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.


Block-Style Washer

Unique Features of Reese Strait-Line Weight Distribution

The easy-to-use, block-style washer on the Reese system makes adjusting the tilt of the weight-distribution head a snap. This uniquely shaped washer can be rotated and positioned between blocks on the weight-distribution head for simple, secure positioning. And the numbered sides provide reference points should you need to adjust your system between different tow vehicles. 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 to obtain the desired tilt.



The round spring bars of this system slide up into the weight-distribution head and secure with pins 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. In addition, 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.

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.


Comments
The noise you describe is a function of the metal on metal contact that provides the anti-sway component of the system. Because lubricating the contact points would defeat the sway control function, the noise is for the most point unavoidable.

Good quality product. It does take some effort to set up correctly. I had a pretty dramatic imbalance and it improved that, though not fully. You have to be realistic I guess. Overall I'm happy with it.




by:

This system is great, I have a 2009 ford F-150 crew cab and pulling a Coachman freedom express 20 foot trailer. Went through kanas City and the wind and tractor trailers were no match for this system. Never swayed once. I was going for the 260.00 system, but Im glad Judy explain to me and went with 600.00 system, Thank you.

There's always a good bit of wind in Wyoming -- the jet stream is about ten feet off the ground there. This product kept our RV trailer steady in all conditions. It's worth the cost.

Great pricing, quick delivery, easy install, tows very well.

Review from a similar Strait-Line in Weight Distribution Hitch


This is simply a very good hitch. Installation instructions produced a completely flat tow when the trailer settles on the truck. My rig is sway free there's no extra up and down movement. The hitch is quiet going forward and backwards. Just really pleased.


Comments
Very well. An excellent hitch.

Review from a similar Strait-Line in Weight Distribution Hitch


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.


Comments
No problems, hitch still performs as I described in my write up a year ago.

Review from a similar Strait-Line in Weight Distribution Hitch


It really does the trick in terms of keeping down the camper sway. I can now drive on the interstate with no problems. Before I got this hitch, I just simply couldn't take the constant fighting as the camper swayed from left to right. The noise is not near as much as was advertised. It pops occasionally when making a tight turn but otherwise we just don't notice it much. The installation is worth mentioning. First, I am not fond of installing items like this. However, my wife and I took our time and installed in in a few hours. The instructions were excellent and (of course!) I still found a way to deviate from them which extended the installation time. However, in the end, it was not a terribly difficult job. This is not our first weight distribution hitch, but it will likely be our last.

Review from a similar Strait-Line in Weight Distribution Hitch


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.


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

Review from a similar Strait-Line in Weight Distribution Hitch


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.


Comments
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

Review from a similar Strait-Line in Weight Distribution Hitch


I don't really have anything to compare this weight-ditrubuting hitch to because it is my first one. I had it installed on a 2021 Forest River Puma 37' foot travel trailer. I pull it with my 11 F350. Before the hitch, I hated pulling the trailer in crosswinds but after the hitch install the winds, dont seem to bother me at all. The hitch allows for tight turns and does not limit any movement. The trailer is much easier to pull and at times, I forget it is back there.

I did not install myself even though I typically would but did not want to mess up. I paid a local RV mechanic $100 to install the hitch. They completed the task in about 2 hours.

Review from a similar Strait-Line in Weight Distribution Hitch


Was not what I hoped, did not take the sway out of my 2021 Grand Design travel trailer. The hitch is now for sale online at half the price I paid for it. I built and installed gooseneck on my trailer... It now pulls great! Too bad you can not order the trailer built that way!


Comments
It is important to make sure the loaded tongue weight of the 2021 Grand Design Travel Trailer does not exceed the weight rating of the bars for this system which are rated for between 600 lbs to 1,200 lbs. Ideally you want the loaded tongue weight of the trailer to fall in the middle of that range to combat sway. I know that you ended up converting to a gooseneck but that is something to keep in mind for the future.

