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.

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.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
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.

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

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.
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.
Pulled an 11,000 lbs enclosed trailer from Arizona to Rhode Island. Once I got the load adjusted, I didn’t have enough weight on the tongue, it worked well. I’ll buy it again and would recommend it.
I purchased the weighted distribution hitch a year ago and have towed my rv trailer on a dozen trips. It minimizes the sway from wind and being passed by semi trucks. Towing is much easier now. The installation directions are clear and there is a YouTube video to watch. I installed the weight distribution hitch myself, it took about 4 hours to install and adjust the cams. I would buy this again, worth the money.
I had experience with towing travel trailers before, but it had been a while. When we decided to buy a new trailer, the hitch setup the trailer dealer proposed just didn't seem right for the job. Doing some research on my own, I came across the etrailer.com site. From the information that was available on the site I was able to focus in on what I thought would be the best fit for my F-150 towing an 8,000 lb + trailer. When I called with questions, I was fortunate that I talked to Wayne--one of etrailer's product specialists. This was like talking to a trusted brother. We discussed a few different brands and the pros and cons; but in the end decided the Strait-Line RP66084 would be the best fit. After that conversation, I did some more research on my own and--besides discovering that Wayne's advice was fantastic and spot on--found that the Strait Line system proposed was top ranked. The features I was looking for: (1) Leveling (weight distribution) capabilities (2) Sway control (3) Safety (4) Tracking (holding the trailer steady behind you when taking curves (5) Ability to back up without having to get out of truck and manually release a brake bar and (6) simple enough to install for a shade tree mechanic. The Strait-Line fit the bill and I'm very appreciative that etrailer.com has experts--rather than sales-focused pushy people--to help you make the right decision. I've pulled my trailer with ease and the Strait-Line has lived up to every expectation. And etrailer.com's price was great and the shipping had it delivered sooner than expected. It's rare when you can say you are COMPLETELY SATISFIED with a product, service, quality, and price--but I can that about my purchase of the Strait-Line RP66084 from etrailer.com

Greattowed trailer through wind and hail on way to Floridasure glad I had this hitch setup!
Ordered same unit 9 years ago this one was for our brand new trailer. Just what I needed. Delivered so quickly very fast service
Works great just what we needed.
I can't vouch for the product as yet, because I haven't installed it. I can however comment on the service & etrailers excellent way of updating the progress of the transaction. It was very efficiently & fast. I ordered the hitch on Sunday night and UPS drove up in front of the house on Wednesday about 1:30 pm and delivered it. That is great service by any ones standards. I've read the instructions some & it looks like it will take some time to install this unit. There are a number of tools that are needed to accomplish the task & not all of them are in just everybody's tool box. (unless you are a heavy equipment mechanic) which my son-in-law is, so I had access to everything I needed. A friend also bought this hitch & purchased all the tools needed to do the job so I am all set to strike out and install the hitch, as soon as it takes a turn for the better weather wise. The hitch is a massive heavy duty unit that looks to be able to handle the job with ease. When I get it installed & use it awhile I will repost a review concerning it's use & installation info including the quirks & all the things needed to measure & drill, etc. to put it to use. I again want to thank etrailer for their attention to every detail of the transaction & the prompt service & almost miraculous delivery in such a short time right to my door & in a complete state. (nothing missing) it was very well packaged to stand up to the rigors of shipping.Kudos Etrailer...

After using this hitch for a year it has performed as well as I could have expected

Ive been using the Reese Straight-Line system since 2006, its the best performing distribution hitch Ive owned. I had a traditional round bar set up w friction sway control on my previous trailer. The straight-line gives you an extremely solid
The sway control worked OK when the hitch was new but after 8000 miles and as the hitch wore in, my 32 foot trailer became harder to control as the trailer mounted sway brackets developed flat spots on the rollers - the grinding noise which got worse as the hitch heated up from the vehicles exhaust has become unbearable. I have elected to order a different hitch / sway system which unfortunately is not sold by etrailer.

I have reached out to my contacts at Reese regarding your concerns about your Straight-Line weight distribution system and get the following information that I wanted to pass along you you: It is normal for the dual cam portion of the hitch to develop wear or flat spots on the rollers. The spring bars constantly move fore and aft on the dual cam and they will wear. We maintain this metal on metal friction to minimize sway. Yes the metal on metal contact will create noise when making turns and more noticeable when making turns at slow speeds. This is all part of how the system works with all the parts and pieces.
What a piece of engineering! I haven't towed with this yet but the design looks great. I've read other reviews about how long the installation takes, the directions seem simple so I don't anticipate any problems. My unloaded, as shipped TW is 600lbs, adding a battery and full propane tanks plus the hitch weight brings the TW up to 800lbs. I should have plenty of extra capacity with these.

I just pulled 500 miles with zero sway. When being overtaken by a semi, the whole rig wants to move instead of just the camper. I find this normal and acceptable.
OMG, the Reese straight-line weight distribution hitch is fantastic. No complaints whatsoever. Pull a 23 foot Rockwood trailer of 3,200 pounds with my 2016 Ram 1500. Pass the semi-trailers with confidence and absolutely no white knuckles. Great product.

Fantastic hitch!
Packedge arrived a day early which is good, heavy cardboard box, little damage from the long cross counry delivery, inside all o,k.
I installed the hitch as instructed without a problem, next week I hope to have a road test, it looks well built. Dodge Ram 2500 28' toy hauler.
Thanks guys.

