Why would I buy this?

  • Because it doesn't just rely on tension to control sway, you won't get a really rigid ride
  • Tends to track better during turns and swerves than 4-point systems
  • You can easily switch out spring bars if you get a lighter or heavier trailer - no need to buy a new setup

Why wouldn't I buy this?

  • Premium features carry a premium price tag
  • Bars popping in and out of cams can create a lot of noise, especially when turning
Featuring dual-cam sway control, this weight-distribution system includes an adjustable shank and flexible, powder coated steel, trunnion spring bars to create a level ride for both your trailer and your tow vehicle.

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.


Serrated Washer System

Unique Features of Reese Strait-Line Weight Distribution

The easy-to-use, serrated washers on the Reese Strait-Line system make adjusting the tilt of the weight-distribution head a snap. This is a huge improvement over the standard pin-and-washer method, which involves piling washers - one on top of another - onto a difficult-to-access pin. The serrated-washer system lets you easily loosen, adjust and tighten a single washer and nut on either side of the head for simple, secure positioning.



The trunnion spring bars of the Strait-Line 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, ensuring a smooth, controlled ride for both your tow vehicle and your trailer. These specially designed bars have rounded, hooked ends, making them the only kind of spring bars that can function with Reese's active-style, dual-cam sway control.


Weight Distributing Hitch

Dual-Cam Sway Control

Reese's dual-cam sway-control system stops trailer sway before it begins. This is a significant improvement over traditional friction-style controls, which help to correct sway only after it has already begun. This specially designed system uses unique sliding devices called "cams" to suspend the spring bars of your weight-distribution system. One end of a cam bolts onto your trailer's frame, and the other end attaches to the lift bracket via the lift chain. The rounded, hooked ends of the spring bars then sit in these cams. The controlled placement of the spring bars keeps your system secure while still allowing enough movement for free, easy interaction between your trailer and your tow vehicle.



Dual-Cam Sway Control Turning

During basic, straight-line towing, the cams lock in place and hold the trailer steady by applying constant, consistent pressure to both sides. This keeps the trailer from swaying in crosswinds. When you go into a turn, the cams unlock and slide to allow a controlled, full-radius maneuver. If you swerve suddenly, the cams will give to accommodate the movement while still working to obtain a straight angle, thereby maintaining control of the trailer.

Video Transcript for Reese Weight Distribution - WD With Sway Control - RP66083 Review

Today well be removing part number RP66083. This is the Reese Straight Line Weight Distribution System with Sway Control. It is going to be a Trunnion Bar Design and its going to include the shank as well as all necessary hardware including your 5/8th inch pin that comes with a clip. Now this system is going to evenly distribute the weight over the axles of the towed vehicle and trailer for stability and control and thats just going to help create a more level ride for both the towed vehicle and the trailer. Its going to feature the automatically self-adjusting, self-centering sway control thats going to work in a variety of situations. The sway control system is basically this system right here. Youre going to have one on each side of the system so youre going to have one on each side of your trailer frame.

Now in straight line movement, the cams are going to lock in position to hold the trailer steady despite crosswinds. When you go around corners, the cams automatically unlock and slide to allow full radius turns and then when you have those situations when you cant help but have to swerve, the cams are going to seek a straight line angle to help stabilize your trailer. Now the sway control is going to bolt onto the A-frame trailer tongue and attach the lift brackets using the chains. When you get the sway control system, you can see that the Trunnion Bar sits over the portion down there. It just lays on top of there. Then you have this bracket that attaches and then with a little U bolt, its going to hold the chain on there and its going to attach to the lift bracket and the lift bracket also attaches to your trailer frame. The good thing about this system is you dont have any large U bolts or platforms to interfere with frame-mounted items such as gas tanks, tool boxes or generators.

The Trunnion Bars are hot rolled and tapered for superior strength and flexibility, so the bars will flex appropriately over uneven terrain for a nice controlled even ride and then the sway control cams are going to provide attachment points for the spring bars. Again, theyre going to attach using those chains. The head assembly and the adjustable shank are included. The head assembly is going to feature a forged raised ball platform so thats going to eliminate the need for a raised hitch ball. Then here on the shank, its going to feature a nice solid steel shank powder coated finish so this is going to stand up really well against rust and corrosion. The spring bar tension is adjustable.

