Features to know about
Keeps Your Trailer Level: 3" Rise or 4" Drop
A level trailer is key to handling well and braking evenly. This solid ball mount gives you both a 3" rise and a 4" drop so you can match your trailer height for stable towing. It fits a 2" x 2" trailer hitch receiver, keeping your setup balanced whether you’re towing small utility trailers or heavier loads.
Built for Heavy-Duty Hauling: 12,000 lbs GTW Capacity
When you’re hauling serious weight, you need gear that’s up to the task. The solid steel shank on this mount is rated for a 12,000 lbs gross towing weight and 1,200 lbs tongue weight, giving you the strength and confidence to move heavy trailers without flex or wobble.
Durable Finish That Holds Up: Corrosion-Resistant Black Powder Coat
Towing gear takes a beating from rain, road salt, and grime. The high-gloss black powder coat on the steel shank resists corrosion and keeps it looking sharp season after season. It’s a straightforward design that stays strong through years of use.
Simple, No-Fuss Setup: Fixed Ball Mount That Just Works
No moving parts, no complicated adjustments—just solid steel that slides right into your hitch receiver. With a 10" length from the center of the hitch pin hole to the center of the ball hole and a 5/8" pin hole diameter, it’s easy to install and ready to tow once you add your preferred hitch ball and pin or lock (each sold separately).

Don't see the needed to make it from solid steel.. heavy, seems wasteful. Wish I would have gotten the hollow one with chromed balls, same load capacity. Can't imagine the powder coat holding up long.

Sooooooo - what do you think? Are we doing OK? I think so. You should come join us. On Friday we are leaving for the Texas Big Bend region.
I do have ONE NEED! But I don't think you can help me. I need a padded zipper-case to put the hitch in when I remove it from the JEEP. I never leave the hitch in when off-roading. But the one I am using is long!

Literally a solid hitch, not just hollow tubing. I use to tow my boat and is rated more than I need but why cut it close! This hitch also has enough room for my Rock Tamers to be used.

Wow. Heavy duty. This is literally a single solid piece. No fasteners. No welds. May exceed your vehicle's tongue weight (just kidding). This takes care of both of my trailers' tendency to sit a little "nose low".

Received everything I ordered within just a few days of placing order. etrailer was great about informing me of a product they were currently out of, but supplied a date that the products should received. I was surprised to find out that my order was filled and shipped in a couple of days after hearing of the back order. Will refer etrailer to friends for quality products and service!

Nice heavy duty hitch. Works well with truck and dump trailer. Long 10 inches from ball to pin hole tailgate comes down and doesn't hit trailer jack

We always call etrailer, first, whenever we need anything for our Motor home or our trailer. They are so knowledgeable and supportive, it takes all the worry out of ordering wrong. They even helped us with ordering Thule carrier and cross bars!

See what our Experts say about this CURT Trailer Hitch Ball Mount
- Recommended Ball Mount and Hitch Ball Compatible with Tightening Tool 45007The Curt Hitch Ball Holder and Tightening Tool for Ball Mounts # C45007 will work well with the Curt Solid Ball Mount for 2" Hitches # C45313. The platform is the standard 2-1/2 inches wide. I recommend the hitch ball # A-90 for a 2 inch ball or # 19286 for a 2-5/16 inch option. You may also want to consider # e98880 for a locking hitch pin to secure your investment and deter theft.

