    Video Transcript for Review of Weigh Safe Replacement Stainless Steel 2-5-16 inch Tow Ball - WS39ZR

    Hello, neighbor. Steven here with etrailer.com. Let's take a look together at our Weigh Safe Replacement Stainless Steel 2 and 5/16th inch tow ball for all shanks and sizes and styles. That's right folks, this replaces the hitch ball that is a 2 and 5/16 inch. For your Weigh Safe ball mount, it does fit inside the hitch ball mounting platform. It provides an attachment point for your trailer's coupler.

    It is stainless steel construction. It's very heavy duty. It's gonna resist corrosion. Now with the Weigh Safe stuff, you can see it printed on the front too. It says the rating is on the drawbar, so the rating on their stuff is gonna be the drawbar itself.

    So make sure you check your drawbar. That's what it's rated for. Again, a nice 2 and 5/16 inch ball, just a replacement ball for your Weigh Safe. I'm Steven. Thanks so much for watching and have a great day.

    Took weeks to receive, and I need to take them to a machine shop to turn the stub down, as they are the wrong diameter for my hitch.

    I bought this ball to round out the trifecta for the Weigh-Safe 2-Ball mount-2 1/2", 6" drop-7"rise 14.5K Hitch, so I can haul any trailer I may need to haul. It's the ball pictured in the mount.

    I havent used it yet, but I think itll be fine-based on the ruggedness of the 2 and 2 516 balls.

    Purchased this 1 7/8" ball to go with my ball mount that came with 2" and 2 5/16" balls. Quality of this product and the ball mount is exceptional and I always recommend this product and etrailer to any asking my opinion of a good ball mount.

    Thanks for checking in. Shows superior customer service. I love this ballmount! I use it quite often with the 2-5/16 and the 2 balls. I also have an 1- 7/8 just in case LOL!. The scale truly is an aide in establishing an appropriate tongue weight. The only concern I have is that I feel the mount has loosened in the receiver. I remember the mount when new was fairly snug. Now I can lift the mount about 1/4 while it is in the receiver. I hope that will not be an issue as I move forward in years. Even with that, I still recommend this product, and etrailer.com to all who ask.

    Hig quality that matches my original weigh safe hitch.
    by:
    I purchased this to mate with he 25-10 hitch. It rounds out the set that includes that 2 inch and 2 5/16 ball. The combo is a perfect fit for my stock Ram 3500 4x4 (man are these trucks tall). I have the 6.4 gas engine so the 14,000 capacity of the hitch (when paired with the large ball) matches perfectly with my truck's towing capacity. I still have to watch the hitch weight though as this hitch is way more capable than the 1400 lb tongue weight on my bumper. My weight gauge differs slightly in graduation and color (mine has no green color indications to indicate a safe range or red for overload. The gauge has black and white graduations). Its not an issue, just thought buyers should know. This is a manly set of gear. Im positive that this will be the last hitch I ever purchase.

    This is a perfect match to the hitch. With all three balls there is nothing I cant tow. Excellent piece of gear!

    by:
    I bought this ball to complete the set for the WS6-25 2 ball hitch so I will be able to pull any trailer that takes a 1 7/8 inch, 2 inch, or 2 5/16 ball. This ball appears to be the same high quality as the two that came with the hitch. Very happy with my purchase.

    Ball shows only a small amount of wear in the form of scratches, none are deep. Still very happy with this purchase.

    by:
    The 1 7/8" ball that fits the Weight Safe Ball Mount is a necessity if you ever pull a small, lightweight trailer. It should be standard with the ball mount kit. Why offer an incomplete kit? With that said, the ball is of substantial build and deserves 5 stars. I expect it will outlive me.

    The optional 1-7/8 ball works as designed. I still think it should be included with the kit instead of being optional/additional cost.

    I added this well made, quality Hitch Ball to complete my collection of Balls for my Weigh Safe Hitch system! The price point was right and customer service is outstanding also.

    I am sorry to hear that Jason. I see that this only works with version 2, did you click the link above to see what version you have? Can you sent me pictures of the scale, and the measurement of the slot so I can verify that you have version 2? You can send the pictures by responding directly to the email you receive. I look forward to hearing from you.

