Features to know about
Keeps Your Trailer Level: 4" Drop or 2" Rise
A level trailer tows smoother and tracks straighter down the road. This ball mount gives you a 4" drop or can be flipped for a 2" rise, so your trailer sits just right behind the tow vehicle. That means less sway, even weight distribution, and a steadier feel whether you’re hauling gear for work or heading out for the weekend.
Built for Dependable Towing: Rated for 3,500 lbs GTW
When you’re towing smaller to mid-size trailers, reliability matters. This mount has a gross towing weight rating of 3,500 lbs and a tongue weight of 350 lbs. The steel construction takes the strain without flexing, so it’s solid for your everyday hauls. It’s the kind of simple, strong hardware you can count on every time you hook up.
Resists Rust and Road Grime: Chrome and Powder Coat Protection
Towing gear gets hit with rain, salt, and dirt constantly. The chrome-plated 1-7/8" ball fights corrosion while the black powder coat on the steel shank keeps rust at bay. Together they hold up against weather and road wear so your setup stays looking good and working smooth.
Everything You Need in One Kit: Pre-Torqued Ball with Pin and Clip
This kit comes ready to tow with the ball already torqued to factory specs, plus a pin and clip to secure it in your 2" receiver. No extra tools or guessing required—slide it in, lock it down, and you’re ready to go. It’s straightforward gear that saves time every time you hitch up.

The Curt trailer hitch and wiring harness for my 2016 Highlander was a perfect fit. Installation was a breeze just following the etrailer videos. I opted for the 4" drop ball mount because of the Highlanders ground clearance but the standard 2" drop would have been just fine. Will use etrailer again without hesitation.

I purchased this hitch to pull my utility trailer with. It was easy to order, arrived on time, and simple to install/use. This hitch is built very well and strong, and has a good coating finish on it. Great product!

Good service, good parts. I'm having a problem with a part that I ordered from another vendor and now wish I hadn't. But Mike and I have been emailing back and forth to try to resolve the issue, EVEN THOUGH I didn't buy the part from etrailer !!!! You certainly can't beat that kind of service. I've even emailed the manufacturer, but have heard nothing in a week. Etrailer is the best. THANK YOU etrailer

The length of this hitch is great. I can finally open the tailgate of my truck when the trailer is hooked up even if it only clears the tailgate by about 1/2 inch. I couldn't find another hitch long enough to allow that

Glad we could help, Chris! It's definitely nice being able to open the tailgate when a trailer is hooked up. We get that complaint quite often. What kind of trailer are you towing? Looks like a utility trailer.

The Curt ball mount with the 10" drop is a perfect fit for my motorcycle trailer. The extended length really helps in tight turns. Best of all, it's made in USA. Stay safe on those Ozark streams
here's a couple more photos of the Curry ball mount. It provides just enough clearance to allow me to make sharp turns without making contact with the rear spare tire

See what our Experts say about this CURT Trailer Hitch Ball Mount
- Is 1-7/8" Hitch Ball Available to Fit Curt 2-1/2" Weight Distribution ShankHey Tony, thanks for reaching out! There aren't any 1-7/8" hitch balls that will fit the Curt Weight Distribution Shank # C17131 you're already using, but I do have a way you can tow your pig cooker by using the Curt Class III Ball Mount # C45055 along with the etrailer Magnetic Hitch Receiver Reducer Sleeve # e28JR. I know it's not exactly what you were hoping for, but the only alternative would be to purchase one of the adjustable tri-ball mounts that are a bit more costly than this setup.
view full answer... - What Drop Ball Mount is Needed for Hitch 22 inches from Ground and Coupler 16 inches From GroundThanks for getting me the coupler and hitch height of your setup. Based on that you'd need a 6 inch drop ball mount. So for a 2 inch ball mount that has the correct amount of drop you'd want the # C45064 which comes with a 2 inch hitch ball installed as well as a hitch pin and clip.
view full answer... - Flipping The Curt Curt Class III Ball Mount Upside Down For A 2" Rise Yes you will be able to flip the # C45055 upside down and also flip the hitch ball around to create a 2" rise.
view full answer... - Recommended Ball Mount with 1-7/8 Inch Diameter Hitch Ball for 2 Inch Trailer Hitch ReceiverThe 2018 Toyota 4Runner comes with a 2 inch hitch receiver that is commonly referred to as a Class III hitch. There are ball mounts that will allow for a 1-7/8 inch hitch ball that will fit your trailer hitch receiver. For the most adjustable option, I recommend the B&W Tow & Stow 3-Ball Mount # BWTS10048B which will give you the 3 standard hitch ball sizes and give you the ability to adjust vertically for your trailer coupler height to tow level. It also has a nice stowable feature...
view full answer... - Hitch for Small TruckI have several hitches that closely match what you are looking for. Hitches I have that fit a 2"X2" receiver opening, and with 4" drop are as follows. Curt # C45055, 8-1/4" hitch pin center to ball mount center. Overall length is 12-1/2" Curt # C93KR, 8-1/4" hitch pin center to ball mount center. Draw-Tite # 40331, 9-3/4" from hitch pin center to ball mount center Curt # C45313, 10" from hitch pin center to ball mount center Draw-Tite # 4285, 12" hitch pin center to ball mount center....
view full answer... - How Much Rise Would Curt Ball Mount # C45055 HaveThe Curt ball mount # C45055 comes with a ball in the drop position, but if you were to remove the ball and flip it over to the rise position it would have a 2 inch rise.

The Curt Trailer Hitch and Vehicle Wiring Kit have worked just fine. Thanks to the etrailer videos, the installation was easy. I have recommended etrailer to several friends contemplating after market hitches.
