If you're looking for an American-made hitch that rides quietly, offers a quick and easy setup, and provides you with supreme handling, the Blue Ox SwayPro might be just what you're after. When we tested this system, the truck and trailer felt like one unit, and noise wasn't an issue at all. Overall, the SwayPro came out on top and proved to be one of our favorite weight distribution systems.


Pro Tip: Before you invest in a weight distribution hitch, make sure your cargo is evenly loaded in your trailer to keep the weight balanced. If you still have a hard time even after balancing your tongue weight, a weight distribution hitch should help.


Blue Ox SwayPro Offers Superior Sway Control

Blue Ox SwayPro Positive Caster

The SwayPro is designed to keep your trailer centered behind your vehicle as you tow, no matter what crosswinds or obstacles try to get in your way. To do this, the head on the system is built with a positive caster angle. You might've heard of caster in reference to your car; it's the same technology that vehicles use to stay centered on the road. When you turn a corner in your car and let go of the steering wheel, the wheel automatically returns to center. This is caster taking over. Well, the SwayPro functions much the same way. The positive caster angle that's built into this hitch works in tandem with the tapered spring bars to create a self-centering force that keeps your trailer consistently centered behind your tow vehicle.


Blue Ox SwayPro System with Built-In Sway Control Hooked Up

The trunnions inside the head assembly hold the spring bars securely in position, placing just enough tension on them to cause them to constantly hold your trailer in line.



A close-up shot of the Blue Ox SwayPro's bracket shows the chain rotated and pulled taught with very few chain links exposed

At the other end of this weight distribution system, you'll find 2 more points of built-in sway control. Blue Ox's rotating brackets ensure that the lift chains are pulled as taut as possible, with the majority of the chains wrapped up inside of the brackets. Typically, only a couple of links hang down from each bracket. This means that each chain is held more stable than they are in traditional weight distribution systems, where more than twice as many links are exposed.


This tight, stable design limits the movement of the spring bars so that they can exert more force on your trailer to effectively keep it from swaying - all without the creaking, grinding, and popping noises you get with friction-style sway control setups. Moreover, unlike many friction-style sway controls, the SwayPro allows you to back up your trailer without having to remove or disengage anything.


The Blue Ox SwayPro's No-Hassle Setup

When it's time to install the system for the first time, you might be surprised at how easy it is to do. All in all, you can probably have it done within an hour - 2 at the most.


First, the head. With just the right amount of adjustment angle already preset, it's ready to go right out of the box! No need to fine-tune it with hard-to-access washers or a difficult-to-use thumbscrew! The only thing you'll need to adjust is the height of the head on the shank. After that, to get the trunnion bars installed, just insert them into the sockets, and lock them in place with the included pins and clips.


Quick Tip: If you upgrade to a new trailer in the future, and you end up needing a system for a different tongue weight, you can just swap out the SwayPro's spring bars without having to buy a whole new hitch.


To get the Blue Ox SwayPro ready to go, just insert the lift chain into the bracket slot and rotate the bracket with the included wrench until the lock pin engages.

Other weight distribution systems have lift brackets that require you to apply a good amount of leverage to get them to snap up, which can be difficult and frustrating. To get the SwayPro ready to go, all you have to do is insert the lift chain into the bracket slot and rotate the bracket with the included wrench until the lock pin engages.


Why Use a Weight Distribution Hitch?

Diagram showing weight distribution on a truck and towing a camper

  • Prevents uneven tire wear on your vehicle and trailer
  • Keeps the rear of your tow vehicle from sagging
  • Lets you tow to the max capacity of your trailer hitch
  • Stops your headlights from pointing up at the sky
  • Gives you control over steering your rig

Selecting the Right Weight Distribution System

  • Think "Goldilocks"
    • If you go for overbuilt, you'll have a rigid ride
    • If it's not strong enough, it's virtually useless
  • Let your tongue weight be your guide

Your tongue weight is the first thing you need to know when figuring out which weight distribution system you need. Most people think that if they get the highest-rated system possible, it'll be smooth sailing. But actually, this will create a rigid ride and a bouncing trailer. On the other hand, if the system isn't strong enough, it won't be able to distribute the weight properly, making it virtually useless.


