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).

Video Transcript for Reese Weight Distribution - WD Only - RP66020 Review

Today we're going to be taking a look at part number RP66020. This is the Reese Weight Distribution system. This unit is going to help evenly distribute the weight over your axles on both the tow vehicle and your trailer for stability and control. Ultimately, it's going to create a more level ride for both the tow vehicle and trailer. This particular unit's going to use the trunnion spring bars. These are going to be hot rolled and tapered for superior strength and flexibility. These bars will flex appropriately over uneven terrain for a nice controlled, even ride.

Here on the ends, they are going to be curved for use with the Dual Cam Sway Control system, sold separately at part number RP26002. Now the spring-bar tension can be adjusted simply by switching the links here at the lift brackets. It's going to allow you to fine tune the spring-bar tension. Here at the head assembly you can obviously see that we do not have a hitch ball included with the part number nor do we have the adjustable shank that slides into a two inch by two inch hitch that's rated for use with weight distribution systems. Those are going to be the only two components that are needed for the unit to be functional that are not included with the part number. If you are in need of those, you can find those on our website.

We offer a variety of options to choose from in those areas. This right here is going to feature that forged, raised ball platform. It's going to eliminate the need for a raised hitch ball. You can also achieve the necessary tilt that you need depending on your application because this unit doesn't use the old washer design where you have to stack on washers on washers on washers on a rivet. What this uses is a serrated-washer block design right here. That's going to allow the head to tile as needed to best fit your particular application.

That's a great benefit to have. You can also see everything else that it comes with here. You're going to have the serrated-washer design, lock washers, nuts, the two big bolts to hold the adjustable shank. Now sometimes we notice a little bit of play in there. They do provide this shim, that's going to be this piece right here, it's got the two holes for the bolts to run through. That will potentially take out that play that you may notice.

A lot of applications don't even notice that but in yours it may be different so you just never know so they provide that just in case. You're going to get your standard 5/8 inch hitch pin and clip, this is going to be to secure that adjustable shank inside your 2 inch by 2 inch hitch, and it's going come with the clip. Now the diameter of our hitch ball hole right here, this is going to give us a diameter of an inch and 1/4. If you want to use a hitch ball that has a shank diameter of an inch, you will have to use the reducer sleeve. It goes in there and it reduces it from an inch and 1/4 opening to an inch opening. Again, that ball is not included, it's sold separately. Then it's going to have the hole right here on the head assembly that is traditionally used with a friction sway control system. Excuse me. This right here is going to be our leverage bar. This is going to be used to go over this point right here. Sometimes when we have that spring-bar tension in place, this unit or this piece of the lift bracket can be hard to lower and raise. Sometimes it's not very safe to do that by hand so Reese is going to include this extension bar. It allows us to get the proper leverage that we need in order to get everything situation, whether it's in the up position or whether it's in the lowered position to disengage or to remove the chain from the lift bracket. Here on the back side, we're going to have the large screw. This is going to ensure that the lift bracket is tight up against the frame of the trailer. Now the lift brackets are going to require approximately 5 1/2 inches of space along the trailer frame and they will not fit trailer frames that are wider than 2 1/2 inches so keep that in mind as well. The system's going to include everything that you see here on the table, all the hardware and all the different things that I've gone over. When it comes to the tongue weight of this system, we're looking at 200 pounds to 600 pounds with a gross towing weight of 10,000 pounds. Again, it is designed for 2 inch by 2 inch trailer hitch receivers that are rated for use with a weight distribution system. Reese is going to put a limited lifetime warranty system but it's a great system and again ultimately this unit's going to help create a more level ride for both the tow vehicle and your trailer. That's going to do it for our review of part number RP66020. This is the Reese Weight Distribution System.

Install is easy but you will need a high torque drill. I took it to the shop and they had it on in 20 minutes. I am very pleased with the improvement in safety and stability and with the ease of use and removal. It is exactly what my Avalanche needed to haul heavy loads!

  • Weight Distribution System for a 3500 lb Trailer Towed By a 2008 Nissan Pathfinder
    The Reese Weight Distribution System, # RP66020, that you referenced has a tongue weight range of 200 lbs to 600 lbs. As long as the tongue weight of your towing setup falls within that range, this system will work well for you. The tongue weight of your towing setup will include the loaded and ready to tow tongue weight of your trailer plus the weight of any cargo in your 2008 Nissan Pathfinder loaded behind the rear axle. This system does not require any drilling to install and can...

  • Recommended Strait-Line Weight Distribution Hitch for 6600 lb 34 Foot Camper with TW of 700 lbs
    Due to the length of the trailer, I believe a Strait-Line Weight Distribution System that combines weight distribution with the Reese Dual Cam Sway Control would be your most effective option. When the trailer tongue weight is determined, make sure to include the weight of anything stored in the truck bed behind the rear axle. If the 700 lb figure represents the fully loaded and ready to tow tongue weight of the trailer, then there are two different Strait-Line systems that would work...

