Weigh Safe ball mount coupled to a trailer

This Weigh Safe ball mount 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 the peace of mind that your setup is safe.


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 ball mount'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 ball mount, 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's built-in scale, measuring your tongue weight is as easy as coupling your trailer to your ball mount. Simply hook-up your trailer to the Weigh Safe ball mount just as you would any other ball mount. 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.


Easily Adjusts to Fit Your Setup

Weigh Safe ball mount has adjustable height

Adjusting and setting up the Weigh Safe ball mount to work with your specific trailer is easy. First, unlock and pull out the dual pins and remove the platform from the shank. Next, pull out the hitch ball retaining pin from the back of the platform and insert either the 2" or 2-5/16" hitch ball. A 1-7/8" hitch ball (WSB-L - sold separately) is also available. Then reinsert the retaining pin to secure the ball to the platform. Replace the platform and slide it along the shank to the desired height. Insert the dual pins and use one of the included keys to lock the pins in place.


Weigh Safe ball mounts installed in drop and rise positions

The Weigh Safe ball mount can be used in either the drop or rise position to best suit your application.


Superior Aluminum and Stainless Steel Construction

From the first moment that you lay eyes on the Weigh Safe ball mount you'll see that you're getting a superior, well-made product. The Weigh Safe's shank and ball mount platform are made entirely of 6061 T6 billet aluminum, which is the same material that is used to build aircraft components, automobile frames, and freight liners. This type of aluminum is known for having superior strength while maintaining its light weight, which makes it highly desirable over hollow steel components. 6061 T6 aluminum is also rustproof, which means the Weigh Safe hitch will maintain its clean, shiny, and impressive appearance for years to come. And the hitch balls are made of solid stainless steel, offering far greater protection against rust and corrosion than other steel hitch balls that are only painted or plated on the surface.


The Weigh Safe ball mount 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 ball mount 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 Ball Mounts - Adjustable Ball Mount - WS8-3 Review

Today we're going to take a look at the Weigh-Safe Adjustable 2-Ball Mount with the built in tongue weight scale for a 3" hitch. It has an 8" drop, an 8" rise and a 21,000 lb weight capacity. This adjustable ball mount, with included hitch ball to let you hook up your trailer to your tow vehicle. The shank portion right here, is a little slide into your 3" hitch receiver opening. Then the hitch balls is what will provide the connection point for your trailer coupler. The Weigh-Safe ball mount has this easy to use built in scale here. This will measure your trailer's tongue weight every time you tow. Now if that scale indicates your tongue weight's too low or too high, you can adjust it before you head out so that you can complete your trip with the peace of mind knowing that your towing set up is safe. Weigh-Safe is the only ball mount that has this built in scale to measure the tongue weight.

You might wonder why is tongue weight so important; well too much tongue weight can affect your driving maneuverability. Of course, too little tongue weight and your trailer might fishtail, swing into other lanes, or might just come off the ball. Tongue weight's typically 10-15% of your gross trailer rate. An example is, if you got a 10,000 lb trailer, the tongue weight should be between 1,000-1,500 lbs. You can adjust the tongue weight of your trailer by removing or adding cargo, or just redistributing the load that's already on the trailer. This Weigh-Safe scale is linear rated up to 22,000 lbs. The marks on it on the gage are in 100 lb increments.

Basically, just to measure your tongue weight is as easy as just coupling your trailer to this Weigh-Safe ball mount. Simply hook the trailer to the ball mount just as you would any other ball mount. The weight of the trailer will push down on the hitch ball, which in turn will push down on an internal hydraulic piston that will sit in the bed of oil. This piston is inside the mount right here, so when that piston drops into the oil, the pressure reading is sent to the scale. You can see it's an adjustable heighth ball mount, so this will let you tow trailers of different heights with the same vehicle. The ball mount platform will just slide up or down the shank, and you secure it in place with the included dual locking pin lock right here, as opposed to some of the adjustable ball mounts that use individual pins and individual clips.

