Crosswinds and sudden gusts can make a trailer wander, but the Blue Ox SwayPro Weight Distribution w/ Sway Control (5,500 lbs GTW, 350–550 lbs TW) keeps everything steady. The hitch head has a built-in positive caster angle that creates a self-centering effect, working with the trunnion bars to hold the trailer directly behind the tow vehicle. Constant tension in the bars helps correct sway before you even feel it. The result is a smooth, quiet tow without the grating noise common in friction-style hitches.
Uneven load transfer can make steering light and cause the rear end to sag. This system evenly spreads tongue weight across all axles of your tow vehicle and trailer so both stay level. With a 5,500-lb gross towing weight and a 2-5/16" ball, the setup lets you tow at full hitch capacity while keeping the trailer stable and level. Your lights, tires, and handling all stay where they should be—balanced.
Unlike snap-up bar systems that pop and creak, the SwayPro’s rotating lift brackets keep the chains tight and the bars stable without noise. Only a few chain links hang down, which limits movement and adds more control. You can also back up without disconnecting anything, so it’s easy to maneuver into a campsite or driveway.
The hitch head arrives with the correct angle preset, so it’s ready to use right out of the box. Just adjust the head height on the 13" shank, insert the trunnion bars, and secure them with the included pins and clips. Clamp-on brackets need no drilling, and built-in grease zerks keep maintenance clean and effortless. The durable powder-coated steel finish resists corrosion for long-term dependability.
If you upgrade trailers or your tongue weight changes, you don’t need a whole new hitch. The SwayPro head accepts a range of replacement spring bars rated from 350 lbs up to 2,000 lbs TW, so you can match your setup exactly. It’s a flexible system that grows with your towing needs.

Haven't installed it yet, but it's built like a tank...
Received product in good time.
The camper is very stable on the road.
Very well built and relatively easy to install.
I chose this product as I was able to install it myself which saved about $300-400. Connecting and disconnecting is easy. Overall a good purchase.
The Blue Ox trailer hitch works great.
Instructions could use more detail. Had to watch a few YOUTUBE VIDEOS.
Overall it serves its purpose, however, we were disappointed with the corrosion and flaking of the powder coating. The powder coating bubbles and flakes where the load/sway bars flex.
excellent product and better customer service. good videos on how to install. Hitch ball came installed and made it easy for assembly.
I put this on my trailer as soon as I bought it (Coachman Apex Nano 194BHS) so I can't say how it would drive without it. But it is a very solid and well crafted system. No weird popping noises from it, which is what I didn't like about solid bar systems. Installed quickly and easily (watch the etrailer install video!)
Mine came with the new hefty tire iron like wrench (instead of the flat knuckle buster). Seems like a huge improvement, absolutely a necessary upgrade for such a premium product
Outstanding service! I ordered several components from etrailer late afternoon and I received them the next day. Everything was well packaged and nothing was missing. I was also told to call if I had any questions. We'll use them again.
This weight distribution system is the best. It is easy to install and if you need to put it on a different trailer that has a different weight you just have to buy new distribution bars.

This system works great. Needs to have a better system to lock in the parts that go on your trailer rails. Sometime they come loose.
Easy installation after purchasing a couple of specific tools: A big adjustable wrench, a Torque wrench and a 1 1/2 socket to be able to remove and reinstall the hitch ball.
Easy to follow instructions.
Plan to test it during a trip this weekend.

Highly recommended for any travel trailer. Absolutely necessary for safety. Easy to setup and remove. You can backup without removing it.
The BEST Purchase I've made thus far!! Once I installed the new hitch system I can honestly say it made a 100% difference! I have a Mercedes ML500 and I pull a 17' Forest River Wildwood X-lite travel trailer. There is no more sag in the middle, both tow vehicle and trailer are level driving down the road and my SUV handles almost as if there is no trailer on the back! I HIGHLY Reccomend the "Blue Ox" System! It's the best!

Still The BEST Purchase Ive made thus far for my trailer! Now that I have used it multiple times, I can say its a life saver in so many ways. My tow vehicle is stable on the road, breaking, maneuvering, the weight distribution has been key for me with a smaller set up and the Blue Ox continues to deliver. I Still HIGHLY Recommend the Blue Ox System to everyone!!
We have a 24' travel trailer pulled by a Suburban. This hitch levels everything out and makes handling much easier. Very little sway, only during windy storms and the suburban is much easier to drive. This hitch is also easy to set up (we were lucky to have a local store install it) and very well built. Etrailer delivered it fast, no damage and had the best price by far.

Great hitch. Weve taken 3 trips to other states and have even had a tire blow out and this hitch is so good, I almost forget the trailer is there.
Have used the SwayPro for 1 year now and overall very satisfied. I tow a 23' Airstream which weighs about 5500 lbs. The receiver hitch mount that comes with the SwayPro was unable to get the ball low enough as instructed in the Install Instructions so I gave Blue Ox a call and they immediately shipped out the one I needed and I shipped them the original. The BO SwayPro is fairly easy to operated and is quiet. I will say that it does not eliminate sway, I have tried several different adjustments but anytime I drive above 65mph, especially in headwinds or gusty conditions, sway is possible. The sway is manageable by slowing and never gets too bad but it will make you grip the steering wheel tighter. I was not surprised by this, just had a hard time shelling out the $2500 needed for the non-swaying hitches.

The Blue Ox is performing fine, it does not eliminate sway but as long as I drive 65 mph or less, sway is rarely an issue. As you go over 65 sway can happen with adverse winds, semis passing, or poor road conditions. One other nuisance, is when I attempt to disconnect the chain on the right side, the chain sometimes gets wedged in the metal channel that you rotate and will not release. Usually I have to spray the area with a lubricant and then rotate the whole “chain engaging device” back and forth and the chain will become unstuck so that I can get the bar off. All else is fine, sometimes I do wish I had bought the Pro Pride but that seems a bit too complicated, heavy and expensive.
So much help
Have not used it yet, it is heavy duty!
We used it a lot last year towing with our Highlander but have switched to our Tacoma to tow now. We still use the Blue Ox system for the sway protection. At times I forget I am towing!
After much research, I chose this Blue Ox. Liked this style over the others for it's simple use and less clips to lose. My issue was the rear of my KIA was sagging allowing the camper nose to drop. Which in turn made the camper sway. Very simple installation. The object is tweaking it to get both the tow vehicle and camper level and to line the chain up with the bracket mounted on the frame of the trailer/camper. We've taken it out on 1 short trip so far and it has definitely been an improvement. It is quite heavy, but just about all brands are. Read others that said the ball was not included..... mine was! Very pleased with my decision.

This is a wonderful product. We pulled a 25 travel trailer on a long trip last year and I didnt have to worry about any sway on any road. The Blue Ox handles cross winds easy also. Very easy to use, I wouldnt buy anything else!
