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 2-Ball Mount with Built-In Scale Review

Today we're going to be taking a look at the Weigh-Safe line of adjustable aluminum ball mounts with built-in tongue weight scale, available in multiple configurations right here at Etrailer.com. Now a very common problem that we have that can sometimes make trailering unsafe is not having a proper load-out on our trailer or not having the appropriate tongue weight on the front. This gives us a really good example of it. We just picked this equipment up from the rental company, kind of tested it out to see how they load their trailer. This is a 9,000 pound combined load and it only has 350 pounds worth of tongue weight. Essentially what that means is that we've got too much weight too far back on the trailer. You can even see it here in the wheel wells with just a little bit of area here and you can see there's a lot more here in the front. That's putting a lot of excess strain and a lot of excess pressure on the tire and the rear axle.

That will cause this axle to wear out prematurely. Also if we don't have the appropriate amount of tongue weight pushing down on the rear of the vehicle it's not going to handle properly. We're not going to have the weight down on those rear tires to help us come to a stop quickly and safely. Another side affect of tongue weight not being heavy enough or not having enough downward pressure on that front end is that we can sometimes have sway behind our trailer. If you've ever seen a camper or a trailer going down the road improperly loaded you'll see it bouncing side to side. It's just not a safe situation. Weigh-Safe's got a great solution for that.

That's going to be our Weigh-Safe ball mount with built-in tongue weight scale. We've got a ball here. These are going to come in 2 or 2-5/16". It's going to press down on the hydraulic scale which is then going to register right here and let us know exactly how much tongue weight we have. As you can see this rental company gave us this trailer exactly how it sits and it's only at 350 pounds. To safely haul this any kind of distance at all we would need to reload this trailer and get appropriate tongue weight up here to the front.

Now the goal that you're looking for with tongue weight is going to be 10 to 15% of the total trailer weight. With this being 9,000 pounds worth of trailer we need to be somewhere between 900 pounds and 1,350 pounds. Now you'll see as we load up our trailer we'll just have somebody to keep on eye on our scale. As soon as it gets within the range that we're looking for, in that 10 to 15% mark, we'll know we've got our trailer loaded properly, we're ready to secure that load we'll head down the road much more safely than what it was before. Here you'll see our trailer properly loaded. You can see we've got about equal gaps with this front and this rear tire. It's going to help extend the life of all the components on our trailer and really going to improve the handling of that truck as we head down the highway. Now another common problem that we often see with trailering is when we have too much tongue weight.