All you have to do is switch the links and the chains where it connects to the lift brackets. Thats going to allow you to fine tune your system. Another great feature is that you can easily get the tilt that you desire with the serrated washer design which you have one on each side. The serrated washers have little teeth in them that dig into the teeth or the grooves on the head assembly. Thats going to allow the head to get the tilt that you need for your particular application. Its also going to eliminate the need to have to pile on washer after washer to get the desired tilt that you need again for your towing application. The system is going to include the sway control cams, the head assembly, the adjustable shank, the lift brackets, the spring bars.

Youre going to get the lift chains. Youre going to get the pin and clip and youre going to get all necessary hardware. Now theres a few things in here that you dont necessarily see in our description that youre going to get. Youre going to get a snap up handle. This is basically to be used as a leverage device. Once you get the chains on the lift brackets, sometimes its really hard because of the tension to get the lift bracket back up into position, so the snap up handle allows you to gain some leverage, put it over that portion there and then youre going to be able to push it up into position. Once you have it up into position, you can easily attach and secure using the included pins. Its going to be same for each lift bracket. Its also going to come in handy to bring the bar of the bracket back down. That way you can remove the chains or you can adjust the links in the chains to fine tune your system. The hitch ball is also going to be sold separately. Now this one does require a threaded shank with an inch and a quarter diameter. It is going to come with a reducer sleeve. That way you can use a threaded shank with an inch diameter so that reduces it from inch and a quarter down to an inch. Thats optional to use, but keep in mind that if you do get a hitch ball with an inch shank diameter that that will only work with a reducer sleeve in the appropriate slot. Youre also going to get the shim. This is provided. Its designed to take out any gap or slack that you may have between the shank of this portion right here and the bracket of the weight distribution head. It would slide in there again to take out any slack. Its got the two holes in it. That way you can run the larger bolts through there and get it nice and secured. Its going to offer a tongue weight of 400 to 800 pounds with a gross towing weight of 10,000 pounds. The shank is designed to fit a 2 inch x 2 inch trailer hitch receiver that is rated for use with weight distribution systems. Now the lift brackets, they simply just go over the trailer frame, this portion here, and its got the set bolt on the back. You just tighten that up. Its going to apply pressure to the inside portion of your frame of the trailer and its going to hold the bracket in place. This is going to approximately take up about 5-1/2 inches of space along your trailer frame and it will not fit trailer frames wider than 2-1/2 inches. Youre going to position the lift brackets about 30 inches back from the hitch ball so youll do that measurement on each side to make sure that you an accurate installation of the life brackets. Now the shank length, were going to take a closer look at that real quick. You can see there that it has two different pinholes. It has one thats set a little bit further back, thats where I have the included the 5/8th inch pin installed. Then it has one thats set a little bit more forward. If we take a measurement from the center of the hitch ball back to that closest pinhole location, thats going to give us a measurement of about 14 inches and then to the further back pinhole location, its going to measure about 15 inches. The total height adjustment that youre going to have along the shank is going to measure 5-1/4 inches. The maximum rise that youre going to be able to get out of this system is going to be 6-1/2 inches and the maximum drop is going to be inch and a quarter. Thats measuring from the top of the hitch receiver opening to the ball platform. Everything is a steel construction. It has a really nice black powder coat finish on it so its going to stand up really well against rusting and corrosion and its going to provide a really long life for everyday use. Its a great system to have. Again, its all about safety and creating a more level ride for both the tow vehicle and the trailer. Thats going to do it for our review of part number RP60083. This is the Straight Line Weight Distribution System from Reese. .