I won’t know much about the product until it is installed and we have taken a trip with it pulling our trailer. Check back in late fall


Comments
This has turned out to be one of the best purchases we have made for our trailer. The ride is much more solid now, I almost don’t know I am pulling a trailer. Plus, we used to have a separate anti-sway bar, one of those friction ones, but now we only have to attach these weight distribution bars and all is good. We are about to leave on a 3 month trip with the confidence that at least this part of our outfit is 100 ready for the challenge.

Review from a similar Strait-Line in Weight Distribution Hitch


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.

Review from a similar Strait-Line in Weight Distribution Hitch


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 .

Review from a similar Strait-Line in Weight Distribution Hitch


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

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.

This is a quality product from Etrailer.com.
It
does everything they claim it is supposed to do. I have used it three times now since having it professionally installed by my local RV Dealer. It has eliminated the sway problems that I had been having at different times on different trips with my 31 foot Rockwood Ultralight 2701SS.
Very happy with this product and even more satisfied with the quick and outstanding service from etrailer.com. You wont go wrong with this combination.

Review from a similar Strait-Line in Weight Distribution Hitch


Reese RP 66073, install on a 2017 GMC Sierra 1500. Used a drop shank because my truck (stock) hitch sits at 19”. Bought this product for a 7’X18’ V-nose trailer, system has a “standard” neck and this system is essentially perfect, had concerns at first. System is understandably overkill at first thought. I plan on pulling in the neighborhood of 9000lb from the coast of GA to Colorado Springs. I did not want to revisit this later on or part way through my trip! So getting this system should prevent any of the sway and weight sag during my haul. First day of install, system seems to work very well! Had concerns about the trunnions staying on at full turn but a full day of in town driving with and without load and zero issues. My setup is not a “forget it’s back there” configuration but a noticeable difference in pulling quality and stability overall! Finding something in the realm of 450’ pounds to torque the hitch ball is hard to do unless your in a specialty field. An install video online claims the rivet helicoils are 9/16, the system I received calls for an 11/16 hole for the helicoils. Local hardware stores skip right over 11/16 so if your at a lowes or the like, you will have to go with a unibit if this is the route you choose to take be very careful because going to the 11/16 setting will make for a loose fit for the rivets!! If you have the option I would suggest a 5/8” bit and file to get that snug fit that is required to ensure engagement on closed frame trailers! Other than that install was relatively painless. Lots of pulling and tightening if your having to install this manually!!

Review from a similar Strait-Line in Weight Distribution Hitch


I have been using this hitch for about 2 years now on my 20' flatbed trailer. It has been done everything I expected and excels at what it is designed to do. I have had my trailer loaded up to it's max weight (12k) on more than one occasion and this hitch keeps everything nice and level. I have never experienced any sway, but I am careful to load the weight on my trailer correctly. I had to use a drop shank #RP3344 since I have a 6" lift and 35" tires. My trailer sits perfectly level. etrailer is awesome - fast shipping and top notch customer service!!

It does the job very well. It provides perfect amount of weight distribution with great amount of adjustability according to your liking. There is no sway at all; even in very windy conditions. It is noisy - it pups and creeks when making turns when parking. Although it has great amount of freedom to adjust, it will make you work for it - it take lots of time to get it perfect; but if you take the time- you will get it perfect. You have to be mechanically savvy.

  • Using Weight Distribution Hitch on 2014 Honda Pilot 4WD Touring to Pull Coleman Trailer
    Generally a weight distribution hitch is called for when the trailer weighs half or more of the tow vehicle's weight. This condition applies in your case. However, as you noted, the (online) edition of the owner's manual for the 2014 Honda Pilot indicates on page 336 that weight distribution systems are not recommended and that improperly adjusted ones 'may reduce handling, stability and braking performance'. Unfortunately the manual does not offer any comment about a properly adjusted...

  • Measuring the Trailer Hitch and Coupler for the Correct Ball Mount on a 2003 Chevy Silverado
    When you measure the hitch height, the trailer should not be connected to the hitch. There will be a little sag when the trailer is connected. If you are experience too much sag, you might need to add a weight distribution system. With minimal sag you could use a different ball mount, or try moving more of the weight on the trailer back a little. For weight distribution, I recommend a system with built in sway control. Depending on the weight of your trailer, we have many systems available....

