Weigh Safe hitch ball application

This Weigh Safe hitch ball has an easy-to-use, built-in scale that measures your trailer's tongue weight every time you tow. If the scale indicates that your tongue weight is too low or too high, you can adjust it before you head out so that you can complete your journey with peace of mind, knowing that your setup is safe. And towing trailers with different coupler sizes is a breeze thanks to the magnetic, clamp-on 2-5/16" ball adapter.


What is Tongue Weight?

Tongue weight (TW) refers to the weight that the fully loaded trailer exerts downward on the hitch ball of the tow vehicle. Tongue weight is typically 10 percent - and should not exceed 15 percent - of your gross trailer weight. For example, a 10,000-lb trailer should have a tongue weight between 1,000 lbs and 1,500 lbs. You can adjust the tongue weight of your trailer by removing or adding cargo, or redistributing the load on the trailer. The tongue weight should not exceed the capacity of your tow vehicle, your hitch, or any of your towing components.


Why is Tongue Weight So Important?

Weigh Safe helps ensure proper trailer tongue weight

Simply put, too little tongue weight can cause trailer sway and too much tongue weight can cause the tow vehicle to perform poorly. You may have difficulty steering, gaining traction, or braking when driving a setup that has too much weight pushing down on the rear of the vehicle. Ultimately, towing with an improper tongue weight can cause you to lose control of your vehicle or cause your trailer to separate from the vehicle.


Built-In Tongue Weight Scale

The gauge of the Weigh Safe built-in tongue weight scale

The Weigh Safe hitch ball's built-in scale signals you to adjust your load before you hit the road, resulting in a much safer and enjoyable towing experience. Before this hitch ball, gauging your trailer's tongue weight was a hassle. You had to rely on inefficient bathroom scales, make a trip to the weigh station, or purchase a separate tongue weight scale. But with the Weigh Safe ball's built-in scale, measuring your tongue weight is as easy as coupling your trailer to your ball mount. Simply attach the hitch ball to your ball mount and hook up your trailer. The weight of your trailer will push down on the hitch ball, which in turn pushes down on an internal hydraulic piston that sits on a bed of oil. When the piston drops into the oil, the pressure reading is sent out to the scale.


2" and 2-5/16" Hitch Ball Compatibility

A clamp-on adapter is included that increases the diameter of the hitch ball to 2-5/16". The adapter allows you to easily switch hitch ball diameters so that you can tow trailers with different coupler sizes. Both the 2" and 2-5/16" hitch balls are tested and rated at 10,000 lbs GTW with a 1,500-lb TW.


Clamp-on adapter installed on Weigh Safe hitch ball

Adjusting the hitch ball diameter with the clamp-on adapter is fast and easy. Open the adapter by pulling apart each side along the hinge. Then place the adapter over the top of the 2" ball and clamp it shut. Magnets inside the adapter will keep it in place. To remove, simply pull the sides apart and lift it off of the ball.


Simple Installation

Installation of Weigh Safe hitch ball

Installing the Weigh Safe hitch ball is simple. Insert the shank of the hitch ball through the hole in your ball mount and thread on the included lock washer. Next attach the female fastening nut, which includes the scale, to the hitch ball shank. Then tighten down the female fastening nut.


Superior Stainless Steel Construction

This Weigh Safe hitch ball is constructed of solid stainless steel offering far greater protection against rust and corrosion than standard steel hitch balls that are only painted or plated on the surface. The stainless steel shank is heat treated to increase its overall toughness, shear strength, and tensile strength so that you can safely tow up to 10,000 lbs.


The Weigh Safe hitch ball meets VESC V-5 regulations and is SAE J684 certified. These regulatory bodies - the Vehicle Equipment Safety Commission and the Society for Automotive Engineers - create standards for the design, construction, and performance of automotive and towing accessories. Weigh Safe has had this hitch ball thoroughly tested in simulation to ensure that it complies with these standards. The result is a strong, safe, sturdy product that is built to last.

Video Transcript for Weigh Safe Hitch Ball WSUN-1 Review

Speaker 1: Today we're taking a look at the Weigh Safe 2" and 2-5/16" Hitch Ball with a Built-in Tongue Weight Scale.This product is made in the USA and features a weight capacity of 10,000 pounds and a tongue weight capacity of 1,500 pounds. The hitch ball is designed for use with a standard ball mount for a draw bar that has a platform thickness of 3/4". The hitch ball provides a connection point for your trailer's coupler, and it does have the tongue weight scale that's built into the hitch ball to help you balance your trailer. This really helps promote safe towing, so that let's you know if your load needs to be adjusted before you tow, and it offers simple operation. This automatically provides a measurement every time you couple your trailer, so it's very efficient and hassle-free, and it eliminates the need for separate or commercial tongue weight scales.Now, when you connect your trailer to the hitch ball, the trailer will actually push down on the hitch ball, which in turn pushes down on an internal hydraulic piston that sits in a bed of oil. When the piston drops into the oil, the pressure reading is sent out to the scale to be visible by you.