Once you know your trailer's tongue weight, add it to the weight of the cargo behind the rear axle of your tow vehicle. Then just choose a weight distribution system rated for that combined tongue weight.

  • Determining Which Blue Ox SwayPro Hitch For Towing Airsteam Bambi W/ 2019 Honda Ridgeline
    I would be happy to help you find the correct Blue Ox SwayPro weight distribution hitch for towing your Airstream Bambi with your 2019 Honda Ridgeline, but you will need to confirm your total tongue weight. Total tongue weight is the tongue weight of your fully loaded and ready to tow trailer plus the weight of any cargo behind the rear axle of your Ridgeline. The easiest way to get an accurate tongue weight measurement is using a tongue weight scale like the # e99044 but there are other...

  • Adding Weight Distribution and Sway to a Straight Frame Boat Trailer
    For your Magic Tilt Boat Trailer you will need a Blue Ox Pole Tongue Weight Distributing Hitch Adapter # BXW4023. This will bolt around the Pole frame with a width of 2-3/4" to 4-1/2" and height of 3" to 6". It will then allow you to use a weight distribution hitch that utilizes over frame brackets. I recommend the Blue Ox SwayPro Weight Distribution w/ Sway Control # BXW0556. This system will allow you to back up your boat trailer without removal and will not interfere with the surge...

  • Recommended Weight Distribution Hitch for 2021 Lance 1995 with 390-lbs Dry Tongue Weight
    You will want to choose the correct system based off of the loaded tongue weight of your trailer; this should typically be between 10% and 15% of the loaded weight of the trailer. I recommend using the Equal-i-zer Weight Distribution w/ 4-Point Sway Control - No Shank - 6,000 lbs GTW, 600 lbs TW # EQ37061ET which is designed for trailers with up to 600-lbs of tongue weight. I prefer the Equal-i-zer since it's going to provide 4-point sway control, as opposed to the Fastway # FA92-00-0800...

  • Upgrading Blue Ox SwayPro From 550 lbs Tongue Weight to 750 lbs Tongue Weight
    The Blue Ox SwayPro Weight Distribution # BXW0556 you have is designed for total tongue weights from 350 lbs to 550 lbs, so it won't be effective for you. It will essentially be like you don't have a system on because it is not rated high enough for your tongue weight. So you will either need a higher rated hitch, or you can just replace the spring bars with the higher-rated option. For that you will simply need the Replacement Spring Bars for Blue Ox SwayPro Weight Distribution System...

  • Do I Need a Weight Distribution Hitch for a 3500 lbs Trailer and a 2017 Toyota Sienna?
    Thanks for the pictures! It sounds like you would benefit from having a weight distribution system and all of your components are compatible with one. I recommend the Blue Ox SwayPro Weight Distribution item # BXW0556. This is a clamp on system that requires no drilling into your trailer's frame to attach the hanger brackets. The built in sway control will keep your trailer in line with your 2017 Toyota Sienna when you're driving down the highway and get passed by a semi. It has a 6,000...

  • Recommended WD System for Towing a 4,300 lb Jayco Trailer with a 2012 Nissan Frontier
    When looking at a Weight Distribution (WD) system you will want to choose one with a Tongue Weight (TW) range that the Total Tongue Weight (TTW) of your towing setup falls in the middle of. To find the TTW of your towing setup you will need to add the TW of your fully loaded and ready-to-go trailer along with the weight of any cargo behind the rear axle of your 2012 Nissan Frontier. Keep in mind that a properly loaded trailer will have a TW that is 10-15% of the loaded weight of your trailer. If...

  • Width of Blue Ox BXW0556 SwayPro Weight Distribution System Chain Hanger Brackets
    According to Blue Ox, in order to achieve the proper weight distribution performance, the chain hanger bracket would need to be installed no more than 1 inch fore or aft of plumb. The portion of the frame bracket that passes over the top of the frame member measures 4 inches in width. At its widest point, the portion of the bracket that abuts the side of the frame member is 5-3/4 inches. Blue Ox does offer a separately-available under-mount lift bracket as part # BXW4020.

