Is this right for you? Product Expert Lindsey S says:

Yes, if you:

  • Hate the tight, rigid ride you get with other systems that have built-in sway control
  • Might need to upgrade to a heavier trailer down the line and don't want to have buy a completely new hitch
  • Have a lighter weight trailer with 200 lbs – 600 lbs of tongue weight that often veers out of line with your vehicle

No, if you:

  • Don’t have a lot of space to work with on your trailer frame, or if the frame is thicker than 2-1/2”
  • Have a boat trailer with surge brakes or an aluminum frame
  • Hate noise - the bars popping in and out of the cams can create a racket, especially during turns
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. Fits 2" trailer hitches. Lowest Prices for the best weight distribution hitch from Reese.

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.

I tow a 2800 lb travel trailer (loaded) with a 2015 Kia Sedona. Everyone told me this hitch was overkill but that’s what I wanted. It gives you so much control and I believe makes towing much safer for everyone. It is a little harder to install but it’s worth the extra time. etrailer was great throughout the whole buying process.

I have a 21 foot travel trailer that I pull with a Nissan X-Terra. Before getting the Strait-Line Weight Dist. System, the back of the X-Terra and the front of the trailer would be too low, creating a "V" at the hitch connection. In addition, out on the highway, the trailer would sway, particularly on the down hills, and at times would get so intense I was afraid the sideways energy created would force me into oncoming traffic or off the road to the right. After installing the Strait-Line system, the X-Terra and trailer are leveled out and the sway problem has been completely eliminated. I could not be happier with the results. I would recommend this product to anyone having these problems. Do your research to make sure you get the proper size for the unit you are pulling.


Comments
A couple of months ago I purchased a 2017 Ford F150 with the built in sway control. The new truck pulls the trailer much more easily than my Nissan X-terra did. Although hooking up the trailer to just the ball hitch on the new truck is much easier than having to use the Strait-Line Weight Dist. System, I do find that the trucks built-in sway control, although adequate, does not work as well as the Strait-Line system does. The trucks built-in system can get overwhelmed by excessive sway and must rely on an automatic deceleration system to correct and control the sway, which can at times be a bit of a challenge until you get comfortable with it.

Company Rep ( Tommy C) was amazingly helpful in doing rapid research with Reese company and determining that my existing system although still functional contained obsolete parts and should be replaced to accommodate second trailer needs. New pets order was immediate and I received all necessary parts on 3rd day from order. Exceptional! Now a design complaint regarding mounting the Reese Sway Control brackets to trailer frame tube (2"x6"-1/8" ) with press in "nut rivets". This frame is not adequately thick enough to accept this attachment procedure unless these items are welded in place to keep them from "stripping out". Holes in frame were correctly drilled per instruction. My machine shop, one of the most respected in Illinois, that this is a very common situation which can only be remedied by a skied welder. This is something that Reese and you should address. Hope this will assist others. Thanks for your excellent service.

System works perfectly, as expected. Thank you for following up on this issue.

New to the camping world but did my research on this Reese straight line hitch and just pulled 780 miles to Maine. I felt comfortable and confident in knowing that my first experience would not be a disaster . etrailer was awesome in our decision making because I was able to bounce questions off them (Maranda) to make our best fit and I couldn’t be more happy. The installation can be done by a competent person but buy good drill bits first and have your C clamps ready . I think they show 3 different drill bits to use with precise drilling instructions. Ok but did scratch my head a couple times as the directions could be more clear.

Purchased this to tow our MicroMini Winnebago 1700BH with our 2012 GMC Acadia with factory towing package. My father has towed with these for years and swears by them. I know why now. Wind, passing 18 wheelers, whatever - these things keep our ride level and straight. I like having the sway control built into the equalizer bars, and what I would call the "active" sway control. When these get out of the stirrups they actually force themselves back with the pressure the misalignment causes as opposed to the "friction brake" style. Well worth the money.



- RP66082
by:

Good system design and solid. Prevents sway, side to side, up and down because of the shape of the arms' end, the free moving holder and the chain link length that is adjustable. You can see at the turns how the system pushes back trying to straighten the convoy. And even backing up is fine, others cannot do backup. It will lift the truck to be even both the front and the back. I recommend. Best in class

after one year of use this product has held up great, some surface rust in areas, but with the abuse it takes that is to be expected. Id recommend this product to others. Ive sold the sway bars as they didnt fit on my pop up camper, but the weight dist works great.

