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.

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

The Steadi-Flex system uses the traditional washer-style adjustment method to achieve the perfect tilt. Controlling the head tilt helps you to fine-tune the leverage and maximize the amount of tension in the whole system. To adjust the tilt, simply slide washers onto the adjustment pin and insert the pin into the head assembly. To increase the angle, add a washer. To reduce the angle, remove a washer.

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

Adjustable 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.

While other brackets use relatively thin L-pins to secure the spring bars in place on the brackets, the Steadi-Flex system uses steel pieces that are almost as wide as the brackets themselves to secure the bars. These retention brackets easily pin into place once wrapped around the spring bars. As a result, you can have greater piece of mind knowing that the spring bars are secure and less likely to rattle around inside of the brackets.

Video Transcript for Reese Light Duty Weight Distribution System Review

Today, we're going to be taking a look a the Reese Light Duty Distribution System with sway control. With a six thousand pound gross trailer weight, in a six hundred pound tongue weight, part number RP66558. It's also available in a four thousand pound gross trailer weight and a four hundred pound tongue weight, part number 66557. You've decided you need a weight distribution system. The Reese Light Duty Weight Distribution System is perfect for an SUV and a small travel trailer set up as you see here. The sway control is going to help reduce the movement caused by wind, curving roads or sudden maneuvers. As with all weight distribution systems, it going to evenly distribute weight over both the tow vehicle and the trailer's axles.

This is going to provide a safer, more stable ride with less tire wear, better braking and handling. The spring bar hangers have integrated friction pads to help prevent sway. The hangers themselves do not take up very much space, making it perfect for smaller size trailers. It's a no drill installation with all the hardware provided. The kit even comes with weight distribution shank that you hook up with your own hitch ball.Speaker 2: As you can see with our hook up crosstalk 00:01:04 here at the rear.

crosstalk 00:01:10 raised up about an inch.crosstalk 00:01:06 In hitch ball, those require one inch diameter shank. The spring bars will flex appropriately over uneven terrain for a more controlled ride. The whole thing is coated in a black powdered coat so it's going to be corrosion resistant and it's going to stand up to the elements. Now that we've gone over some features, I'll go ahead and show how we got it set up. First thing we'll want to do is take some measurements on our vehicle.

From the ground up to underneath our wheel well, we've got 36 inches. We'll want to write that down. In the front, we've got 34-1/2 inches. These are the measurements we want to get back to when we engage our weight distribution system. For comparison, we're going to hook up our trailer without weight distribution and take those same measurements. As you can see with our trailer hooked up without weight distribution, here at the rear, we're squatting about 2-1/2, 3 inches and here at the front, we're raised up about an inch.

