Note: Dual-cam sway control cannot be used with surge-type trailer brakes and is designed for Class III and Class IV hitches only. Should not be used with aluminum trailer frames.
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.
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.
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.
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.
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.

This hitch is much easier to set up, hook up and unhook than the hitch it replaced!
I have been around Reese Hitches for 50+ years. They are hard to beat!
Reese RP 66073, install on a 2017 GMC Sierra 1500. Used a drop shank because my truck (stock) hitch sits at 19”. Bought this product for a 7’X18’ V-nose trailer, system has a “standard” neck and this system is essentially perfect, had concerns at first. System is understandably overkill at first thought. I plan on pulling in the neighborhood of 9000lb from the coast of GA to Colorado Springs. I did not want to revisit this later on or part way through my trip! So getting this system should prevent any of the sway and weight sag during my haul. First day of install, system seems to work very well! Had concerns about the trunnions staying on at full turn but a full day of in town driving with and without load and zero issues. My setup is not a “forget it’s back there” configuration but a noticeable difference in pulling quality and stability overall! Finding something in the realm of 450’ pounds to torque the hitch ball is hard to do unless your in a specialty field. An install video online claims the rivet helicoils are 9/16, the system I received calls for an 11/16 hole for the helicoils. Local hardware stores skip right over 11/16 so if your at a lowes or the like, you will have to go with a unibit if this is the route you choose to take be very careful because going to the 11/16 setting will make for a loose fit for the rivets!! If you have the option I would suggest a 5/8” bit and file to get that snug fit that is required to ensure engagement on closed frame trailers! Other than that install was relatively painless. Lots of pulling and tightening if your having to install this manually!!
Made a huge difference in how the travel trailer handled crosswinds and passing larger trucks. Great recommendation!
The hitch itself is great. Took some time to dial it in. My trailer sits 28” high the Instructions only go up to 26”. So it took some time to get it to work. But once I got it dialed in everything else was easy.
This is one of the best hitches I've used. We took a trailer to Burning Man last year, traveling 2100 miles each way from Florida. Up hills, down hills, 6% grades and all. If a truck passing managed a bit of a sway in our 21' trailer, touching the trailer brakes, using the brake controller, set it back in line.
Set the trailer level and it works great!
I really like this hitch. NO trailer sway at all. Easy hook-up. I appreciate E-Trailer for their help in selecting the best hitch for my Rv trailer. Thanks!
We just returned from our first trip from Oregon to Montana. It was extremely windy and gusty both ways. This hitch is amazing. the wind and passing trucks never once caused the trailer to sway. It sometimes caused the trailer and SUV to move sideways slightly but always as a unit and always kept the trailer in a straight line with the SUV. It is easy to hook up. I recommend it.
A little noisy, but excellent control of trailer; fully adjustable
What a great company to work with. I had some trouble determining which hitch I needed. One phone call and they explained everything I needed to know. I have already made more purchases from etrailer.
Thanks guys,
Received my order in record time. Everything was well packaged and arrived in good condition. The assistance and recommendations I received were very helpful.
I have ordered numerous items previously from etrailer and have always been well satisfied with the products and the price. The etrailer folks are my choices for trailering parts and supplies.
Excellent customer service, great product. I can't imagine driving down the road without it.

Thanks for following up. Im still using the product without any issues whatsoever. We are getting ready to take a trip up into the mountains of NC and wouldnt want to haul the camper without it.
It works great. Easy to hook up and unh ook.

Better Price than my normal distributor and they had it in stock. quick delivery. will order again and again!
Very good service and excellent product.
Our family has been using the Reese Dual-Cam sway control (which comes with the Strait-Line WD setup) for over 20 years. The sway control arms, which bolt to the trailer A-frame, have cam arms which ride in the "saddles" on the ends of the WD bars. If set up right on installation, about the only time you would experience enough sway to give you "white knuckles" is when you are driving in a tornado! (& if that happens, GOOD LUCK and GOD BLESS!) The Hensley hitch is probably better (have never owned one), but the Reese Strait-Line is close to $2,000 cheaper, and none of our family has ever felt like we had a need for a hitch/sway control setup more expensive or better than the Reese, and most of us pull some really long and heavy conventional travel trailers. High crosswinds will move the entire rig sideways, but the trailer stays centered behind the truck. The "bow wave" of 18-wheelers overtaking us at a high rate of speed on multi-lane highways will push the rear of the trailer sideways as the bow wave passes. But no steering correction is needed. The additional couple of hundred pounds of pressure put on the WD bars when the trailer moves sideways and causes the sway control cams to move out of their "saddles" pushes the sway arm cams right back down into their "saddles" on the end of the WD bars, which, if the hitch was adjusted right on installation, means that the trailer is once again centered directly behind the tow vehicle. The Strait-Line can probably be beat, but we're never going to spend an extra $2000 to find out. If you have any control problems with the Strait-Line, it is either not set up correctly, or the wind is such that you shouldn't be towing anything, anyway. Even a Hensley hitch can't keep the entire combination of truck/trailer from being pushed sideways by very strong winds, nor can a 5th wheel hitch, because I've seen 5th wheels lying on their sides more than once, and during my working career I pulled high-profile or gooseneck heavy equipment trailers all the time. There are times when you just really shouldn't be towing large travel trailers, or any high-profile trailer.
I used this for the first time Pulling a 22 foot travel trailer with a Jeep Gladiator. I hit high winds 20+ gust to 40, heavy rain. I have towed thousands of miles and was ready for anything NO Sway at all felt solid I had people tell me I could buy a cheaper hitch YOU GET WHAT YOU PAY FOR
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.
I added this hitch setup to a 2023 F250 - 2023 Hawk horse trailer with tack room and I could not be happier. It allows the truck to maintain its proper ride height and eliminates all the minor steering corrections needed when driving at highway speeds on less than perfect roads. Proper setup is key and takes time but the outcome is well worth the time and money investment. This is the 2nd straight line set up I have had on my vehicles for horse trailer towing - first was for an Expedetion with a smaller trailer which provided me with a decade of confident trailering.
Installed this on a 2016 Silverado 1500 2wd dbl cab pulling a 2016 northland 30ft travel trailer. I was having the typical sway issues with crosswinds and passing big rigs etc. I am very pleased that this hitch solved the problem. Good quality product. I installed it myself and I had to buy about $100 in larger wrenches and a good quality step drill bit.
Awesome weight hitch! I pull a 28" camper with this hitch and its really nice not having to stop and break down the hitch before backing up the camper. I have about 3k miles on this setup and absolutely love it. Its also easier to store when not in use because the chains stay attached to the cams on the a frame of the trailer and not attached to the bars. So the bars arent as heavy. Thanks again etrailer
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.
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.

This Reese hitch is far superior than the one it replaced! Husky Center LineEasier to make running adjustments for conditions and loading of the trailer as well.
