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 Trunnion-Bar Weight Distribution

The easy-to-use, serrated washers on the Reese 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 this 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. 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 (sold separately).

Thoroughly torture tested between 7500 lb camper and 10500 lb trailerable a houseboat. Bought the anti-sway cams separately off [online] due to availability. Combined as a system, this stopped anti-sway and saved my butt during a hard downpour rain and side winds. The cams were the difference in pulling off to get to safety vs laying on the side of road upside down like some 18 wheeliers.

Yes, its expensive. No, you dont buy another one unless you sell it with the camper / trailer.



Ive used this on 10K houseboat trailers and 7.5K campers, this is the one you are looking for. The adjustable head makes all the different in adjusting weight between front and rear truck axles. It really does remove over understeer on the truck when set correctly. This was tested from 60 - 75 MPH, no death wobble. Purchase the anti-sway arms, after one good wind sheer, your nerves will thank you.


This was my first encounter with etrailer and I have to say it was hands down the best service I have ever received! Really.. And no I don't work for etrailer!!!!!! We use to live in a country where good service was just a way of life. Today, lets face it, service is terrible! But not etrailer.. I placed an order for this product online and selected the normal shipping method by ground. I immediately got the normal email "thank you for your order". But then I got another email from an actual person, George.. George let me know the product was in their distribution facility and will ship in 24-48 hours.. To my surprise, the order shipped the same day and I received another email from a Frank stating they took the liberty of upgrading my shipping to 3 to 5 days express shipping instead of the normal 5 to 7 days at no charge to me! So my response to this was "wow great service thank you!".. Again to my surprise I received an email from a Nikki who thanked me for my positive feedback. On a side note can you believe, they actually put their direct phone with extension along their email address on the bottom of their emails so you can actually get in touch with them? I didn't think this type of stellar service existed anymore.. Kudos to etrailer.. Ok, I think I almost forgot to write about the actual product.. The product was made very well, hooked up with no issues, and when I had questions on adjustments, you guessed it, i called and emailed folks at etrailer and they actually helped me!!!! They could have sent me a box of cracker jacks and I would have given then an excellent review! :) Keep up the great work etrailer... I won't shop anywhere else for my trailer needs..


Truck ended up in the shop. Blown engine. We cancelled the order for the time being. Sales rep was very helpful both in helping to order the hitch and canceling the order as a result of the engine problem.

I will seriously consider reordering a hitch from etrailer. The rep was very helpful on
helping us purchase the right hitch. It was delivered at the approximate time as promised. Unfornately we had to return it as the truck is in the garage.


Over satisfied with the Reese Straight Line hitch!! It does everything it says it will with no question!! I had a regular Reese equalizer and got a lot of sway with my 34 foot Springdale behind my 2016 Ram 1500 ecodiesel, and the Reese Straight Line eliminated ALL of it!! The installation process is a little tricky but with the instructions and the video etrailer has on YouTube, it worked out just great!! Completely satisfied with the help and knowledge from etrailer!!!!


I received box from UPS and look good. I checked up all parts and last year I bought new travel trailer They installed cheap EAZ elite and drive not safe sway. I decide to replace to new reese.Reason I would like put dual Cam High Performance in new Reese Rp66022 parts that I were ordered few parts in past and I read lot about your company that I like to read Tech experts Q & A. I felt to trust your company, lot feedback and show video and instructions.I knew your company make sure customer happy with it. I not put in hitch my truck for set up and drive yet . Here is snow and cold so I will install in soon.


Product arrived a day early. ETrailer has excellent shipping. I haven’t installed the hitch yet, however I opened the box right away. All of the parts were there and it was wrapped up very well. No scratches or chipped paint at all. Looks like a very good product. Can’t wait to use it. Thanks ETrailer.


This is my second weight distribution hitch, which was made by Reese and the first one was used from 1993 to 2017. Although I bought the trunnion bar hitch, as it was the same type as my first hitch, there are changes in the design of the hitch, which I believe will be improvements over the older design. I'm ready to get on the road with this Reese hitch pulling my travel trailer.


Updated my weight distribution hitch from 800lb to 1200lb. Vanessa helped me get what I needed. It was shipped and delivered quickly and at a fair price.


Lighting fast shipping!! Just received my hitch, and installed it last night. Straight forward instructions really took about an hour and a half by time I had it all adjusted and fit right. It seems to be well made and very heavy duty. I am super pleased with E-Trailer; their customer service is top notch (Andi Rocks!!).
I highly recommend E-Trailer for any hauling help..

The product was all it was advertised to be. Easy assembly very heavy duty. I have not towed my 33ft toy hauler camper yet but know it will be satisfactory. I would recommend this product.