Thanks for your letter.Your product is preforming very well. My trailer is very steady behind my track,
Exactly what I was looking for. Provides sway prevention rather than just control. Very noisy just like all sway control hitches. Definitely recommend.
Excellent product. It's an easy DYI installation. It only took about an hour to install to spec. Not much to say about the weight distro, other than it's nice to have my truck riding next to normal. I was most impressed with the built-in anti-sway in high winds while crossing a large body of water. Never once did I feel the vehicle was going to go off the bridge, or any whipping of the trailer. The two felt like one unit. Highly recommend this setup

I’m still pleased with the system. It was easy to install and configure
I have used the Reese weight distribution and sway control system twice now over the past year to tow a 6K pound, 30'Jayco travel trailer with my 2014 4x4 Tundra Platinum (which had, at the time of purchase, the largest tow capacity of any 1500 truck on the market). Before having the system installed, the trailer felt like a sail behind my truck and was pushing me around - felt like I was navigating an ocean liner. After the system was installed, I've taken the trailer over one of the most challenging (and beautiful) highways in the country - HWY 299 in Humboldt/Trinity County, California. This trek has steep grades, many poorly-banked hairpin turns, and gusty conditions, and I could barely tell I was towing anything. Huge difference in performance, and tremendous improvement in my peace of mind. Would highly recommend the system.
Note: I also have an aftermarket brake controller on the Tundra as the '14 model didn't come with an integrated controller. In TOW-HAUL mode, that truck has no problem in the muscle department towing that trailer, just needed the extra security/stabilization of the Reese system.
I purchased my hitch just before making a trip from the Seattle area to Yellowstone and Grand Teton National Parks (about 750 miles each way). I pull a Timber Ridge 250RDS travel trailer (31', 6200 lbs dry weight) with a RAM 2500, and could not be happier with this hitch. It is spendy, but you definitely get what you pay for. 1) It does an excellent job of preventing sway and provides a solid feel, making mefeel comfortable towing at speeds over 70 MPH. 2) I have noticed very little noise coming from the hitch compared to others that pop, creak, and groan. 3) It is very easy to hook up and disconnect, compared to others that involve kicking, prying and loud noises when installing or removing the WD bars.
I called etrailer and placed my order over the phone with Karen, and she made sure the order was shipped that day. Excellent service! The only disappointment was that the product had previously been opened, and some mounting hardware was missing. So, when I went to have it installed, the technician had to improvise. Not a big deal, but I wish that had been checked to make sure all of the pieces were there, since it had been previously opened.
I have had the use of this Item for about a year and i give 5 stars . I have pucharsed several item from this company it the past and as usual etrailer is spot on. Installed this hitch in no time. instructions are concise a clear and went on a test drive with truck and trailer. 65 MPH their is very little sway. Just a small amount when an 18 wheeler goes by but that is no problem. Buy it. You will sure like
This thing works well, as advertised. It did boost the rear end of the truck up immediately and seemed to have a positive affect on sway. I was able to back up with it as advertised.
The issue I had with it and what prevents me from scoring higher is despite the fact that I followed the instructions to the letter, the lower brackets are installed by drilling out holes and hammering in "blind" or knurled nuts. I was leery of their longevity and for good reason. After 1500 miles they wallowed out the holes and made one of the lower brackets loose.
My solution was simply to weld the lower brackets directly to the frame and its vastly superior to the install methods they advise and works great. However since not everyone is comfortable/set up to MIG welding these on and will rely on the foolish blind nuts I can only give it 3 stars.
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.
work great.It help with the big riggs not to pull are push when passing. I did not take bars off when turning are backing had no problem with bind are amount of area
to turn did not know it was back there when backing. Its not really hard to put together does take a little time to do it right by the instruction.
read all the way through Key points height of trailer hitch and what ball height your using. And last make sure you measure the front fender for the ride height.
I am really happy with it. We have a lot of down bust wind were we live and strait line distribution system w say bar works really good. our trailer
is 36 feet and 8 inch long from ball to bumper. 1000 lbs tung weight.
I had a reese hitch about 30 years ago, the hitch saved me from going into clear creek when my trailer was fishtailing it pulled it back straight behind my tow vehicle.
I went to a 5th wheel for several years then wanted to downsize to smaller trailer. Bought a pull behind and wanted a weight dist and sway control for it.
Bought the rp66084, you kept me informed about the shipping and when i would get it, came in by ups one box was crushed open but was no missing parts.
Have not had it on the road yet but sure everything will be ok.
I purchase a used trailer recently and have made several purchases from etrailer to include a Straight-Line Weight Distribution Hitch (RP 66084), 2 5/16 Ball (19286), RV Generator Plug (CAM 55333), Aqua Hose, sealing trim for roof and side seams etc...
All of the products have arrived on time and are of high quality. The trunnion bar holes on the RP 66084 were missed drilled so I called etrailer(Laser) and he shipped me out replacement bars which arrived sooner than expected along with a return label for the miss-drilled bars.
Products are quality, service is quality and inventory is exceptional.
It is a pleasure doing business with them.

I have now pulled my trailer over 8000 miles this year 22 ft rockwood about 5700lbs loaded with a jeep gladiator rubicon I never had any issues. I always hook up my sway control with no load much easier I followed the install video on e-trailer , very helpful not cheap but worth every dime to me
