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.

Video Transcript for Reese Weight Distribution - WD With Sway Control - RP66083 Review

Today well be removing part number RP66083. This is the Reese Straight Line Weight Distribution System with Sway Control. It is going to be a Trunnion Bar Design and its going to include the shank as well as all necessary hardware including your 5/8th inch pin that comes with a clip. Now this system is going to evenly distribute the weight over the axles of the towed vehicle and trailer for stability and control and thats just going to help create a more level ride for both the towed vehicle and the trailer. Its going to feature the automatically self-adjusting, self-centering sway control thats going to work in a variety of situations. The sway control system is basically this system right here. Youre going to have one on each side of the system so youre going to have one on each side of your trailer frame.

Now in straight line movement, the cams are going to lock in position to hold the trailer steady despite crosswinds. When you go around corners, the cams automatically unlock and slide to allow full radius turns and then when you have those situations when you cant help but have to swerve, the cams are going to seek a straight line angle to help stabilize your trailer. Now the sway control is going to bolt onto the A-frame trailer tongue and attach the lift brackets using the chains. When you get the sway control system, you can see that the Trunnion Bar sits over the portion down there. It just lays on top of there. Then you have this bracket that attaches and then with a little U bolt, its going to hold the chain on there and its going to attach to the lift bracket and the lift bracket also attaches to your trailer frame. The good thing about this system is you dont have any large U bolts or platforms to interfere with frame-mounted items such as gas tanks, tool boxes or generators.

The Trunnion Bars are hot rolled and tapered for superior strength and flexibility, so the bars will flex appropriately over uneven terrain for a nice controlled even ride and then the sway control cams are going to provide attachment points for the spring bars. Again, theyre going to attach using those chains. The head assembly and the adjustable shank are included. The head assembly is going to feature a forged raised ball platform so thats going to eliminate the need for a raised hitch ball. Then here on the shank, its going to feature a nice solid steel shank powder coated finish so this is going to stand up really well against rust and corrosion. The spring bar tension is adjustable.

All you have to do is switch the links and the chains where it connects to the lift brackets. Thats going to allow you to fine tune your system. Another great feature is that you can easily get the tilt that you desire with the serrated washer design which you have one on each side. The serrated washers have little teeth in them that dig into the teeth or the grooves on the head assembly. Thats going to allow the head to get the tilt that you need for your particular application. Its also going to eliminate the need to have to pile on washer after washer to get the desired tilt that you need again for your towing application. The system is going to include the sway control cams, the head assembly, the adjustable shank, the lift brackets, the spring bars.

