Video Transcript for Curt Hitch Ball - Trailer Hitch Ball - C40031 Review

Today we're going to be taking a look at part number C40031. This is the Curt 1 7/8" Hitch Ball. It's going to feature the high-rise design that's going to let you easily match the ball height to the trailer height. The trailer hitch ball is going to sit an extra inch above the ball mount platform. It's going to offer fine threads that are going to provide a nice tight, strong grip. This is made from a steel construction with a nice nickel chrome finish that's designed to resist rust and corrosion.

The lock washer and the nut are going to be included. Again, the ball diameter is going to measure 1 7/8". If we take a measurement of the shank length, measuring from the bottom of the platform to the end of the threaded portion, that's going to give us a measurement of 2 3/16" long and it's going to give us a diameter of right at 1". Again, the ball rise is going to be 1" as well, thta's going to this thcik platform portion here. This hitch ball is going to be rated rated with the capacity of 3500 pounds. This portion here is going to go through the ball hole on the ball mount.

You simply place on the lock washer, followed by the nut to get all the way tightened down. Then you will need to torque this to the specifications listed by the manufacturer. Once you have that all set, everything should be ready and ready for use. That's going to do it for today's review of part number C40031. This is the Curt 1 7/8" Hitch Ball. .

Can't beat it for the price, and it's solid and shiny as can be. Only problem is the whole body is all round, with no edges to put a wrench on to tighten the nut down. I got my big pipe wrench on there, and it worked fine, but scuffed up the chrome a little bit.

They are all working great, thanks. No complaints.



by:

Seems to be a decently constructed ball. I havent used it to tow my motorcycle on the trailer yet so hopefully its durable.



by:

I've made several purchases over a couple years and have always been very satisfied with E-trailer. Always correct product and timely delivery. When I need a part or a draw bar, E-trailer is where I start looking and usually need look no further.



by:

The 1 in. rise hitch ball is just what I needed to level my cargo trailer behind my trike.



by:

good quality and fast deliver. Have always been satisfied with previous purchases. Will recommend.

Really pleased with the service I received on my order. Received in four days with regular shipping, got it installed in time for my outing. THank you

Thanks.

Everything arrived as stated. Hopefully soon I will be able to install it on my vehicle.
Thanks!!

My poor rating is all about the product and no reflection on etrailer - As others have commented this hitch ball needs to be made available in Stainless Steel. It has, so far, functioned as advertised and fits my requirements. However, the material and finish are poor. I use this to tow a 2000lb GVWR trailer (Hélio O2). I routinely clean and grease my hitch coupler and this hitch ball. In the short time and relatively few miles I've used this the finish and base material are wearing away rapidly (see attached pictures taken at time of this review).
Also, to be nit-picky: It does not make sense why the 2" Rise (Item # C40034) is priced less than the 1" rise (Item # C40033).

