Video Transcript for Curt 3500lb Chrome Hitch Ball Review

Hello neighbors, it's Brad here at etrailer. And today we're taking a look at the Curt 1 7/8 Inch Ball. Now this is with a One Inch Diameter Shank. Now this steel ball is gonna be a sturdy, great option for a trailer with a 1 7/8 inch coupler. Now it also has the one inch diameter. So when shopping for your ball mount, make sure that you are getting one with a one inch opening so it matches the diameter of the shank.

The shank length on this is 2 1/8 inch. So you also wanna make sure that it's going to have threads sticking out when you tighten up your ball to your ball mount. Speaking of tightening up the ball mount, it's gonna be important when you install this, which is pretty easy, to torque this to the proper specs. Now you can see this does include the nut and the lock washer here. You're simply going to put a wrench on this nice flat slotted part, and then tighten this down with a torque wrench to the proper specifications that the manufacturer recommends.

Now, it's very important to torque this down with the torque wrench. That way it's not too tight or too loose when towing. So if you don't have a torque wrench, we'll sell those here at etrailer, or you can rent one at an auto parts store, generally. But it's very important that you have this torqued properly And that way you know, that this isn't going to wobble loose when you're towing something. Now the steel construction has a nice chrome finish on it.

So it looks really good. Now, sometimes when you hook up to your trailer, it's good to put a little bit of grease here, and that's going to maintain that chrome appearance for a long time. Now, as far as the weight rating goes, this is good for 3,500 pounds, which is a decent amount of weight. So before hooking up to your trailer and towing, you're also gonna wanna make sure that the rest of components are up to snuff with that weight rating. And that includes your ball mount, your hitch, and also your vehicle.

Now you wanna take the lowest number out of all of those and stick with that when towing and that way you're not overdoing it. And that was a look at the Curt 1 7/8 Inch Ball with the One Inch Diameter Shank. Thanks for watching..

Durable chrome ball has a 1" diameter x 2-1/8" long shank with fine threads for a superior grip. The nickel chrome finish provides corrosion-resistance.


Buy from them. They know what they’re d oing.


Works as it should.


Hitch is great, easy install. Rusts a bit but that comes with the territory. I bought this because it was so helpful to have all solutions needed from the same company. I purchased with an after market hitch assembly for Ford Explorer.


Good ball...good price.


Made in China. Chrome plating wore off after 3rd trip to dump. Now looking for US made ball.


Works as expected. I really appreciate that you ask for a review after I have had a chance to really use and test the item. Most companies ask for a review before the item is even placed into service, which results in useless reviews.


Just what the doctor ordered! Great qu ality.


The Hitch is great. Unfortunately the locking device I purchased with the hitch will not work on the inside due to restrictions of barriers within the area that the pin is inserted. This should be noted for sales people when being ordered with a Tesla Y. I will use the locking device on the side of the hitch and a small lock through the pin in the inside area of the hitch.


Well built and functions as expected

Amazing customer service as usual!I love your products, they are heavily road tested and working excellently! I got a friend to buy a trailer hitch too, since it was so easy!

Trailer ball and wiring harness fit perfect...
out of the 5 holes in the trailer hitch did not line up. One was about an 1/8" off and the other was over a 1/4" off. I went to my local Fastenal store and bought a carbide burr $28 and about an hour of elongating the holes, finely got the them to fit
Bought the Nissan Murano brand new about 8 months ago.
Not happy about the extra work it took to make it fit...


Fits good, chrome holds up good.


Quality ball. Does the job. Reasonable price. Prompt shipping.


Although it was an extraordinary delivery time, I appreciate being kept informed of the progress.


Very happy with so far ( I haven't installed my hitch yet). Their service to date has been excellent. I am a trailer newbie, so needed help choosing the towing components. The 2 folks I spoke to at could not have been more helpful. They answered all my questions and help select the correct components I needed. Would definitely recommend!!!


