When crosswinds, passing trucks, or uneven pavement try to push your trailer around, the Blue Ox SwayPro keeps it steady and in line. The hitch head has a built-in positive caster angle that works like your vehicle’s steering alignment to help the trailer self-center. Constant tension in the trunnion bars adds another layer of stability, keeping your trailer directly behind you without the jerking or fighting that comes from standard setups. The tighter chain design at the lift brackets limits bar movement so everything stays quiet and smooth, even when the road doesn’t.
No one likes the creaks and pops that come from friction-style sway systems. The SwayPro avoids that by using rotating clamp-on brackets that hold the chains tight and stable. Only a couple of links hang free, which keeps the spring bars steady and eliminates the grinding and clanking of metal-on-metal setups. The result is a silent, confident ride that feels like the truck and trailer are one single unit.
Getting this system ready is quick. The hitch head comes with the correct angle preset, so you don’t have to mess with washers or hard-to-reach bolts. Just bolt the head to the included adjustable shank, slide in the trunnion bars, and secure them with the provided clips. To tension the lift brackets, drop the chain into the slot and rotate with the included wrench until the lock pin clicks in. No heavy lifting or snapping bars into place—just a clean, quick setup that most folks finish in well under two hours.
Trailers with bottom-mounted couplers need the right hitch head geometry, and that’s exactly what the SwayPro BXW0553 provides. It’s built for underslung designs and maintains proper ball angle to keep your trailer level. The unit fits 2" x 2" receivers rated for weight distribution and handles 350 lbs to 550 lbs tongue weight with a 5,500 lbs gross towing weight. The durable, powder-coated steel construction resists corrosion, and the integrated grease zerks make maintenance simple and clean.
The SwayPro evenly distributes tongue weight across all your axles, preventing sag and restoring control. Your headlights stay level, your steering remains responsive, and your trailer tracks straight behind. With its 2-5/16" hitch ball, 8" maximum rise, and 2" drop adjustment built into the 13" shank, you can fine-tune height for a perfectly balanced rig. Everything you need—head assembly, spring bars, lift chains, brackets, and hardware—is in the box, ready to go.
Ratings & Reviews
Haven't opened the product yet, but etrailer's service was phenomenal. It took less than 5 minutes to order the product, and within an hour of the purchase I got an email saying the hitch had shipped. I was expecting a delay with the current events taking place, but I was shocked to have the hitch on my porch the very next day.
Very well made easy installation seems to work well on short test drive will know more when I travel the Interstate highway
Everything went great with the installation. Looked at etrailer's video on line and that really helped. etrailer kept me informed on the shipping. Very happy with everything.
Have been using this hitch for one year now. We have had zero issues, it is easy to use. Satisfied!
Easy to use and provides the best weight distribution and sway control.
Significantly better than the one the RV dealer sold us with the camper. 2000# hitch handles the 39 foot toyhauler flawlessly. Lots of adjustment ability with it.
The product is great but the customer service needs to be dealt with. I ordered what I thought was the right sway controll bar and they sent me the wrong one to start with, then I ordered the right one and they sent it to me, but I have yet to recieve my credit on my card. They told me a week ago that it was already back to you and I don't understand why we have not recieved our credit on our card yet.

I have 2 trailers and had this on a 34 foot travel trailer that weighs 9200 fully loaded. The weight distribution and sway control was subpar at best. My husky centerline rode better and controlled sway and weight distribution. Had to put this on the smaller of our travel trailers because it didn't do the job.
Works well. Upgraded from Equal-i-zer 1k/10k due to hitch weight. Sway control seems to be about equal and hitching & unhitching is much easier due to lower jacking height required. Hitch adjustment is MUCH easier.
The SwayPro bars are aptly named. My first trip with these bars was through the windy Columbia River Gorge. There was a marked improvement over the load distribution hitch I used previously.
The SwayPro was easy to install (but a good torque wrench is needed). Once installed, hookup was also big improvement over a standard load distribution hitch.
