Getting a trailer level can make or break the way it tows. This mount’s 3-1/2" drop helps you line up the coupler just right, keeping your trailer even and steady on the road. As long as you’re within an inch or two of level, you’ll be fine—and being slightly higher can even help when tongue weight compresses your suspension. It’s a simple way to keep your setup balanced without the guesswork.
When you’re towing, strength matters more than anything else. This ball mount handles up to 5,000 lbs gross towing weight and 500 lbs tongue weight, making it ready for small campers, boats, and utility trailers. The solid steel construction gives dependable strength every time you hook up.
Nothing’s more frustrating than a ball that loosens over time. This mount solves that with a hitch ball that’s permanently welded to the platform. It can’t loosen or be removed, so you always have a strong, secure connection that also helps prevent theft of the hitch ball.
Road grime and moisture can do a number on towing gear, but this setup holds up well thanks to its rust-resistant finishes. The chrome-plated 1-7/8" ball and black powder coat on the steel shank stand up to corrosion, keeping your gear looking good and working smoothly through countless trips.
Everything you need to get going comes in the box. The mount fits any 2" x 2" trailer hitch receiver and includes the pin and clip so you can secure it right away. Slide it in, lock it down, and you’re ready to tow with confidence.

Today we're going to be taking a look at part number C45151. This is Curt fusion ball mount for 2 inch hitches. It's going to offer a gross towing weight of 5,000 lb with a maximum tongue weight of 500 lb. The ball mount is going to have the permanently attached 1 7/8 inch ball that's going to let you hook up your trailer to your tow vehicle. The shank portion is going to be the portion that slides into the receiver tube of your hitch and then your hitch ball is going to provide a good connection point for your trailer's coupler. The neat thing about the fusion is that the hitch ball is actually welded to the ball mount platform so there's no need to torque it. It's going to be set and ready to go straight out of the box.
You can also see here that we do not have anything hanging below the ball platform so that's a nice smooth, steel surface at this portion right here. The neat think about the fusion is that it's going to prevent theft of the hitch ball. It's also going to eliminate the possibility of your hitch ball being able to loosen up. It's always going to be able to provide a nice, strong and secure towing setup. It's made from a sturdy steel construction. We're going to have a nice black powder coat finish on the actual ball mount with a chrome plated hitch ball. You can see right here that you are going to get a standard 5/8 inch pin and clip.
If you need a hitch pin and lock to lock this to your vehicle that's going to be sold separately. You can find that with part number 7683, but it does come with a hitch pin and clip to get it secured in your hitch. It is designed for 2 inch by 2 inch trailer hitch receivers. It's going to have a nice hollow shank here on the backside. Again, you're going to have a 1 7/8 inch hitch ball. A few measurements that I want to go over with you real quick.
The first one being the distance that we have from the center of the hitch pinhole to the center of the hitch ball. That's going to give us a measurement of about 8 1/8 of an inch. The distance that we have from the center of the hitch pinhole to the back of the shank is going to measure about 2 1/5 inches. This can only be used in the drop position. I measured from the top of the shank to the top of the ball platform.
It's going to give us a drop of 3 1/2 inches. You're going to notice here that on the Curt sticker, they put a 4 inch drop measurement on here. That's an approximate or an estimate or a rounded number, but the exact drop is going to be 3 1/2 inches. Again, that's from the top of the shank to the top of the ball platform. Curt's also going to cover this with a limited lifetime warranty. I'm going to go ahead and show you how it installs inside your hitch. All you have to do is take the shank, slide it into the receiver tube until you get your pinholes to line up with one another and then you simply just insert the included hitch pin and clip. That's going to do it for our review of part number C45151. This is the Curt fusion ball mount for 2 inch hitches with a 5,000 lb gross towing weight capacity. .

Worked perfectly. 310lb tongue weight. 4300 lb boat weight and fuel. Old tongue struggle with the 2inch ball. 1.7/8 was a breeze to snap on
Etrailer had the only 2inch rise 5000lb 1.7/8 ball!!
etrailer carries excellent products at great prices. Customer service is outstanding and they ensure your order makes it to you with no promblems
Great so far
The product is great, ball worked perfectly, towed just fine. Only complaint is how dang long it took to get here.
Fits my needs and works great. Brings ball to the correct height.
This was the right set up for my 2018 4Runner. Works great. As a footnote, I now have a second vehicle for towing (2019 Tundra 4X4). Using the measuring process provided by etrailer folks, I found the same ball works great on the Tundra.
Thanks!
Appears to be very well made, high quality and strong for my small boat towing application!
Both items have worked well to raise my lite weight trailer to a level position for pulling.
I haul a 5.5x10 open trailer w/ a 900 lb. ZTR, a push mower, and a handful of other tools 3 days a week. It is what it is. It does the job, no problem.
A little finish wear and rust on the ball, but nothing major. I LIVE ON A DIRT ROAD, which is probably responsible for the wear.
Hitch was exactly what I expected. I needed a higher ball hitch for my boat and this does the job.
Excellent hitch and Fusion ball mount. There local installer on my hitch did a great job
Exactly as advertised. Fit my hitch receiver perfectly. Excellent order turnaround.
Quick transaction - great quality.
Pretty simple did what it was supposed to
Great product the only downside was it was out of stock when ordered and I was not notified at checkout. They did however have this item delivered within a two weeks so it did not create an issue for me.
Well made hitch. Just the right drop for my Polaris Ranger and trailer.
My experience with etrailer.com was positive all the way around. I received my product before the date that I was given. Once I received the product is was top of the line. I will for sure be ordering from etrailer.com again and again.
Just received the hitch, receiver, and harness. All in excellent condition.
Hitch is now installed.
I'll have to do the harness Saturday, since the lights on my trailer don't work anyway, lol.
Thanks for all your help.
This was a perfect fit for my truck and trailer combo.
