Featuring friction sway control, this weight-distribution system includes an adjustable shank, and its flexible, powder coated steel, round spring bars create a level ride for both your trailer and your tow vehicle. Fits 2" trailer hitches.
|Included w/ PS49903||Optional Add-Ons|
Note: This weight-distribution system cannot be used on trailers with surge brakes. The sway control must be removed when you are going in reverse.
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.
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.
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.
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.
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.

Today in this trailer, we are going to install part number PS49903. First step is to go ahead and get our truck and trailer in straight line, then well disconnect the truck and trailer and then well go ahead and level off the trailer then we can start work on the weight distribution and our measurement from the top cup down to the ground is going to be 20 inches. Well write that down and then we will go on to the truck. At the top of the fender well at the rear axle is going to be 37-1/4 inches and at the front axle to the top of the wheel well will be 34-7/8. Ideally, we want the front to stay the same and maybe have the back settle about an inch at the most. Now this obviously will vary from truck to truck and from truck and trailer combinations.
To start off our install well go ahead and install the shank into the hitch. Well install pin and clip to secure it. First, well mark off our height that we need to set the ball at and account for vehicle squat we are going actually raise the ball up one inch. Then well install the head assembly with the ball already installed onto the shank and well match it up to that mark as close as possible. On the inside of the head, theres a pin that we had to add some washers to that will provide tilt for the head assembly to go back towards the trailer and apply pressure on the spring bars.
Now this will vary from trailer to trailer and vehicle to vehicle. We are going to start off with four washers. Well go ahead, and bolt the head assembly to the shank and then loosely install all the hardware. Now well tighten up the bolt at the bottom that way to help bring the top of the head of the assembly up snag against the shank and provide the proper angle we need. Then we go ahead and tighten down the bolts that go through the shank and the head assembly.
Well tightened them and torque those down as specified in the instructions. With our trailer back on the hitch, ball well go ahead and raise the truck and trailer back up and then we can go ahead, and install one of the spring bars and then line up the chain bracket. To install the spring bar we will go ahead and slide it up from the bottom, make sure it clicks in the place and then well take our chain thats already been installed in the spring bar and pull it up vertical in a straight line and then align our bracket with it. Once we have the bracket and alignment in chain well go ahead and tighten down the snap up screw on the backside. Well do that on both sides.
At this point, well go ahead and attach our spring bars to the snap up brackets we just installed. Well go ahead and lower the yoke on the snap up bracket until its parallel with the ground and slipped the closest link over to the hook and when we do this we want to keep at least five links between the hook and the u-bolt and then well go ahead and check to see how the spring bars are properly aligned with the frame. Now you want your spring bars pointing slightly down or level with the frame. As you pointing up again well have to take the head assembly apart, add some more washers and tilt the head assembly down then reassemble. Once we have, the chains hooked up well go ahead, and lower our truck and trailer and check our alignment with the spring bars with the frame. With every thing hooked up, well go ahead and check measurements again like we did at the beginning. It looks like the front axle stayed about the same and the back axle settled about one inch which is about right. So that all looks good now well go ahead and move on to the installation of the anti-sway control. Now we took the sway ball and mounted it up to the side of the frame temporarily. So, well go ahead, and measure up and make sure they stay at the correct spot. We are going to measure from the center of the hitch ball to the center of our sway control ball it does come out to the right measurements, 24 inches. However, two of the boltholes going towards the back trailer do not line up properly. Once you are going to reinstall the old sway ball in its place. However, when you install the old anti-sway ball we will sue new hardware. Well take the self-tapping bolts and the star washers, attach them and then reinstall them into the trailer frame. All right now go ahead and add on the anti-sway bar. Well apply a little of grease to the mounting points. Well go ahead, and add the sway bar on top and install the safety pins and after that all we need to do is go ahead and take it to the test drive, make sure everything works properly and if the sway control doesnt get into a bind on sharp turns. That will finish it for our install part number PS49903.