I have been very happy with the performance of this hitch. Our first time out I was on a cross wind that was very harsh and was worried with my 36'.
Unlike other trailers on the road, I was not fishtailing. I was still fighting the wind, but was not all over the road had I used a different setup.
My only issue is the difficulty of getting the chains on and off without them popping.
Other than that, I highly recommend for stability!!!
I love the Blue OX. Much easier to use and maintain than the Equalizer, which is what I had previously. I think the BO is equal in effectiveness at sway control to the EQ but not sure because I'm now pulling a bigger trailer. The cam latch system with the BO is easy to use but you must raise the trailer tongue "to the sky" in order to release the tension from the load bars before releasing the chains. The load bars will slam down if you're not careful creating a hazard if you're not careful.
etrailer is excellent as far as providing vast amounts of info before the sale and providing communication after placing your order through order delivery, and even after delivery. What other company shows you when and who processed your order, who packed your order, who shipped your order - providing names and pictures of the people involved along the way, along with all the other tracking info.
As far as the equalizer hitch, I haven't towed with it yet but seems extremely heavy duty and well made and should do the job. Most reviews I researched on it were good. I will follow-up once I tow with it.
I do have a few issues with it though before even using it.
First issue is that the spring for the spring loaded button that holds each equalizer bar into each side of the head is so strong that it can't be lifted up with fingers in order to release the equalizer bar when removing them. Need to remember to have a screwdriver handy to pry the button up in order to release the bars. I did see 2 versions of equalizer bars in videos. One version had a slot, one version had a blind hole that these buttons went into. The bars having the slot allowed the bars to be rotated during disassembly for easy removal. Can't do that with the blind hole version. I don't know which version is the latest or best - I will call etrailer or Blue-Ox to find out. I had 3 people try to lift up on the buttons with the hitch assembled but not installed, and no one could lift them enough to release them. That might be a good thing though - prevents them from inadvertently releasing.
Also, based on the 2 sets of exploded views that came with the instructions (one dated 2013, one dated 2020), it appears I might have received an older model that comes with a flat rotating latch wrench because the newer dated exploded view shows a rounded wrench (like a lug nut wrench) with a different p/n. I'll have to call etrailer or Blue Ox on this issue too.
Lastly, the box the hitch came in was heavy duty, but it still should have been a little stronger knowing how very heavy packages get handled by delivery services. The box had a small opening ripped open in it in the corner and the hand hold slots were ripped open twice as big as normal, along with the hardware bag inside was ripped open. Some hardware was scattered inside the box when I opened it and 2 of the 4 hex headed "set screws" were missing. Although you only need 2 set screws, these were different lengths, so I contacted etrailer and they have been working on getting me replacements.
Lastly, I can now see after watching some of the review videos on You Tube and playing with the hitch - about what some people were talking about - how the chains could get wedged during use unless you twist them somewhat, and I can also see how when you try to do a controlled release of the tension on the equalizer bars with the rotating latch wrench - if you don't have a lot of the pressure off of them by jacking the hitch up high enough before releasing them that this may cause the wrench to uncontrollably rotate into the released position unless you really have a good hold on it - which may be hard to do since you're other hand would be busy removing the release pin on the rotating latch. I'll know more when I actually use it, but it has me a little concerned.
