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.

The best hitch for anti-sway! It kept everything in line! Even when gusts of wind would pitch trailer and send an F250 truck out of control into center divider! THANK GOD FOR THE FORD'S TRACTION CONTROL SYSTEM!! We sold the pull trailer and moved on to a 45' 5th wheel! What a difference. I will never own a pull trailer greater than 24ft ever again.
I purchased and set this up between my 2017 F250 diesel and a 12K, 37’ travel trailer. I use it in conjunction with the Gen-Y torsion hitch. The combination of these together is the most incredible tow solution I have ever had in place. My wife is happier to experience less load transfer back into the truck on bumpy roads and I am ecstatic to have much less to no white knuckle sway issues through the windy flats and as well as passing between semi trucks. This is a bolt on so I recommend having exactly the correct drill size and type available, as I used a step drill that reamed out one of the 4 holes initially. After speaking to the manufacturer, they said I could just bolt straight through the frame with a longer bolt and nut. The brackets are already formed to accommodate that option as well. In short, I will never tow with a different setup. Only down side is it tows so well that I forget sometimes the trailer is back there on long hauls. ;)
This is a super heavy hitch for a large heavy camper. Take your time setting up the sway control bars and it will reward you with probably the best performance that will be had with a heavy, long bumper pull trailer. The hitch is a little noisy during turns, but that doesn’t bother me. My F250 4x4 handles our 32’ Jayco toy hauler with no drama after finding the right chain tension. Very happy with the hitch. Thanks Lori at etrailer.
I've had this product installed for about a year. I race motorcycles and installed this on a 35' toy hauler that use at least once a month. Hooking it up to the truck is simple with the sway bars, and it helped to greatly reduce the sway travelling down the road. Toying something that large without a system like this is a safety issue, and I feel much better toying now with it on.
unbelievable hitch.....works amazing
Performing better than expected. No sway at all with 12,000 lb. trailer.
The package came on time and is complete. Good company.
Outstanding Company.
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
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.
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.
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 .
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
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.
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.
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!
Ordered same unit 9 years ago this one was for our brand new trailer. Just what I needed. Delivered so quickly very fast service
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.