The product was of high quality and cheaper than i could find in local stores. The free shipping on this item due to price made the choice a no brainer. All items shipped complete with instructions and on time as promised. The tracking information was very helpful and precise. I will be happy to order other products from e-trailer in the future. 78874

I did extensive research on the product before buying; got, by far, the best price from etrailer and with free shipping, it was a no-brainier. Shipping was lightning fast, delivered right to my door with everything in perfect condition. This is my fifth time buying products from etrailer and I have been 100% satisfied every time. You definitely can shop with them with confidence; I highly recommend them and simply will not shop anywhere else for my towing needs. The Pro Series set-up is perfect for towing my 5000 lbs travel trailer with my 2009 Chevy Tahoe; it creates a safe even tow that you can immediately feel especially on the interstate at higher speeds. Set up took a little while but the online video gives easy step by step instructions that guide you through the process. The product is very rugged and has top notch quality comparable to other models at double the price. Awesome product, great price, fast shipping, excellent customer service; simply a perfect transaction. Thank you, etrailer! 93171

I ordered this product based on the ratings primarily. I had planned to be at my in-laws two hours away from home for a few day, happened to be the same town that I purchased my new camp trailer in. I ordered the hitch and chose to have it shipped there, thinking I would intercept it, install it, and pull my new trailer home with it. Turns out delivery took longer than I anticipated (not longer than etrailer quoted so my own fault). I was able to call customer service, and have them re-route the delivery to my home. Way to go ETrailer!! Installation was a bit tough at first trying to go off of the dismal directions provided by the manufacturer. I jumped on etrailer.com and found a video on installation of this exact hitch. It was just what I needed, and installation was a snap after that. Excellent product, very robust, and I was surprised at how much difference the hitch made in the squat of my 1/2 GMC pickup. I definitely needed this hitch for safe towing of my 22' 4400lb camper. 136148
We originally drove our new trailer home using just a regular ball and hitch. My husband drove the trailer home I followed in our car. Oh my that was a scary sight to watch. It was far from level. In fact it was more of a V shape between the two. Because this is our first travel trailer, we had never heard of a weight distribution system. We scoped out websites and watched many YouTube videos. We both agreed the Pro Series WDS with FSC was the ticket. It also was much more affordable that some we looked at. We read the instruction but what was more beneficial was the videos from etrailer.com Wow what a difference in the ride. Its interesting to watch other TT go down the road, some are not properly installed. Darn. If we ever get the chance to talk to others we will recommend the etrailer.com and for them to watch the video. GREAT PRODUCT GREAT PRICE!!! Way-to-go guys you did a great job! 95706

Customer service knew all the right questions to ask and kept me from ordering the wrong hitch. The shipping was really fast, I ordered on wednesday at noon and it was at my house when I got off work on friday. 35219

I ordered this product with free shipping. About a week later it was on my front porch. Everything was in the box with ok instructions. I was replacing another similar unit and knew how to assemble it, but the instructions are not clear on how to properly adjust the sway control. I did a shake down drive, made a few adjustment and left on a thee month trip with my 30' travel trailer. I have now traveled about four hundred miles with the new Weight Distribution System and it is much superior to my older system. The only reason I do not rate it EXCELLENT, is the poor assembly and adjusting brochure that came with the unit. Watch the online video on assembly which is more informative. Would I buy from etrailer again, YES I would. The product was everything they said it would be. 88281

Great hitch for the money. I pull a 6500 pound travel trailer with a Yukon Denali and it tows beautiful even with out the sway control. Using the provided instructions I was able to get everything set up properly in about an hour and two tries of hooking everything up before I finally torqued everything. I wish the snap up brackets had a little more hook on them to hold the chains in place while snapping them up, sometimes they fall off when prying up on them. Another complaint was that the sway control plate that mounted to my trailer was missing, but chances are this won't happen to you. I contacted E-trailer and that same day the part was shipped to me at no cost. E-trailer is great I have only positive things to say about them. 50009
This is a very good quality product and a breeze to install. I would use this style load leveler for any trailer application of 5,000 Lbs. it tows my new 30' Arctic Fox travel trailer like a dream. 79514

Customer Service when ordering was very helpful and knowledgeable of the product. Delivery was fast and arrived in good condition with all parts. Installation was easy for the most part with the exception of the torque requirements and the proper tilting of the head. I took me approximately one hour and fifteen minutes to install and level. The test ride was great with no more bouncing and bucking. This was installed on a Chevy Silverardo 2006 long bed and a 2013 26foot Skycat. I would buy from and recommend e trailer.com.

