Features to know about
Keeps Your Trailer Level: 3/4" Rise or 2" Drop
A level trailer means no sway, smoother braking, and even tire wear. This Curt ball mount gives you both a 3/4" rise and a 2" drop so your setup stays balanced no matter the trailer. Whether you’re hauling a small utility trailer or a boat, it keeps everything lined up for steady, predictable towing.
Built to Tow with Confidence: 7,500 lbs GTW Capacity
For everyday towing jobs, you need gear that can handle the load without a second thought. This mount’s rated for 7,500 lbs gross towing weight and 750 lbs tongue weight—plenty of strength for most campers, boats, or equipment trailers. The sturdy steel construction and CNC-machined welds hold up under strain so your connection stays secure mile after mile.
Stays Strong and Looks Good: Gloss Black Powder Coat
Towing gear takes a beating from rain, salt, and road debris. The black gloss powder coat on this mount resists corrosion and keeps rust at bay season after season. It’s not just tough—it keeps your setup looking clean and solid even after long hauls or rough conditions.
Simple Setup Every Time: Fixed Design That Just Works
No moving parts or adjustments to fuss with—just a dependable fixed design that slides into your 2" hitch receiver. The 10-1/4" shank length gives plenty of clearance for easy coupling, and the 1" ball hole fits standard hitch balls (sold separately). Once pinned with a 5/8" hitch pin or lock, you’re ready to tow without any drama.

With good information from the website it was easy to order a Curt 2"
Trailer Hitch, the Upgraded Circuit Protected Tail Light Converter Hardwire Kit w/ 4-Pole Connector and Circuit Tester - 119178KIT, Curt Ball Mount for 2" Hitches (3/4" Rise, 2" Drop - 10-1/4" Long - 7,500 lbs - D-4), Curt Pin and Clip Hitch Receiver - C21500, Rubber Tube Cover for 2" Trailer Hitch Receivers - I-728,Review, and 2" hitch ball 40038. Parts were delivered earlier than the initial estimate. Self installation (on a sloped drive way) took just under 2 hour. The fit of parts was very good, instructions and on-line video's were very helpful. My Kia did not have the wire plug in option, but the splice connections in the wire kit were easy to install. Most of the parts are hidden from view when the ball mount is not used.

The extended length hitch came just as "hoped." Thank you. But the example on the web page needs to show a measured distance from the middle of the ball to the pin. I understand this is how hitches are measured. I had to guess. My standard hitch is 8" but I needed 10" for clearance. Luckily I guess correctly.

I purchased this Curt Ball mount 10-1/4" because I also bought ball hitch mounted mud flaps and my existing hitch was too short.This hitch was maybe a little too long, but it should work.I hope this combination will protect my horse trailer from my nasty gravel roads!

Well, a year has gone by and I can say the ball mount hitch has worked as expected. It is longer than I needed and has caused me to rethink how to back and maneuver my horse trailer but I am satisfied with the product. Its a good value.

Very heavy duty and well made, works great!
Didn't realize it didn't have the hitch pin and had to stop and get one locally.
In with the hitches you need to show the ball mount, hitch pin and hitch ball as optional accessories or at least mention in the description these MUST be ordered separately instead of having to dig for them or realize, like I did, all the items I needed weren't there in the middle of the install.

I have a custom made tow guard. The ball mount I have was too short to allow me to attach the tow guard to my new truck. I searched the web and found just what I needed at etrailer.com. It's the only site I found that carried the size I needed. The product fits my needs perfectly. I can now protect my boat from rocks and other road debris when towing. Thank you etrailer.com.

I purchased this unit to extend the trailer jack handle just far enough that I could open the tailgate on my truck with the trailer attached. It worked perfect. I tow a pop-up camper with 2006 Toyota Tacoma. Pricing was good and delivery was quick from etrailer. At first I tried to buy locally from auto parts store or camper store, but neither had in stock anything the right dimensions. The unit from etrailer is made in the USA, fit just right, and was better quality than what I saw locally.

with arthritis in my neck to park my boat. I installed a front trailer hitch on my suv and needed this longer shaft Ball Mount to keep the ball far enough away from my license plate and front bumber that I won't damage my vehicle. The unit fits the bill to a "T" and has already gotten compliments from others for its quality and stability. I look forward to fishing season so I can use it.