It's going to give us kind of the opposite reaction of what we had before, putting a lot of that stress on this front axle now, going to do unnecessary wear on the tire, also build up a lot of friction in those springs, but where it transfers and where it's going to be apparent the most is when we have too much tongue weight on our trailer and we look at the truck. We're going to have a lot of squat here in the rear end, puts a lot of strain on that rear suspension on those rear tires, and it also draws the front end of the truck up. As it does that we're going to change the angle of our headlights so they're not going to be pointing exactly where we want them. Also it takes some of the weight off those fronts tires so steering and stability are going to be changed a little bit, also braking performance. Another issue we'll have a we had too much tongue weight is the tire wear. The suspension geometry is going to change and the outer edge of those tires is going to wear out much quicker than they should. This one we we're looking at is the 4" compared to the 6" drop that we looked at before, but it's going to tell us we've got approximately a 3,000 pound trailer load here so we want to be somewhere between 300 and 450 pounds of tongue weight. Now we can load up our UTV and know that we're safely going to be with him the right specifications of our ball mount. The shank portion itself here, this is going to be aluminum machined out of one solid piece. We're not going to have to worry about wells or any areas where we might have fatiguing or cracks. The main body of the ball mount itself, or the, actually, area the ball's going to ride in, that's again machined out of one solid piece of aluminum. Each of our pins are going to be constructed out of high-grade aluminum as well as the plate surrounding the lock. Then we've got our lock core. That's constructed out of stainless steel. That's going to keep it working good for a long time to come. We've got our pins here. We just want to slide these out. The nice thing about the pins is they're one unit. We don't have to worry about two different pins trying to get them in, trying to get them out. Makes it much simpler to adjust this up and down, and then you can see right inside there we're going to have the pin that actually holds our ball mount in. Then you'll see right down there there's going to be a plunger. That plunger is designed so when we have our ball in place our ball can push down on that. That's then going to register on the scale for us. The hitch balls are a solid one-piece stainless steel construction. That's going to give us superior corrosion resistance. Also the plunger at the base is made of the same material. You might have a little bit of a concern with the mix of stainless steel and aluminum. Weigh-Safe has thought about that and on the aluminum they've put a galvanic coating on there. That's going to prevent our stainless steel and our aluminum from causing each other to corrode. It's really nice. As you can see they've really put a lot of energy into giving us the highest grade materials that are available, giving us a very strong yet lightweight corrosion-resistant product. That's why they're going to offer you the limited lifetime warranty regardless of where the point of failure might be, which we haven't seen yet but if it does happen send it right back to them. Another great thing, these are made right here in the United States so you know that you're having somebody that takes pride in their work, they're doing a good job to get you something to work that's going to work very effectively. Now regardless of the size in drop or in shank that we decide on, the ball mount's going to come with both the 2" and the 2-5/16" ball mounts. Now if you decide that you need 1-7/8", this is part number WSBL. Now as we go up in size the weight capacities are going to become greater. Now for the 1-7/8" we're going to have a 7,500 pound maximum gross trailer weight capacity whether we're using the 2" shank or the 2-1/2" shank. When we move into the 2" ball that's going to go up to 8,000 pounds on either the 2" or a 2-1/2. Now the only slight difference that we have is going to be on the 2-5/16" ball. It's stamped at 14,500 pounds. That's going to be for use with the 2-1/2" shank. If you go to the 2" shank that capacity's going to be limited to 10,000. Now depending on which size shank you're going to use, if you're using the 2-1/2" you'll see the scale's customized for that. Once it gets up to 2,200 pounds, which is the maximum tongue weight rating of the 2-1/2" design it's going to give you that red area. That way you'll know too much tongue weight, we're exceeding the limit of the ball mount. Same thing for our 2" version here. You can see though it's going to be a little bit lower. That's at the 1,500 pound mark. That's the maximum tongue weight rating for the 2" configuration. We don't want to exceed that and it's nice that it's going to give us a visual cue if we do. Now as we put this together what we're going to do is lineup that oblong hole with our pinhole. We can slide that pin in and through. Now we've got, you can see around the ball, just the slightest bit of a tolerance that's been built in right here. That's going to be sure that that ball has room to move up and down and it won't get bound up inside of there. You can see it's a little bit of wiggle room. That's going to allow that scale to work. We'll side the ball mount portion up and on the shank, pick whatever drop it is that you require, simply slide that in and turn it. That's going to keep everything nice and secure. Now a locking hitch pin that we recommend is part number WS06. This comes with both the locking hitch pin and the dual locking pin assembly. This is going to give you a second dual locking pin assembly but this is the perfect solution for having both of your locks keyed alike so you don't have to search for multiple keys. You're making an investment in safety with these and we don't want them to disappear. Now we're going to get a couple quick measurements for you so you know the distance from the center of our pinholes to the center of our ball. This is going to help ensure that this is going to work for your application. We'll start with the 2" shank model. It's going to have two pinholes. The first one here is going to be about 8-3/8" to the center of our ball. The other is going to be around 9-1/2". Now onto the 2-1/2" version. We're going to have about 8-3/4" from the center of our pinhole to the center of our ball. Regardless of the ball size that you're going to use this will not change. Now when it comes time to adjust our drop or our rise it's a very simple process. You'll just take your included key, placed that in, turn it 90 degrees. At that point you'll see our double pin kit. It's going to come right out. We don't have to wrestle with pulling multiple pins or trying to get multiple clips undone like we have to with most adjustable ball mounts. With the pin set up the way it is, the dual pin and all the options that we have, we'll be able to adjust this incrementally all the way from its highest setting here, which would be just about dead even with the receiver tube all the way down to that 4" drop. Once we get the selection in there that we want that pin's just going to slide back in and we can lock it back up. Now for storage of your Weigh-Safe ball mount if you don't want it in the position that you have it here to where it's out, we can also store this underneath the vehicle. With the 4" drop we'll have to invert the ball or have the ball face down. With the 6, 8, or 10 it can be stored in its upright position but essentially we just bring that around to the back side. Get that raised up. Slide our pin in just like that and re-lock it. That's going to really reduce the chance that we're going to knock our leg on it or bump our shin as we're walking by. That's going to complete our look at the Weigh-Safe line of adjustable aluminum ball mounts with built-in tongue weight scale.

I like the idea of being able to know how much tongue weight I have while loading. I can readjust the load as needed when loading. This product gives me that ability. A quality product that was shipped and received as stated from etrailer. 436815

- WS4-25

I would like to Thank You for the very prompt delivery of my order which I received October 12. I placed my order online on October 9th, 2017. I am very pleased to see such a quick delivery, excellent service. I came across your product by luck I might add, while searching for hitches. I am the owner of BasinBayou, LLC. We are a catering/Food Truck company in Texas. We are in the process of having a custom built Food Trailer fully equipped. I wanted a hitch that I knew would handle the load. Perhaps a bit of overkill some might say, however I believe in quality over any price for long term usage. The craftsmanship is absolutely a thing of beauty. We are due to pickup our new trailer by the end of this month from the manufacturer in Florida. I will keep you posted and send pictures of the hookup with our new trailer. Please feel free to use this as a review for a compliment of your excellent service. 459688

Never has shown young weight ! Piece of junk ! 323571

We have found that the Weigh Safe ball mounts are reliable and provide accurate weight readings. They do have a limited lifetime warranty against manufacturer defects. I have forwarded this to customer service, who will be in contact with you to assist with your order.