My package arrived as scheduled and ,boy, was I surprised when I bent over to pick it up...Believe me, this baby is WELL MADE! The step-by-step instructions are easy to follow, but you should set aside about an hour to an hour and a half to complete the installation. I have not had a chance to evaluate the hitch on the highway yet, but do not expect any surprises or disappointments. This product appears to be WELL WORTH the bargain price. I highly recommend it to anyone who is about to tow. 137556

After checking and finding that local RV dealers were selling this WD hitch from $470 to $500 and finding the same hitch on etrailer for less with sway control and free shipping I couldn't go wrong ordering it. Great customer service and the hitch is extremely well built and sturdy. I would recommend this product to anyone who is looking for a quality weight distribution hitch at a great price and from great online service provider. I will be doing future business with etrialer.com for sure. 114515
First off 2 thumbs up for customer service. I called and received excellent advice helping me choose the right wdh. Just used for the first time this past weekend. It made a big difference in stability and sway control. I pull a 26 foot travel trailer with my 2013 F150 supercrew. Before it was quite bouncy, but the wdh really does a great job. Took about 45 minutes to setup. Instructions are pretty good and I found a video on youtube for this specific model. Highly recommend etrailer.com. 131437
by: Jeff D.08/18/2012
Couldn't believe the customer service from etrailer, got my hitch 2 days after I ordered and the quality of the equalizer hitch is top quality also. pulled my car trailer to the track and it pulled like a dream , no more bouncing up and down any more. Well worth the money which I might add is half the price of any local dealer around here. Directions of installation kind of sucked but the video they have was excellent. Great Product . Going to order air bags system this winter. 52193
by: Jerry T05/08/2013
I just installed the weight distribution hitch last night. It seems well made and of excellent quality; however, the installation instructions were poorly written at best. I had to back up and start over a couple of times. And that's after reading the instructions at least twice and watching a "not too well done" utube video. Overall I would recommend this hitch to anyone that has a little mechanical ability and good skills for reading between the lines. 79375

I purchased this WDH and installed it myself because the dealer wanted $250 (quoted two hours). I had to drive a few hours to the dealer and install the WDH on the lot myself. After studying up on the great install video from etrailer and instruction guide, it took me no more than 45 mins tops to install! Etrailer shipped it fast and had zero problems. Been purchasing things from them for a few years now. Highly recommended. 56703
by: Barbara & Casey Anderson11/12/2013
Thank you. You delivered just as you said you would and the quality is there although I thought it was made in the USA but it is marked Japan. I looked at it wrong and thought I had a problem and when I called I talked to the person answering the phone and he talked me through to so me I was just fine. What a relief. He was really good although I was rather brisk with him. I apologize and thank you for your service. 107127
I debated between the equalizer and this hitch. I went with this because the price was less than half the price of the equalizer. I was extremely happy with the purchase. It is complete kit, seems very durable, and it has performed flawlessly on my first few tows. The only con if any is the hitch assembly is heavy. E-Trailer has the best prices, great customer service, and order to delivery was 4 days, cant beat that. 110027

Product information for my vehicle was excellent! I live clear across the county from the warehouse I ordered from, It took 7days from order to home delivery. When the product arrived It was easy to install, the instructions with the product were very clear. It sure is nice when a company delivers what you order, in a timely manner and the product does what it is suppose to do. Thanks for the great experience! 121923

Ordered this item from Bill E. questions were fully answered and product was shipped and received promptly. Price was outstanding, easily several hundred dollars less expensive than RV dealer. All items in box accounted for making for a painless installation. I am completely satisfied with this transaction from etrailer and I am going to order additional merchandise soon. Thanks for a great deal. Thomas 122121

I could not be more happy with my weight distribution system w/ sway control.To start with just placing my order was a breeze. They let me know right off my order had been recieved. The same day my order was shipped. Kept up with on line shipping where my order was at and when to expect my order. It was delivered right on time.And in no time I had it put togeather and ready to use.Thank You. 135763
Product arrived timely and as expected. Instructions were very clear, as well as videos found on eTrailer's website. The installation went flawlessly and works perfectly on my truck and trailer. The only issue I ran into was not having a "cheater" bar to adjust the chains into the right position. That will be easily resolved by buying a short piece of pipe at the hardware store. 46613
by: Brian B.07/30/2013
Simple ordering process on-line, shipped and arrived within 5 days High quality steel, easy to assemble and simple to use. Overall great product, I would recommend this product. 92319
Received order in a very prompt manner, (regardless of the weather problems on your end). Installation went as instructed with all parts included. Test drive was uneventful and could feel the improvement from the cab of truck..Looking forward to vacation time and not having to fight the sway caused by the big trucks on the freeway and the heavy tongue weight. 68373
I ordered a new hitch for hauling my camper Iwanted this product because of the weight distribution system it makes for safer hauling the product arrived one day after I ordered it I put it togther and can't wait to use it thank you etrailer 64376

This was exactly what we needed. Everything in 1 complete package. Quick & easy to install, and use. Communication from etrailer.com was very impressive.

