Pro Series Weight Distribution diagram

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 Pro Series Round-Bar Weight Distribution

Pro Series Weight Distribution adjustable head from top and side

To adjust your weight-distribution head assembly to the correct angle, insert the included rivet and up to 8 washers into a 1/2-inch hole in the "U" on your head assembly. Use the smallest number of washers necessary to achieve the correct downward angle for the spring bars. Each washer lowers the chain ends of your spring bars by approximately 1-1/2 inches. Once the correct angle is reached, use the included bolts, serrated washers and nuts to lock the unit into place.

Pro Series Weight Distribution round spring bar locking devices

The round spring bars of this system slide up into the weight-distribution head and are secured with built-in, spring-bar locking devices for quick, easy installation. With a tapered design and forged steel construction, these bars flex to ensure a smooth, controlled ride for both your tow vehicle and your trailer.

Friction Sway Control

Pro Series Weight Distribution friction sway control installation on trailer framePro Series Weight Distribution friction sway control installation on hitch head

The integrated friction-style sway control of the Pro Series system reduces trailer sway caused by winds, winding roads and sudden maneuvers. As soon as your trailer begins to move out of line, the friction pads inside the unit touch one another and create resistance to help prevent further side-to-side movement. To install, simply bolt the sway-control ball plate to the A-frame of your trailer and attach the other end to the included ball, which mounts on the head of your weight-distribution hitch - drilling required. The ball plate mounts to the side of the trailer frame so it will not interfere with gas tanks, toolboxes or generators.

Video Transcript for Pro Series Weight Distribution - WD With Sway Control - PS49902 Review

Today we are going to be taking a look at part of our PS49902, this is the Pro-Series Weight Distribution System with Friction Sway Control. It's rated at 10,000 pounds of Gross Trailer Weight and 750 pounds maximum tongue weight. This unit is going to evenly distribute the tongue weight to the axles of the tow vehicle and trailer for stability and control. Ultimately it's going to create a more level ride for both the tow vehicle and the trailer. Now this one comes with the Friction Sway Control, that's going to reduce sway caused by winds caused by winds, curving roads and sudden maneuvers. This is going to be the main portion of the Sway Control System. You're going to have the adjustable tension bolt that's going to let you create the perfect degree of control and resistance.

You're also going to have the integrated handle, this is going to engage and disengage the sway control system. It's easily removable. It's going to be held on in two locations. You have got the socket on this end, this is going to connect to the ball right here and it's going to be held in place using the clip. Then you are going to have the socket on this end, this is going to engage the ball right here and this plates going to be mounted onto the trailer frame.

That's going to be held in place with the other clip. The bracket's going to be held in place using these six screws right here. It's a really easy system, so that way when you need to remove it, all you have to do is release the two spring locking pins and simply remove the friction sway control system from your setup. Now, as soon as the trailer begins to move out of line, the friction pads inside the system are going to touch one another and it's going to create resistance, that's going to help prevent further side-to-side movements so it engages automatically and right off the bat. You can control the level of intensity by setting the screw right here and you can disengage and engage the system by using the lever. It's also going to come with the round forged steel spring bars, these are going to have a tapered design for superior flexibility, they are very strong and durable. The bars are going to flex appropriately over uneven terrain for a nice, controlled, even ride.

You can adjust the spring bar tension by switching the links in the lift chains to fine tune the system. These are going to be called the Lift Brackets, that's what that lift chains are connected to and that's going to attach to the frame of the trailer as well. It's got the set-screw on the back, that way you can easily get it installed on the frame. One other thing I want to mention is the head right here. This is the head of our weight distribution system. Our spring bars go up in here and they engage.