Review from a similar Strait-Line in Weight Distribution Hitch


The product was not only a perfect physical fit for my truck and travel trailer, but it it works so well I no longer drive with white knuckles. The etrailer support team worked with me to figure out my real needs versus my preciously rookie "wants" which were somewhat uninformed wants. My Trunion Bar WD Hitch with Optional sway control makes ZERO noise in use or backing up, nor does it impart any felt knuckling.


Comments
Absolutely the best working hitch ever. No noise, clacking and knuckling like friction hitches. The sway control is amazing.

Review from a similar Strait-Line in Weight Distribution Hitch


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.

No problems, hitch still performs as I described in my write up a year ago.

This is simply a very good hitch. Installation instructions produced a completely flat tow when the trailer settles on the truck. My rig is sway free there's no extra up and down movement. The hitch is quiet going forward and backwards. Just really pleased.

Review from a similar Strait-Line in Weight Distribution Hitch


I use this to pull a 3500lb travel trailer behind my 2007 BMW X3. We just completed a 4000 mile road trip with this hitch, traveling on every difficult windy curvy hilly mountain and coastal road from San Diego to Vancouver and back. The PROS: Easy to install, attach and detach. It distributed the weight well, and we had no problems with sway. The CON: It moans and groans on turns like an old man that forgot to take his pain meds. Even when it’s been lubricated.


Comments
The noise you describe is a function of the metal on metal contact that provides the anti-sway component of the system. Because lubricating the contact points would defeat the sway control function, the noise is for the most point unavoidable.

Review from a similar Strait-Line in Weight Distribution Hitch


We bought a very large travel trailer after having owned on before. With the first camper I eventually ended up with a Reese cam sway control as the only way to control sway in Kansas cross winds. I made the mistake with our new camper of following the recommendation of the dealer on a hitch for the new camper (36ft 9600lbs unloaded). It was really just a variation of equalizer bars and man what a mistaKe that was! I looked for the Reese cam system but wasnt finding it in my searches - then realized they changed the name to the Strait-line. This thing is amazing! What a difference in the wind. And you back up without doing anything to the hitch which I guess can be an issue with 4-points. When setting it up follow the instructions to the letter, and always think “keep thongs symmetrical.” It wont disappoint. Love it.

Review from a similar Strait-Line in Weight Distribution Hitch


OK, I waited to write this review until I had an opportunity to really use this product. We just completed a 950 mile camping trip around Colorado. We went up and over mountains, around curves, and traveled in the interstate. All I can say is, WOW! I wish I had purchased this years ago. We pull a 7000# travel trailer with a new F150 EcoBoost. Before installing this we were pushed around in windy canyons, semis and dealt with sway descending the mountains. This product is the real deal. I can safely travel on the interstate at speeds up to 75 MPH thanks to this product.


Comments
I have a 33 TT towing with an ecoboost. I think the hitch I have is too week. My TT never gets loaded over 6,500 yet I still get a bad front end drift? I think its the WD I currently have. Does this hitch really solve that problem? My TV is a super crew lariat off road package with c rated tires
-- comment by: Josh - 08/08/2014

Weight distribution can help handling and steering when properly set up. This system also has an integrated sway control system also improves handling and stability. With your travel trailer loaded and ready to go, having about 650 pound of tongue weight, this system is rated appropriately for your needs. If you are experiencing too much front end sway you may need to make some adjustments to place more of the load on the front axle These adjustments can be made at the angle of the head. Please see your specific installation instructions for more details.

Review from a similar Strait-Line in Weight Distribution Hitch


I've been very happy with the system that we got, we put almost 7,000 miles on it in 2017 and it rode great. I added a secondary friction sway control to compliment the control provided by the leveling bars and cam assembly and over those miles it never felt uneasy. A couple of times we were in some pretty good cross winds and I would notice enough to put two hands on the wheel but the rest of the time it was almost easy to forget we were towing a 28' trailer. I'd definitely recommend spending a little time at your local Cat Scales to find out your specific truck / trailer and tongue weights, but this hitch and distribution assembly gave us the ability to tune the tongue weight into right where we wanted by the selection of the right link. The peace of mind the overall control that it provided going down the road is well worth it.