    On page 4-65 of the online owner's manual for the 2005 Chevrolet Avalanche 1500 4WD the towing capacities for the two axle ratios are listed. If you have the 3.42 axle then the maximum trailer weight is 7100-lbs. If you have the 4.10 axle then the maximum trailer weight is listed as 8000-lbs. I suggest you review your own printed owner's manual to confirm your truck's towing capacity. Clearly your trailer's maximum gross vehicle weight (GVWR) of 8810-lbs exceeds that of the Avalanche...

  • Weight Distribution/Sway Control System for 23-Foot Trailer Pulled by 2010 Chevrolet Silverado 1500
    Selection of a weight distribution/sway control system hinges primarily on the trailer's fully-loaded ready-to-tow tongue weight. Dry weight does not tell you what capacity system you'll need for proper weight distribution to your tow vehicle's front wheels. The system you referenced, Reese # RP66020, works with trailers whose fully-loaded tongue weight ranges from 200 - to 600-lbs and so this would likely be too light a system for your trailer's empty weight of 550-lbs.

    As you are currently set up, you should have no problem towing a trailer of that particular weight, but the trailer you mention is pretty long. I would consider going with a weight distribution system because of the improvements in ride, steering and braking that the system would give you.

  • Weight Distribution with Sway Control and Brake Controller for a 2007 Chevy Tahoe and Car Hauler
    Adding a weight distribution and sway control system to your 2007 Chevy Tahoe will help with the stability problems you are experiencing. The correct system depends on the tongue weight of the trailer when it is loaded. Your trailer tongue weight should be about in the middle of the tongue weight capacity of the system you choose. So if your trailers tongue weight is 1,200 pounds, you will want a system with a 700 to 1,400 pound range. An example of a system in this range is the Reese...

  • Availability of Weight Distribution for 1-1/4 Inch Receivers
    Weight distribution systems are only available for vehicles with a Class III or higher rated hitch with the 2 inch receiver, not the 1-1/4 inch receiver on a Class I or Class II hitch. Your best bet would be to replace your existing hitch with a Class III hitch. With a Class III hitch, for a trailer such as yours, I would recommend the High Performance Trunnion System, part # RP66020. This system is rated for trailers with tongue weights ranging from 200 to 600 lbs. Since a trailers...

There is not a Class IV hitch offered for the MDX.

  • Which Weight Distribution System for a 2008 Toyota Tacoma Towing a 2009 Forest River Trailer
    Typically, the tongue weight of a trailer (the downward force that the coupler would exert upon the hitch) is 10 to 15 percent of the trailer weight. Therefore, you would need a weight distribution set up that would handle at least 600 pounds. This Reese High Performance Trunnion system, part # RP66020, would be ideal for your application. It also has the capability to utilize the Dual Cam Sway Control system, part # RP26002. I have added links to these parts and their instructions below.

The Reese Weight Distribution, # 66557, is designed for light trailers with A-frame trailer frames that measure up to 6 inches tall.

  • Recommended Weight Distribution for Towing 2500 lb Trailer w/ 2011 Chrysler Town and Country
    Using a weight distribution system to level the van's ride height while towing is an excellent idea. The best system for you will depend on the type of trailer you have. If you have an enclosed or travel trailer, I recommend going with a w/d system with an integrated sway control component as these types of trailers are susceptible to trailer sway caused by crosswinds or turbulence caused from oncoming traffic. To choose a system with the proper capacity, you'll need to determine the...

  • Is Weight Distribution and Sway Control Necessary on 2011 Keystone Towed by 2011 Silverado 2500
    Any time the trailer weighs more than half the weight of the vehicle, we recommend weight distribution. The OEM sway control is similar to a traction control system. The vehicle can sense trailer sway by the movement of the rear of the vehicle. Power is then sent to one wheel or the other in order to combat trailer sway. I do not have any personal experience to be able to say how well it works, and the comments I have heard about it are not definitive one way or the other. My best...

    Reese weight distribution shank # RP54998 and the one that comes with Curt weight distribution system, # 17300, weigh about the same which is 20 pounds so you would not benefit from switching shanks. The various weight distribution heads also weigh about 20 pounds (not counting the ball) so really you are looking at a combined weight of around 40 pounds no matter which system you go with.

    Since you need a 5 inch drop to tow your trailer you would actually want the shank-less version of the RP66540 that you referenced which would be part # RP66020. This will allow you to then buy a shank that would allow you to do up to 5 inches of drop like the part # C17121. The system mentioned uses trunnion spring bars so it will give you the best possible ground clearance over the round bar setups. For a 2 inch ball you would want part # A-90 and for a 2-5/16 inch ball # 19286.