You can see the problem that we're having. The front of our vehicle is tilting upward. We'll want to take note of those measurements that way we have something to compare it to when we get our weight distribution hooked up. Then, when we re-engage our weight distribution and get it hooked back up, we're within a 1/4 to a 1/2 inch of our stock measurement. That's where we want to be. Now, if the front wheel height is higher than previously measured, the head tilt angle must be increased. That's tilted downward. If the front wheel well height is substantially lower than originally measured, an inch or more, the head tilt angle must be reduced. That's tilted upward. The next thing you want to do is make sure your trailer is level. The easiest way to do that is to raise or lower your tongue jack so that you have the same measurement in the front and in the back. We've got it. Keep in mind when setting up your weight distribution system, you need to make sure that your trailer is fully loaded and ready to go. The next thing we'll do is take a coupler height measurement. the reason we're going to do this is it's going to help us determine the correct ball height. We've got 22. We'll need to take note of that. We've gone ahead and swapped out our old ball mount with our new weight distribution shank. We've previously adjusted our ball height. I'll go ahead and show you how we did that. First, we got close to the desired height by selecting a mounting location for our bolts. First, to help us set the tilt of our head, we installed several of the included washers as spacers. The number of washers you will use will vary depending on your set up. Then to get the approximate height of your ball, you'll want to install your shank in the rise or drop position and then choose the desired location to put in your bolts. With the approximate ball height set and loosely installed, lets go ahead and line up our coupler with the ball. Now, with our ball attached to our coupler and our trailer back to level we can bring in our spring bars to help us determine the location of our frame brackets. We'll bring it in. You'll need to grab the pin and the clip. We're going to insert it between the head there. Drop the pin in when it's lined up and put the clip in on the bottom. Here's where it gets tricky. You want to be sure that your brackets are between 25 and 32 inches from the center of your coupler and you want to make sure that there's nothing interfering like your propane tanks or your battery box. You also need to position them so that your spring bar extends at least 3 inches beyond the bracket. With our bracket location determined, we can go ahead and install it. We'll then install our L-bracket and leave it loosely installed. We can repeat that same process for the other side. With our bracket torqued down and our L-bracket loosely installed, we'll need to be sure that our spring bar is 4 inches from the bottom of our L-bracket. That's for the six hundred pound system which is what we have here. For the four hundred pound system, it needs to be 3 inches from the bottom of the L-bracket. Now, if for some reason that didn't work out, you'll need come back to the tilt of your head and add or subtract washers. If you run out of washers, you may need to adjust the height of your L-bracket. The next thing we need to do is lock in the tilt of our head by torquing it down to the manufacturer's specifications. Now, we're ready to take our included tool and put our spring bars into place on the L-bracket. To make it easier, we can raise our tongue jack. How the tool works is it goes underneath the spring bar and hooks into the L-bracket. You want to stand off to the side to avoid injury. Because we left our L-brackets loosely installed, they have adjusted to accommodate our spring bars. Now, we can install a tension bracket to keep our spring bar in place. With that in place, we can now torque down our L-bracket bolts. With everything installed, let's go ahead and lower our jack. Once you get to your destination, in order to disconnect, you want to raise your tongue jack all the way up and this is going to make it easier to safely remove your spring bars. We can go ahead and remove our tension bracket. Now, we can just remove the spring bar from the L-bracket. We'll just repeat the same process on the other side. With our spring bars disengaged, we can go ahead and take them off. Now, we can just lower it back down, uncouple it and we've got it. That's going to complete our look at the Reese Light Duty Weight Distribution System with sway control at six thousand pounds gross trailer weight and six hundred pounds tongue weight, part number RP66558.

Excellent customer service and helpful installation video online. I was disappointed in the quality of the product (not etrailer's fault) due to poorly tapped holes and paint in the holes that made assembly slightly more difficult than should have been required. Just be aware of this so you don't cross thread any bolts and strip out the threads! 497723

Working well for my Boat Trailer with surge brakes. I'm happy I went with this 600/6000 LBS version instead of maxing out the 400/4000 LBS version on my 380/3700 LBS rig. I'm now towing legal again since down-sizing my tow vehicle to a 2015 Ford Flex, AWD, V6 EcoBoost, Even with the factory tow package the Flex is only rated for 200/2000 without WDS, but 450/4500 with WDS. I did a couple trips to my local lake before WDS (30 mile round trip via 45 MPH roads) and the Flex felt safe for that distance/speed, but it had a lot more trailer jolt and was not quite as stable as my old GMC Envoy XL. The WDS has improved the towing stability and ride well beyond my expectations, and is now even better then towing was with buddy's full-size Pickup. I did have to use a Pole-Tongue Adapter (RP58393), and customize the adapter mounting to my trailer, but I can already tell this added hassle and expense will be well worth it for the long-haul trips I do a few times a year. 228117

Was used to tow a 3500lb. travel trailer with YJ Jeep with a 5.3ls engine conversion. Set bars to a very light setting. Trailer tows very nicely. Great product. The braking system for anti-sway is one of best on the market. Replaceable brake pads are the way to go, just like in tow vehicle. 666976

Still can't figure out how to level the trailer! To undue the spring bars I need to raise the trailer and truck very high! Deciding whether I should just tow on the ball and not use this setup. Not very happy 655021

Wed be happy to help you get that figured out. Take a look at the set-up video Ive linked for you. If you still have questions after that, please let us know.

