Features to know about

Keeps Your Trailer Level: 2" Drop for a Straight, Stable Tow

When your trailer sits even with your vehicle, everything just feels smoother—less sway, better tracking, and balanced tire wear. This Curt Fusion Ball Mount gives you a true 2" drop so your trailer stays level and steady on the road. It fits a standard 2" x 2" hitch receiver and measures 7-1/2" from the center of the hitch pin hole to the center of the ball, giving you plenty of clearance while keeping your setup tight and secure.

Built to Stay Solid: Welded 1-7/8" Ball That Won’t Loosen or Get Stolen

No need to worry about torquing or tightening hardware again. The 1-7/8" chrome-plated hitch ball is permanently welded to the mount, creating one solid piece that can’t loosen up over time or disappear from your receiver. The welded design also means fewer parts to maintain and a stronger connection from vehicle to trailer every time you hook up.

Dependable Strength for Everyday Hauling: 5,000 lbs GTW and 500 lbs Tongue Weight

Whether it’s a small boat, utility trailer, or light camper, this mount handles up to 5,000 lbs gross towing weight and 500 lbs tongue weight with confidence. The sturdy steel shank takes the stress of regular towing without flexing or rattling. It’s made for drivers who just want reliable strength without overcomplicating their setup.

Made to Last: Rust-Resistant Finishes That Hold Up Season After Season

Road salt and weather can take a toll on towing gear, but this mount fights back with protective coatings where it matters most. The ball mount has a black powder coat finish that resists chips and corrosion, while the hitch ball itself is chrome plated for long-term shine and durability. It’s a simple combo that stays looking good and working right after countless trips.

Ready to Tow Right Away: Pin and Clip Included

Getting on the road is straightforward—just slide the shank into your 2" receiver, secure it with the included pin and clip, and you’re set. There’s no guesswork or extra hardware needed. Everything you need for a solid connection is right in the box so you can hook up quickly and get moving.

Great parts and customer service.

well made, easy installation, was what i was looking for.



by:

Exactly as described, well packed, fast shipping, and really the best selection out there. Usually when you buy something like this online it shows up destroyed. An incredible value.



by:

It is a solid piece of work, all right. Dropped right into place and should do the work nicely. We ordered two-day delivery; but it didn't arrive in two days. IT ARRIVED THE NEXT DAY! Supurb service from etrailer. Thanks. -PF_

Great product. Fits perfectly. The installation video was very helpful.

High quality hitch



by:

Spoke with Alex and within 5 minutes we were able to identify the products I needed. He also helped us with our sales tax exempt certificate to apply to the order. The products shipped the same day I called.



by:

I could not be happier with this ball and hitch. I highly recommend the ball and hitch and so easy to install.



by:

I purchased this trailer hitch for pulling a small trailer for a kayak. Great product, fast delivery, easy install. The bristle brush would have been helpful since I had one stubborn bolt. Wd40 took care of it. I just slid under my car and installed solo, which was challenging but doable. 139lbs of torque took some strength. Overall I was impressed with the delivery and packing. I received the trailer hitch in a box where it was fastened with other cardboard and staples. Not one ding. I ordered this same product from [online retailer] and it came to me like it was thrown down a stair case. [online retailer] delivers the hitch without a box and just had bubble wrap on the receiver end. Overall great price and I would definitely recommend this company. I also purchased the wiring harness for the trailer light and the trailer hitch ball mount. Both products were also neatly boxed with the trailer hitch. Two thumbs up.



by:

Have purchased trailer hitches, ball mounts, & trailer light wiring harnesses for two different vehicles from etrailer. Have been very satisfied with all purchases. Thanks



by:

Didn't realize the ball was permanently attached to the hitch, as I bought this with the intention of flipping it and using it as a rise hitch. 2" drop too low for my application. Not really worth the hassle of returning, and I guess the fault lies with me.