I have a 2015 Rav 4 and I ordered the wiring harness with the hitch, ball and receiver and it arrived the next day undamaged. I am happy with the quality of this product.


I worked with Lori B. for a return and an order. She handles both very well with professionalism and we jokes a little bit which made the phone conversation very pleasant and comfortable. Two thumbs up for her. My next order, I'll ask for her again by name. Thank you.


Nice hitch ball. Fits the trailer tongue hitch perfectly. Delivery in only 3 days.


I was told about etrailer from an acquaintance. He said your prices were the best and your customer service was outstanding. After placing my order and receiving my products I have to say, I agree with him 100%! Ordered my items on Friday receive them on Monday... Good quality, fast delivery, fair price what else can I say! I will definitely refer etrailer and use your company in the future.


I've always been happy with Curt products, this new ball seems to be no exception. It's exactly what I needed to complete my transformation from a class II hitch to a class III.


I Love the quality of the merchandise works great be ordering more it came quite. Thanks


Will buy again.

I called the customer
service line to ask questions about fitment and confirm I will receive the right products (ball mount, ball, and lock). They were EXCELLENT and if they weren't sure, they did the right research to confirm. Definitely worth buying from them.


Love my hitch! Gets me and my gear where I wanna go! Dylan really helped me get the perfect equipment for my 2012 Xterra. I am not super car smart but etrailer always gives me expert assistance.


The products are well made and I look forward to using them. I only wish etrailer fulfillment would have asked a question of "is this ball for this receiver". Because being new to all of this, I ordered the wrong size ball for the receiver and it would have been GREAT to have a second set of eyes to see this. I know it's my issue.


Great product! Fast delivery! Great customer service!


Smooth, no defects, wrench knotches on base of ball, awesome feature. Many don't have that. Very solid. Fits snug in a one inch hitch hole.

Ask the Experts about this CURT Trailer Hitch Ball

  • Will the Curt Hitch Ball # C40002 Fit in the Ball Mount Included in the Kit # C45036
    Yes, the Curt Class III Ball Mount with 2" Ball # C45036 has a hitch ball shank diameter of 1". The 1-7/8" Hitch Ball # C40002 that you asked about has a shank diameter of 1" as well so it will fit just fine. You will just want to make sure that you get the nut torqued before towing. Please keep in mind that the 1-7/8" hitch ball has a weight capacity of 3,500 lbs so the ball mount that is rated for 7,500 lbs will have the same capacity as the lower hitch ball.

  • 1-7/8 inch Hitch ball for Trailer Coupler
    If your ball mount has a standard 1 inch diameter shank you could use the Curt ball part # C40002 for a 1-7/8 inch hitch ball. The other popular size is 3/4 inch diameter which would mean you'd want the part # 19256. I also attached a link to a page that has all of the 1-7/8 inch hitch balls we carry as well.

    The 1-7/8" Hitch Ball # C40002 will require a 1-1/2" Socket # ALL643210. You will need a wrench that will open to 1-5/8" to hold the ball in place while torqueing the nut.

  • 1-7/8" Hitch Ball Compatible With Curt Ball Mount C45296
    Absolutely! For the Curt Ball Mount for 2" Hitches - 2-1/4" Rise, 3-1/2" Drop # C45296 the Curt 1-7/8" Hitch Ball # C40002 will fit perfectly. Keep in mind that the 1-7/8" hitch ball is only rated to 3500lbs, so even though the # C45296 is rated to 7500lbs you will need to use the lower of the two ratings.

    The 1-7/8" Hitch Ball with Internal Thread # EI1C-C is the only 1-7/8" ball that we have with internal threads and is 3/4" diameter. We do not have a ball with internal thread that is 1" in diameter. We also have the 1-7/8" Hitch Ball - 1" Diameter # C40002 which has the 1" diameter but is not an internal thread option.

