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.

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.

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.

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.

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.

See what our Experts say about this CURT Trailer Hitch Ball Mount
- Best Way to Transport 2 Trikes on My VehicleThe 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...
view full answer... - Is There a 1-7/8 Inch Hitch Ball with a 5,000 Weight CapacityThe 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...

- Hitch Mounted Cargo Carrier With Ramp To Carry A Lawnmower And TrimmersI do have a couple of options that will work great for you. The first option that I recommend, is going with the: -Flint Hill Goods 30" x 50" Wheelchair Carrier w/ 48" Ramp # FHG77ZR. This is a hitch mounted cargo carrier that will slide into your 2" trailer hitch, and provide you will a 38" x 50" cargo space with a ramp so you can load your lawn mower and your trimmers. This cargo carrier has a maximum carrying capacity of 500lbs, and includes 6 built in eye hooks for tie down points. For...

- Origin Of Curt Fusion Ball MountThe Curt Fusion Ball Mount for 2 inch Hitches - 1-7/8 inch Ball - 2 inch Drop - 5,000 pounds # C45131 is made in china. most hitch balls and pins are made in China. The Curt Ball Mount for 2 inch Hitches - 1 inch Rise, 2-1/4 inch Drop - 7-5/8 inch Long - 7,500 pounds # C45030 is made in the USA but it's only the ball mount.

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.

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...
view full answer... - Is There A Curt Fusion Ball Mount Available With a 2-5/16" Hitch Ball? I do have an option for you as the Curt Fusion only offers ball mounts with a 2" Ball # C45134 or 1-7/8" hitch ball # C45131. The Curt Solid 2-Ball Mount # C45002 is a straight shank design with a 2" and 2-5/16" hitch ball welded in place like the Curt Fusion.

view full answer... - Hitch Equipment For 2020 Chrysler Pacifica HybridIt 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...

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.
