Create a more 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 of 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, and it also gives you the ability to tow the maximum capacity of your hitch.


Blue Ox weight distribution system

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 towing 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 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.


2 Types of Sway Control

The TrackPro features 2 different sway control technologies to provide the best towing experience possible.


Positive Caster Keeps Trailer Centered

Blue Ox TrackPro Positive Caster

The TrackPro is built with a positive caster angle - pointed toward the rear of your trailer - to help stop sway before it even starts. This is 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 corrects itself and returns to center. This is caster taking over. Likewise, the TrackPro features a positive caster angle built into the hitch. Working in tandem with the tapered spring bars to create a self-centering force, this caster angle helps to keep your trailer consistently centered behind your tow vehicle, even during high winds and sharp turns, resulting in a smoother towing experience.


Steel-on-Steel Friction Corrects Sway

Blue Ox TrackPro Steel-on-Steel Friction

While this system does its best to keep your trailer in line, the TrackPro is also able to correct sway should it occur. Unlike many traditional weight distribution systems with chain-style setups, the TrackPro uses steel brackets to hold the ends of the spring bars, and therefore your trailer, in place. While chain-style setups do a good job with weight distribution alone, they aren't really designed to limit sway, so they typically allow a good amount of side-to-side play.


In addition to better holding the trailer in line, these brackets create friction with the spring bars to combat sway that might occur in heavy winds or following sudden maneuvers. When this type of sway happens, the tapered ends of the spring bars slide within the L-brackets that are mounted on the trailer tongue. When each spring bar moves forward or backward, or side to side, it rubs along the bracket, creating friction. This friction limits the movement of the spring bar, which minimizes further side-to-side movement of the trailer. The steel-on-steel friction that occurs with the TrackPro's spring bars is the same sort of friction that is used with locomotives that pull loaded railcars that weigh multiple tons, so you know it'll be highly effective.


Fast, Easy Setup

Blue Ox TrackPro Hitch Head

Many weight distribution systems require you to manually adjust the pitch of the hitch head by stacking washers. This can be a tedious, trial-and-error process where you have to unhook your trailer, disassemble the head to add or remove washers to get the desired tilt, put it all back together, and then determine if you have the correct placement. If the pitch still isn't right, you have to do it all over again.


The TrackPro removes all of that hassle with an easy-to-use hitch head that has the required pitch already built into it. Whereas other systems require washers to help achieve the proper tension in the head, the positive caster angle built into the TrackPro ensures the proper pitch, so there's no need to manually adjust the tilt. The only adjustment that may be needed is the placement of the head on the shank. Move the head up or down along the weight distribution shank to achieve the proper rise or drop for your setup. No additional, fine-tune adjustment is needed.

This thing is amazing! I bought this to haul my 24’ car (toy) hauler behind my 03 Suburban which has coil springs instead of leaf springs. This hitch has made a world of difference. I honestly was shocked at the difference it made. It almost feels like I’m not hauling a trailer at all.



by:

Weight distribution system is just like any other ones I have used, (chains, etc.), paint wears off quckly on the bars and hitch. L Pins undersized and had to purchase larger pins from e-trailer since the original ones which came with the hitch were undersized.

Easy to install, simple to use and distribution/sway reduction is noticeable.



by:

It was installed professionally by camping world. Coating is all coming off. Arms pop out during travel. The square pins fall though slots. The angled brackets that mount to camper chassis are failing. Its the worst hitch I have ever owned. Literally.



by:

I like the hitch and it works great with my '07 Tundra and 27' Travel Trailer. It makes the two feel like you're driving a single vehicle and Cross winds and buffeting from passing semi's is virtually unnoticeable. Unfortunately, the Powder coating leaves a bit to be desired and warrants a significant mark down in the rating.

Pros: Easy of installation and hooking up the hitch. Adjustments are also very simple.