Youre going to get the lift chains. Youre going to get the pin and clip and youre going to get all necessary hardware. Now theres a few things in here that you dont necessarily see in our description that youre going to get. Youre going to get a snap up handle. This is basically to be used as a leverage device. Once you get the chains on the lift brackets, sometimes its really hard because of the tension to get the lift bracket back up into position, so the snap up handle allows you to gain some leverage, put it over that portion there and then youre going to be able to push it up into position. Once you have it up into position, you can easily attach and secure using the included pins. Its going to be same for each lift bracket. Its also going to come in handy to bring the bar of the bracket back down. That way you can remove the chains or you can adjust the links in the chains to fine tune your system. The hitch ball is also going to be sold separately. Now this one does require a threaded shank with an inch and a quarter diameter. It is going to come with a reducer sleeve. That way you can use a threaded shank with an inch diameter so that reduces it from inch and a quarter down to an inch. Thats optional to use, but keep in mind that if you do get a hitch ball with an inch shank diameter that that will only work with a reducer sleeve in the appropriate slot. Youre also going to get the shim. This is provided. Its designed to take out any gap or slack that you may have between the shank of this portion right here and the bracket of the weight distribution head. It would slide in there again to take out any slack. Its got the two holes in it. That way you can run the larger bolts through there and get it nice and secured. Its going to offer a tongue weight of 400 to 800 pounds with a gross towing weight of 10,000 pounds. The shank is designed to fit a 2 inch x 2 inch trailer hitch receiver that is rated for use with weight distribution systems. Now the lift brackets, they simply just go over the trailer frame, this portion here, and its got the set bolt on the back. You just tighten that up. Its going to apply pressure to the inside portion of your frame of the trailer and its going to hold the bracket in place. This is going to approximately take up about 5-1/2 inches of space along your trailer frame and it will not fit trailer frames wider than 2-1/2 inches. Youre going to position the lift brackets about 30 inches back from the hitch ball so youll do that measurement on each side to make sure that you an accurate installation of the life brackets. Now the shank length, were going to take a closer look at that real quick. You can see there that it has two different pinholes. It has one thats set a little bit further back, thats where I have the included the 5/8th inch pin installed. Then it has one thats set a little bit more forward. If we take a measurement from the center of the hitch ball back to that closest pinhole location, thats going to give us a measurement of about 14 inches and then to the further back pinhole location, its going to measure about 15 inches. The total height adjustment that youre going to have along the shank is going to measure 5-1/4 inches. The maximum rise that youre going to be able to get out of this system is going to be 6-1/2 inches and the maximum drop is going to be inch and a quarter. Thats measuring from the top of the hitch receiver opening to the ball platform. Everything is a steel construction. It has a really nice black powder coat finish on it so its going to stand up really well against rusting and corrosion and its going to provide a really long life for everyday use. Its a great system to have. Again, its all about safety and creating a more level ride for both the tow vehicle and the trailer. Thats going to do it for our review of part number RP60083. This is the Straight Line Weight Distribution System from Reese. .

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. 216549

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. 281068

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. 608555


Comments

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.

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... 476947

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 . 287015

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. 174821

Review from a similar Reese Strait-Line in Weight Distribution


I've had this product installed for about a year. I race motorcycles and installed this on a 35' toy hauler that use at least once a month. Hooking it up to the truck is simple with the sway bars, and it helped to greatly reduce the sway travelling down the road. Toying something that large without a system like this is a safety issue, and I feel much better toying now with it on. 588723

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. 569248


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.

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.

Review from a similar Reese Strait-Line in Weight Distribution


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

Review from a similar Reese Strait-Line in Weight Distribution


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!! 567887

Review from a similar Reese Strait-Line in Weight Distribution


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

The weight distribution hitch and dual cam sway control were installed on a 2005 F250 pulling a 2003 Jayco "toy hauler". The instructions were very easy to read and understand making assembly and adjustments easy. The only complaint I have...A $500 hitch shouldn't have chips of paint missing and all "scuffed" up when it arrives! 400506

Review from a similar Reese Strait-Line in Weight Distribution


I have a 21 foot travel trailer that I pull with a Nissan X-Terra. Before getting the Strait-Line Weight Dist. System, the back of the X-Terra and the front of the trailer would be too low, creating a "V" at the hitch connection. In addition, out on the highway, the trailer would sway, particularly on the down hills, and at times would get so intense I was afraid the sideways energy created would force me into oncoming traffic or off the road to the right. After installing the Strait-Line system, the X-Terra and trailer are leveled out and the sway problem has been completely eliminated. I could not be happier with the results. I would recommend this product to anyone having these problems. Do your research to make sure you get the proper size for the unit you are pulling. 447176

A couple of months ago I purchased a 2017 Ford F150 with the built in sway control. The new truck pulls the trailer much more easily than my Nissan X-terra did. Although hooking up the trailer to just the ball hitch on the new truck is much easier than having to use the Strait-Line Weight Dist. System, I do find that the trucks built-in sway control, although adequate, does not work as well as the Strait-Line system does. The trucks built-in system can get overwhelmed by excessive sway and must rely on an automatic deceleration system to correct and control the sway, which can at times be a bit of a challenge until you get comfortable with it.

