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 trailer with 600 lbs – 1,200 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

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.

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. 447030

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. 475620

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. 50034

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.

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. 691354

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

It was OK. Put it on my trailer in place of a ProPride P3 so renters could use it. Drove less than 30 miles with the Reese, and the ProPride went back on. It's a much better hitch. Trailer can't sway with a ProPride. Got a very lightly used Reese available, by the way. 941591

Pulling a trailer from Oklahoma to Wyoming and the one thing you’re guaranteed; wind and fast moving semis. When you see enough trailers on the side of the road flipped, knowing you have the additional help off the bat to control your own is peace of mind worth the price. Pulling through 80mph crosswinds or a blizzard, having this piece of equipment is a lifesaver. My only gripe is the install can be challenging and ended up just watching online videos. You’ll end up buying additional trailer mounts for faster hook up if you have more than one trailer. 919506

etrailer did a fabulous job coordinating many products for my application. I am towing a sports car hauler/ camper combination trailer with a 2014 Jeep Grand Cherokee V8. It all works extremely well. Backing up goes very well too, even if I do have limited view, I can always see one side at a minimum. Thanks for the knowledgeable staff! I had a lot of questions and wasn't entirely sure which setup would suit my situation best, and they guided me to the setup best for me. 699266

- RP66084

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. 692526

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.

Product works great for my setup, before I had a standard weight distribution system and my 37’ camper was all over but with this trunnion setup greatly reduces my white knuckle driving I experienced before. It does take some work to install but got it done in about 3 hrs because I checked and rechecked before drilling the necessary holes in the tongue. 640026

Love this. Never feel sway and being able to back up without discontecting the bars really helps. Definitely would recommend 610908

If it isn't then you are not getting the full benefit of the system. The easiest way to measure that is to compare the ride height at the front and rear wheel wells with and...

  • What is the Best Type of Weight Distribution System with Sway Control
    The best weight distribution systems with sway control that we offer are the Reese Strait-Line systems, such as the # RP66084 that you referenced. The Strait-Line weight distribution systems use the dual cam type of sway control which is a proactive style of sway control that keeps the trailer inline with the tow vehicle at all times to prevent sway from starting in the first place, rather than trying to correct it once it starts. The other types of weight distributions such as the...

  • Replacement Lift Bracket for Reese Strait-Line Weight Distribution System
    The Replacement Lift Brackets with Handle for Reese Weight Distribution Systems # RP6637 is what you want for your Reese Strait-Line dual cam # RP66084. This is the proper replacement for the tongue weight you are referring to. If you just want the single replacement # RP21501 which is rated for 600 lbs is what comes with the unit, so the # 58392 is a stronger bracket rated for 800 lb tongue weight. The head, cam arms, and brackets share the weight, so rest assured these are the proper...

  • Weight Distribution Recommendation for 2018 Grand Design Imagine 2600RB
    If your loaded tongue weight (counting weight from cargo behind rear axle of tow vehicle) is 594 lbs then yes your 800 lb Pro Series WD system would be rated perfectly. If your tongue weight is going to be higher than that you'd want to go with a higher rated system like the Reese Strait Line part # RP66084 which has a tongue weight range of 600-1,200 lbs and features only sway control that works to prevent sway before it starts. For a 2 inch ball you would want part # A-90 and for...

  • Weight Distribution Hitch Recommendation for 7,000 lb Trailer
    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 tongue weight of your setup to fall right in the middle of the tongue weight range of the system you use. If your trailer will be around...

  • Will a Big Dip Damage a Weight Distribution System Since It Is Designed for Level Towing?
    The Reese Strait-Line weight distribution hitch # RP66084 is designed to keep your vehicle and trailer level, so a big dip could cause damage. I don't believe you will have any issues as long as the bars and hangers don't bottom out. The V shape you referenced does give me pause, so if you are concerned it is best to be cautious and connect the system after you leave the driveway.

  • Weight Distribution Recommendation for 6,000 lb Camper Trailer
    You'd be fine to have a weight distribution installed on your trailer as you travel on the hill you described. If anything it might help prevent the trailer from leaning excessively. For a 6,000 lb trailer you'd be looking at a tongue weight most likely of 600 to 900 lbs so the weight distribution with sway control that I would recommend is the Strait Line part # RP66084 which has a tongue weight range of 600-1,200 lbs and features only sway control designed to fight sway before it starts. For...

  • Weight Distribution System for a Trailer with 1,000 Pounds Tongue Weight
    If the tongue weight of the trailer is 1,000 pounds you need bars that exceed that weight. Both 500 and 1,000 pound bars would not be enough to be effective. The rating on a bar is for a set so if a bar says 500 pounds then the system, including both bars, is rated for 500 pounds. For 1,000 pounds tongue weight I recommend a system that is rated for 800 to 1500 pounds tongue weight like # RP66130. This system also includes dual-cam sway control. You will just need a properly sized ball...
