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.

@Jason True, but we're glad to hear it's working well for you...


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.


Perfect as always.


The ball fit and worked with no Issues


Work like a charm


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


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.


I was very suspicious how will it fit and suit Dodge Challenger. But when I received trailer hitch, and by they way it travelled across the planet to reach me, I was totally impressed with the quality, ease of installation and accessories which I ordered with it. I basically installed it myself with a help of a friend, it took about 30 minutes to fix it. It really saved me as I needed the trailer to transport my bike to the race track and I didn't want to change the car.
So the conclusion, I own it for more than a year and have zero issues or complaints about the hitch or accessories. I used to travel long and short distances and in average I use it every second week. You barely can notice it when you remove drawbar so it is very good solution.


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.


just what i needed to go with my hitch,carrier so i can hook up my trailer to my chev trax to pick up items too big for the trax. also being able to take items to the transfer station to dispose of.

working well and can use my trailer in many ways. glad i bought it


For my 1 ton total Harbor Freight utility trailer, this ball, with a Curt Class II drawbar, on my '11 Mini Countryman S, is overkill, but I'm much happier knowing that the hitch and ball are working at far below maximum capacity. A mechanic neighbor had the tools needed to get the nut torqued properly. It's all very solid. Just part of a kit to create a part-time pickup truck where I can leave the "bed" at home.


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


High quality


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!


All the items in my order arrived today. Thanks for your continued follow-up on this order and the speedy shipping once you had the item on hand. I also appreciated the installation video and pictures on etrailer. com. I routinely recommend that my customers reference your website for install instructions and product explanation videos. Keep up the good worK.


very good product easy to install I recommend this product and by the way the service is very good thank you


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!!


Perfect fit.


High quality products!!
“NOAH E” helped
me selecting the right set up! Great customer service highly recommended!!


As described. Super fast shipping.


This product is great. Easy ti install. Just as advertised and delivery was very fast. I would recommend buying from etrailer.



Still working great. Saves me money every time I use it because I dont have to use my one ton on most of my hauling.


From the minute I discovered for my new trailer hitch needs, called them on the phone, got to a live person who helped me order every item I needed, was alerted that my items had been delivered, and opened the door to see a big cardboard box that actually was still in one piece, it was a topnotch experience. Talk about great customer!

I will attach a photo of my hitch once it's installed on July 29.


My second Curt hitch. I like the appearance of the round tubular hitch. Service reliable and delivery quick. The only shortfall on the instructions was that it was not clear which holes in the frame got the bolts that were fished in, and of course I got it wrong the first time. I had to remove both bolts to reinstall in holes farther forward. Otherwise, fine product and instructions.


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.