That also allows for easy maintenance because on each side you are going to have a grease fitting, so you can pump that with grease and that way it's always going to keep the system operating as it should. You can also tilt the head of the system by adding washers to a rivet inside the weight distribution head. The rivet's right here, it simply goes in, there's a small hole that the rivet sits in . I didn't install it because I wanted you to be able to see it and it's got all the washers right there. Each washer is going to lower the chain ends of the spring bars by approximately an inch and a half, so once you have the correct angle for your particular set-up, all you have to do is use the included bolts. There is going to be one right here and two right here that hold the distribution head onto the adjustable channel, or the adjustable shank. Tighten everything down once you get the correct angle and it's going to hold everything in place to best suit your application. That's also going to come with a solid steel shank, this is neat because it's an adjustable shank - solid steel construction. It's going to be powder-coated for rust protection. The other thing it's going to come with is this bar right here, this is our lifter handle. This is going to help gain leverage to engage or disengage the lift bracket adjustments. Once tension is applied, it can be really hard to adjust the tension and get the brackets in position, so they include this bar for leverage, it goes over that portion, that way you can engage or disengage the lift bracket adjustment and position up or down. A few specs with this unit: The tongue weight is going to be 550 pounds to 750 pounds, that's the max. Gross towing weight is 10,000 pounds. The adjustable shank is going to fit into a 2 inch x 2 inch trailer hitch receiver that's rated for use with the weight distribution system. Our shank length is going to measure about 12 and a half inches. When used in the "rise" position, it's going to give you a maximum rise of 6 inches and a maximum drop, in the "drop" position, of 2 inches. The lift bracket width is going to take up 5 inches on the frame of your trailer. They're going to need to be centered on the trailer frame 30 inches from the 2 and 5/16 inch hitch ball. This 2 and 5/16 inch hitch ball is going to have a 2 and a half inch shank length and a shank diameter (that's just the threaded portion) of an inch and a half. A couple things to keep in mind with this system is that the weight distribution system cannot be used on trailers with surge brakes and the Friction Sway Control unit must be removed when you are going to go in reverse. It's going to come with everything you see here on the table. This is the only piece I haven't talked about. This is the shim that can go in between here to take out any additional room you may have. Sometimes it's used, sometimes it's not, it's just going to be dependent upon your particular application. That's going to do it for our review of part of our PS49902, this is the Pro-Series Weight Distribution System with the Friction Sway Control. .

As a strong Believer in the Easy Lift hitches and saw controls on our last trip to South Dakota we hit some unexpected snow on a blind hill and the sway control save me from a what could have been a very bad skid.In the 1960's and 70's I was a Easy Lift and Reese dealer and installer so I have very high regards for these products I try to express to people never pull a trailer without one of these hitches. 711851

Trailer hitch was well packaged and delivered quickly. High quality. Installed quickly. Plan on using it soon. As a side note, I just ordered another product that was priced at 1/3 of the cost on the big website that sells everything for the exact same product. Can't wait to get it. It is a connector/conversion set in order to use a portable grill with my RV. 633584

I pull a 26' TT with a 2005 Chevy Tahoe Z71. I called Etrailer and the tech helped me decide on this WD system. It took me an hour or so to get it installed correctly, but it has worked great since day 1. I also got the sway bar and I can tell a huge difference with it. Great product and great service! 603861

Seems to be very high quality will known after the 4th of july will take trailer out for a trip this hitch was easy to assemble and set up would recommend it for any one looking for a load leveling trailer hitch shipped fast also 526575

I would have given it 5 stars if the installation instructions were more thorough. I watched the videos on the website and that made it easier. Everything was included for installation. Not many people will have 11/8" sockets which are necessary for the main bolts. I am going to drive it a while before deciding about the sway control. Our trailer only weighs 4500 # empty so should be fine behind a Silverado 1/2 ton 4x4. 523895

- PS49902

The WD system is doing what I wanted it for so far. I haven't had it on for very long but I can tell it made a huge difference. The sway control is still waiting for me to attach the mount but I think it'll be a-ok as well. 522323

To date, this trailer hitch has performed flawlessly over approximately 5500 miles. It will be on the road again in a couple of weeks for a short trip up to Las Vegas to visit friends & celebrate our grandson's 21st birthday. I would recommend this hitch, or its bigger brother if your trailer is heavier, to anyone. It is currently used to tow our 25' Apex trailer. Sorry I don't have any pictures. 493235

This was our first experience with a pulling a camper. Everyone said we needed this. Bought it and it was easy to install with your very well made videos. This hitch works great. Since then i have purchased mirror extensions and a complete wiring harness. Your videos are great. Keep up the good work. I tell everyone to go here for any trailer needs. Thanks again 478213

It is my first time hauling a trialer this size. The instructional video is fantastic made it easy to hook up, had it hooked up and driving home with our new trailer in less then an hour. 430771

Product installed easy, looks to be heavy duty. I will find out in a few weeks when we take it on the road.etrailer has been a great company to order from. 425783

