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.

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.

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 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. 403322

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.

I bought the Strait-Line Weight Distribution System w Sway Control - Trunnion Bar - 12,000 lbs GTW, 1,200 lbs TW for my 18 foot trailer used to haul just under 10,000lbs of Tractor and implements on winding Tennessee roads with my 2014 Double Cab 4.6 liter Full Bed Tundra. The product works great; I almost don't realize the trailer is there. Everything is level with no drop at the front and 1/2 to1 inch drop at the back depending on what's loaded. There is normally about a 3-4 inch drop in the back. Be aware that the box will be delivered at just over 90 pounds. The installation is not technically difficult, but you will need more tools than the instructions indicate to get everything together. The high torque bolts and as well as the 450 ft/lbs ball torque require some specific large wrenches and sockets. If you go through the instructions and pieces for the actual size of the bolts required, it will save you some running around to find tools. Invest in a step drill bit and it will save some hunting. With everything in place and ready to go, this was a solid 8 hour install with a lot of low to the ground squatting and bending which you will feel the next day. If I were older (46 now), I would have a professional install this. If you do, they will need a fully loaded trailer to finish which you will also need to finish the install. There is one piece in the instructions for installing the optional 1/2" x 1.00" SELF TAPPING SCREW into the snap up braket First, this is not really optional, but the instructions indicate to drill a 9/16" hole for this 1/2" screw which is incorrect and will cause you to not be able to tighten the screw down. The whole should be 1/2". Don't be tempted to put these in before the very last step after everything is hooked up or you will be very unhappy. The snapup brakets get moved around several times between the WD and Sway Control sections. The only negative (if it is negative) is that for my trailer height of 16", the trunnions are only 5 1/2" of the ground which can make speed bumps and the like an interesting experience as the do contact the road as the trailer wheels go over those bumps. If you are converting from a normal ball hitch off the back of the truck to this for the first time, your break away wire and safety chains will now be too short to connect to the truck (in all likely hood). You will likely need to either add to or replace those as well. All in all, the system works great, is technically easy to install with all the correct tools and sufficient time. 193724

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 199001

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

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

- RP66084

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

  • Recommended Weight Distribution System For Torklift SuperTruss Extension
    With a camper on your truck it is difficult to accurately measure your trailer total tongue weight because the cargo weight behind the rear axle is actually spread over the frame and not directly behind the rear axle.

    Your best option is going to be to install the bolt on brackets part # RP58305 that you mentioned as there isn't a shorter bar option available and since this bracket was basically designed for V-nose trailers like yours we know it would work well. I attached a picture that shows how the brackets would work in a similar situation.

  • Weight Distribution System Recommendation for a 2015 Chevy Silverado 1500
    For a trailer that weighs 8k I would recommend you use a WD system. Especially since your owners manual say anything over 7k requires one. 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...

  • Can Weight Distribution and Sway Control be Used on a Vehicle with Active Air Suspension
    The dual-cam sway control brackets on the Strait-line weight distribution system, # RP66084, do require drilling into the trailer frame but the spring bar brackets do not. They are held in place with set screws. If the active air suspension system can be easily deactivated, that would be ideal. If it cannot be easily turned off, you will first connect the trailer, then let the active air suspension system adjust. Then you will hook up the weight distribution spring bars. This may cause...

  • Recommended WD that has Sway Control, Allows Backing Up, Includes Shank, and Can be Used with Brakes
    I do have a recommendation for you to check out, plus I have attached a link to our selection of Weight Distribution (WD) systems that meet the criteria that you specified. As far as ground clearance goes it really just depends on your towing setup. All WD systems have some height adjustability so that the WD can be tailored to the weight and height of the towing setup. Since they do sit under the frame of your trailer your ground clearance will be reduced. My favorite WD system that...

  • Weight Distribution Recommendation for a Keystone Zeppelin EZ190
    For your application I recommend going with the Reese Strait-Line # RP66084 because it offers the best sway-control on the market and it has a great tongue weight range of 600 lbs - 1,200 lbs. Since weight distribution tongue weight takes into account the tongue weight of your trailer when it is fully loaded plus any weight that sits behind the rear axle of your 2013 GMC Yukon this system is actually the perfect strength for your setup. All you need to do is add a 2" # A-90 or 2-5/16" #...

  • Will Tongue Weight of XLR Boost Toy Hauler Go Up When Loading Side By Side
    Toy haulers actually carry their "toys" in the back of the trailer. I looked up your XLR Boost 27QB toy hauler and this is true for it as well. Because of this you wouldn't increase the tongue weight when loading the SXS. It's even possible the tongue weight might go down. A weight distribution system would still be recommended since you are close to the capacity either way. The best system will be the Strait-Line part # RP66084 which has a tongue weight range of 600-1,200 lbs and features...

  • 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...

  • Can Pro Series Bar-Style Friction Sway Control Be Used on a Valley Weight Distribution System
    Valley went out of business a couple of years ago. As long as the head that holds the ball on your Valley weight distribution system has a small hole off to the side on the top then you can use a friction sway control unit such as # RP66084. You mentioned that your Valley system is 70210 which is the round bar system and the head does have the hole for a friction bar-style sway control unit.

  • Determining Old Weight Distribution System Manufacturer and Replacement Part Options
    It does look like an old style Reese system. We have seen a few of these and they are similar to the newer version # RP66084. The part pictured has been replaced with the newer dual cam system yet they function in a very similar way. They no longer make that system, so I recommend upgrading to the newer system if you need replacement parts as those parts are no longer available. I've attached an article on weight distribution systems to further assist if you want information on...

  • 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...

  • 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...

  • Weight Distribution/Sway Control for Enclosed V-Nose Trailer with Limited Frame Access
    Thank you for the photo of your v-nose enclosed trailer for which you are looking for a weight distribution/sway control (WD/SC) system. Since you have limited access to the trailer frame, about 15-inches based on your photo, I suggest you check whether the diamond-plate nose blocks access to the side of the frame further back, say around 30-inches back from the hitch ball. This is hard to tell from the photo due to the camera angle. If the bottom of the diamond-plate does not extend...

  • Recommended Weight Distribution System for Coachmen Freedom Express Trailer with 900 lb Loaded TW
    For your Coachmen Freedom Express 248rbs travel trailer, I recommend the Strait-Line Weight Distribution System w Sway Control - Trunnion Bar - 12,000 lbs GTW, 1,200 lbs TW # RP66084. This system actively works to prevent trailer sway and keep your trailer in line with your towing vehicle. It is easily my favorite system based on the design features and function. The dual cams and the hot rolled spring bars create a very user friendly system with adjustability for driving preferences....

  • Recommended WD System for a Rockwood 2109S or a 2510S Travel Trailer
    My personal favorite Weight Distribution (WD) systems are the Reese Strait-Line because they are one of the few systems that actually fight sway before it starts instead of correcting it after it has initiated. You want to choose a WD system with a Tongue Weight (TW) range that the Total Tongue Weight (TTW) of your towing setup falls in the middle of. To find the TTW of your towing setup you will need to add the TW of your fully loaded and ready-to-go trailer along with the weight of...

  • Comparing Reese Strait Line vs Steady Flex Hitch for Ease of Removal for Storage
    The Reese Steady Flex # RP66560 will be 75 lbs total and the Strait-Line Weight Distribution System w Sway Control # RP66084 will be 113 lbs. The complexity of the systems to disconnect for storage will be similar, so I would just mark the trailer for easy reinstallation. The Strait-Line is a better system for sway control, so that is my recommendation for you. It appears more complex with the cams, but to remove it is really the same number of bolts. You will want to make sure...