I bought this ball mount to replace a shorter unit (8.5"-9") in order for the tailgate to clear the jack on one of my trailers when down. The first one that was delivered had a lot of damage to the powder coat finish due to rough shipping (UPS!). etrailer was very quick to send another out that arrived unscathed. Thanks again!

This is the 10th order I have made from etrailer.com, most of them with multiple items. I cannot say enough about what great experiences I have had with etrailer.com. The website is incredibly helpful, the search tools are great, and the specs, videos and other information are very helpful. The items always ship right away, and arrive well packaged and promptly - and for me they have to cross the border to Canada. I recommend this site to my friends with trailers and I would recommend it to anyone who wants a great experience - and who doesn’t!

or perhaps not really knowing what I wanted, I called and talked to Cathy. She was very helpful and knowledgeable. She checked and guided me to a longer shank which will give me a longer turning radius, as the tongue on my trailer is short and is a problem. The unit is a solid piece of equipment. I had a clevis pin from a 1 1/4" shank and thought I would use that and not order another and she advised me that the pin for a 2" shaft is larger and I needed a new one. She was so good and accommodating I even asked for her boss to commend her for her good work and pleasant personality. Jlw

See what our Experts say about this CURT Trailer Hitch Ball Mount
- Can Volkswagen Touareg Use Weight Distribution When TowingYou will need to check your owners manual to see what the trailer towing capacity is for your Touareg. Many times the construction of a vehicle will restrict the amount of weight the vehicle can tow. I looked at a 2010 Touareg and the trailer hitch we have that is designed for the 2010 is the Curt Trailer Hitch, part # 13220. This is a Class lll hitch and it has a 2 inch receiver opening. A technical note states that you cannot use weight distribution with this hitch. You will want...

We can definitely get your 2023 Ford Maverick set up to tow a Scotty 130 single axle trailer. You will want to start with the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C84BR. This is a bolt on, American made hitch that will be a pretty quick and easy install. The 2" receiver means you will have a lot of options available for accessories down the road as well.

I've looked over the installation instructions, and they seem pretty simple and straightforward. You'll remove some existing appearance panels if they're present, remove the tow hooks from the frame rail, as...
view full answer... - Availability of Curt RockerBall Setup With Longer ShankThe only option that comes from Curt is the # C45WR with the 7-1/2" ball mount length. If you want a longer ball mount you would have to put one together. You could use the Curt RockerBall Shock Absorbing 2" Hitch Ball # C40047 along with something like the # D-4 which is 10-1/4" long. Make sure to measure so you get the right length. Then you will need to attach the Curt Weld-On Sway Control Tab # C45822.
view full answer... - Class III Trailer Hitch Recommendation for 2017 Subaru Outback 3.6RFor a Class III hitch, I'll typically recommend the Curt product because they do a slightly nicer job on their powder coat finish than Draw-Tite does. Curt offers both a traditionally styled Class III hitch, part # C13206 which would have the entire hitch visible from the rear and a mostly-concealed hitch, part # C13410 which would have the crossbar of the hitch concealed behind the bumper with the only visible portion of the hitch being the receiver tube and the safety chain hoops.

It has a 9-1/4" distance from the center of the first hitch pin hole and 10-3/8" to the center of the rear hitch pin hole.

I've linked to the current installation instructions for the Curt # C13143, the correct torque ratings are listed on page 5, step # 13.

view full answer... - Ball Mount Recommendation for Use with a Draw-Tite # 75673 on a 2010 Subaru Outback WagonThere is not a required ball mount for this Draw-Tite Trailer Hitch Receiver, part # 75673. Since you are worried about clearance I would recommend you use a Trailer Hitch Ball Mount, part # D-4. This ball mount has a distance of 10-1/4 inches from the center of the hitch pin hole to the ball hole. You would have plenty of clearance to run this ball mount in the rise position. I attached installation instructions below as well as a review video of this hitch for you to check out.
view full answer... - How to Get a Ball Mount with 0 inches of Rise or DropIn order to get a ball mount that has effectively 0 inches of rise or drop you would need to get a Trailer Hitch Ball Mount, part # D-4, like the one you referenced that has a 2 inch drop, and then use a 2 Inch High Rise Ball, part # C40034. I attached links to FAQ articles on ball mounts and hitch balls below for you to check out also.

