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.

Video Transcript for Pro Series Weight Distribution PS49581 Review

Today we're going to be taking a look at part number PS49581. This is the Pro Series RB3 Weight Distribution System. The unit's going to help evenly distribute weight over the axles of your tow vehicle and trailer, offering stability and control. Ultimately, it's going to create a more level ride for both the tow vehicle and the trailer. This unit's going to feature your round, tapered spring bars, these are going to flex appropriately over uneven terrain for a nice, controlled, even ride. You can see right here how they slide into the head assembly, and then they're going to have these locking tabs to help hold them in place. Located on each end of the head assembly, right where those spring bars go in, we're going to have the Zerk fitting, that's going to allow for easy maintenance.

You can simply attach a grease gun to that an pump in the grease, that way you can lubricate that area. When it comes to the head assembly, you can easily tilt the head so you can get the desired angle that you need. It's going to use the traditional spacer rivet and washer design right here. It's going to come with all the washers you need, and a spacer rivet. That's going to go in this area right here, then there's a hole for the rivet to come through. Then you can add or remove washers from the spacer rivet to tilt the head up or down. It's also going to have a set screw down here, so once you have your hardware installed on the shank and the head assembly holding it on to the shank, you can tighten that down, and that's going to be your set screw.

That is included, it's already going to be installed in the head unit, that way all you have to do is tighten it or loosen it for your application. The head is a fabricated head that's going to be compatible with friction-style sway-control systems. Those systems are going to be sold separately. It's going to come with a welded steel shank. This is going to offer an adjustable height. It can be used in either rise or drop position.

Solid steel construction with a nice black powder coat finish on it, so it's going to last a long time. Now, I took a measurement of it earlier, and I measured from the very back to the very front. We'll just go ahead and do that measurement for you real quick. Very back to very front, that measurements going to measure about 12 inches. That measurement from the center of the adjustable holes here that our head's going to mount into, to the center of the pinhole, that's going to give us a measurement of about 7 3/4 of an inch. This part number does include the shank. Again, it's a nice, solid shank.

It's also going to come with all the mounting hardware that you need to get the head installed onto the shank. You're going to get your washers, you're going to get your bolts, and you're going to get your nuts for that. It also comes with your 5/8 inch hitch pin, as well as a clip. That way you can secure that shank inside of your 2 inch by 2 inch hitch. These right here are going to be our lift brackets. It does feature adjustable spring-bar tension simply by switching the links right here on the chains. That way you can fine-tune your system. It's also going to come with your snap-up lever. This is going to ease the installation by reducing the lifting that's required by the trailer jack. Now, the unit is going to be a complete steel construction. It's all going to have a nice black powder coat finish on it to resist rust and corrosion. It's got the nice powder coated steel. These right here are going to be positioned on the frame of our trailer. We're going to have our installation bolts right there. Then the lift brackets are going to be secured in place using the pin right here. Excuse me, the clip. While these are up, in place, you simply install that clip and that's going to hold that up. The system is going to include everything that you see here on the table. It does require a hitch ball that's going to be sold separately, and that's going to need to have an 1 1/4 inch diameter shank. Now on this unit, when it comes to the maximum tongue weight, we're looking at 500 pounds. The maximum gross towing weight is 10,000 pounds. The unit is designed for 2 inch by 2 inch trailer hitch receivers that are rated for use with a weight-distribution system. The lift brackets are going to take up about 5 inches along the trailer frame, and the area that goes around the trailer frame, that's going to give us and opening of about 3 inches. Now I did mention earlier that this unit can be used in either the drop or rise position. When it's installed in the rise position, the maximum rise we're going to have, with the head assembly installed at the highest setting, is going to be 6 1/2 inches. That's measuring from the inside top edge of the receiver tube of our hitch to the ball platform. If we use this in the drop position with the head assembly at the lowest setting, that's going to give us a maximum drop of 1 1/2 inches, measuring from the same point. Again, we've got the snap-up lever that's going to ease our installation. All the hardware is included, and this is a really nice, solid, dependable weight-distribution system. That's going to do it for our review of part number PS49581.