I just bought a new trailer that is 7 feet longer than my last and heavier and I now have a truck instead of an SUV so I needed to get a new weight distribution hinge with sway control. etrailer had all the best brands at the best price and delivery was fast. Unfortunately that's all I can comment on so far. I'm not picking up the new trailer till mid April, so I can't comment on how well it works or show pictures. I'll update later. 616797

I've towed a few thousand miles with this hitch on my Astro Van (properly equipped) pulling a 15ft open deck car trailer(~4000lb loaded with 450lb TW). I have been very happy with this purchase. The anti-sway system on the WDH works very well even with my smallish tow vehicle. No issues when towing in crummy weather with strong winds and driving rain, the hitch handled wonderfully. The sway control is fairly quiet when making sharp turns or backing up. Great product! 502392

I searched many different companys on line. I kept going back to Etrailer for many many questions regarding various other hitches and weight issues. They were extremely helpful with all my questions and very patient. Plus once I placed the order I received my order two days early. They are the best in customer service and price. I would differently use them again. 497933

Hitch works great. Sometimes use it without sway bars (for short trips), but noticeably less sway and bobbing with sway bars attached. Used with Ram 1500 and Lance 1995 trailer. After a few trips, one of the friction pads cracked and separated. Etrailer was very helpful getting it replaced quickly. No problems in the subsequent trips. 240305

Works great. I am able to tow a 3,500 lb travel trailer with a Jeep Wrangler Rubicon. Jeep sits level. No sway from wind or emergency lane changes. Works fine on mild off road trails. Hook up only takes about 8 minutes longer once the process is well known. 239998

Review from a similar Reese Steadi-Flex in Weight Distribution

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

Review from a similar Reese Steadi-Flex in Weight Distribution

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.

Review from a similar Reese Steadi-Flex in Weight Distribution

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

Still working, great product

    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 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...

  • Can I Use My Weight Distribution System Tongue Weight 800 lbs with a Trailer Tongue Weight 400 lbs
    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. I have attached a help article detailing how to determine trailer tongue weight and a help article answering common weight distribution questions, in which you may find helpful....

  • Recommended Weight Distribution With Sway Control on 2016 Toyota Highlander With 3000 Pound Trailer
    A weight distribution system is recommended anytime your trailer's weight is at least half of your tow vehicle's weight. So with your 2016 Toyota Highlander towing a 3000 pound trailer, I definitely recommend using weight distribution with sway control, instead of just sway control. To choose a system you need to use your 300 pounds of tongue weight combined with the amount of weight stored in the back of your Highlander behind the rear axle. You want to make sure you have a system...

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

  • Comparing Reese Weight Distribution System With Equal-i-zer Weight Distribution System
    The Reese Steadi-Flex # RP66558 and the Equal-i-zer # EQ37060ET systems are both very good and will work well with your 2011 Ford F-150 and your 17SD Casita trailer. The major differences are in the tilting design of the head, the trunnion bars, and the friction points. The Equal-i-zer system uses the traditional washer stacking design for the head angle, where the Reese system uses a serrated washer design so no additional washers or stacking is needed. The trunnion bars are shaped...

  • Which WD System Will Work With Reese Pole-Tongue Adapter # RP58393 Towing Trailer With Surge Brakes
    I recommend to use the Reese Weight Distribution System w Sway Control part # RP66558. This system will work with the Reese Pole-Tongue Adapter, part # RP58393, on your 2003 Honda Odyssey. It has a tongue weight capacity range of 200 to 600 lbs. and a gross towing weight capacity of 6,000 lbs. I am including a link to the installation instructions on the Reese weight distribution system. The system does not include a hitch ball. Use # 63845 for a 2 inch ball or # 63847 for a 2-5/16...

