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.

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.
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 .
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.

This hitch continued to work great with my travel trailer through the 6 months after this review. I traded it away at that point, but retained the hitch. Looking for a non-travel trailer to add it to at this point due to its tremendous reliability and performance. I still stand behind this hitch and continue to recommend it to my friends.
Just returned from a 4400 mile trip pulling our travel trailer and it drove so nice! Almost zero sway and I installed it myself…
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.

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.
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.

Flawlessly.Just returned from a 5-week, 5,600 mile trip. No problems with it.
Strait-Line Weight Distribution System w/ Sway Control - Trunnion Bar - 8,000 lbs GTW, 800 lbs TW
We love this hitch. You can forget the RV is back there. We are pulling a 16" Wolf Pup with our Gladiator.
Bought this hitch to use on a Jayco toy hauler at a dealers recommendation who sold several different types of load distribution/stabilizer products. Worked great so I bought another one for our new North Trail which is same size but 1/2 the weight. Only this time I installed it myself. Support from etrailer was excellent. They know their product. I actually ordered the wrong weight bars, and another part was missing and we had a trip scheduled! They got us the parts ASAP and we were ready to go with time to spare. One point of caution: When installing the ball, it requires 400 lbs of torque. I took this to a truck repair shop and did it for me free in just a minute.
I'm extremely impressed with ETrailer. The order was processed, shipped and delivered within 4 days...if it hadn't been for the weekend, it would have been sooner. The free shipping was a plus! I plan to install the system this week and will share pictures when finished. I would not hesitate to recommend ETrailer! Thank you!

Very, very well! I would not hesitate to recommend this product. Im still impressed by the service given by E trailers.
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.
This is definitely one of the very best weight distribution/sway control systems on the market. The travel trailer moves smoothly down the road with no wandering whatsoever. Large tractor trailers barely move the travel trailer as they pass by. I've taken several trips since buying this system and it consistently preforms very well. It's a great system I highly recommend this product.
It’s easy to hitch up and distributes the weight well but does not do much for sway control for my single axle 3500lb trailer.
Took me about 8 hours to get it setup perfectly, but it was well worth the time spent. I pull a 20 foot v-nose trailer behind a 2014 F150 5.0. Its about 6,000 lbs with my race car in it. It used to sway a bit in the wind and not track great. This hitch really makes driving down the highway easier. No sway now, and tracks much better. I think it is well worth the time and money and would recommend this hitch to anyone.
Wish we would have purchased this sooner. Makes pull the camper much easier tans and gives us a feeling of being in control instead of the camper in control.
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...
Working great
Easy to follow instructions.
Quality product.
Haven't towed TT w/ setup as of this date.

Works great, fairly easy pactical removal when going of road. No problems.
The new weight distribution hitch exceeded my expectations
Pricing was excellent,
Customer service was second to none!
Have one on my truck works very good. This order is for my daughters truck feel the sway bars make towing a lot safer for someone new to trailer towing.
Install the reese after fighting with a blue ox hitch.
The reese worked well on my 8k , 3 month trip from Maine to California.
Have not opened up the two packages yet. My friend has one exactly like this one and he likes it very much and said he is getting no sway from Florida to Michigan. I believe we will be very happy with this hitch.
I told them the year of my truck the reciver was to short they said buy another after I spent 700 plus I don’t think so

Knowing the height difference between the towed vehicle and the trailer is key in making sure the included WD shank will work for you. I have included a few articles below that would be helpful in obtaining this information.
The equalizer hitch arrived. It is really a heavy duty piece. unfortunately we will not get to road test it for a few more weeks when our new trailer arrives.
Great product. Not too bad of an install. Works great. Thanks etrailer.com
Great product. Fast Shipping. Night and day difference from my previous trunnion bar friction style hitch.
