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).

Reese Weight Distribution w/out Shank - Trunnion Bar - 15,000 lbs GTW, 1,500 lbs TW - RP66131

Average Customer Rating:  4.9 out of 5 stars   (59 Customer Reviews)

High-performance system is designed to offer the best in weight distribution with an easy-to-adjust, forged head; a raised ball platform; and flexible, powder coated steel, trunnion spring bars. Adjustable shank and hitch ball sold separately.

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!



by:

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.

Wonderful. Make sure to keep your trunnions greased.



by:

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.

We are about to make our second long haul pulling our 8000lb travel trailer. Our Reese hitch makes all the difference between nail bitting and a relaxed trip. Still 5 stars



by:

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.



by:

Works great. Using on a 14000 lb. tag along trailer behind a dually pickup. Takes up the slop in the hitch so the ride is better.



by:

It was just like it was described. Came in perfect condition, fast delivery, no problems. I'll order again from etrailer.com.... They have what you need and want, beats shopping around all over town and the internet...



by:

Customer service was outstanding during the ordering process, hitch arrived as website indicated. Best price anywhere I could find. Thanks etrailer!

Huge difference over the old undersized hitch

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.



by:

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:

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:

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:

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.

  • Can Pro Series Weight Distribution System PS49903 be Upgraded to 1,200 lb Tongue Weight Setup
    Yes, you can upgrade your Pro Series # PS49903 to a 1,200 lb tongue weight setup with the spring bars # 58338 and you'd be set.

  • Weight Distribution Solution for Trailer with Propane Tanks Above Trailer Frame
    Since you have propane tanks above your RV frame in the location that the spring bar hangers would need to install you'd want to use a system that instead uses chains like the part # RP66131 for how the bars attach to the frame hangers and then instead use bolt on brackets like the # RP58305 which attaches to the side of the frame and does not require clearance above the truck frame.

  • Should Towing Setup with Weight Distribution go to Weigh Station to Verify Setup
    If the system is properly rated for the trailer and properly setup using the height differences of the fenders of the vehicle then I wouldn't put too much "weight" (pun intended) into what the scales show. We've asked our weight distribution manufacturers before how much weight should be offset using their systems and they say they can't really answer that as there's just too many variables. Do you know which system you have specifically and what your loaded tongue weight is? Keep in...

    For a 15K shank that is compatible with the Reese Weight Distribution # RP66131 you can use part # RP54970 which gives you a 2" drop/6-1/2" rise. Don't forget to grab a hitch ball like the 2-5/16" Curt # C40030 to complete your setup!

The Firestone Ride-Rite Air Helper Springs # F2250 will provide an excellent solution to those issues when pulling your travel trailer. Because the air springs install between your vehicle's frame and its rear suspension, they are designed to absorb road shock and soften any contact between your axle and frame, preventing your truck from bottoming out and resulting...

  • Weight Distribution System Recommendation for Trailer with 1,400 lb Tongue Weight and I-Beam Frame
    To install a weight distribution system on an I-beam trailer requires you to take the trailer to a welder to have them box the I-beam frame where you'll need to install the weight distribution brackets. This gives the brackets something they can attach to. For brackets then we have the part # RP58305. Then for a weight distribution rated for a trailer with 1,400 lbs of tongue weight we have the Reese system part # RP66131. For a hitch ball then you'd want the # 19286 and for a shank part...

  • Is Weight Distribution Needed for a 2016 Ford F-250 and Rpod 178 Travel Trailer
    Weight distribution is recommended if the gross trailer weight is at least 50 percent of the gross truck weight or if the rear end of the vehicle sags or you experience steering, visibility, or braking issues when towing. If none of that applies to your rig then you certainly don't have to use the spring bars in the set up. having them though does increase stability and will help to reduce sway beyond what the sway control unit alone can do.

  • Weight Distribution-Sway Control Recommendation for Towing a Crossroads Sunset Trailer with 2010 Ram
    The best way to select a weight distribution system for towing your Crossroads travel trailer with your 2010 Dodge Ram 1500 truck is to weigh the trailer when it is fully loaded and ready to tow. When weighing the trailer you will need to determine the gross trailer weight and the gross tongue weight, and add the weight of anything you may need to load behind the rear axle in the bed of your Ram to the tongue weight. Any time the gross trailer weight is heavier than 50 percent of the trucks...

  • Best Weight Distribution for 2012 Chevy Silverado 2500HD and 11,000 Pound Trailer
    To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle. Tongue weight typically is 10 to 15 percent of the gross trailer weight. For an 11,000 pound trailer that would make the tongue weight 1,100 to 1,650 pounds.

    It sounds like you are needing everything else but the dual-cam set up, is that correct? If that is the case, I recommend the Reese Trunnion Weight Distribution System, part # RP66131. This system is designed for trailers with tongue weights ranging from 800-1500 lbs.

Basically you would be at the edges of this systems range that is 800 to 1,500 lbs. For a shank you would then want the part # RP54970.

    If your motorhome does indeed have a hitch with a 10000 lb capacity, it means that the hitch is capable of towing a trailer weighing up to 10000 lbs. To confirm this, the hitch should have a sticker or plate on it listing the capacities. The tongue weight capacity should also be listed.

  • Why Not Directly Weld On Weight Distribution Brackets to Trailer Frame
    The reason to install steel plate to enclose an I-beam trailer frame to allow use of a weight distribution hitch's lift brackets is that this method makes for easier replacement of a bracket should one fail. If you directly weld the modified lift bracket to the I-beam then you will have a tougher time of removing it should it ever fail. Using the steel plate means you can bolt/clamp one on and more easily remove it if the need arises.