  • Weight Distribution for a 2007 Toyota Tacoma and 3,800 Pound Rpod 179 Travel Trailer
    I looked up the specs on the Rpod 179 travel trailer and found that its unloaded tongue weight is 285 and its tongue weight when loaded to capacity (3,785 pounds) is 415 pounds. Weight distribution is a good idea because it will help with rear end sag on your 2007 Toyota Tacoma as well as help with stability and steering of the vehicle and will help with stability on the trailer. Based on the tongue weight I recommend Fastway system # FA92-00-0600 which is rated for 250 to 600 pounds...

  • Recommended Weight Distribution/ Sway Control System for Towing 2016 Forest River Wolf Pup 16BHS
    To choose a weight distribution system, you'll need to first determine the fully loaded and ready to tow tongue weight of your trailer. To that figure, add the weight of any gear stowed in the cargo area of the tow vehicle behind the rear axle. I've linked to an FAQ article that explains how to do this. These combined figures represent the Total Tongue Weight (TTW) of your set-up. The TTW of your trailer should fall as close as possible to the middle of the effective range of the weight...

  • Weight Distribution for a 2014 Toyota FJ Cruiser and 2015 Airstream 22FB Travel Trailer
    First, as long as the gross trailer weight and hitch weight are within the capacities of your 2014 Toyota FJ Cruiser then it will be fine. Check your vehicle owners manual to make sure it is compatible with weight distribution. I know that many trailer dealerships will sell and install some . . . lesser quality weight distribution systems. They work but they do not work as well as other systems. So to at least take a look at your options I can go over some different models with you. First,...

  • Weight Distribution Hitch for a 2017 Ford F-150 Raptor
    In order to choose the best weight distribution hitch, you will first need to know your total tongue weight (TW), which is the tongue weight of your fully loaded and ready to go boat trailer plus the weight of any cargo behind the rear axle of your 2017 Ford F-150 Raptor. To determine TW you can use a scale such as the Sherline # 5780 or by using one of the methods outlined in the help article on determining TW I've linked for you.

  • Weight Distribution for Towing Spree Escape Travel Trailer w/ 2004 Jeep Grand Cherokee
    The Reese Steadi-Flex Weight Distribution System you mentioned, part # RP66558 is designed for trailers whose tongue weights range from 400-600 lbs. As long as the fully loaded and ready to tow tongue weight PLUS the weight of anything stowed behind the rear axle of your GC in the cargo area isn't more than 600 lbs, this system would be an excellent choice to provide weight distribution as well as trailer sway control. I'll link you to an article that will show you how to determine the...

  • Weight Distribution and Sway Control Recommendation For a Pole Tongue Snowmobile Trailer
    The first factor that we will want to check is how much room is available on your pole tongue. To use weight distribution with a pole tongue, you will need a pole tongue adapter. Our best option is the Reese Pole-Tongue Adapter, # RP58393, because it requires the least amount of tongue space. This adapter must mount at least 29 inches back from the center of the ball coupler on your trailer. If you do not have 29 inches available, then there are no adapters available and at that point we...

  • Can a Toyota FJ Cruiser Tow a 4,875 Pound Wolf Pup Trailer and Recommended Weight Distribution
    The tongue weight of 525 pounds is likely if the trailer was loaded to its gross capacity of 4,875 pounds because 525 is about 10.75 percent of 4,875 and trailer tongue weight is typically 10 to 15 percent of the gross trailer weight. So if you load the trailer to 3,200 pounds then at 10.75 percent the tongue weight would be 345 pounds. Provided that the hitch and your tow vehicle have the capacity for the gross trailer weight and tongue weight then you would be good to go. Also the...

  • Reese Weight Distribution System That Doesnt Require Drilling Holes in Trailer Frame
    Because of the amount of pressure it will be under, the Dual Cam Arm assembly must be bolted to the frame as outlined in the instructions. I can certainly understand your reluctance to drill holes in the frame of your brand new trailer. Have you considered going with a Reese Steadi-Flex system like part # RP66559? The frame brackets would fit around a trailer frame up to 6 inches tall. The weight distribution component would be as effective as the standard chain suspended model. The...