I have a 2011 Dodge Nitro 4.0 liter compact SUV, which I am using to tow our Mighty Lite travel trailer. I needed a good weight dist. hitch to accomplish handling the 3850 GVWR of the trailer. This system brought up the towing capacity of our Nitro to 5000 lbs., and installs much easier than I expected! We had no sway problems during our 2 journeys with this system so far, even with the high winds we encounter up in the CA. high desert area where we live. My one complaint would be the heavy weight of the solid steel shank which will make you grunt when lugging it out from the shank, but since this hitch is rated up to 10,000 lbs. I guess that is to be expected! Otherwise, My I am VERY happy with the durability of this product, and the price was great. 228819


Comments

The hitch is doing great! Another nice thing about it are the grease fittings provided on the springbar sockets, allowing for quick lubrication of the springbars while hitch is installed. Great price for a great product!

Hitch works better than I expected. It arrived on time and in perfect shape. If I had a complaint, it would be that the instructions are a little vague and the list of needed tools is wrong. I happen to have the experience and tools to interpret the instructions and install it correctly, but first timers should really have it professionally installed. It's a safety thing. 285660

This system was used with a RAV4 and a 14 foot tow behind camper. I would give 5 stars regarding the system's intended performance for weight distribution. My one reservation related to the requirement to jack the tongue up so high in order to reach the desired chain link. With one less link we experienced times when the lower end of the arms/U bolts dragged when going over things like speed bumps. 312908

Review from a similar Pro Series RB3 in Weight Distribution


I've always received great service from eTrailer and this transaction was no different. Having owned 5th wheel trailers in the past I had no experience with weight distributing hitches. I had a sales rep from Hensley trying to convince me I needed their $1700 set up but I liked the price of the RB3, however the adage, "You get what you pay for" was nagging me. My wife was also nagging me about spending $1700 on a hitch and since I like sleeping indoors, I went with the RB3. Tow vehicle - 2000 Ford Expedition 4x4 Eddie Bauer. 5.4l and factory towing package. Rated for 6800lbs Trailer - 2014 Dutchman 275. 27.5' no slides, empty weight 4618lb, gross 7800lbs, average towing weight 6000lbs I contacted the eTrailer techs to figure out what I needed capacity wise and placed my order. Hitch was shipped promptly and to my surprise was very well packaged. The cardboard box was robust. It was taped, stapled and strapped well beyond UPS's ability to destroy. Inside the parts were secured in fitted foam pockets so the paint was not damaged. All the parts were well painted and fit together correctly. The RB3 is stout and well designed. My only brief scare was the owners manual. The part number on the manual indicated I had received the lighter duty hitch however when I double checked the part numbers on the components, I had received the correct product. The instructions were clear and I had the hitch assembled and set up in about 2 hrs. Hitching up is simple once all the settings are dialed in. We went on a 900 mile maiden voyage that involved freeways with brutal cross winds, very steep mountain passes and narrow winding forest service roads with huge washouts. The hitch performed perfectly and I was impressed how well the Expedition-Dutchman combo performed. I didn't order the optional anti-sway and one time on the trip for about 5 miles we had an extreme crosswind that pushed us around and I had to slow down to 40mph. I blame that more on my Load range C tires on the Expy than the trailer pushing us. In checking on the Expedition forums, the consensus was Load range E tires would fix the sway problem. 210210

Review from a similar Pro Series RB3 in Weight Distribution


Can't speak highly enough of eTrailer.com's customer service. I had accidentally ordered the incorrect product spec for my setup (2015 F150 towing a 8.5x20 ATC toy hauler) and they were able to get me the correct product within the same week and provided an easy process for returning the incorrect hitch. Regarding the hitch itself, installation was a breeze, though I had to get a couple new tools due to the standard sizing of the nuts bolts, rather than metric. It would be very helpful if the instructions posted online would have a required tool listing with specific sizes required so you can be prepared ahead of time. After installing the hitch and taking initial measurements, it was very easy to fine-tune to get the setup perfect. Before installing the hitch, my truck would sit nearly 1.5 inches higher up front and 3 inches lower in the back with the trailer hooked up compared to stock, with very light steering feel when going down the road. With the hitch installed and dialed in, the front sits back at the stock height and only 1.75 inches lower in the rear, creating an essentially flat ride profile, and the trailer itself is perfectly level. Riding down the road the difference in feel is amazing. Much better steering response without the "light" feeling, tracks much more planted when going down the highway, and bumps and undulations in the road surface are absorbed much more smoothly now that both the truck and the trailer are sharing the workload. 322233

Thanks so much for your business and review, Ryan. The required tools for installation are listed in the upper left-hand corner of the instructions.