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

This is a comment on the excellent service from etrailer. I had to return the Reese Strait-Line WD with Sway Control hitch without attempting to install it. Etrailer made the return easy with no hesitation to accept the item back for full refund. It was a pleasure to deal with them. I would most certainly use their company again in the future. 160472

The entire package is awesome , did as promised and fixed sway of trailer. I am pulling a 33' Weekend Warrior Toy Hauler. The trailer is heavy 11.500 lbs. and has a heavy tongue weight as well. Air bags on a 3/4 ton Denali diesel and this trailer pulls straight and true. Should I purchase another tag along this will be the hitch I go with again. Researched Hensley and a few other anti-sway hitches in detail and this is what has worked. A lot to set up for every trip but does as promised and creates a level of safety comfort for me the driver. 328580

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

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. 231511

Review from a similar Reese Strait-Line in Weight Distribution


We recently purchased a larger travel trailer and decided to upgrade our weight distribution system. After reading Etrailer reviews and going with the suggested setup we bought the Reese Strait-Line system RP6613. Setup was time consuming and very finicky. Unfortunately getting the system setup so the cams ride in the bars properly was extremely difficult and frustrating. The weight distribution part worked great as advertised. The sway control on the other hand seems nonexistent. Equalizer WDS setup, adjustment and performance are far above the Reese systems. 151055

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... 59938

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. 208694

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.

Review from a similar Reese Strait-Line in Weight Distribution


Company Rep ( Tommy C) was amazingly helpful in doing rapid research with Reese company and determining that my existing system although still functional contained obsolete parts and should be replaced to accommodate second trailer needs. New pets order was immediate and I received all necessary parts on 3rd day from order. Exceptional! Now a design complaint regarding mounting the Reese Sway Control brackets to trailer frame tube (2"x6"-1/8" ) with press in "nut rivets". This frame is not adequately thick enough to accept this attachment procedure unless these items are welded in place to keep them from "stripping out". Holes in frame were correctly drilled per instruction. My machine shop, one of the most respected in Illinois, that this is a very common situation which can only be remedied by a skied welder. This is something that Reese and you should address. Hope this will assist others. Thanks for your excellent service. 196491

  • Is Factory Sway Control on a Ford Truck Good Enough for Towing a Trailer
  • The built-in sway control on your 2013 Ford truck works by apply the brake or more or less power to one side of the vehicle to correct a sway condition when detected. This is a passive system and will only engage when swaying already has started. If you used a Strait-Line system like # RP66083 the dual-cam sway control works as an active system. It will keep the truck and trailer in a straight line which stops sway before it starts. You could technically have the Ford system on with...

  • Is a Weight Distribution System Needed for a 2012 Nissan Pathfinder to Tow a 2014 Jayco x18d

Weight distribution is recommended if the trailer weighs more than 50 percent of the tow vehicles weight. Your 2012 Nissan Pathfinder probably weighs in the ball park of 5,000 to 5,500 lbs. Before choosing a weight distribution system, you will want to make sure your trailer hitch is rated for weight distribution. Your owners...

  • How to Choose a Trailer Sway Control Solution
  • The anti-sway solution you need will depend on the weight, length and trailer you're towing. If you're towing a smaller flatbed utility type trailer that gets a little unstable from time to time, and moving more tongue weight to the front of the trailer isn't improving the swaying condition, then an entry-level solution like the Pro Series Friction Sway Control, part # 83660 would be a good choice. For trailers longer than 25 feet, you can actually use two units, one on each side if necessary....

  • Why is it Important to Make Weight Distribution Head Angle Adjustment
  • Weight distribution heads are adjustable to get the spring bars level or just below level with the trailer frame. Depending on the trailer frame, the head may need to be set at 90 degrees, it also may need to be tilted down as far as possible to keep the trailer level. This will also depend on the weight of the trailer and strength of the suspension on the vehicle. Head angle affects bar tension. With too much spring bar tension the rear of the vehicle could lift.