  • Recommended Weight Distribution/Sway Control for 2000 lb Scamp TT Towed By Jeep Wrangler Unlimited
    If the tongue weight of your Scamp plus the weight of any cargo carried in the cargo area of your Jeep behind the rear axle is less than 400 lbs (which it should be), I'd recommend the Reese Steadi-Flex Weight Distribution Kit, part # 66557. This kit is compatible with smaller trailers with tongue weights up to 400 lbs. In addition to the weight distribution component, the integrated sway control system will greatly reduce trailer sway. The kit includes the weight distributing shank, but...

This includes the total loaded tongue weight of your trailer and any cargo behind the rear axle of your 2016 Honda Odyssey that is towing it. I've attached an article to assist.

  • Recommended Weight Distribution System for Prowler Lynx Trailer with 360 Pounds of Tongue Weight
    If the 360 pounds of tongue weight is with the trailer loaded and ready to tow then I suggest the Reese Steadi-Flex # RP66558. It's rated from 400 to 600 pounds tongue weight and you'll fall right in the middle. The Steadi-Flex uses automotive style friction pads for sway control and doesn't use chains. You'll need a hitch ball with a 1 inch shank. Use # 63845 for a 2 inch ball or # 63847 for a 2-5/16 inch ball. If your trailer will be heavier when you're towing it and you need a...

  • Weight Distribution/Sway Control for a Ford Expedition and Keystone Springdale 189FL Travel Trailer
    The length of the trailer should not be an issue for you so I would not worry about that. Anytime the trailer weighs at least 50 percent of the towing vehicle when loaded and ready to tow using weight distribution is a good idea and the use of sway control will be beneficial as well. Big trucks passing or a cross wind on a highway can cause sway so it is better to be prepared for the inevitable rather than wishing you had sway control. There are a couple of weighs you can determine the...

  • Weight Distribution for a 2010 Chevy Silverado Towing a 5,100 Pound Travel Trailer
    That 350 pound tongue weight is likely the dry tongue weight. If the gross trailer weight is 5,100 pounds when loaded and ready to tow then the tongue weight would be 510 to 765 pounds (10 to 15 percent of he gross trailer weight). Then to that you would add the weight of anything carried in the bed behind the rear axle of the 2010 Chevy Silverado. The Fastway e2 system # FA94-00-0800 is rated for 400 to 800 pounds tongue weight so it covers the range above. You would also need ball...

  • Is a Weight Distribution Needed to Tow a 2015 Forest River Wolf Pup 16BHS by a 2013 Toyota 4Runner
    When a trailer weighs more than 50 percent of the tow vehicle's weight, we recommend using a weight distribution system. Also, sway control is a good idea, especially when towing with a midsize SUV. To choose a weight distribution system you will need to go by the total tongue weight of the towing set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle. Keep...

  • Is Weight Distribution Needed to Tow 6 x 10 Enclosed Tandem Axle Trailer w/ 7000 lb GVWR
    Anytime the weight of the trailer exceeds half the weight of its tow vehicle, using weight distribution is recommended. If you'll be towing frequently on the highway, the large cross section of the side of the trailer will make it susceptible to trailer sway caused by crosswinds and turbulence caused by passing and oncoming traffic. Because of this, I'd recommend you use the properly rated weight distribution system that provides a sway control component. To choose a weight distribution...

  • Recommended Weight Distribution and Brake Controller for 2013 Ford Flex Towing a TrailManor 3023
    To actuate the brakes on your Trailmanor camper, you would indeed need to install a brake controller. If the factory tow package on your Flex includes the OEM 7-way on the back bumper, the install would be plug-and-play, using the # 22292 Brake Controller Wiring Adapter. The wiring adapter would plug into the connector located under the dash pretty much directly below the steering column as shown in the photos I have edited for you. You can't go wrong with the Tekonsha Prodigy P2, part...

This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well.
