Features to know about

Keeps Every Trailer Level: 6" Drop or 7" Rise

When you’re hauling different trailers, getting the height right makes a huge difference in how smoothly things ride. This Weigh Safe hitch gives you up to a 6" drop or a 7" rise with 1" increments, so you can match each trailer’s coupler height for a proper, level tow. The adjustable platform slides on the 2-1/2" shank and locks in place with dual pins, keeping things solid once set.

Takes the Guesswork Out of Tongue Weight: Built-In Scale

Balancing your load used to mean juggling bathroom scales or heading to a weigh station. With this hitch, the built-in tongue weight gauge shows how much force your trailer puts on the hitch ball the moment you connect it. The clear, automatic reading makes it easy to know when your setup is dialed in before hitting the road—no extra tools or steps required.

Strong Enough for Heavy Loads: Up to 18,500 lbs GTW

Tow with confidence using a mount made for serious weight. The solid 6061-T6 billet aluminum shank and platform keep strength high while staying lightweight. The stainless steel balls handle heavy-duty pulling—rated at 18,500 lbs gross towing weight on the 2-5/16" ball and 10,000 lbs on the 2" ball, with a maximum tongue weight of 2,200 lbs. Everything is SAE J684 certified and VESC Regulations V-5 compliant for proven safety.

Stays Secure and Silent: Locking Dual Pins and Hitch Lock

Nothing’s worse than rattles or loose parts when towing. The keyed-alike locking dual pins hold the ball mount platform tight on the shank, while the included hitch receiver lock secures the shank itself. Together they keep movement to a minimum—no noticeable play between the ball and platform—and deter theft when parked.

Puts Convenience First: Two Balls and Stowable Design

Switching between trailers is simple thanks to the included 2" and 2-5/16" stainless steel balls that swap out with a quick pin change. When you’re done towing, flip the platform under the shank for clean storage that stays out of the way. It’s an easy way to keep your setup ready without removing it from your truck every time.

I've used this for 12 months on a wide range of trailers 3000-15,000# and it's a great product. At the Cat Scale last week I checked the tongue weight at 1300# on the gauge and it was correct. The range of heights is great with trailers from car carrying box trailer to very tall ag trailer, it works with my 1 ton for all. The light weight makes it easy to mount and dismount 1 handed.
by:
Exactly as described, works well!
by:
This Weigh Safe drop hitch is very well made. It will serve my purpose with the 2" and the 2-5/16" balls.
by:
If I could find the keys to my original one I would not have ordered it. But I couldn't do I didn't hesitate in ordering a new one. But I forgot to get the 1 7/8 ball to go with it. Will order it sometime soon.
by:
Love it! I have the smaller 2" and have had it for several years and I will not be without one going forward to be able to know on every trailer how much tung weight I have.
by:
Everyone was very helpful and kept me informed on any changes on delivery of the product. Thank you for your professionalism.

I was very pleased with the fit and finish of the Weigh Safe hitch and scale. I also purchased a standalone tongue weight scale and was happy to see both of them give me very identical readings. I would like to see an additional pin on the height adjustment pin so it’s not relying solely upon the key lock. I would certainly recommend this hitch for someone that wants to know their trailer tongue weight. Will definitely cut down my trips to the CAT scale and provide a more accurate measurement. I can also move weight around and see direct results on the tongue.
by:
I downloaded the APP. It took me awhile to figure out how the App work. I think I have it figured out now. It would be nice to give a QR code to a video on how the APP set up works. The Hitch overall is made very well.
by:
It's a beast! Heavy duty and everything fits together perfectly. Can't wait to haul my camper with it and see what my actual tongue weight is.
by:
Received my new hitch today and can’t be happier with the build quality. Excellent customer service! Can’t wait to test it out on our next trip.

Glad you like it, JT! What is the next trip you have planned?

by:
I use this to haul a car on a trailer with my Rv and tongue weight is very important because I don't want to flex the frame, my rv has a very long distance from the axel to the bumper. And with this hitch I am able to place the car on the trailer and know the tongue weight for each position I put the car in. I was able to level the trailer as well. This hitch is well made.
by:
The weight scale is not registering the tongue weight. It stays on zero.