Review from a similar Strait-Line in Weight Distribution Hitch


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 .

The Reese Strait Line kit part # RP66082 would be a great option for you as it has a tongue weight range of 200-600 lbs which would be perfect for your trailer and then it also comes with the only sway control on the market designed 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.

  • Will Weight Distribution System Allow Honda Odyssey with Class III Hitch to Tow Camper
    You are correct that the weight of equipment loaded behind the tow vehicle's rear axle must be added to the tongue weight. The tongue weight is usually 10%-15% of the loaded trailer weight, plus the weight of this additional equipment. If we go with the upper end of this range and assume that your trailer will be loaded to its full capacity, 3,015 lbs, this gives us a tongue weight of 452 lbs. Without knowing the exact capacity of your hitch, it's difficult to say whether this will present...

  • Best Weight Distribution System with Sway Control for 2012 Nissan Xterra and 2012 Toyota 4Runner
    The only issue you might run into as far as compatibility between the two vehicles is that the rise/drop needed to tow the trailer level might be different on the Nissan and Toyota. I'm attaching an article on choosing a ball mount for you to check out. It explains how to determine the rise/drop between your hitch and coupler. If you'd like to send me the rise/drop measurements for your two vehicles, I'd be happy to make sure you have all the necessary components. The other thing to...

  • Weight Distribution Hitch for a 2017 Toyota Highlander
    Even with a weight distribution hitch, the maximum towing capacity of a 2017 Toyota Highlander would still be 5,000 lbs with a maximum tongue weight of 500 lbs; a weight distribution system would not change the amount of weight the vehicle would be able to tow. In order to choose the best weight distribution hitch, you will first need to know your total tongue weight. That weight is going to be the tongue weight of your fully loaded and ready to go trailer plus the weight of any cargo...

  • Weight Distribution Recommendation for a Honda Pilot Towing a 4,000 lb Trailer
    I really like the Strait Line weight distribution systems as they feature the only sway control that works to prevent sway before it starts. 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...

  • Mounting the Dual Cam Sway Control on a Low Clearance Pace American Journey Trailer
    I talked to my guy at Reese about your weight distribution setup and you can place the frame bracket of the Dual Cam sway control bracket further forward on your trailer frame. Technically your trailer has a standard coupler. I am guessing you went with the bottom-mount coupler because the bottom of the coupler is almost level with the bottom of your trailer frame. The 20-1/2 inch measurement is to give you an idea of where the sway control bracket will be mounted, but that distance can...

  • Recommended Weight Distribution System for Aliner Classic Camping Trailer
    For the weight capacity, you do not technically need a weight distribution system. However, due to the design of the trailer, I do recommend using a weight distribution system for the sway control features as the crosswinds or passing vehicles may create more sway than would be comfortable. For your 2015 Honda Odyssey, I recommend the Strait-Line Weight Distribution System w Sway Control # RP66082 for your application because it will be a fit for your trailer tongue weight and any...

  • Recommended Sway Control for Trailer weighing 2,000 to 3,000 lbs
    Sway can happen at any speed, but you are correct that it can be more of an issue at higher speeds.

I recommend the Reese Strait-Line Weight Distribution System w Sway Control # RP66082. This system will not only help distribute the weight of your trailer tongue as well as any cargo behind the rear axle of your towing...

  • Bolt Grade Used On Reese Weight Distribution Systems from Shank to Head
    The bolts used to hold the weight distribution shank to the head is grade 8 on the Strait-Line Weight Distribution System # RP66082. I went out into our showroom and snapped a pic of what the bolt head to show you that it is a grade 8. Basically, to determine what the grade is of a bolt you need to count the amount of markings on the bolt and then add 2 to determine the grade. So this bolt has 6 markings which means its a grade 8.

  • Weight Distribution Recommendation for a 2011 Toyota Tundra and Jayco Eagle Travel Trailer
    When choosing a weight distribution system you will go by the total tongue weight. This is calculated by taking the tongue weight of the trailer when loaded and ready to tow then adding the weight of anything loaded behind the rear axle of the vehicle. Ideally you want a system with a tongue weight capacity range that encompasses the total tongue weight or a max capacity that exceeds the total tongue weight. Tongue weight of a trailer is typically 10 to 15 percent of the gross trailer...
