Video Transcript for Curt Ball Mounts - Fixed Ball Mount - C45311 Review

Today we're going to be taking a look at the Curt ball mount for 2" hitches. This is a heavy duty ball mount that let's you hook up your trailer to your tow vehicle. The shank of the unit, which is this part right here, this slides into the receiver tube of your hitch. The ball platform provides a mounting point for your hitch ball. Hitch balls are sold separately. If you're in need of one, we carry a lot of them here, at etrailer.com, and I'm sure you can find what you're looking for. You can use this in both the drop or rise positions.

This position, here, would be your drop. This position, here, would be your rise. Both positions are available to help ensure level towing for your application. It's made from a sturdy steel construction. It's going to feature a corrosion resistant, high-gloss, black powder coated finish. If we look on the backside, you'll notice that it does feature a hollow shank. Now, when you're installing this inside your hitch, you will need to secure it using a hitch pin and clip, or a hitch lock.

Those items are sold separately. If you're in need, you can find them here, at etrailer.com. These pin holes on the mount will accept a standard 5/8" diameter pin. The product's made right here in the USA. It is designed for a 2" x 2" trailer hitch receiver. It's going to offer a gross towing weight of 10,000 lbs.

Maximum tongue weight for this unit is 1,000 lbs. A few measurements I want to go over with you real quick. We're going to take a measurement from the center of the ball hole to the center of the hitch pin hole. If we put a ruler on here and do that measurement, we can see that that's going to measure about 9 3/8". Again, that's measuring from the center of the hitch pin hole to the center of the hitch ball hole, 9 3/8". Now, if you're using this in the rise position, which would be this position here, it's going to give you a rise of about 2 3/4". A rise measurement is taken from the inside top edge of the receiver tube of your hitch, up to the top of the ball platform.

If you're using the unit in the drop position, it's going to give you a maximum drop of about 4" doing those same measurements, so from the inside edge, top edge of the receiver tube of your hitch, to the top of the ball platform, so 2 3/4" rise with a 4" drop. The ball hole diameter on this unit, is the diameter of this hole right here. That's an inch and a quarter. The drawbar thickness, or platform thickness, 3/4". Then the drawbar width is 2 1/2". The product's covered with a limited lifetime warranty. That's going to do it for today's look at the Curt ball mount for 2" hitches.

Good quality. To note: I have a 1inch lift on my 1500 and the ball point is lower than ideal. Best suited for trucks with a 3 inch lift or more. 597722

  • How to Determine Ball Mount Rise or Drop for 2018 Ford Edge
