Video Transcript for The Low-Down on the Curt Fusion Ball Mount for 2" Hitches

Today we're going to be taking a look at part number C45151. This is Curt fusion ball mount for 2 inch hitches. It's going to offer a gross towing weight of 5,000 lb with a maximum tongue weight of 500 lb. The ball mount is going to have the permanently attached 1 7/8 inch ball that's going to let you hook up your trailer to your tow vehicle. The shank portion is going to be the portion that slides into the receiver tube of your hitch and then your hitch ball is going to provide a good connection point for your trailer's coupler. The neat thing about the fusion is that the hitch ball is actually welded to the ball mount platform so there's no need to torque it. It's going to be set and ready to go straight out of the box.

You can also see here that we do not have anything hanging below the ball platform so that's a nice smooth, steel surface at this portion right here. The neat think about the fusion is that it's going to prevent theft of the hitch ball. It's also going to eliminate the possibility of your hitch ball being able to loosen up. It's always going to be able to provide a nice, strong and secure towing setup. It's made from a sturdy steel construction. We're going to have a nice black powder coat finish on the actual ball mount with a chrome plated hitch ball. You can see right here that you are going to get a standard 5/8 inch pin and clip.

If you need a hitch pin and lock to lock this to your vehicle that's going to be sold separately. You can find that with part number 7683, but it does come with a hitch pin and clip to get it secured in your hitch. It is designed for 2 inch by 2 inch trailer hitch receivers. It's going to have a nice hollow shank here on the backside. Again, you're going to have a 1 7/8 inch hitch ball. A few measurements that I want to go over with you real quick.

The first one being the distance that we have from the center of the hitch pinhole to the center of the hitch ball. That's going to give us a measurement of about 8 1/8 of an inch. The distance that we have from the center of the hitch pinhole to the back of the shank is going to measure about 2 1/5 inches. This can only be used in the drop position. I measured from the top of the shank to the top of the ball platform.

It's going to give us a drop of 3 1/2 inches. You're going to notice here that on the Curt sticker, they put a 4 inch drop measurement on here. That's an approximate or an estimate or a rounded number, but the exact drop is going to be 3 1/2 inches. Again, that's from the top of the shank to the top of the ball platform. Curt's also going to cover this with a limited lifetime warranty. I'm going to go ahead and show you how it installs inside your hitch. All you have to do is take the shank, slide it into the receiver tube until you get your pinholes to line up with one another and then you simply just insert the included hitch pin and clip. That's going to do it for our review of part number C45151. This is the Curt fusion ball mount for 2 inch hitches with a 5,000 lb gross towing weight capacity. .

  • How to Use 6" Drop Ball Mount and Hitch Bike Rack on 2017 Chevy Tahoe
    I have an alternative solution for you but it will look a little different than the Curt Multipurpose Ball Mount # D210 as the 2" drop you're seeing is pretty standard. To tow your trailer and carry your Thule bike rack I recommend checking out the Replacement Shank for Gen-Y Adjustable Ball Mount # 325-GH-204 which gives you the upper receiver as well as a 5" drop for the lowest receiver. If you have a ball mount with a 1" drop then that's what you'll use for this application, otherwise...

  • Most Affordable Trailer Hitch Receiver And Trailer Wiring Kit For 2020 Audi SQ5
    The most affordable route is to install Trailer Hitch Receiver # e94CR for your hitch receiver then for a trailer wiring kit you can use Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector # C59496. For a ball mount to slide into the receiver that will allow fitment to your trailer, I recommend looking into Curt Fusion Ball Mount for 2" Hitches 1-7/8" Ball # C45151 if your trailer coupler is 1-7/8" or TowSmart Towing Starter Kit for 2" Hitches - 2" Ball # TS94FR if your trailer coupler...

  • Curt Ball Mount with Drop Near 3-1/4 inch
    The closest we have is the Curt part # C45230 which has a drop of 3-5/8 inches or the # C45154 which has a 3-1/2 inch drop and a 2 inch ball or part # C45151 which has the same drop and a 1-7/8 inch hitch ball.

  • How Close to Level Does Ball Mount Need To Place Trailer Ball
    When you calculate the ball mount rise or drop needed, in many cases it won't be possible to find a ball mount that puts you exactly level. As long as the ball mount places you within an inch or two of being level, you'll be fine. A 1/2 inch difference would certainly fall into the 'close enough' category. If you have the choice of being a bit higher or a bit lower than level, it's best to be higher than level if possible. In some cases, the trailer's tongue weight can cause the rear suspension...

  • Solution for Bouncing Trailer with Low Tongue Weight
    A weight distribution system wouldn't really help much in your situation. What you can do to help with the bounce is try moving weight up near the front of the trailer so that you can get the tongue weight of the trailer to be 10-15 percent of the total trailer weight. Getting the trailer as level as possible will also help. If your trailer is sitting nose high currently then that will also contribute to the bouncing. The part # C45154 is a 3 inch drop ball mount with a 2 inch hitch ball....