Great WD hitch - Great price- Prompt Shipping. Instructions were easy to follow, worked perfectly the first time. Night and day Towing experience. 2003 Suburban towing 21' keystone Hideout 3750 lbs, with tw of 600lbs the truck has soft OEM spring set up, and sits low already. First added air shocks to get rid of the sag, but the addition of the WD hitch made all the difference, before WD had to run 140lbs of pressure just to maintain ride height, now I only run 40lbs in shocks now and she sits perfect, not to mention Steering is normal and all the jerky pushing and pulling is gone its nice and smooth now. 185252

Review from a similar Pro Series RB3 in Weight Distribution


Installed this product on a livestock trailer in about an hour. The installation is fairly simple, however, you'll want to take your time to make sure you have the ball at the correct height and angled down (or up) so that your spring bars are level. This may take a few steps of trial and error but once you set it right the first time, you won't need to adjust it for every use. I orginally purchased the trunnion bar style, but because my coupler on my stock trailer is approximately 3 inches higher than the A-frame, I needed to get the round bar style so that I could have additional clearance between my bar and the frame of the trailer. Now I can run 6 links between the two and everything sits level. A weight distribution hitch allows me to now pull 10,500lbs, where I could only tow 5,000 without one. A good product at a good price. If you only need it for recreational towing, this product should be more than capable. 135034

Great product easy to install except I had difficulty determining whether or not both conical washers went on the top bolt; I just assumed another had to go on the bottom but the picture clearly shows both go on the top bolt. Once I figured that out the rest of the installation went without a hitch; no pun intended. The video I viewed a couple of days before helped immensely with the installation. Great price and tremendous free/fast delivery via UPS. Have ordered other products and each time no problem even with a return on one of them. Thank you E-trailer! 161426

For ten years I was an RV delivery driver and used etrailer for equipment. Now I'm an RV owner and in retirement, again using etrailer. We have downsized from our dually diesel to an F150 EcoBoost and no longer pull monster 5th wheels, but have a nice Airstream. From experience I would never pull anything without a weight transferring hitch and again from experience this Pro-Series is one of the best. Great equipment, great prices, great fast delivery etrailer always gets our business. I've already ordered again. 182637

Review from a similar Pro Series RB3 in Weight Distribution


Instructions with this unit were good, although jacking the tow vehicle with the trailer attached up 8-12", in order to ready the weight distributing hitch for attaching the chains, seemed excessive; practically lifted the rear of my SUV off the ground! I may need to call customer service about this. For now I only have used the hitch to move the trailer to storage; I'll have to repeat the setup once the SUV and trailer are loaded for camping. The hitch seemed to allow nice steady towing for that short distance. 178247

Review from a similar Pro Series RB3 in Weight Distribution


The hitch does a very good job of redistributing the hitch weight. I have an extended (12") shank so I can open my tailgate, and the hitch helps overcome this. The only problem is disconnecting the spring bars. The retaining pins for the spring bars have a very small flange to grip when pulling the pins to release the spring bars, and it can be hard to manipulate. Other than that, I am very satisfied with the hitch. 265515

The only problem I encountered on the installation of the head was getting the washers on the rivet. Fingers too big and area too small, plus having to take the thing apart several times to get what seemed to be the best position for the spring arms in relation to the trailer tongue. Will be making a two thousand mile trip beginning tomorrow, hope is all works as good as advertised. 324726

This system worked out pretty well for me. Initially, I had it installed and adjusted by the RV dealer.