  • Ball Mount Recommendation for 2013 Mazda CX-9 for Towing Uhaul Trailer
    You are on the right track with picking out a ball mount. You will want something that will give you a 4 inch rise so that your trailer can be towed level. Not every trailer has the same height though so it's kind of hard to recommend a one-size-fits-all ball mount but since we know what you need we can recommend the correct rise for your application. For that we have the Curt ball mount part # C45070 which has a 4 inch rise. For a 2 inch ball you'd then want part # 63845 or # C40002 for...

  • Recommended Hitch Ball Shank Length for Curt Ball Mount for 2 Inch Hitches
    For the Curt Ball Mount for 2" Hitches - 2-3/8" Rise, 3-5/8" Drop - Angled Shank - 7,500 lbs # C45230 you will need a hitch ball with a 1 inch shank that is just over 2 inches long. For a 1-7/8 inch ball diameter, I recommend the Curt # C40002. For a 2 inch ball diameter, I recommend # 40038. These shank lengths of 2-1/8 and 2-1/4 inches will allow for the ball platform thickness as well as the lock washer and nut.

  • Solution for Ball Mount to Move Trailer up Steep Driveway
    The best solution would for a ball mount to help you move your trailer up a steel driveway would be one with a good amount of rise. An adjustable ball mount would be the best for this, something like the Curt Channel Style Adjustable Ball Mount - 5-1/4" Rise, 6-3/4" Drop # C45901. I'm not sure what rise or drop you use now, but this would give you some additional rise and allow you to use the rise or drop you need for normal towing circumstances.

This ball mount comes with a pin and clip but you can lock the mount with the Curt Lock Set for Adjustable Channel-Style Mounts # C23556.

  • Recommended Ball Mount To Replace Curt C45901 With Missing Parts
    I reached out to my contact at Curt and while I have a complete replacement option for you, the ball mount section of the # C45901 is not available separately. Since there is no other ball mount option of the same style that will fit your shank, you will need to purchase another # C45901. In addition you will need a hitch ball with a 1" shank, the 1-7/8" # C40002, 2" # 40083, or 2-5/16" # C40005. I included a video of the # C45901 for you to take a look at.

I attached an install video for this for you to check out as well. Then for trailer wiring you'd want the Tekonsha kit part # 118727 which installs easily and has a very reliable converter box.

    For your 2017 VW Touareg, I think you are looking for the Curt Vertical Receiver Adapter - 2" to 2", 4-1/4" Long, 2-7/16" Drop # C45013. I recommend using the Anti-Rattle Trailer Hitch Receiver Lock for 2" Hitches - 2-5/8" Span, # 63232 with this application to reduce movement and noise while securing your accessory. If you are looking for a ball mount, I recommend the Curt Vertical 2" to Fixed Ball Mount - 12-3/8" Long, 2-1/4" Rise, # C45003. This mount can use a 2" Hitch Ball - 1"...

    Any trailer hitch ball that has a 1" diameter and at least 2-1/8" long shank will work with the Draw-Tite Ball Mount part # 2923. For a 1-7/8" hitch ball I recommend part # C40002, part # C40004 for 2", or part # C40005 for 2-5/16". I have also attached a selection of our hitch balls that will work with the above ball mount for you. To protect your ball mount/hitch ball, I recommend using the Trailer Hitch Receiver Lock part # e98880.

    For reasons unknown, Curt actually rounds up to the nearest number for advertising their ball mount, which is confusing, but the true drop is 7-1/2 inches for the Curt Ball Mount for 2" Hitches # C45100. So this ball mount will work to get the drop you are looking for; along with the ball mount you will need a pin and clip or lock as well as a hitch ball.

Since adjustable shank uses the standard 5/8" pin and is hollow you can absolutely use the Anti-Rattle Trailer Hitch Receiver Lock for 2" Hitches - 2-5/8" Span # 63232 you were looking at to get rid of any rattling.

This ball mount slides into a 2" receiver tube opening and works with hitch balls that have a 1" diameter shank.