That can be a hassle to line everything up. The two keys you can see are included. We just put the key in to unlock it, just turn it to unlock it. You can see they slide right out all in one piece, very easy to do. Basically this Weigh-Safe ball mount, you can use it in either a drop or a rise position to match the height of your trailer. Basically you can see, you put it up to what's adjustable, so you put it to what heighth you need. Then because you can use an either drop, this is the drop position; you can turn it around and use it in the rise position just like that, either one. In each position the maximum drop or the maximum rise is going to be 8".

If we measure from the top of the shank to the top of the platform, so this is the max rise, there's your 8". If we turn it back around and do the max drop, there's your maximum drop; and same way, it's going to be right at 8". You notice the holes here, there at 1" increments center to center. You have an incremental heighth adjustment of 1". Now I do want to give you the distance from the center of the hitch pin hole to the center of the hitch ball. If we slide that up, and we take a ruler and go center of the hitch pin hole to the center of the hitch ball is 8 3/4". You notice it does come with two different size hitch balls to let you tow trailers with different coupler sizes. This one is a 2", has an 8,000 lb rating, which is stamped on the top. This one's a 2 & 5/16" with a 21,000 lb rating. To switch the balls is very simple, I'll show you how to do that. You just look right in here on the ball mount platform, you can see there's a retaining pin that holds the ball in and a ring on the end. You just pull the ring, the pin will come out. You take the ball right out, take the larger one, line the hole up with the hole in the ball mount, drop it in place. Line your retaining pin up, push it all the way in. Now it's locked in and you're all ready to go. You can just put it back on the shank. Very simple to switch the balls out. Now the balls themselves are stainless steel, so they are corrosion resistant. The hitch shank portion and the mounting platform, they are made of a 60-61 T6 aluminum. That's used in aircraft construction, so it will give you superior strength and durability. The application on this is 3" by 3" trailer hitch receivers. Gross towing weight capacity will depend on the ball you use; if you use the smaller 2" ball, it will be stamped 8,000 lbs. If you use the larger 2 5/16", 21,000 lbs. Maximum tongue weight is going to be 2,200 lbs. This part is made in the USA. That should do it for the review on the Weigh-Safe adjustable 2 ball mount with a built in tongue weight scale for a 3" hitch. Has an 8" drop, 8" rise and a 21,000 lb weight capacity.

Overall I like the product. It does what I need it to do. Easy to swap between balls for different trailers. Only negative is the weight scale stopped working after about the third use. 475101

I love the hitch, I've had other similar hitches but this one rules all. I'm so glad it's available in 3". 717357

Won't actually tow with this until next week. But, folks, this is a big solid ball mount. It fits perfectly in the factory receiver on my 2019 F350 DRW. I got this one because the scale should take a lot of the guess work out of the tongue weight calculations. And, let's face it. This thing looks sharp on the back of the truck when you arent using it. 658971

Just received the hitch yesterday and have not used it yet. Initial thought of it, IMPRESSIVE! There were a few small gouges/scratches on the unit, I think from the keys resting under it during shipping and the "Weigh Safe" sticker is super crooked. Obviously, neither will affect the function of it, but it looks a little sloppy after spending $350 for a trailer hitch. I look forward to using the hitch to see how it actually performs. Based on initial appearance, and not actual function, I give it 4 stars. 488039

First off I paid for the overnight shipping and it was true overnight shipping. Within 24 hours of ordering it was delivered. Since there are not many 3" hitches on the market yet, I was scepticle about the Qaulity of those that were. I had never bought or heard of weigh safe products before so I was not expecting much. Yet when I saw the qaulity of the hitch as I removed it from the box in the future I will not be hesitant to buy weigh safe products. From the easy key set up to move the height adjustment to the ease of changing the size of the ball with a pull of a pin and with it being made out of aluminum so no rusting or repainting what more could you ask for. Thank you again e-trailer for the fast shipping!!!!! A+A+A+ 346443

This is my second purchase of the Weigh Safe hitch. I had to buy a smaller one because I traded trucks and the 3" shaft was too large for the new truck's receiver. The first one I had was used around 3 years and I was 100% satisfied with it so it was an easy decision for this purchase. 679829