Cons: The "Powder Coating" is atrocious. It showed up flaking out of the box and just continued flaking during the installation. So, it started immediately surface rusting. I didn't think it worth returning and I guess I will just touch it up with spray paint as needed. Powder coating should be significantly tougher than what I see on this hitch. If it wasn't for this I would absolutely give it 5 stars. In the picture with the 2 bolts is the most obvious example of the flaking powder coat.

My only gripe with etrailer is shipping quality. This is a heavy item, well constructed, heavy duty, not lightweight. To ship this in a standard cardboard box without reinforcement is nuts. When delivered by UPS this box had gapping holes and part of the contents were protruding outside the shipping box. My UPS driver stated that such heavy items should be attached to a wood skeleton inside the box to keep from moving around during shipment. To my amazement all the parts were present, albeit banged up a bit with paint damage and gouging. So be aware that you may find your order in similar condition. etrailer responds to me with yada yada. Not real happy with this one but the unit itself is quite robust although a little black enamel will be required.



by:

Love this hitch system. I was hesitant to spend the money but I am so glad that I did. I have had the system for about a year now and it has impressed me every time I use it. I recently put a 3.5” lift kit on my truck and with the easy adjustments on the hitch system, I was able to accommodate for the lift in about 20 minutes. Would recommend



by:

First my truck and trailer sit and travel LEVEL, and I am pleased with the hitch after loosing one of the original “pins” while traveling(these are the pins that keep the sway bars on L brackets). I ordered the replacement “Pins” Now after a couple thousand miles, I do like how stable the truck and trailer are when other vehicles pass, the side push pull is much less. If the hitch came with the replacement “Pins” this would be a 5 Star Review.

I bought this in April '22 for our new trailer. The second day of our trip to Alaska, one of the Retaining Keys with the cotter pin fell off. It was while hooking up to our campsite that we saw it was gone and the spring bar bar had been free of mooring. Luckily we had a C Bolt and duck tape to hold the one sway bar without the retaining key and taped up the other to make sure it didn't fall off on the rest of our journey. When we called Blue Ox they sent two day to AK the two packages of the retaining key w/step. These turned out different than the ones that came on the TracPro and are thicker and shorter - I think these were suppose to come with the TracPro WD/Sway and should have been in the package when we got it. There is too much play between the sring bar and the L Bracket with the Retaining key that was in our order. Pictures for reference. If you order the Blue Ox TracPro, call make and sure you get the correct Retaining Keys with it, you should not have to buy them separately.



by:

Bought this to reduce rear sag in truck and you would think installing is pretty common sense but apparently it isn't. Instructions aren't very clear and since sad didn't go away at all, I'm guessing it isn't installed correctly. Instructions need to be MORE clear than they are otherwise you'll need to pay a professional to install it as I have no idea if it's correct or not.



by:

Easy to install haven’t driven the truck yet, but it seems to be doing exactly what it needs too.

Trailer hooked up with the blue ox the rear of the truck sits 4” higher than without. The nose drops about 3/4” compared to no blue ox. Massive difference in the right direction.

The photos are a 2021 4Runner no extra load in the back. Trailers 17’ ~3,500lbs max. I believe about a 350lb tongue weight and was mostly un-loaded.



by:

Jbars bend to easy and brackets move even when torque to speck



by:

the only problem I had was when the UPS man picked up the box all the nuts,bolts and hair pins fell out. other than that, I have received accurate advice as for the purchase and i am very happy with the hitch and its quality. easy to set yp and sturdy. tows great



by:

Works well. It's my first time with a distribution hitch, so I've no basis for comparison. I tow a 7200# 30' trailer with a 2007 F-150 (full-timer). It took a few trips to the scales to get things right, since I'm very close to my weight limits. Product arrived without the receiver (damaged box). Etrailer was very quick to provide replacement.

On assembly, I discovered that it was sent with incorrect mounting plates. Blue Ox expedited a parts kit. Overall, it seems to work well. I still have to be careful with wind, or I get pushed around on the road. It's mostly a non-issue.

I've traveled about 5-6K miles, and there is some noticeable wear, scoring, and rust developing where the torsion bars meet the trailer. These parts should be easily replaceable, as long as they're still manufactured. You may want to consider spares once you confirm that you have the correct bars. The friction points can develop metal splinters.

