Features to know about

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

When you’re switching between different trailers, each one sits at its own height. This mount takes care of that with a full 6" drop and 7" rise, adjustable in 1" increments. The sliding platform locks solidly in place with dual pins, so you can line up your trailer level every time for stable, even towing.

Handles Big Loads with Confidence: Up to 21,000 lbs GTW

Heavy campers, boats, or loaded equipment trailers are no problem here. The 2-5/16" ball is rated for 21,000 lbs gross towing weight with a maximum tongue weight of 2,200 lbs, while the 2" ball is rated for 8,000 lbs. Both are stainless steel for strength and corrosion resistance, giving you solid performance season after season.

Quick Trailer Changeovers: Dual Stainless Balls in One Mount

If you tow different trailers with different coupler sizes, this setup saves time. The platform carries both a 2" and a 2-5/16" ball on opposite sides—flip it over to switch sizes and lock it back down. No loose parts to track down or swap out, just pull the pins, flip, and go.

Built Strong but Easy to Handle: Solid Aluminum Shank

The shank and platform are made from 6061-T6 billet aluminum, giving you plenty of strength without adding unnecessary weight. It’s a solid block design that stays rigid under heavy loads while keeping the overall mount lighter than comparable steel versions.

Stays Secure and Protected: Keyed-Alike Locking System

This mount comes ready with built-in security—locking dual pins hold the adjustable platform in place, and a hitch receiver lock secures the shank. All locks are keyed alike with four keys included, so your setup stays safe when you’re parked or on the road.

Video Transcript for Review of Weigh Safe 180 Hitch 2 Ball Mount 3 Inch Receiver - WS75RR

Hi, everybody. Andy here with etrailer.com. Let's take a look at this Weigh Safe 180 hitch with two ball mount for your three-inch hitch receiver. Now, this 180 hitch is going to slide into your three-inch hitch receiver and it's going to give you a two-inch and 2 5/16 inch double-sided stainless steel tow ball. So this is going to make switching your tow ball sizes very easy. And this is also going to give you a maximum drop when you have the shank in this orientation of six inches.

And then when you flip this over, you'll get a maximum rise of seven inches, and you'll have a incremental adjustment of one inch, giving you that height adjustability that you're looking for so you can tow trailers of different heights with the same vehicle. Now, when you use the 2 5/16 inch hitch ball, you're gonna get a gross towing weight of 21,000 pounds. And when you're using the two-inch ball, you'll get a gross towing weight of 8,000 pounds. And this has a maximum tongue weight of 2,200 pounds. And the hitch itself is constructed of aircraft-grade aluminium, giving you superior strength and durability.

The solid block construction is going to give you greater strength than any hollow steel competitors which will also maintain the lightweight. And this is gonna be rust-proof and the finish is going to remain clean and so it's gonna stand the test of time. So even though this is lightweight, this is gonna be very durable. It's gonna hold up really well for you. Now, the balls here are stainless steel as I mentioned, and this does feature a dual pin slider lock that's going to make adjusting the height and switching the tow ball size is very easy.

Let me go ahead and give you a brief demonstration of that. So I'm gonna grab the keys here. I'm gonna remove this black rubber cover that's provided to protect that keyway from dirt and debris. So let me go ahead and insert the key here. I'm gonna give it a turn and then that's going to allow me to remove this slider just like that.

And while I have this out, I wanted to mention that the pins here are aluminium, the housing is aluminium, and then the lock there is plated steel. So this is going to be very durable as well. It's gonna hold up against that rust and corrosion. So you can see that this is going to be able to slide up and down very easily. You're not gonna have any problems. So I'm gonna go ahead and switch this from the two-inch ball to the 2 5/16 inch ball just like that. And then you can just get that adjustment that you're looking for and you'll be good to go. So let me turn this around here and I wanna line up those holes and then put my pins back in just like that. And if you notice, everything is just really a smooth operation. You're not gonna be at the back of your vehicle, struggling to get the adjustment or the ball size that you need. It's gonna be a very fast adjustment, everything is gonna run very smoothly for you. Now, you also are going to get this locking hitch pin and this is key to like, so you're gonna get four keys. And the idea is, one key is going to operate the dual pin slider lock and also the hitch pin lock. So you're not gonna have to be juggling keys with this. And lemme give you a brief demonstration of how this is going to work. You'll just insert one of the keys, give it a turn, and then that's going to allow you to unlock this. Now, I'm gonna go ahead and lock the head back up here, remove the key. And if you notice, it does come with this cap here to protect that keyway. What I really like about this lock is, you do not need to keep the key inside of the head here to lock this back up. So all I'm gonna do is slide that back through and then I replace the head and now it's locked. So a very easy operation, it's gonna be very convenient to use. So four keys included, all key to like. Let me give you some measurements here just so you have a good idea of the size of this unit. My first measurement is gonna be from the center of the first hitch pin hole to the center of the ball. It's gonna be about 8.5 inches. Moving to the center of the second hitch pin hole, about 9 5/8 inches. And then, from the center of the second hitch pin hole to the back of our shank, about 1 7/8 inches. This is V5 and J684 certified. And I think that's gonna wrap up our real quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