I don't have specifics about the departure angle, but as you can see in the photo I provided and the linked installation video, when we installed the # C67JR on a 2021 Outback, the receiver tube butted right up against the underside of the bumper fascia. If you measure down 3 inches from the underside of your bumper fascia, that will be the lowest point...

- Trailer Hitch Fits Recommended for 2013 Subaru CrosstrekWe do indeed offer hitch fit options for the 2013 Subaru Crosstrek. If your Crosstrek is equipped with the knock-out panel in the rear bumper panel, and you'd like a partially concealed hitch that mounts behind the bumper with only the receiver tube and safety chain loops being visible, I'd recommend the EcoHitch # 306-X7203. This hitch only works on Crosstrek models with the bumper knock-out panel. If you'd like a standard, fully visible hitch, I'd recommend the etrailer brand Class...

- Factors to Consider When Picking Out Length of Ball MountI would say the shorter you can go without any turning clearance issues will be the safest and best option. The length of the ball mount doesn't typically play a huge factor in ride quality or anything but we have longer ball mounts for trailers that are wider at the nose of the trailer to help get a little more clearance for turning. In theory a longer ball mount would put more leverage on the hitch in terms of tongue weight but most of the time it's not something that's really noticed...
view full answer... - Trailer Wiring Harness for 2002 Toyota HighlanderThe Plug-N-Tow wiring harness you mentioned, part # 33425 is indeed the correct harness for your 2002 Highlander. The harness is pretty easy to install, using existing connectors located behind the tail light assemblies with an additional wire that is ran to the positive battery terminal. Assuming that you already have a drawbar like part # D-4, Hitch Pin and Clip, # PC3, for a 2 inch receiver or # 36051 for a 1-1/4 inch receiver and the appropriate trailer ball for your trailer, you...
view full answer... - Will There Be Play Between the Ball Mount Shaft and the HitchThere will be a small amount of play between the shank of the ball mount and the receiver hitch when the ball mount is installed. If you would like to eliminate this play you can use an anti-rattle device like an Anti-Rattle Device for 2 inch Hitches # SR25219. I attached a review video for this product for you to check out also. I attached an FAQ on ball mounts that you might find informative also.

The appearance and design of the two hitches are pretty similar. As far as quality goes, both brands are about equal. Given this, there's no reason why you couldn't go with the less expensive Curt model. If you were planning on towing with your Tacoma, you might also need the following: Trailer wiring harness, part # 118496 Ball mount, part # D-4 Hitch Pin and Clip,...
view full answer... - Short Ball Mount Recommendation for a 2013 Volkswagen TouaregHaving a ball mount that is longer should not be an issue. It actually can provide more clearance when turning. The standard for a 2 inch ball mount is around 8 to 8-1/2 inches from the center of the hitch pin hole to the center of the ball hole. We currently offer several aluminum ball mounts for 2 inch hitches that have a 2 inch drop. Curt, # C74WR Brophy, # EA20 Fulton # F97CR

Alternatively it could be the receiver side as well but it seems odd that the Brophy Ball Mount for 2" Hitch - 3/4" Rise, 2" Drop - 13-1/4" Long - 10,000 lbs # BH20 fits if it were the receiver side. The # BH20 will work fine for your 7,500 lb capacity if you don't want to purchase another option. You can also...

view full answer... - Is it Okay for Ball Mount to Move in Trailer Hitch Receiver SomeWhat you are describing is actually pretty normal for a ball mount. There is almost always some tolerance between the trailer hitch receiver and the ball mount (or accessory) being installed which is why there are a variety of anti-rattle devices out there. Some accessories and ball mounts come with them built-in but if you have a standard ball mount there are aftermarket anti-rattle devices you can use.

Spare tires larger than the factory size are not tested with trailer hitches so if your spare is larger than OEM it could prove to be a problem.

I recommend using Loctite Blue Stick Threadlocker, part # LT37643, which you apply to the threads of the bolts. You want to make sure to use a torque wrench and torque down all bolts as specified in the instructions. With a few basic tools you will be able to install the hitch in your driveway.