Very impressed with this company, and will do business with them again. 48412

The Wt distribution system was complete and very easy to assemble and I hooked up quickly to the camping trailer and went for a test drive. The whole system worked perfectly.

Thanks guys guys your all GREAT!!!!!!! Thanks again for Everything! 122693
by: Carolyn & Marvin S.09/24/2013
Great Product!! We are very impressed with the quality. The Pro Series Weight Distribution w/ friction sway control was much better than expected. Father and son installed it in one afternoon. We will be using it on our car hauler trailer to keep the handling to a minimum. We are extremely pleased with the product. 101204
by: Cheryl Sovern04/15/2014
This is the first time I have towed a large trailer with my truck. I purchased this product with the hopes it would make towing feel like there was nothing behind my truck, I was not disappointed! I would recommend this product to anyone who has to tow a travel trailer behind their vehicle, it was also a great price. 125139
by: Larry H.07/28/2013
Product was very easy to install . But, I wish the customer service rep would have asked what size Ball my trailer was out fitted with . So I had to go to your web site and buy the correct ball . If and when I need more product for towing I will be back to your site . Your prices were with in my budget . Thanks again 91995
this was exactly what I was looking for ,it works like it was made for it (my new 24' traveltrailer). The ease of ordering ,the cost,and the speed of delivery was worth it! I wouldn't hesitate from ordering from etrailer.com again. Thanks 73922

Great product. easy to install and use. fit perfect, I tow an 18foot trailer with a 2013 4runner and this hitch gets rid of the "4runner sag", just wish I could use it on my boat trailer with surge brakes. shipping was fast and contact with etrailers was great with email. 116089
by: Kerry W11/01/2012
Product was delivered VERY quickly. It was easy to install. I only had to adjust it once, but did it before everything was tightened up. My trailer pulls a lot better with very little dip and sway. Product is very well made. I will definately buy from etrailer again. 58560
by: MICHAEL T.02/28/2014
Great product.. super fast service. I will be traveling cross country towing my travel trailer. I may not need the extra control, but I would rather have it and not need it, than need it and not have it. Easy installation, clear instruction. Thanks etrailer. 118005
by: Kenneth E.06/26/2013
product is extremely well built and sturdy. Installation was fairly easy, but I got most of my installation info from the video on the website. I would recommend this product to anyone who is looking for a quality weight distribution hitch at a great price 86249
This product arrived in about 5 days. Very quick shipping for standard shipping method. I set this hitch up on a 23' camper to pull behind a 2002 S10. Wow this thing is amazing, very affordable, great quality, and it made a huge difference in the towing. 74621
The hitch kit, I ordered, was easy to install and very well built. I would recommend trailer hitches and parts from etrailer.com to anybody. The shipping was a little high but I did get the order in two business days, so I can't complain too much. 65437

Five stars for this Pro Series Weight Distribution System w Friction Sway Control. If there were 6 or 7 stars, I would give it that. Very easy installation. Installed in about 1 hour. Very reasonable price for a quality product. 92417
Very nice product and a great price. Good thing eTrailer had a video to supplement the product installation instructions as the instructions left me with many questions. Still have questions about the adjustment for the sway bar. 80879
SUPER PLEASED WITHTHE HITCH AND ESPECIALLY THE FAST DELIVERY. YOU ADVISED MONDAY PM THE HITCH WAS SHIPPED, THURSDAY AT 3PM IT WAS IN MY GARAGE HERE IN FL.. THE HITCH SEEMS TO BE OF GOOD QUAILTY AND SIMPLE TO ASSEMBLE AND SET UP 76805
by: Tim Atkinson06/13/2014
Very happy with the hitch and bars. The video on installation was better than the instructions. The only thing I noticed is there is nothing stating how tight to make the sway control. I guess it a trial and error setting. 135451
by: cliff k.07/25/2013
