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.
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).

After a slight modification to my trailer (brackets fit a 2.5 inch frame; mine was 3 inches), this hitch fit perfectly and works great. Now I can tow a 3 ton tractor without worrying about putting too much strain on my rear axle.
Also impressed with etrailer.com's service - the hitch arrived much sooner than expected. Will definitely be doing business on this site again.
by: Kevin07/23/2022
Installed it today on my cargo trailer and 2022 Ford Explorer and took it for test drive to the local truck scale. Products and instructions were great. Pam was wonderful helping me pick out exactly what I needed (and not try to sell me things I didn’t need).
by: Bill S03/26/2015
Reese equipment quality is top notch. The adjustment mechanism at the head is what convinced me to pick Reese over other manufacturers. Customer service from etrailer is exceptional and will keep me coming back in the future.

I use this 1500 lbs WDH with my 14,000 lb equipment trailer and 10,000 lb dump trailer. Previously, I used a 1200 lb WDH.
I just hauled a load of pavers (a gross combined weight of just over 20,000 lbs) with 11,600 lbs on the trailer axles. I had 1400 lbs of tongue weight (used a scale to measure). The one-way trip was traveled on a two-lane highway crossing over five 5,000 ft mountain passes. Excellent hitch performance uphill and downhill through lots of tight curves.
The tension bars are easy to install / remove and they have great ground clearance. If it is necessary to adjust the hitch angle, the fine graduations for different hitch angles make it easy to get the exact angle needed.
Great product!

Had these installed by a dealer and drove a few hours to a campsite this spring. Only the second time driving a camper and first time on a major highway. White knuckle ride for the first half hour then realized the camper wasn't swaying or rocking and started to relax. Coming home two days later I started out relaxed and enjoyed the drive....even passed a truck!
by: John02/23/2022
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.

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..
by: Bernard M06/24/2016
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.
by: Arizona Slim09/25/2018
I really like the Reese Trunnion style weight distribution. It gives more clearance to the road than round-bar kits.
I appreciate the fact that the bars are available in different spring rates for different tongue loads. I dial my front axle load restoration (FALR) exactly to 100% and having a variety of spring rates makes this possible.
by: Ron11/10/2018
Not a whole lot to say about this product. It's works very well for us without any issue. Only complaint I have is not really product-related: The pipe used for lifting the bars into position is a tad longer than I wish it was. Reason being is that occasionally I need to have that bar completely vertical to get the chain on the trailer prior to lifting. The entire unit sits so low sometimes I have to cheat the system by choosing a link with less lifting power... then do the other side... then come back and to it all over again. Just a hassle and yes, i know I can just cut the bar with a cutoff wheel, but I just have not got to it yet.

Items arrived very quickly. Setup instructions were very clear. Would highly recommend Reese WD Hitch for all your heavy towing needs.
by: Mitch F.07/07/2016
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!!!!
by: H. S.10/16/2018
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.

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.

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.
by: Dan M.02/24/2014
Excellent web sight, I am a purchasing manager for a manufacturing firm and this sight is one of the best, very easy,
Product was delivered in good condition, one day late due to weather, but I was notified of the delivery change in advance!
Thanks, will be ordering more.

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.

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.
by: Ray Z.07/13/2012
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..

See what our Experts say about this Reese Weight Distribution Hitch
- Cargo Trailer Pulls Up On Ball and Makes a Lot of Noise Over Bumps at highway SpeedIt does sound like the tongue weight was not high enough. If a trailer is empty, you can experience some of these symptoms. The tongue weight of a trailer should be between 10 and 15 percent of the gross trailer weight. For example if your trailer was fully loaded and weight 7,000 pounds, the tongue weight should be between 700 and 1,050 pounds. Proper loading of the trailer will also help. Heavier items should be centered at the bottom and you would not want one side carrying more weight...
view full answer... - Adjusting Weight Distribution System to Eliminate Vehicle SagAssuming that the weight of your camper does not exceed the capacity of the spring bars, a combination of tilting the weight distribution head rearward and tightening the chain hangers by one chain link at a time should distribute more tongue weight toward the front axle of the vehicle, thus lessening the sag at the rear bumper. If there are less than 5 links between the snap up bracket and u-bolt connecting the chains to the spring bar, adjust ballmount angle rearward. I have linked...

A chain weight distribution hitch like the Reese Weight Distribution System # RP66021 will not have sway control built into the system. It would require you to add either Reese Dual Cam High-Performance Sway Control # RP26002 or a Reese Friction Sway Control Kit # 83660.

When calculating the necessary capacity of a weight distribution system, the weight of any cargo loaded in the tow vehicle behind the rear axle needs to be considered as well. The 5000 pound figure also includes an estimated 400 lbs of gear both in the trailer and in the rear of the tow vehicle. Given...

I would recommend you verify your tongue weight before you purchase a weight distribution system. If your loaded tongue weight is 700 lbs like you...

- High Performance Weight Distribution SystemThe part number you referred to is the Reese High Performance Trunnion System. The weight distribution system is designed for Tongue Weights between 400-800 pounds, and a total trailer weight of 10,000 pounds. These systems are not given a particular class like a trailer hitch is, although the weight distribution system does require at least Class III hitch for installation. The instruction sheet is available using the following link located below. For your convenience I have also attached...
view full answer... - Replacement Weight Distribution System for Reese System with Older Style HeadWe don't have that older style head anymore as it was discontinued. Honestly your best option will be to get a WD system that doesn't have a shank like the part # RP66021. This will allow you to at least reuse your shank but comes with new bars, chains, and hangers. This system has a tongue weight range of 400-800 lbs which is similar to the system you referenced.

Either way, you do not want to tow your trailer with a naked bar until the problem is fixed. If it came from the spring bar and it is the end that goes into the weight distribution head, it is probably the trunnion, like # 58098. This is the part that holds the spring...