- Selecting The Correct Trailer Hitch Ball Mount For a 2020 Honda CR-VHonda list the ground clearance of the 2020 Honda CR-V all wheel drive trims at 8.2" and the front wheel drive trims at 7.8". It is really hard to recommend a ball mount rise height without knowing the coupler height for the trailer. It is important to remember when calculating rise or drop this is done based on the measurement to the inside top of the receiver. This should be around 13-1/2" based for an AWD CR-V with the Draw-Tite Receiver # 76128 we installed it on in our shop. I like...
view full answer... - Recommended Trailer Hitch And Wiring To Tow A Trailer With A 2022 VW Atlas We definitely have what you need to get your 2022 Volkswagen Atlas all set up to tow a small trailer. There will be a couple more things needed than just a hitch and wiring, but not many. With that said, let's get into it. First thing's first, the hitch. For this we have the American made Curt # C24ER. There is some fascia trimming required for the installation, but no drilling, so it is a pretty straight forward install. This is also rated up to 6,000 pounds towing and 900 pounds of tongue...
view full answer... - Availability of Ball Mount With 3 Rise/DropI'm not 100% sure what you need here but I will assume you're looking for a ball mount for a 2" hitch that either has a 3" rise or a 3" drop. If you need a 3" drop we have the Curt RockerBall Anti-Rattle Towing Kit # C63KR which has a 3" drop exactly or the TowSmart # TS64FR with a 3-1/4" drop which won't be an issue. If you're looking for a 3" rise you can use the Curt # C45313. This doesn't come with a ball so you can use the # A-90 for a 2" ball or # 19286 for a 2-5/16" ball.
view full answer... - Ways to Carry a Bike Rack While Towing a TrailerWe do have a couple options available to accomplish what you need to do, but the Convert-A-Ball Adjustable-Height Ball Mount - 2" Hitch - 9" Rise to 10-1/4" Drop # TK5007 cannot be used as a vertical receiver. With that being said, one way to carry a bike rack while towing a trailer will be to add a hitch to the front of your 2019 Ridgeline. The Draw-Tite # 65073 will give you a standard 2 inch receiver and allow you to attach a rack to. However, with bikes on the front of a vehicle it...
view full answer... - Recommended 3 Inch Rise Ball Mount for 2 Inch Trailer Hitch Receiver The closest option we have available to the Curt Drawbar # C45520 you referenced that is designed for 2 inch hitch receivers is the Curt Solid Ball Mount # C45313. This is a really nice ball mount that features the same 3 inch rise but can also be used in the drop position for a 4 inch drop. It has a towing capacity of 12,000 pounds. It measures 10 inches from the center of the hitch pin hole to the center of the ball hole. I have attached a short video demonstration on this product that...

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... - Shock Absorbing Hitch Ball with 1-1/4 Shank and 2-5/16 Ball for 2 Ball MountsIf the trailer requires a 2-5/16 ball, you don't want to use the 2" ball to pull the trailer. The 2-5/16 ball has a larger shank so it is not interchangeable with the Curt RockerBall Anti-Rattle Towing Kit - 2" Ball - 8-1/4" Long Mount - 7,500 lbs Item # C63KR I recommend Curt RockerBall Shock Absorbing 2-5/16" Hitch Ball - 1-1/4" Diameter Shank - Chrome - 12K Item # C29FR and Curt Solid Ball Mount for 2" Hitches - 3" Rise, 4" Drop - 10" Long - 12K Item # C45313. It will give you the extra...
view full answer... - What is the Distance From the Center of the Pin Hole to the Center of the SHank Hole The Curt Solid Ball Mount for 2" Hitches part # C45313 does have a distance of 10" from the center of the hitch pin hole to the center of the ball shank hole. Check out the linked video to see my buddy Cole verify this.
view full answer... - Ball Mount Kit For The EcoHitch On A 2019 Subaru Outback WagonYou're correct on the measuring of which ball mount you would need. With the top of the hitch to the ground being 15 inches and the coupler height of the trailer being 18 you would need a ball mount with a 3 inch rise. The Curt Solid Ball Mount for 2 inch Hitches # C45313 has a 3 inch rise and has a gross towing weight up to 12,000 pounds. The 2 inch hitch ball # A-90 and Pin and Clip # C21500 are needed as well. I attached a review video link below.
view full answer... - Recommended Inverted/Flipped Hitch Ball for a 2020 Volkswagen AtlasThe 2020 Volkswagen Atlas has a low hitch receiver height therefore you'll likely need a ball mount with built-in rise to tow most trailers level. In order to find the correct one simply measure from the ground to the bottom of the coupler on the trailer while level and then subtract the distance from the ground to the top inside edge of the trailer hitch on the vehicle. You're likely looking around 3" and in which case I recommend the Curt Solid Ball Mount for 2" Hitches part # C45313...

I do have a bag that we carry that would be great for carrying a ball mount. It is part # ETBMB that measures as 16 and a quarter inches long by 5 and a quarter inches high and 4 inches wide.
