you the 4 inch drop you are seeking for level coupler height. Then the friction sway control kit # 83660 comes into play for the trailer. To add the bracket for this system to your ball mount, you will need # RP26003 but you are correct that the hitch ball hole size is 1 inch so you will need to use a 1 inch diameter shank hitch ball like # C40007. To ensure there is not excessive...

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

    When looking into purchasing a Weight Distribution (WD) system you want to find one with a Tongue Weight (TW) range that the Total Tongue Weight (TTW) of your towing setup falls in the middle of. To find the TTW of your towing setup you will need to add the TW of your fully loaded and ready-to-go trailer, which you can use part # 5780 for, along with the weight of any cargo behind the rear axle of your tow vehicle. Keep in mind that a properly loaded trailer will have a TW that is 10-15%...

  • Recommended Weight Distribution Product for 2008 Suburban Pulling 5500 lb Travel Trailer
    A suspension enhancement product is primarily intended to support the weight of any cargo carried in the bed of a truck or in the cargo area of an SUV like your Suburban. A weight distribution system would be a better option, as they are specifically designed to transfer a portion of the trailer tongue weight to the front vehicle axle, which will level the right height. The first step in choosing a weight distribution system is identifying the tongue weight of the trailer when it's...

  • 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.

    When choosing a weight distribution system, it is key to know your trailer's loaded and ready to tow tongue weight. You'll then add the tongue weight from the trailer to the weight of any cargo behind the rear axle in the bed of your 2013 Ford F-150. You'll use this combined figure to choose the correct system.

  • Which Weight Distribution System Works for a 2008 Ford F-150 Towing a Keystone Passport 2100
    Congratulations on your new trailer purchase. Before we choose a weight distribution system, we want to determine the loaded and ready to tow tongue weight of your trailer and the approximate weight of any cargo you plan on loading in your truck bed behind the rear axle. This is called your total tongue weight and we will want to choose a system that can handle your total tongue weight. I am assuming your tongue weight of 530 lbs is the dry tongue weight. Once you load all of your cargo,...

  • 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...

  • Recommended Reese Steadi-Flex Weight Distribution System for Forest River Wildwood 27RKSS
    With a GVWR of 7,582 pounds you are likely looking at a loaded tongue weight of between 750 and 1,140 pounds. This is simply because the tongue weight should be about 10 to 15 percent of its loaded weight. I looked up the specs for your Forest River Wildwood 27RKSS and it appears that the 720 pound tongue weight that you mentioned is with the trailer empty. Also keep in mind that any added cargo weight coming from behind the rear axle of your tow vehicle needs to be added to your total...

  • Can a Single Weight Distribution System Be Used for Multiple Trailers with Various Weights
    Weight distribution systems are rated for different tongue weights and gross trailer weights. They are designed to work best with trailers that fall within their rating. 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 are rated too high for your setup, they will create a rigid ride, which can result in a bouncing trailer. If the bars are not rated high enough, the system will be unable...

  • Recommended Weight Distribution System Eagle 30 Foot Boat Trailer w/ Surge Brakes
    A hydraulic brake coupler works by compressing when the tow vehicle applies its brakes. The inertia of the trailer makes the coupler compress, which actuates the brakes. Chain suspended weight distribution systems can prevent the coupler from compressing properly, which reduces the effectiveness of the trailer brakes. Reese offer a system that would work perfectly on your boat trailer. The Reese Steadi-Flex Weight Distribution system, part # RP66559 is designed for trailers with tongue...

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

  • Selecting Weight Distribution Hitch for 25-ft Airstream with 7300-lb GVWR
    The ideal circumstance for a weight distribution system is to have the fully-loaded trailer tongue weight (including the weight of any cargo behind the tow vehicle's rear axle) be in the middle of the system's operating range. We offer a handy scale to make tongue weight (TW) measurement easy, part # 5780. For instance the Reese Steadi-Flex # RP66560 has an operating range from 600- to 1200-lbs. This would make it perfect for total TW of 800- to 1000-lbs. Similar system # RP66559 works...

  • What Does GTW and TW Mean and What is Weight Distribution, 2008 BMW X5
    I can certainly help you out. The TW is the tongue weight. This is the weight of the trailer at the coupler that attaches to the ball mount on the trailer hitch. It should be 10 to 15 percent of the GTW or gross trailer weight. The gross trailer weight is the total weight of the trailer. Weight distribution is a system that installs on the trailer frame and the trailer couples to a special shank on the trailer hitch. The spring bars that come with a weight distribution system take some...

  • 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...