  • Recommended Weight Distribution Hitch For A 2018 Jayco Jay Feather 19UHD Travel Trailer
    Out of all the weight distribution hitches we offer I personally prefer the Blue Ox SwayPro because it's the easiest to install and use. With your tongue weight being less than 10% of your GVWR you could definitely benefit from loading more in the front of the trailer to increase the tongue weight. Once you have that tongue weight up a little more I recommend going with the Blue Ox SwayPro Weight Distribution w/ Sway Control # BXW0556. I've attached a picture below with the dimensions...

Other than that, the two systems are identical according to my contact at Blue Ox. We carry that shank # BXW4000 but not with a system. If you need more drop for your Tacoma, we do have the 11 hole shank in the Blue Ox SwayPro Weight Distribution w/ Sway Control # BXW0556 which other than the shank is also the same system. With...

    I can help you find a Weight Distribution (WD) system that works for you, but since it looks like you will have a pretty big range of weight capacities it is impossible to use the same WD system without changing out at least the arms. You will want to choose a WD system with a Tongue Weight (TW) range that the Total Tongue Weight (TTW) of your towing setup falls in the middle of.

  • Recommended Weight Distribution System for Towing an R-Pod 172
    Since you will be adding the 100 lbs behind the rear axle of your 2002 Ford Expedition it really boils down to how much tongue weight your R-Pod 172 will have when it is fully loaded. If you are at the lower end then the Blue Ox SwayPro # BXW0556 with the max tongue weight of 550 lbs is the weight distribution (WD) system you want to go with. If your loaded tongue weight is on the higher end the SwayPro # BXW0756 with the minimum tongue weight of 550 lbs is the better option. For something...

  • Which Blue Ox Weight Distribution Hitch & Additional Arms For 3,500 lb to 6,500 lb Trailers
    Hey Edward, It does make sense and a single Blue Ox weight distribution hitch isn't going to cut it, as it won't be effective with all those weights. For trailers between 3,500 lbs to 6,500 lbs you're looking at total tongue weights ranging from about 450 lbs to 850 lbs (depending on how the trailers are loaded). So what you'll need is a Blue Ox system and three different arms: - Blue Ox SwayPro Weight Distribution w/ Sway Control - 5,500 lbs GTW, 550 lbs TW # BXW0556 - Replacement Spring...

You'll have to get the right SwayPro and use the brackets as replacements for the ones that come with the system.

    I can certainly point you in the right direction. According to the online owners manual, a Rockwood A214HW has hitch weight of 353 lbs. Looking at pictures of these campers, it certainly looks like there is limited space on the tongue. In that case we have a few options. First we could go with the Fastway e2 # FA92-00-0600. The frame brackets on this system need to be placed between 27"-30" back from the hitch ball. This is their 6,000 lb system, and will work on trailers with a tongue...

  • What Does Tongue Weight Rating of Weight Distribution System Mean
    Hey Jean-Guy, so the Blue Ox Weight Distribution system part # BXW0556 that you have was designed to work on trailers that have a tongue weight range of up to 550 lbs. It doesn't actually have up to 550 lbs of support it can be adjusted to. You wouldn't want to attempt to adjust it up to a certain rating and instead you'd want to follow the instructions to provide the spring bar tension to allow the trailer to be towed as safely as possible.

  • Recommended Trailer Hitch and Weight Distribution System for Hauling With a 2004 Toyota Highlander
    You are right; when considering the Tongue Weight of a trailer hitch, we only count the Tongue Weight of the trailer. Tongue Weight, when looking at Weight Distribution Systems, is determined by the tongue weight of the trailer plus any cargo that will be sitting behind the rear axle of the tow vehicle. In the case of your 2004 Toyota Highlander, I looked up your owner's manual and it looks like your total load capacity is 860 lbs without the third seat, and 1159 lbs with the third seat....

As long as your total tongue weight is under 550 lbs, the Blue Ox SwayPro Weight Distribution w/ Sway Control - Clamp On - 6,000 lbs GTW, 550 lbs TW # BXW0556 will work well.