    @KateF Weigh Safe does not make a 2" ball for their Weight Distribution Towing System. They sell replacement balls for their regular hitches. The shaft is a different diameter. I would have hoped they would design one thats interchangeable.
    by:
    So far so good. The ball has been great with one exception. It is constantly getting covered in a gray/black coating. I have to keep a rag in the truck to wipe it down before storing or changing a ball. I really like the ability to not only chose 1 7/8, 2 or 2 5/16 balls but also to adjust the height for each trailer. I use the weight measurement when loading snowmobiles or 4-wheelers on the trailer to make sure I get enough tongue weight. My Weigh Safe hitch does seem to underreport the weight by about 50 lbs.
    by:
    I drive a Wrangler with a low tongue weight limit. This WeighSafe hitch makes tongue weight easily readable. It's not cheap, but I like the use of non-corrosive materials and thick aluminum parts. The balls are solid stainless steel, not just chromed like cheaper hitches. I bought the optional 1-7/8 ball so I can travel with all three sizes. I have had many people ask "what's that gauge on your hitch", It's fun to answer that it's a live tongue weight measurement.
    by:
    I wanted the Weigh Safe Ball Mount so I could stop guessing what the tongue weight was. Now I can tow with confidence that my trailer is properly loaded and balanced. The unit is obviously well-made and heavy-duty. My only complaint is that since there are so many "moving parts" (the receiver bar, the ball mount, and the ball) the whole assembly is loose. This causes a lot of movement and noise while towing. Nevertheless, the looseness doesn't seem to affect towing performance.
    by:
    10" drop/11" rise changeable ball hitch. Excellent, efficient, practical. Thats the "one word" I would use to describe this hitch. The barrel lock on both the adjustable hitch, as well as the optional locking hitch pin are solid and unclunky. The ball changes take seconds too. I have 3 different trailers with different tongue heights and ball sizes. Now I don't have to unmount one threaded ball for an other one. No more impact gun, or, the inconvenience of not having one available for ball changes. No more trailer tilt while towing either. This hitch makes towing a more convenient, enjoyable exercise. It's also a work of art. 5 stars all the way.
    by:
    I lost my original hitch ball that came with my original hitch. Went back to etrailer and luckily i was able to order the ball itself without having to purchase the entire hitch. Thank Etrailer for making it simple!
    by:
    Each of the Weigh Safe stainless steel hitch balls are high quality. I ordered the 1 7/8" hitch ball to round out my towing ability when I purchased the Weigh Safe system. Although the original shipment had the wrong 1 7/8" hitch ball, etrailer corrected the error by sending me the correct ball.

    Nice piece to complete the hitch now with all 3 balls, fast delivery

    Excellent

    by:
    It's a great system and I love having the three most common ball sizes so I'm ready to tow just about anything. With a load-distribution hitch and a 2.5" receiver (and a reduced sleeve to 2"), I'm the friend everyone wants to have! You've made it easy to tow safely and with the confidence that the job will get done right!
    by:
    Bought this to go with my WeighSafe drop hitch. It came with 2” and 2-5/16”, so I added this just in case....never know when you might need to tow a small trailer and need the small ball. Drops right in to the hitch head.
    by:
    I was told that the weight safe was to much money. I bought one of those that has 3 balls system that was heavy chuck of steel,and it didn't have the drop I needed. The weight safe works great it has the drop I needed. And I don't need a tractor to help me put it on my truck. It's worth every penny that I paid for it. And the two people that told me weight safe was to much money has bought them a weight safe.
    And I also like the gage to see how much tough weight I have. Buy one you won't regret it.
    by:
    Impressive workmanship. Very heavy, solid unit. The components fit together perfectly, no slop - excellent machining. It will make switching between my camper, boat and trailer, and car trailer with the proper tongue weight easy and worry free. I can even hook up to friends equipment easily. I just like the peace of mind that comes with knowing a proper tongue weight is always in place. I bought the 1-7/8 inch ball just in case. I also bought the hitch lock and pin lock set so the unit doesn't get "misplaced".
    by:
    I order this for my weigh safe trailer hitch. Now I have all three sizes so I can pulll all of the trailers I own and I only have to switch the ball out.