I had this hitch installed at a local RV specialist shop as I didn't have access to a large enough flat and level area. The cost was about $225. When I picked up the truck and trailer for a test drive, the trailer tracked true behind the truck and I never felt any sway. The load leveling feature helped keep the truck level and I always felt I was in complete control. The only down side to this product is the noise it makes when taking sharp turns. The metallic popping noise are scary at first but I was expecting them. Overall I am very pleased with the performance of this hitch and would recommend it. 281068

The hitch worked wonderful. I was scheduled to have it installed by others but when they saw the unit they got scared, I think. So, having read and re-read the instructions myself by this time, I decided to go it myself. It took all of 4 hours and the following day we left on a five week trip to the northwest US. It performed really well. We had taken two shorter trips without it and I can really feel the difference it makes in windy conditions and weight distribution. 216549

Works great on a older 28 ft. 6000lb. restored Airstream with a F150 4x4 with anti sway electronics. Without we could only go about 55 mph and the trailer would sway. The truck would warn us to slow down. The install was a bit complex we were not too sure of the angle of the hitch but we followed directions and it works. We traveled about 6k miles on two trips. It stopped the sway even at 70mph . Many a giant truck flew by at 80+ it started to sway but the bars prevented it. Backing and tight turns are no problem. Adjusting the chains require some work and disconnecting, reconnecting a pain. would highly recommend to any one . 287015

I purchased my second one in 2018 after having this system on my previous trailer. I love the function and how well my travel trailer is balanced with pull and weight distribution. The biggest change is in a tubular installation. The "press in" nuts have no tolerance for drill hole sizing error. I use the drill bit sizes and methods describe by the manufacturer. Yet, the nut would spin free during assembly. I had to use a creative solution just to get my system installed. I gave 4 Stars instead of 5 due to installation is not user friendly for a tube frame trailer. 661155

I think the setup is great. The installation was a little tricky since I’ve never installed anything like it before, but there are plenty of installation videos out there to watch first (and to reference during install). When I’m towing I sometimes forget my 30’ camper is back there. As far as sway, I have get to be effected by any. I would recommend this hitch and I would buy it again if needed. 644262

Installed it to take 30 ft Springdale trailer to Yellowstone from Pa and back, best trip with camper in 10 yrs we have owned it. No sway or sag. Pulled with 2005 2500 Suburban. Makes loud creaking when turning sharp, but i've heard they all do. 608555


Comments
The creaking noise you describe is caused by the spring bars sliding over the sway control cams, and is unfortunately unavoidable. As you mention, all weight distribution systems that depend on some kind of friction to provide the sway control function are going to make some kind of noise.

This Reese weight distribution and sway control unit is actually my second one. My experience installing the unit and then towing a 34 foot travel trailer with the first one was excellent. When I purchased a large enclosed car hauler, it was a "no brainer" to order a second one. The installation took approximately 4 hours although it could take less time if you aren't OCD like me. The trailer tows beautiful and etrailer has been very nice to work with... 476947

    The key to purchasing the correct weight distribution system and sway control is choosing a system that is compatible with the tongue weight of your trailer. So it is important to know the tongue weight of your trailer when it is fully loaded and ready to tow. With that being said, I have attached an article on determining trailer tongue weight for you to review. If the tongue weight of your trailer is greater or less than the tongue weight range on your weight distribution system,...

  • Weight Distribution System Recommendation for 700 lbs Tongue Weight
    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 tongue weight for you to check out as well. You will want the loaded tongue weight of your setup to fall right in the middle of the tongue weight range of the system you use. If you think the highest you would...

  • Which is Better Equalizer or Strait Line Weight Distribution
    I recommend the Strait Line systems the highest. They have the most advanced sway control that works to fight sway before it even starts unlike the Equalizer that basically tries to minimize it as it's happening. Also, because the tongue weight ranges of the Strait Line systems are just easier to recommend. The Equalizer ranges are pretty small whereas the Strait Lines seem to be just wide enough to make the most sense. The Trunnion bars of the part # RP66083 are considered more heavy...

  • Recommended Weight Distribution System for Towing an R-Pod 190 with a 2019 GMC Canyon
    I highly recommend using the Reese Strait-Line # RP66083 for your R-Pod 190 because this is one of the few systems that fights sway before it starts instead of correcting it after it already starts. This gives you a much better ride quality and since this uses chains it will be a little quieter than a system that mounts solely with brackets. You just need a hitch ball like the 2" # A-90 or the 2-5/16" # 19286 to complete your towing setup. The lift brackets need to be mounted about 30"...