  • How to Change Weight Capacity of Weight Distribution System to Match Trailer Tongue Weight
    It sounds like perhaps your weight distribution system is not rated for your actual trailer tongue weight (TW). Keep in mind that in addition to the trailer's actual measured TW you need to account for the weight of any cargo in the truck that sits behind the rear axle, such as a tool box, loaded cooler or generator. This behind-the-axle cargo weight will act just like trailer TW and so it needs to be factored in to your TW measurement. That total TW needs to match your system's capacity....

  • What Would Cause A Bouncy Ride Quality with Trailer Weight Distribution System Installed
    Typically when a weight distribution system is causing the ride quality of the trailer to be rough or bouncy the issue is that the weight distribution system is rated too high for the tongue weight of the trailer. The spring bars need to flex a bit when in use and if they are rated too high they won't flex and this translates into a rougher ride quality. I am not sure exactly what system you have now, and I believe you may have accidentally typoed the tongue weight you have since it seems...

Based off those specs I recommend using the Strait-Line Weight Distribution System w Sway Control - Round Bar - 10,000 lbs GTW, 600 lbs TW # RP66086, which will give you really great sway control while towing with your 2021 Kia Telluride. This system uses double cam shocks to prevent...

  • Compatibility of Hayes Sway Master with NuCamp 3,500 lb Trailer
    The Hayes Sway Master Electronic Sway Control System # HA81775 will help with sway by activating your trailer brakes side to side as needed. That will work just fine on your 3,500 lb trailer. Your air suspension should help with the load leveling of your truck cargo, so you should be good to go. If you experience rear sag on your truck when towing, then you would want to consider weight distribution and a more mechanical sway control. I would have recommended using the Strait-Line Weight...

  • Weight Distribution and Sway Control Recommendations for 2012 R-Pod and 2007 Nissan Titan
    For your 2007 Nissan Titan and 2012 R-Pod, I have a couple recommendations for weight distribution systems with sway control. To address your issue with your LP tank mounts potentially blocking your chain holder, I recommend the Reese Chain Hangers # RP58305. They are an alternative for traditional lift brackets that will not interfere with your trailer frame-mounted items. You will have to drill to install, but once that is taken care of, they are easily bolted on. I have provided the...

  • Recommended Weight distribution and Sway Control for a 2017 Toyota Sienna
    The Reese Strait-Line # RP66086 would typically be an option I suggest, but since you are towing with a 2017 Toyota Sienna, you do have more limited ground clearance than an SUV or Truck. That being said, we do have a straight bar version of this weight distribution hitch that I do suggest. That being the Reese Strait-Line # RP66082. This will have the same weight ratings of 200 pounds to 600 pounds on the tongue and a max capacity of 10.000 pounds towing. With the estimated tongue weight...

  • Brake Controller Recommendation and Installation Instructions for a 2010 Jeep Grand Cherokee
    For your 2010 Jeep Grand Cherokee, I recommend the Tekonsha P2, # 90885. This is one of our highest rated and most popular brake controllers. I have included installation details for the brake controller below. To install a brake controller, you will need to do a little hard wiring. I spoke with my contact at Tekonsha and he stated that the only wire Jeep provides is the electric brake output wire that goes back to the 7-Way trailer connector. This wire is probably a light green wire that...

  • Using a Weight Distribution System to Level a 2006 Toyota Tacoma and Cargo Trailer
    The best way to reduce sag at the rear of a vehicle when towing a trailer is to use weight distribution. I recommend a system that has built-in dual cam sway control to prevent trailer sway before it starts. For the right sized system, you will need to know the tongue weight and gross trailer weight of the trailer when it is fully loaded and ready to tow. For example, if the tongue weight of the trailer is 400 pounds, you would need a system with a 200 to 600 pound tongue weight capacity....
