Video Transcript for Checking Out the Curt Alumalite Aluminum Adjustable 2-Ball Mount

Hi everybody, Andy here with etrailer.com. Let's take a brief look together at this CURT AlumaLite aluminum adjustable two ball mount for your two inch trailer hitch receiver. This adjustable ball mount is going to slide into your two inch hitch receiver on your vehicle and give you a maximum towing capacity of 12,500 pounds and a maximum drop of 5 1/2 inches. Now this adjustable height is going to let you tow trailers of different heights with the same vehicle. You're just going to slide this ball platform up or down along this shank and then secure it with the included pins and vibration resistant clips that you see here. You have seven adjustment holes that are available here that are gonna give you, again, that maximum drop of about 5 1/2 inches.

And this is going to adjust in one inch increments. That's the measurement between each of the holes on center. This is not intended for use in the rise position, only in the drop position. You have two different size polished steel hitch balls that are gonna let you tow the trailers with different coupler sizes. You can tow up to 12,500 pounds with a 2 5/16 inch ball, or 8,000 pounds with a two inch ball.

And in regards to the tongue weight, with the 2 5/16 inch hitch ball, the tongue weight is going to be 1,250 pounds, and with the two inch ball, it's going to be 800 pounds. To switch the balls, you're simply going to remove the pins and clip and rotate the ball and then slide it back up the channel. Let me give you a brief demonstration of that. So I'm just gonna go ahead and remove the clip here. There we go.

And then turn this around, try to keep it balanced on my blocks here, and remove the pin. Okay, and then I just wanted to show you that this is going to be able to slide easily up and down. And then to rotate the ball, you're just going to remove the platform, rotate it, and then just slide it back into place just like that. So it slides very easily. Obviously I'm precariously set up here on these blocks, but let me see if I can line my holes up here again and slide this back into place.

I'm just gonna choose that right there. And then I'm gonna slide my clip into place here. Take one of these blocks back. And then just slide the clip into place here with the pin. And then it's going to be just as simple as that. So we're back into place using our two inch ball, and we're gonna be good to go. So really pretty easy to get this adjusted right where you need it. And it's a really great, great designed shank setup here. This is lightweight billet aluminum construction. So it's lightweight, but it's gonna be very durable. It's corrosion resistant. And in case you we inchesre wondering, I did take some measurements that might prove helpful to you. So measuring from the center of the hitch ball to our first hitch pin hole, it's gonna be about 7 7/8 inches on center. And then again from the center of our hitch ball to the second hitch pin hole, about 9 1/8 inches on center. And then from the center of the second hitch pin hole to the end of the shank, about 1 5/8 inches. I wanted to point out too, as you probably saw, the end of our shank is angled. So I like that because that's going to make this all the more easier to slide that into your trailer hitch receiver. The hitch pin hole diameter is 5/8 of an inch, so you will get the pin and clip for the hitch, but this is really an investment that you're making. So I would recommend taking a look at our hitch lock options that we have here at etrailer.com. We do have several, and we do even have an option where you can buy a lock for the shank and then a lock for the ball platform. So we do have those options available here at etrailer.com. Check those out so you have a way to protect the investment that you are making with this ball mount. This does have a limited lifetime warranty from CURT. And I think that's gonna wrap up our real quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