The pivots started showing wear after a long stretch of bouncy highway in Iowa. It was within the 1st 1000 miles, so I'll count this as break-in. I just readjusted the mounting point on the trailer at an overnight stop. I haven't had to adjust it since. The slop in the bushings makes for a greasy mess.

Wear gloves and put a plastic bag over the receiver when you remove it, or you're going to get greasy. Also, be careful of how low the receiver hangs down. I've caught it twice in uneven parking lots. I'm leaving it long, since it helps protect the tongue jack.

It meets expectation. Etrailer and Blue Ox provided excellent customer service. I still took one star, since I was on a deadline with work, and my plans got pushed back two weeks because of this. It shouldn't have happened in the first place, but the customer service from both parties was fantastic.



by:

Pulled to Dallas from Jackson, MS and back and they performed as advertised - sway was cut way dawn. When it did occur it was self correcting.



by:

The TrackPro parts list listed items 14 and 15 as 2-5/16" and 2" Hitch balls respectively, only the 2-5/16" ball was included and I needed the 2" hitch ball. Now I'm having to have the 2-5/16" hitch ball removed from the underslung hitch head assembly and get a 2" hitch ball attached. Looking forward to getting it all hooked up, I do expect a great improvement in the towing experience.



by:

I was told to purchase Blue Ox WDH from a friend. It seems to be very well built easier to attach and back up with still attached to trailer. Also seems to be smoother/quieter then other brands. It must be because of the load bars shape.



by:

These were easy to install on our 2021 Cherokee Wolf Pup trailer. The sway control is very good and the towing is now a very smooth safe ride. Backing is very easy. The only drawback is we have to raise the trailer tongue and truck pretty high with the jack to get them on easily. Lots of tension on the bars. Safety and smooth towing is why we purchased and for this i would recommend purchasing.



by:

Heavy and good quality



by:

Works great.



by:

Hello, The weight distribution seems to work fine. We took our traveler trailer on 2 trips since purchasing the trailer hitch and all the accessories. The sway is just frightening. We have not had any real wind, this was in May and July of this year. But super scary, and when a tractor trailer passes us, even just one, forget it. We are towing with a big Ford Expition also. I would not recommend this model. It was expensive and we will have to figure out what we are going to replace it with. Gil



by:

The difference with and without the Blue Ox is dramatic.
I pull a 25' Airstream with a 2011 Porsche Cayenne with a 3.6 liter 6 cylinder.

The Blue Ox balances the Cayenne to a degree that I didn't think was possible.

This hitch needs to be the first thing you buy when you get an RV.



by:

Item received timely and in good condition. Installation was rather simple, as the instructions were very good and everything for well. However, on of the pins was missing. This was a minor inconvenience, as I was able to find one at the closest hardware store 10 miles away. This is the only reason this is not a five star rating. Upon completion of installation, pulling my grooming trailer with the water tanks partial or full at greater than 55 mph was no longer a harrowing experience that I often wondered if I would survive. If you pull a trailer often, and it had swaying issues, this product is absolutely necessary.



by:

Just
Drove from Colorado to Oregon.
It worked better than our old one. Barely felt the big rigs as they went by.



by:

I received the hitch and the box was falling apart! Obviously the box did not hold up due to the weight of the product during shipment. I will inventory all pieces to make sure everything is still there when I go to open the box.



by:

Best investment I have made in my trailer other than the trailer itself. Works great

  • Setting Curt TruTrack Weight Distribution System Up On Trailer with Underslung Coupler
    I think the issue you're running into is being caused by the underslung coupler which the Curt TruTrack Weight Distribution System part # C17501 isn't really designed for. It's possible you can still get the system setup and working but it will never work as good as a system designed for this type of coupler like the Blue Ox TrackPro Weight Distribution part # BLU35FR which is what I recommend. It has the same sway control design and around the same price, the shank also has more adjustment...