This is designed and tested to let you tow trailers with different coupler sizes, so it is functional with the 2" and a 2-5/16" coupler. So, right here, this hitch ball's a 2" diameter, but you can also take the adapter, place it over, make sure it secures, and now you've just made it to where it can work with a 2-5/16" coupler as well.So, it's really nice design. It's very easy to use. It's made from a stainless steel construction, which is corrosion and rust resistant. The product's made in the USA.

I just want to go ahead and take the unit apart a little bit. I am going to show you how to install it onto a standard ball mount, but basically the pieces that come with it. It comes with the adapter. It comes with the tool needed to initially set it for the first time, and then you also have the 2" ball, has a shank. So, that's just like a standard hitch ball except it has that pin we we're talking about.

You get the lock washer and you get the scale portion. Now, the shank diameter, that's the diameter here, that's 1". When it comes to the actual scale, that's this portion here, this scale has an overall depth measurement of about 3", top to bottom is about 2-1/4, side to side is about 2".Now, when you're installing the Weight Safe Hitch Ball, it's very simple. I do have a ball mount here today because I just want to show you basically how it installs. It's really quick and easy to do.

What you'll need to do is insert the shank of the hitch ball through the hole in your ball mount just like that, and then the lock washer goes on the underside. Then, next you'll attach the fastening nut, which is just built right there into the scale. Place that on there. It threads into place. Then, what you'll need to do is you'll need to tighten everything down, and you'll need to torque to the specifications listed by the manufacturer in the instructions.Once the ball is attached, you'll use the provided tool. You'll tighten the ball set screw until the gauge located right here, until that reads 100 pounds, and then you'll back out the screw until the gauge has stopped decreasing. Then, your unit's ready to tow. All you need to do is determine if you're using the 2" or 2-5/16" setup. Now, always remember the ideal tongue weight should be 10 to 15% of your gross trailer weight. That's going to do it for today's look at the Weigh Safe 2" and 2-5/16" Hitch Ball with a Built-in Tongue Weight Scale.

The ball with built-in scale works perfectly and consistently allows me to load my car trailer with the correct tongue weight. Too much or too little and I reposition the car on the trailer. I highly recommend this product. 485148

I just received my Weigh-safe universal tow ball, (extremely fast delivery) and (thought I had a problem) with it. I learned after I called etrailer that operator error must have been an issue, because it was working as advertised when I checked it again. What can I say? . Of significance was E Trailer's response (by Sheila). "We'll fix the issue right away", she said. The problem was obviously me because when I checked again there was no problem. Excellent customer service. 497503

The idea is great but poorly executed. It works but every time I tow with it it loses calibration and I have to re-adjust for next time. I don’t tow a lot of loads where my tongue weight is that critical so I just deal with it and re-adjust/calibrate when I need it. 484996

I am impressed with the quality and machining! I just got it so haven't used it but it sure looks like a very satisfactory piece of gear. The 2-5/16" cover fits perfectly on the 2" ball. This thing is gorgeous! The directions are very precise and clear. It comes packaged very well and arrived within a few days of ordering. Overall, I am very satisfied with fit, finish, quality, and price. You're definitely getting your money's worth. It is most certainly NOT cheap Chinese junk! 340215

I purchased one of the first 'off the line' and was truly impressed, as the other reviewer stated, how the material and quality of workmanship stood out. I had great expectations....however.....in practice, the Weigh Safe mount with the built in scale didn't pan out. At hook up, it read my tongue weight perfectly. I do not recommend it's use with weight distribution hook ups including those with anti-sway. I have a Reese system that uses the trunnion design and a friction anti-sway.....which crushed the dial base and destroyed everything but the ball itself during a turn. This caveat to not use with W/D is now on the etrailer.com site where the experts answer questions, but I am dissapointed that the manufacturer didn'ttake the responsibility to have this in their marketing of the product up front. My recommendation for those with a W/D hitch purchase the separate tongue weight scale. 396542

I would have given it 5 stars; however, I don't like the fact that the 2 5/16 ball converter clamps over the 2" ball. It's held in place with magnets and can be easily lost or stolen if it's left on without a trailer hooked up. Other than that, it seems like an accurate scale. I only use the hitch to measure tongue weight. I don't usually tow with it because I'm concerns about environmental conditions ruining the gauge. 473724

The ordering process was so easy and the "shopping" was very descriptive and accurate once it arrived. It arrived in perfect time, just like they said it would and the agents at etrailer were excellent at keeping me abreast of the items and their arrival at my home. 518073

We use this scale to check out tongue weight before each trip with our camping trailer. We only use it to check tongue weight —not for towing. This ball works best for heavier tongue weights where you can use more of the scale’s indicator range—it starts at around 400 pounds and goes up to about 1200. We shoot for around 450 pounds so we are just able to register a reading which is not in the region where a highly accurate reading can be obtained. 497899