This ball mount features a permanently welded hitch ball that cannot be stolen or loosened. 1-78 Diameter hitch ball is chrome plated. Pin and clip included. Ball mount can be used in the position only.



by:

Very well made. Very heavy. Arrived 2 days early which was great. Pricessed and packed first day ordered. Shipped the next.



by:

Hitch ball works flawlessly with my trailer. Fits our hitch receiver just fine. Has the typical subpar black paint finish that chips easy though. Otherwise I would give it 5 stars.

Traded in our old tow vehicle and got a newer model. I installed a new receiver hitch on this vehicle. This hitch fits the hitch receiver, but its a bit sloppy. You get a lot clunking noises when towing the trailer. The paint has held up fine and the tow ball still looks new.



by:

I am very happy with my trailer hitch receiver from etrailer. I installed one on my 2011 Toyota rav4 for towing a small teardrop trailer I made during the pandemic. I also purchased a wiring harness to power the trailer lights from etrailer and after some doing have it working well. The cost of doing it myself was a small fraction of having the dealership do the work. The hitch receiver is easy to install as there are pre drilled holes to receive bolts in the frame. The wiring is a bit more complicated but I did it. God bless online videos. I'm happy with the results.



by:

Appears to be very well made, high quality and strong for my small boat towing application!



by:

Exactly as advertised. Fit my hitch receiver perfectly. Excellent order turnaround.

See what our Experts say about this CURT Trailer Hitch Ball Mount

  • Best Way to Transport 2 Trikes on My Vehicle
    The best and only option we have for transporting two trikes is using a utility trailer like the # K2MMT4X6 (6 feet long) or # K2MMT5X7 (7-1/2 feet long). For attachment straps to secure your bikes, I recommend ratchet straps like the Erickson Re-Tractable Ratchet Straps w/ Push Button Releases # 34414. If you decide to go the route with the utility trailer, you need to have a 4-way wiring harness and a ball mount/ball like the ones included in the Curt Fusion Ball Mount for 2" Hitches...

  • Is There a 1-7/8 Inch Hitch Ball with a 5,000 Weight Capacity
    The majority of standard hitch balls with a 1-7/8" diameter will have a 2,000-3,500 lb weight capacity. If you need a hitch ball with a 1-7/8" diameter that has a 5,000 lb weight capacity then you will need to use a pintle hitch ball. For this, we have part # C48810 which has a 1-1/4" diameter shank. You will need to measure the hole for the hitch ball on your ball mount in order to make sure this one will work for you. The only difference between a standard hitch ball and a pintle hitch...

  • Is There a Shorter Shank Option for Curt Fixed Ball Mount with 2 Inch Drop
    The Curt Class III Ball Mount with 2" Ball - 2" Drop - 7,500 lbs # C45036 does come with the hitch ball installed. The ball platform is 3/4 inches thick which is standard with a 1 inch diameter hole. This is the shortest option for that rise and drop. There is a lower rated option in # C45131 but it is only due to the smaller hitch ball that is 1-7/8 inch diameter. It still uses the same ball mount and just changes the hitch ball. There are longer options that are similar but nothing...

  • What do You Recommend for Transporting My 88-Pound E-Bike on a 2018 Subaru Outback?
    If you are looking for a way to transport your 88-pound Ariel Rider Grizzly, we do not have a standard bike rack that can accommodate that weight. However, the best and easiest route is to use a dirt bike/moped carrier like the Ultra-Fab Dirt Bike Carrier for 2" Hitches - With Ramp # UF48-979033. This carrier comes with an inside track width of 5 inches wide, so it is plenty of room for your 4-inch wide tires. It also comes with an included ramp to make loading a piece of cake.

  • Hitch Equipment For 2020 Chrysler Pacifica Hybrid
    It looks like your towing capacity is around 3600 pounds, although you should consult your vehicle's documentation for exact capacity. A 1200 pound boat and trailer should not be a problem. For your hybrid the etrailer e98903 would be a good choice for a Class-3 hitch with 2" receiver. I have attached a link to this product and an installation video on a 2020 Pacifica. I think the matte black finish hides the hitch better and will inhibit rust longer. You will also need a ball mount...