- PS49902

I just got the WDHitch system installed today, but I haven't taken it for a test drive yet. Once I got the trailer on level ground it took me almost 2 hours to get it installed correctly, and I'm still not 100% sure I've done that. I will say that it would be helpful if the videos or product page included a section in the beginning outlining all the various tools you will need to do the job. He does mention some of them in the video, but not all. For instance - if there is a certain kind of drill/bit that will drill through the trailer metal better than others. Also the size of the rachet needed for the screws that mount the friction ball to the frame. He mentions it throughout the video, but it would be nice to have a checklist up front. Overall I am very pleased so far. 421059

- PS49902

I have been using this for a year now. Once you have it setup correctly it is a great WD hitch. I have had no problems with it and I am sure I will be using it for many seasons! 361031

This product has worked very well for me. I originally ordered a hitch that was too heavy duty for my trailer. Etrailer was great and worked with me to make sure I got a new hitch that would work for my needs. No I have the product that I needed. Thanks! 338390

i have used this weight distribution system time after time and would recommend it to anyone to get one. It makes your control so much better. 332482

  • Weight Distribution Installation for Pole Tongue Boat Trailer Towed by 2005 Ford F-150
    Thank you for the photo of your truck and hitched boat trailer. There are a couple of things to keep in mind concerning tongue weights (TW) in your setup. First, typically a boat trailer can have low-ish TW due to the rear-positioned motor's weight lifting the trailer tongue. When placing tanks, toys and other items in the boat for transport you want to do so such that you can maintain a suitable amount of TW, 10 to 15-percent of the boat/trailer combined gross weight.

  • Recommended Longer 2-1/2 Inch Shank for a Pro Series Weight Distribution System
    The Curt Weight Distribution Shank part # C17132 will work with the Pro Series Weight Distribution System part # PS49902 so if this is what you need then you will be good to go. However, the 8" drop that the above offers is quite long and if you don't use all of this then the shank might limit your ground clearance. If you only need 6" per say of drop then I would go with the Equal-i-zer Weight Dist Shank part # EQ90-02-4900 instead. In order to find out how much drop you need, simply...

Which a 4,140 lb trailer would have no problem with.The Pro Series Weight Distribution System part # PS49902 that you referenced would be a great option too since it has a tongue weight range of 550-750 lb and your tongue weight is 560 lb.

  • Weight Distribution for a Trailer with Varying Tongue Weight from 400 to 1,500 Pounds
    No worries, I can help you out with this issue. It is a common question, a varying load. There are weight distribution systems that have a tongue weight capacity range. The widest range is 600 to 1,200 pounds. There is also an 800 to 1,500 pound system. Considering that you can potentially have 1,500 pounds tongue weight you will need a system that goes at least that high.

  • Backing Up Trailer While Using Pro Series Weight Distribution System with Friction Sway Control
    Pro Series does not recommend that you back up your trailer while using the Pro Series Weight Distribution System with Friction Sway Control, # PS49902.

    You are correct that weight distribution (WD) spring bars of the same type from the same maker are often interchangeable and this allows a given WD hitch system to be updated with bars of a different capacity to accommodate a lighter or heavier trailer. The Pro Series systems # PS49902 and # PS49903 both use round spring bars of the same design and for instance 1000-lb bar set # PS58441 could be used to upgrade system # PS49902 to give it the same capacity as # PS49903.

So all in the same ball park. Trailer tongue weight is usually 10 to 15 percent of the gross trailer weight so you are looking at least 688 to 1,063 pounds of tongue weight and that is with nothing loaded in the trailer, no propane or water, and so on.

  • Friction Sway Control Bar Making Groaning Noises After 4 Years of Use
    It sounds like the friction sway control bar needs to be cleaned. All you have to do is remove the slide bar from the unit and clean off the friction surfaces with a wire brush. You may also need to blow out the inside of the unit to clear out any crud stuck inside. This is also a good time to inspect the unit for damage and excessive wear. If you determine that you need a new one they are very reasonably priced. You would need # 83660.

  • What Happens if Trailer Tongue Weight is 500lbs and Weight Distribution System is Rated For 1000lbs
    Some weight distribution systems have a tongue weight capacity range and if the tongue weight is in that range it will still be effective. If the system is only rated for 1,000 pounds and there is no range and you have 500 pounds on it you will experience a stiffer ride and it will not be as effective as it could be. In extreme cases the trailer can get damaged because the spring bar tension is so great compared to the weight of the trailer. But you should not be concerned about that...

    The weight distribution systems that use a simple friction-bar for sway control, such as the Pro Series # PS49902, cannot be backed up until you either release the tension on that friction arm's hand control or simply disconnect it entirely. These simple friction devices can help with trailer sway because their friction works to stop the swaying motion of the trailer.