This hitch has a stainless steel double-sided tow ball, so switching sizes is a breeze. Tow up to 8,000 lbs with the 2" ball or up to 21,000 lbs with the 2-5/16" ball.

by:

Built like a brick....uh, doghouse! This ball mount is solid!
I bought this to go with our new Ford SD for pulling a low rider motorcycle trailer which has 4" drop axles. The old one was no where near the drop needed. As you can see in the photo, even this one was almost too short. It is just right at the lowest setting.
The only reason I gave 4/5 stars is the safety clips are horizontal to the ground. Being an OCD mechanical engineer, I would prefer them to be perpendicular to reduce the chance of brush and road debris pulling them out.



by:

Simple and easy to switch to another trailer with a different ball size and height. Only negative thing I can say is I would prefer a little tighter fit into the receiver.



by:

This mount is an amazing piece of engineering. My father was a machinist and I know he would be impressed. It functions flawlessly with all of my various trailers, and even looks great on my truck. The order was processed and shipped super fast, arriving within a few days. Great job and hats off to etrailer.com !!!



by:

The weigh safe hitch. Quality made very nice hitch.



by:

Much lighter than my bulletproof just what I need when pulling my utility trailer.



by:

PERFECT. EXACTLY WHAT I WANTED.



by:

Arrived quickly and in perfect shape. Very robust hitch and fits perfectly. Highly recommend this hitch.



by:

Great hitch. Easily adjustable



by:

Makes a little more noise (rattle) than my all steel non adjustable hitch



by:

High quality. Website videos helped with selection decision. Decent price. Fast shipping



by:

Easy to install sturdy towing platform. Like that ths ball mount can be stowed out of the way.



by:

Love it, no more rust. works great looks great
it gave me that extra inch for the Rock Tamers



by:

After 3 months one of the trailer chains bonds against the hitch while taking a shape turn and bent the key to flip the receiver ball. So we are basically stuck with a 2 5/16 receiver since it cannot be opened and flipped. Aluminum is nice but weak at the same time.



by:

Work horse and light weight. Comes with key locks keyed alike for hitch and ball. Stainless steel ball ensures durability for towing long term.



by:

Very solid and beautifully finished. Fits well on my 2016 Ram 2500 4x4, with the newer 2-1/2" receiver, allowing the exact height necessary to level my toy hauler. Ball mount is packaged in foam to ensure it is pristine when it arrives.
Got the locking dual pin for it, as well as the BOLT locks for hitch and coupler, so none of this pretty stuff walks away. Very happy with the whole setup.
A little mixup on the initial order was corrected immediately, so I had all the parts I needed in time to hit the road. Thanks etrailer team!



by:

The 180 Weigh Safe is an excellent adjustable hitch. Exceptional fit and finish.



by:

Been looking for a while on a new hitch and finally pulled the trigger. Etrailer made it fast and easy to get the hitch I wanted at a fair price.



by:

Fast shipping as always! While I haven't had the chance to use this hitch yet, it looks like a high-quality product straight out of the box. I plan to test it this weekend and will update this review if I remember after putting it to use.



by:

Would say WOW ! Excellent communication from the second order was placed , tracking from start to finish. Super packing job and way quick delivery . Product is great , heavy built and easy to change based on what trailer I need to use . Wish I had bought one years ago !



by:

Good product feels very sturdy. My only critique is that it has too much play causing a lot of rattling. The manufacturer should have a tightening bolt so that after installation the two components tighten up and there’s no play.



by:

worked just fine. easy to adjust. will work for both trailers of different hitch height



by:

Hitch works well. Seems it could be a bit tighter when in receiver on truck but overall is a good purchase.



by:

Great price outstanding quality and had it to my front door in less than 48 hours!



by:

This is a solid hitch, the double pin on the ball side locks everything in tight no rattling and love the locking mechanism on this unit… Price is excellent and delivery time wasn’t that long… Great job to you guys at etrailer



by:

Great product. Craftsmanship is top notch.
Easy to use and very sturdy built. My only complaint is the standard coated Balls rusted pretty quickly and look bad. I Should have went with the upgraded stainless steel. Also the salt from 1 winter has left some corrosion on the aluminum of the hitch and the sticker fell off. None of these things affect the function, but i wish it would have stayed looking as nice as it did when it was new.
