Features to know about
Keeps Your Trailer Level: 1" Rise or 2" Drop
A level trailer tows straighter, brakes more evenly, and just feels better on the road. This solid ball mount gives you both a 1" rise and a 2" drop so you can line up your trailer height exactly where it needs to be. It measures 10" from the center of the hitch pin hole to the center of the ball hole, giving you plenty of reach for a balanced setup.
Built for Heavy Loads: 12,000 lbs GTW Capacity
When you’re pulling serious weight, you want gear that doesn’t flinch. With a gross towing weight rating of 12,000 lbs and a tongue weight rating of 1,200 lbs, this ball mount is made for heavy-duty hauling. The solid steel shank translates every bit of your truck’s power into dependable strength without flexing or wobble.
Simple, Reliable Design: Fixed Mount That Just Works
No moving parts to adjust or maintain—just a solid connection that stays true every time you hook up. The fixed design keeps the ball platform steady in either drop or rise position, so you get predictable towing performance with less fuss. It’s straightforward gear that does its job without needing attention.
Fights Rust and Road Grime: High-Gloss Black Powder Coat
Towing gear takes a beating from weather and road debris. The corrosion-resistant, high-gloss black powder coat finish shields the steel from rust and wear so your mount stays looking clean and lasts trip after trip. It’s built to handle rain, salt, and grime without losing its shine.

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.

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!
Thank You!!!!

I just went through the purchase process looking for a very specific hitch that I could not find anywhere else on my own. So I called e trailer and spoke with Preston there, and it took some time and diligence, but he found exactly what I needed (a hitch for that would fit a specific farm implement to tow behind a truck), and had it to my door within a couple of days! The service was great and I appreciate the fact that he took the extra time to research and narrow down the right choice for me. Thank you!

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.

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".

This thing is very solid and heavy duty; it weighs in at 16.8 pounds. I haven't pulled with it yet, but I believe it's exactly what I needed to pull the two trailers I need to pull (2" ball, and 2 5/16" ball).

See what our Experts say about this CURT Trailer Hitch Ball Mount
- Ball Mount for Curt RockerBall on 2012 Toyota TundraHi Raymond; I understand you need a ball mount like the # C45312 so you can install your Curt RockerBall # C29FR. Do you also need a trailer hitch like the # C15398 for your Tundra? Since you said you need a hitch, and a receiver, I'm just trying to clarify. If you have a hitch on your truck it probably has a 2" receiver on it that the ball mount will fit. I do know these terms get used interchangeably a lot so it can be a bit confusing. Assuming you have a hitch already on the Tundra...
view full answer... - Availability of Just Ball Mount of Curt Ball Mount # C45036Yes, for just the ball mount portion of the part # C45036 you'd want the part # C45312 instead. This doesn't come with the pin and clip # C21504. If you want the smaller 1-7/8 inch ball kit use # C45034 or # C45041 for the 2-5/16 inch.

You will need the 2" Hitch Ball # CB26C and Gen-Y Hitch Pin and Clip # 325-GH-096 to have all the parts made in the USA.

Both ball mounts feature a 2 inch drop or a 1 inch rise if inverted. The B&W has a 16K capacity, with the Curt model having a 12K capacity. Both are designed for trailer balls with a 1-1/4 inch diameter shaft.

There is a really good option from Curt that is extended and will work perfectly for you: - Curt Solid Ball Mount for 2" Hitches - 1" Rise, 2" Drop - 10" Long # C45312 This ball mount measures 10 inches from the center of the hitch pin hole to the center of the ball hole so it will give you the clearance you need.

view full answer... - What Diameter Ball Hole Does Curt Ball Mount # C49FR Fit You wouldn't most likely. The ball hole you'd need to have in your ball mount to use the hitch ball # C49FR would need to be 1-1/4 inch. There might be some slightly variance but this dimension is pretty standard. The hitch ball # C45312 is an example of a ball mount that fits this.

The ball mount has a sturdy steel construction with a solid shank. It has a black powder coat finish that covers an e-coat base which offers superior rust protection. The 2 inch hitch ball # 19258 and the 1-7/8 inch hitch ball # 19256 will work with the shank above. To lock the drawbar to your trailer hitch The etrailer Trailer Hitch Receiver Lock for 1-1/4" Hitches # e98879 will help prevent theft of the ball mount...

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.