    With a weight distribution system you can back up straight with the bars installed, but if you are going to get into a tight, jackknife like situation you have to disconnect the spring bars as they aren't designed to turn very far in the head of the system. If you leave them in they will fall out or break something.

  • Weight Distribution & Sway Control System for V-Nose Trailer with Limited Frame Access for Brackets
    A trailer with accessories like propane tanks up front or with V-nose construction like yours can make it more challenging to install a weight distribution (WD) system. WD spring bar brackets typically need to mount 25 - 30-inches behind the hitch ball. For example, the system you referenced, Pro Series # PS49902 requires placement of its brackets 30-inches from the center of the hitch ball. This problem is not too uncommon and fortunately a solution exists. Reese offers their bolt-on...

  • Where To Measure the Hitch Height on a Trailer When Setting Up Weight Distribution
    In the video you referenced Joe (the installer) first gave the height of 24 inches when he measured from the ground to the top of the coupler on the trailer. When he later mentions 22 inches he is referring to the the distance from the bottom of the coupler to the ground. I realize that's a bit confusing but that is why the two numbers are stated. Typically when determining hitch height for ball mount selection you want to measure from the ground to the bottom of the coupler. Either...

  • Recommended Weight Distribution System for Towing a Trailer with 270 lbs Dry Tongue Weight
    The Pro Series Trunnion Style Weight Distribution Kit # 49586 actually could very well be the correct fit for you. When you are choosing a Weight Distribution (WD) system you want to use one that has a Tongue Weight (TW) range that the Total Tongue Weight (TTW) of your setup falls in the middle of. You can find your TTW by adding the TW of your fully loaded and ready-to-go trailer along with the weight of any cargo behind the rear axle of your 2015 Nissan Xterra, like a cooler. Keep...

  • Upgrade Pro Series 750 lb Tongue Weight System to 1,000 lbs Tongue Weight
    If you are looking at 960 lbs of tongue weight a 750 lb rated system like the part # PS49902 is going to be ineffective. If you are sure you wouldn't exceed 1,000 lbs you would need the part # PS49903 instead. This is the 1,000 lb tongue weight system. To upgrade your Pro Series part # PS49902 to a setup with a tongue weight range of 750 to 1,000 lbs you would need to change the bars to # PS58441. These will simply replace your current bars and you would be good to go.

  • When to Loosen and/or Remove a Friction Bar Sway Control on a Trailer
    Ideally you would loosen the sway bar and then remove it by lifting it off the vehicle end ball and unpin it from the trailer side. It only takes a few seconds and doing so will prevent damage to it and the trailer when backing at an angle. The instructions, which I have linked for you to view, specifically say the following: On some installations, damage to the sway control may occur during extremely sharp turning maneuvers. This can be checked by slowly backing vehicle into a jackknife...

  • Weight Distribution Recommendation for a 7,000 Pound Aluminum Car Hauler Trailer
    I am glad you mentioned that the tag states you can use weight distribution. With aluminum frame trailers people often have to call and ask if such a trailer can be used with weight distribution. But we can skip that and get to the next step. When calculating tongue weight for weight distribution you will also need to add the weight of anything loaded behind the rear axle of the tow vehicle. Typically trailer tongue weight is 10 to 15 percent of the gross trailer weight. On a 7,000 pound...

  • Upgrading to 1,000 Pound Spring Bars on a Pro Series Weight Distribution System
    Yes, you can use the 1,000 pound sporing bars, # PS58441, with the same head that came with weight distribution system # PS49902. These spring bars are rated for 750 to 1,000 pounds tongue weight. If your total tongue weight does not fall within the 750 to 1,000 pound range then these spring bars will not be effective. I have included a link to a help article on determining tongue weight for you.

  • Weight Distribution Recommendation for Jeep Wrangler Unlimited Towing 17 foot Casita Travel Trailer
    As a first step, you'll need to determine the fully loaded and ready to tow weight of the trailer. The 2012 Jeep Wrangler Unlimited is rated to tow a maximum of 3500 lbs. Using a Weight Distribution system can increase the towing capacity of the hitch itself, but it CANNOT increase the towing capacity of the vehicle. If the fully loaded weight of your Casita TT exceeds the 3500 lb towing capacity of your vehicle, I can't recommend you tow the camper with that vehicle. If however,...