  • Weight Distribution System Recommendation for 500 lbs Tongue Weight
    Between the three listed the part # FA94-00-0600 is the best for a loaded tongue weight of 540 lbs give or take. That being said the best option is the part # RP66083 as it has a tongue weight range that would work perfectly as well but features sway control that works to fight sway before it starts. For a 2 inch ball you would want part # A-90 and for a 2-5/16 inch ball # 19286.

  • Replacement Parts for Reese Strait-Line Weight Distribution System
    We do carry replacement parts for weight distribution systems like the excellent Reese Straight-Line systems such as # RP66083. It sounds like you have everything except the trunnion spring bars and the shank, which is what fits into your hitch receiver and holds the head assembly. I linked our page for Reese trunnion spring bars. The type you need has a bend in the trailer end, such as # RP58369. You will want to select two bars based on your fully-loaded trailer's actual measured tongue...

    The best weight distribution system for your travel trailer and 2016 Nissan Pathfinder is the Strait-Line Weight Distribution System # RP66083.

  • How To Determine If A Weight Distribution System is Needed On a Trailer
    Typically we have a couple indicators that help you figure out if you are in need of a weight distribution hitch. 1-Your trailer weight (GTW) is more than 50 percent of your vehicle's weight (GVWR) 2-The rear of your tow vehicle sags when the trailer is hooked up 3-You experience trailer sway 4-Your tow vehicle's headlights point upward 5-You find it difficult to steer or stop your rig 6-You want to tow to the highest capacity allowed by your vehicle's trailer hitch If you find...

  • Weight Distribution System Recommendation for 6,500 lb Trailer
    Getting your tongue weight to be 10 to 15 percent of the total trailer weight will have the greatest impact in reducing the sway of the setup. Also having the trailer as level as possible will help too. For a trailer that weigh 6,500 lbs the Reese Strait Line system part # RP66083 is going to be the best option as it has a tongue weight range of 400-800 lbs and features the dual cams you are interested in which fight to prevent sway before it starts. For a 2 inch ball you would want...

  • Recommending a Weight Distribution System for a 2007 Chevy Trailblazer
    By tongue weight, I assume you mean gross trailer weight (GTW), which is the weight of your 2007 Stampede when it is fully loaded. Trailer tongue weight is a different measurement, and usually between 10 and 15 percent of your GTW. Total tongue weight is the most important measurement to have when it comes to choosing the correct weight distribution system, and will be the tongue weight of your fully loaded and ready to tow Stampede plus the weight of any cargo you have behind the rear...

  • Weight Distribution for a 2005 Chevy Tahoe and Dutchmen Aerolite 195QB Travel Trailer
    When choosing a weight distribution system you will need to go by the tongue weight of the trailer when loaded and ready to tow plus the weight of anything loaded behind the rear axle of the tow vehicle.I did some research and found that on a 2012 Dutchmen Aerolite 195QB the gross trailer weight is approximately 5,400 pounds. Tongue weight is typically 10 to 15 percent of gross trailer weight so we are looking at 540 to 810 pounds. If nothing is loaded behind the rear axle on the Tahoe...

  • Recommended Dual Cam Weight Distribution System for 2019 Chevy Silverado 1500 Towing 7K Trailer
    I'm happy to clear all this up for you, and let's start with the dual cam systems compared to the friction-control systems like your Equal-i-zer. While neither are going to completely and totally prevent all sway, you are right that the dual cam systems will be a bit less "stiff" as you put it. The reason for that is pretty simple - friction systems rely on force to get the trailer back in line once a bit of sway begins while the cam system of the Strait-Line is consistently applying pressure...

  • Does Shortening Chain of Weight Distribution Chain Hangers Reduce Suspension Sag
    You are correct. If you shorten the length of the chain between the spring bars and the frame hangers you will apply more spring bar tension which would remove even more sag from the rear suspension. For more info on installing and setting up the Strait Line weight distribution systems check out the video I attached that shows the entire process.

  • Comparing Weight Distribution Systems that Use Chains Versus No Chains
    For a weight distribution system, there are always exceptions,but in general the systems with only bars and chains do not have sway control. They are adjustable in tension for different weight, but are a little more work. The bar systems whether trunnion or round bar, usually have an element of sway control and are easier to use. My favorite system is a hybrid and is the Reese Straight-Line like # RP66083. Systems are available in different weight ratings and you want to make sure...
