Video Transcript for Curt Long Shank 2 inch Hitch Ball Review

Hi there, light duty towers. Today, we're going to be taking a look at CURT's 2" chrome ball.This is a class 2 ball, it's also going to work with class 1. And it has a 3/4" shank on the bottom, which is the diameter of our shaft coming out the bottom that's threaded. And it's also 2-1/8" long, which means that it'll work with drawbars that have a platform between 3/8" thick and 5/8" thick. And it's rated for a 3,500 pound gross towing capacity, which is going to be great for your small utility trailers, we've got one right here we're going to be hooking up to it, but also for other small trailers such as kayak carriers, and maybe a small jet ski trailer as well. The ball is a solid steel construction with a chrome plating on it to protect it against the elements, and it also gives it a nice look.One of the things you can do to help protect the finish and increase the life of your ball is grease it before every use.

That'll just give a little coating for your trailer hitch to pivot on as you're going down the road. Now we're not going to be greasing it today for demonstration purposes, but you can get some grease here at Wheel bearing grease is a really easy thing to use. It's nice to have readily available, and works great on this.When you're ready to use your ball, we're going to take our trailer, unlatch the coupler on it, simply set it in place, and then latch it down. Now that we've got our trailer fully connected with our safety chain, and our coupler pin, and our wiring, we're now ready to hit the road and start towing.Once you get your ball you are going to need a drawbar to install it into, so you want to make sure you choose one with an appropriately sized hole.

Again, this is a 3/4" shank, so you want to look for one with a 3/4 diameter hole in your drawbar. And it's always a good idea to make sure your drawbar is matching the capacities of your ball, because if you get one that's less, you're limiting your ball because you're only going to be able to go with the max that your drawbar is.Let's go ahead and show you how we got the ball installed in the drawbar. Now, we'll begin our installation by removing the nut and washer from our ball, and then installing the ball into our drawbar. We're going to be placing it in this position, as this is really designed for a rise, for the most part, for this drawbar. So we're going to put it there, like that.

And then, on the other side, we're just going to re-secure it with the lock washer and nut.You'll have a couple of flat spots on your ball, so we're just lining those up in our vice to hold it. And then, we can use a 1-1/8" socket to torque the nut the manufacturer's specifications. You usually find that on a tag found on your ball. Now that we've got it torqued to the manufacturer's specifications, we can place it in our receiver, and we're ready to start towing.And that completes our look at CURT's 2" chrome ball.

I love it. It fits very well and is exactly what I needed. I love how etrailer knows what fits your car and that they have install videos too!


Thanks for the quick response to my call.
were able to get the hitch installed time for my son's trip.
A trip with no boat would have been no trip at all!!


Excellent Customer Service kept me from ordering the wrong parts for my hitch. If you're confused -- give them a call!


Great quality steel. Finer threads than all other lower quality hitch balls so prevents threads stripping and not being able to remove or replace the ball in the future.


Fit my Toyota yaris well and works for towing a kayak trailer.


Easy installation,solid design.


Curt brand so the quality is great. Please consider shipping a steel heavy part in cardboard box, not a padded envelope, fast shipping so overall happy with my purchase.


The hitch has worked great over the past year. I pull a 15 ft sailboat and I have had no issues. Customer service was great with a missing part and got it to me quickly. Would definitely purchase again!


No issues a year later


Just wanted to let you know that the trailer hitch is all installed and
works great.

The products are great, we are still happy with them.

Accurate description and fits great.


i needed a 2 inch hitch ball with a 3/4 inch diameter long shank to fit on my tractor 1 inch thick steel drawbar to pull my utility trailer and i ordered it from arrived via usps in a timely manner with no damage and with all parts...i installed it quickly and have been using it for the past several works fine...i recommend etrailer...

Still works great on my old farm tractor drawbar.

Second time ordering and both times product is exactly as described and good price. The problem is with the shipping. Paid for 2-3 day shipping. Was notified the same day that I placed the order that they verified the order and that it was in stock. It took them a week to ship it from the wearhouse. And then another 5 days to get to me.

It is definitely our busy season and I am sorry that we were not able to ship the order to you in the expected time frame.

Fast shipping, Poor packaging, dinged up

I am sorry to hear that your hitch ball arrived damaged. I have sent your information over to our customer service department for them to get in touch with you.
Katrina B - 08/29/2022


Looks great, feels great -heavy duty, handsome and refined ... every thing you could ask for.
Yes, I would recommend it to family & friends and random strangers alike.

Great communication with etrailer always.


Worked great in my stock Chevy S10 bumper. Right length and shank size.


Well, it's a hitch ball! Looks new after a year.


Great price, quality product, and arrived on time...that says it all!


This is a hitch ball! Classic, symmetrical styling with a shiny exterior.


Its a ball


Every part excellent quality. Perfect fit, all parts were exact for my vehicle. Watched the video on youtube for wiring and being a mechanic for over 50 years was able to connect signal lights all from driver side of harness. Instead of leaving plug inside trunk I wired through the rubber outlet to the back of the hitch ready for use. Very happy highly recommend etrailer.

Very happy with products all high quality feel confident using. Thanks