This is the nicest hitch I have ever owned. I tow a boat and cargo trailer with about 4" difference in hitch heights. Prior to this hitch I had to select a compromised height that wasn't right for either of my trailers; now I can quickly and easily adjust for the correct hitch height on each. I have been concerned that I had my tongue weight correct and I now can confirm the tongue weight and be confident I have both trailers loaded correctly. I did my homework prior to buying this hitch so I knew this hitch was quality, but I was pleasantly surprised at just how well the parts are machined. The finish is excellent. One of the big selling points was the ball assembly locked to the rest of the hitch. I'll never have a ball mount assembly from another manufacturer. 254503

Awesome hitch, weight scale is great and the exchange of the 2 inch and 2 1/2 hitch ball is a easy exchange , only little issue is the hitch an receiver is a little noise but with weight on it is quite, I use it to pull my 4000 boat and my 10000 lb desert trailer easy 438847

- WS4-25

Easily one of the prettiest ball mounts I've ever had. This kit included a locking dual pin, which made the purchase of the separate locking dual pin an unnecessary expense, so I guess I now have a spare, but otherwise everything was as advertised. I was hoping that I could flip the ball mount and reverse it under the receiver, and I can, but only in the lowest set of holes. The low profile socket head fastener that goes into the piston assembly for the gauge contacts the reinforcing ring on the receiver hitch just before the 5/8" pin can be installed...I may relieve the reinforcing ring slightly (less than 1/32") to gain the 1" of ground clearance in this configuration when not towing. 410993

- WS4-25

Works great, easy to adjust. Love having the built in scale so you know your tongue weight! I ordered one with too large of drop, called customer service and they quickly sent me another one and included a shipping label for the return. Enjoy working with this company! 346054

- WS4-25

If there was an option for 4.5 I would use that. I really like the hitch. The hitch balls and aluminum hitch are very well made and almost a work of art. It functions very well as a hitch and I have no corrosion or signs of deterioration after a year of pretty hard use. My only two complaints are: 1. The scale doesn't work well for lighter trailers because there has to be about 300 pounds of tongue weight before the thing starts to register. So if you want to make sure you have 10% tonge weight on a utility or jetski trailer you are out of luck. 2. I have to clean out the area where the ball sits on the scale or it quits working. Not a big deal, but kind of messy. Except for those two things, I really love the hitch. 340544

- WS4-25

This is one beautiful product and confident it will last my lifetime and more. One issue came up after opening the package and the scale was not color coded as depicted on your site. Called eTrailer and spoke with Patrick. This gentleman took up my cause and got me answers as to why. Very professional and so concerned to satisfy the customer. The factory in Utah is sending out a replacement at no charge immediately. I am still giving the product and service a 5 star because of the way Patrick and Lindsay at the factory handled my issue. My hats off to both of these representatives of eTrailer and Weigh Safe Manufacturing. 326650

I really like being able to see how much tongue weight I'm putting on the vehicle when I load it. What a great invention! 298114

  • How to Determine What Rise or Drop Weigh Safe Adjustable Ball Mount Needed for Livestock Trailer
    The best thing to do is hitch the trailer up loaded using a ball mount you currently have that puts you pretty close to level or borrow one. When the trailer is hitched up, make note of how much squat occurs. Measuring the before and after height of the wheel wells at the back of the truck is the easiest place to do that.

    The Weigh Safe 2-Ball Mount w/ Built-In Scale # WS4-25 that you referenced cannot be used with a weight distribution system as the holes of the shank do not match the standard hole dimensions that WD shanks will use, and also the ball mount platform does not have any way to attach to spring bars.

  • How to Pick Out Weigh Safe Adjustable Ball Mount for 2-1/2 inch Hitch for Ground Clearance
    When we installed the Curt hitch # C15810 on a similar 2007 Ford F-250 to your 2006 Ford F-350 we found that from the top of the hitch opening down to the ground measured 20 inches. The Weigh Safe Ball Mount part # WS10-25 is a great ball mount but it would hang down 13 inches from the top of your hitch opening putting it about 7 inches off the ground. A better option for ground clearance would be the same ball mount but with less drop part # WS6-25 as this would sit 4 inch taller....