I have no experience with other WDH's but this unit does what I expect it to do. I pull a 33' 7,500# Jayco trailer and it allows me to move the weight as needed to the front axle and it seems to control sway very well. I originally used this with an F-150 that was exceeding my rear axle rating so it was crucial that I get the weight shifted forward which this unit did well. I have since moved up to an F-250 so it is not nearly as critical but it still makes the trips pleasant. This unit is specific to underslung couplers like Jayco uses. Also being able to back the trailer without disengaging the WDH is an advantage over some of the other brands. The action of the chains during disconnect can be intimidating and dangerous until you get accustomed to the process. The one complaint I have is not with the unit itself but the wrench that is provided to load and unload the chains. It is flat (hurts your hand) and too short to get adequate leverage. I suggest you use an 18-24" cheater bar with a 1" socket to load/unload the chains. Otherwise very happy with the purchase
I have had the Blue Ox BXW1003 for a year now and overall we are pretty happy with it. With our previous camper (Dutchmen) we were using a Draw-Tite WD hitch with a separate friction sway control bar. When we bought our new Jayco camper, we had a different A Frame design (underslug coupler) and it is a much bigger camper so we needed to upgrade the hitch. We liked chain style connection of the Draw-Tite but didn't like having to get out and remove the friction sway control bar when backing into a site. With the Blue Ox we just pull up to the site, someone hops out to guide clear the site as we back right in. It is nice to have a chain setup because there are times where I need more spring assist than others. For instance, we dry camp from time to time and have an A Frame Shelf above the propane tanks for our generator. The dealer recommended the Blue Ox over the equalizer because of this changing load requirement and it has worked.
The only reasons I am not giving it 5 stars is because there are times where I have to fight with the release pin a bit. You have to turn the cam a bit to get it to release. It isn't a big deal and doesn't happen all the time but enough to stick in the back of my mind. The tool for turning the cam is a bit short and because of the A Frame shelf I have to be careful about where I put it on or as I turn the cam, it could pinch my hand up against the shelf mount. Like many people, I just got a big socket and breaker bar to replace the included tool. In my case I already had the breaker bar for torquing the wheels so I just needed a socket. Because the socket pivots it can't pinch your hand and is longer so more leverage. Also a drawback is because of the design, if we were get a new trailer that maybe doesn't use an underslung coupler, but the same weight as our current camper, we would have to buy a new hitch as well. This is because there are different models based on hitch type, where an Equalizer can be adjusted to accommodate either coupler style, the Blue Ox can't. Sure you could probably replace the parts needed to convert it or just buy a new one. This is a minor thing in my book and the nice part about this is that it makes it much easier to set up at home since there are not as many points of adjustment. If we didn't change our load frequently depending on where we are going and traded in campers every other year, then we would have been better off going with the Equalizer. For us the Blue Ox was the better fit.
I will say that before buying I contacted Blue Ox's Customer Support as I had a question. I wanted to make sure I had the right model to work with the coupler on our camper. I was 80% sure I was right but didn't want to get there to pick it up and find out it wasn't the right one. Not only did they clear that up but the rep reached out to engineering and asked about my tow vehicle so they could verify that the included drop hitch was the right one. Which wasn't even a question that I had.
Looks well built and well thought out. If you ever switch to a heavier trailer you can just purchase new bars and keep the rest. I researched videos on YouTube and there was one negative review, blue ox made corrections and resolved those minor issues with the wrench slipping. I’m using this for an 18,000 lb stacker trailer and it is the only hitch I could find rated for the heavier trailers.
Even though I ordered the wrong thing (absolutely my fault), everyone was super nice and helpfull. The parts even arrived a day ahead of time. I will absolutely order from etrailer again when I need to.
I bought a weight distribution hitch w|sway control, and a trailer brake controller for my Four Winds RV. I received my order today, within a few days of placing the order. I have not installed it yet but it appears to be user friendly. Both pieces are made by Curt so the quality & performance should be good.
My thanks to etrailer & Stacy??
Great product, easy to install. Fast d elivery.
Very happy with the ease of install and the performance of the hitch
You need to get a little better on the pins holes that connect the bars to to equalizing head. On the under slung I bought the bar pin holes did not line up with the pin holes on the head. I had to drill it out to get the bar retaining pin to go through. Otherwise it was all good.
Very easy to do business with! Shipping was fast and on time.
performs to every standard that I required. Pulls my trailer effortlessly.
Very pleased with their product and ease of installation and hook up. Good instructions on proper preload. Towing a 15k stacker with a 2011 F350 single rear wheel. Good sway control
This item was shipped direct from the manufacturer. It was received in a timely manner. It was eligible for free shipping but I opted to pay for expedited shipping, and it came as promised, well packaged.