  • We are happy to help you with your selection of a new weight distribution/sway control system for your 23-foot 8500-lb travel trailer. The key starting point to choose a new system is a measurement of your trailer's fully-loaded and ready-to-tow tongue weight. Dry trailer weight, in your case 8500-lbs, is important too, but the actual measured tongue weight when the trailer is loaded and road-ready is the key factor when to selecting a new system. A system rated too low will not deliver...

  • Pro Series RB3 Weight Distribution System Recommendation for Trailer with 393 lbs of Tongue Weight
  • If your loaded tongue weight is 393 lbs when you are ready to tow the RB3 part # PS49581 would be a great option as it has a tongue weight range up to 550 lbs. If you need more tongue weight range you would then want the part # PS49582 which goes up to 750. For a 2 inch ball you would want part # A-90 and for a 2-5/16 inch ball # 19286.

  • Recommended Weight Distribution Hitch for a Ford F150 Towing a Jayco Jayflight Baja 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. The Pro Series weight distribution hitch # PS49583 you referenced will be more of an overkill because the tongue weight won't be high enough on a 3,200 pound trailer. The two I recommend are the Pro Series...

  • Weight Distribution for a 2009 Honda Pilot and 3,000 Pound Travel Trailer

However if it states it could be used it is just not recommended then I would contact a Honda dealer to get further input. If you determine that weight distribution can be used then you will need to go by the tongue weight of the trailer when loaded and ready to tow plus the weight of anything loaded behind...

  • Can You Back Up with a Pro Series RB3 Weight Distribution System Installed
  • In general weight distribution systems don't like tight jackknife turns that you can get yourself into when reversing a trailer. The Pro Series RB3 Weight Distribution # PS49581 that you referenced is no exception to that. If you are backing up mainly in a straight line this system would work great for you. If you will end up in a tight turn you will need to remove the spring bars. I attached a link to a help article for weight distribution systems for you to check out as well.

  • Most likely the Pro Series RB3 weight distribution system part # PS49581 would work well based on the dimensions you listed since this system is designed for tongue weights up to 550 lbs. I can't imagine your tongue weight would end up being more than that, but you do need to consider the weight of any cargo behind the rear axle of the tow vehicle as tongue weight. If you do need to go with a higher rated system the part # RP66541 is good for up to 800 lbs of tongue weight. I attached...

  • Weight Distribution System Recommendation for a Trailer with 350 lbs of Tongue Weight
  • You want to pick out a weight distribution that has a tongue weight range that matches up well with the tongue weight of your trailer. Getting a system rated too high will result in an overly stiff ride, and if you go too low the system won't distribute any weight to the front axles. Right in the middle is ideal.

  • Should Weight Distribution be Used on a 3500 Pound Trailer and 2004 Jeep Grand Cherokee
  • We recommend using weight distribution if either of the following situations is true: First, weight distribution is a good idea if the gross trailer weight is at least 50 percent of the gross vehicle weight. Or second, if the trailer causes the rear end of the vehicle to sag. A trailer weighing 3,500 pound probably is at least half the weight of your Grand Cherokee so it would not be a bad idea to use weight distribution. But I can do better on price.

  • Selecting a Weight Distribution System for 2002 Ford F-150 Towing Trailer of 5000-lbs Fully Loaded
  • Step one is to confirm that the hitch on your F-150 is rated for use with a weight distribution system. This will be indicated on its safety/warning label. Next, selection of a properly-rated weight distribution/sway control system for your trailer requires that you take an accurate tongue weight measurement of the trailer in its typical fully-loaded condition just as it will be when towed. Trailer tongue weight is usually 10-15 percent of the trailer gross weight, but the type of trailer...

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 just like you did. The gross trailer weight capacity does not affect the spring bar tension on the system you choose so having one rated for 10,000 pounds will not be a problem at all. Since the total...

  • Air Bags or Weight Distribution for a 2008 Mitsubishi Outlander Towing 1,500 Pound Boat Trailer

You can leave the air pressure the same with or without the trailer hooked up. You may notice a stiffer ride though when not towing because the tongue weight of the trailer will not be compressing the air bags or suspension. The best solution for sag caused by a trailer is to use weight distribution. On a boat...