Works as advertised. Wouldn't tow car trailer without one


The purchase experience with etrailer was great. The product arrived in good condition, and I appreciate the security considerations for on-line orders.


Converted from a Reese Round Bar 10000 to this Reese 12000 Trunnion Bar.

  • How to Determine the Towing Capacity of a 1997 Ford F-150
    From my research your 1997 Ford F-150 could have a maximum towing capacity up to 12,700 pounds if it's properly equipped. Exactly what your truck can pull depends on a number of factors like the engine size, transmission, and cab style. You should be able to look in your owner's manual and match up your truck's specs to see where your max is. If for some reason you aren't sure about the specs of your truck another way to find its towing capacity is to find the gross combined weight rating...

  • How to Determine Correct Weight Distribution System Spring Bars Are Needed
    Weight distribution hitches are classified by the range of trailer tongue weights their spring bars are rated for. If your current weight distribution hitch like the # RP66022 you'd looked at is rated for up to 12000 lbs, then the bars would be rated at 10% of that, which would be 1200 lbs. If the 6000 lb weight you mentioned represents the weight of the fully loaded trailer, then the tongue weight of the trailer should be somewhere in the 600-900 lbs range. To determine if the system...

And if it had the factory tow package and Class III, 2 inch trailer hitch the max would be 5,820 pounds. Consult your owners manual to confirm.

  • How to Convert a Round Bar Strait Line WD System to a Trunnion Bar
    The head and spring bars of your current system will need to be replaced. But the chain hangers and shank can be reused if you like. The shank is the portion of the system that slides into your hitch opening. Your best option would be the Trunnion Reese System part # RP66022 as this kit comes without a shank and does not have the dual cam system either but would be totally compatible with your dual cam setup since it has the trunnion bars with curved ends.

  • How to Release Tension on Weight Distribution Spring Bar So That Bar Can Be Removed
    If you are speaking of a weight distribution system that utilizes spring bars that are held in tension by chains hanging from the trailer frame, the easy way to take the tension out of the spring bar is to use the trailer jack to raise the trailer. Leave the trailer hitched to the vehicle, and use the jack to raise both the front of the trailer and the rear of the vehicle until the chain has enough slack in it for the chain hanger to be lowered. Make sure that the vehicle and trailer are...

  • How Much Does Weight of Towed Vehicle Affect Gas Mileage in Motorhome
    You ask an interesting question. I do not know of any formalized chart or table that can capture all of the variables in play in your flat towing comparison. Apart from the vehicles' weight difference there are many other factors in play, such as wind resistance due to differing profiles (although they are pretty close to one another in this respect) and tire tread pattern, tread wear and inflation level. In the simplest terms, if you ignore all of the other factors that could make a...

  • When Flat Towing a Vehicle How Much Tongue Weight is on the Trailer Hitch
    There are 2 different capacities independent of each other though related. Tongue weight is the downward force or weight on the trailer hitch. So it is pushing down at the back of the vehicle. The gross trailer weight is the weight of whatever it is you are towing. So for your motor home, at most you can tow 4,500 pounds gross trailer weight. Tongue weight is typically 10 to 15 percent of the gross trailer weight. However, when flat towing a car there is almost no tongue weight because...

    Well, I can't recommend measuring it weights since that is not how Fastway or Ford does it.

We have always sais that once your weight distribution system is set up and connected the wheel well height at the front and rear should be the same or within a fraction of an inch of the unloaded height.

When backing the trailer or turning very sharply the bar could come loose especially if the spring bars are not very tight.

So basically, the movement should be at the bars and not the brackets. I have included a link to the right to our informational article on weight distribution and sway control for you.

  • Will Using a Weight Distribution System Increase Towing Capacity of Vehicle
    An equalizing hitch or weight distribution can sometimes increase the capacity of the receiver hitch, but the vehicle manufacturers stated towing capacity or rating will always be the final determination of how much the vehicle can tow. Any towing system will only be as strong as its lowest rated component. I would urge you to abide by the stated towing capacity of your truck. Failure to do so can cause the hitch to fail or damage drive train components on the vehicle.

  • Is Weight Distribution Needed on 2008 Ford F250 Towing a 7500 lb Trailer?
    We recommend using a Weight Distribution System if your trailer weighs more than 50 percent of the tow vehicle weight. In addition to eliminating the squat experienced when the trailer is attached, a weight distribution system can lead to performance increases in steering, traction, and braking while also decreasing trailer sway. This is accomplished by the leverage provided by the spring bars which transfer a portion of the trailer tongue weight to the front axle of the tow vehicle. Weight...

Because a w/d system removes some of the tongue weight from the rear axle and transfers it to the front axle of the tow vehicle, using the system can increase performance in steering, traction, and stopping while also decreasing trailer sway.