I just opened up my new Class 5 Curt XD hitch and have not yet installed it so my comments are based on first impressions only. It is very heavy duty - and heavy at 40 lbs. - made of extremely thick metal and outfitted with quality Grade 8 bolts with square necks so they won’t turn when torquing on the nuts to attach the main tube to the side mounting plates. My bolts are plated yellow (which I like) rather than silver as you may have seen in some online photographs. It is substantially beefier than my existing Grade 4 hitch and superior in every way. It’s an impressive piece of hardware. I cannot imagine anyone being disappointed with it on specifications, quality, strength, and general appearance. It’s a beast. What I AM disappointed in is Curt’s packaging and the condition in which the hitch arrived. (This is NOT a reflection on etrailer.com as the hitch arrived in Curt’s original packaging.) The unassembled main tube and the two side mounting plates come bundled together with nothing separating them but shrink wrap. No cardboard, plastic, even paper coming between the metal surfaces - just shrinkwrap probably not even a couple of mils thick. With basically metal-to-metal contact in an oversized-box with the bundle jostling around, it would be a miracle if there were no scratches, gouges, or some type of damage to at least one piece, which is exactly what happened to my hitch. The main hitch tube, on the exterior facing plane, on the driver side where I’ll see it every day, has some gouges on it that go through the powder-coating to bare metal. I can - and will - paint them to prevent rust (and, therefore, have to paint the whole hitch to match). But the gouges will still be noticeable as they go through the thicker, pebbly, powder-coat finish and will undoubtedly still appear as depressions in the surface even once painted. I fully realize this kind of surface damage will almost certainly happen with regular usage of the hitch anyway and that it’s certifiable to demand absolute perfection in anything. But if you are someone who cares about the aesthetics of your equipment and keeping it looking new for as long as possible, it is very disappointing to receive such an expensive and prominent piece of hardware damaged right out of the box and requiring immediate repainting. The plastic parts bag had also ripped open in transit, with nuts, bolts, shims, etc. rattling around in the box. I am dumbfounded that Curt packages such a high-quality piece of equipment so shoddily where such damage is virtually unavoidable. I bought from Curt solely due to their being an American manufacturer and to support American workers so this is doubly discouraging. It’s a trivial complaint in the big scheme of things and not worth demanding a replacement over. Just be aware that unless Curt changes their packaging practices it is very possible you will have the wind taken out of your towing project sails just as I have. Again, this in no way reflects on etrailer. My experience to date with etrailer (website, educational resources, staff reviews, ordering, tracking, email contact, etc.) has been beyond exemplary in every way. They rank as a Top Five online retailer in my opinion, maybe even the best.

Hitch Ball worked out great getting my trailer at the right level position.



by:

Needed an extended ball mount for my new Jeep in order for the utility trailer tongue to clear the spare tire. Item is exactly as described on site and arrived earlier than expected.
etrailer has always given me great customer service. It is my go to place for all towing and trailer needs.



by:

I would use the company again. UPS lost the product i purchased, and etrailer called me to offer to replace it at no additional charge. I work for a large corporation and the professional speed, and the way they handled the issue was great.



by:

Excellent tow ball. Solved the problem that the original towing hitch was to low for our tandem boat trailer.
Has been used extensively over the last year towing our boat without any issues.
Highly recommended.
etrailer.com were excellent to deal with.



by:

A great deal. Well used with my new 14k dump trailer and working great!



by:

etrailer is great they have what I need and are fast to ship

  • Does the Curt 2" Hitch Ball # C40033 with High-Rise come in a 1-7/8" Version
    We do have 1-7/8" Curt hitch balls like the 2" part # C40033 that come with a high-rise. If you just need a 1" rise then you will want part # C40031, but if you need a 2" rise you will want part # C40032 instead. Both are rated for 3,500 lbs

  • Recommended Ball Mount With 7 Inches of Rise for a 2012 Hyundai Sante Fe
    The Draw-Tite Ball Mount # 2793 does have the needed 7 inches of rise, but from the center of the pin hole to the closest edge of the upright gusset is only 3 3/4 inches, so I don't think it will work with your vehicle, unfortunately. That being said, we do have a couple other options available for you. The Brophy # EA80 has the needed 7 inches of rise, but at the closest point it is 4 1/8 inches to the center of the pin hole. This does rise pretty quickly and may still work for you, but...

  • Ball Mount Recommendation with a 6 inch Drop for Use with a Towing Bike Rack
    The Ball Mount part # D-28 would be your best option sounds like. It is long enough that you could mount a towing bike rack to it like part # S64664 that you are interested in, it also has a 6 inch drop which would be the closest drop ball mount we carry to what you need and would work well for you. You would not want to add washers to the ball mount, but you could use a high rise ball that has a rise built into it like part # C40033 that is a 2 inch diameter hitch ball with a 1 inch rise...

  • Hitch Recommendation for a 2002 Volkswagen New Beetle
    The Draw Tite hitch part # 24679 that you referenced is the correct hitch for your 2002 Volkswagen New Beetle so it would be the right choice. The thing about Class I hitches like this hitch is that you can only use the recommended ball mount for the hitch otherwise you void the warranty of the hitch. Draw Tite says that you have to use the part # 3593 as a ball mount in the rise position so that is the only one I can recommend for you. For a hitch ball you could not use the part # C40031...

  • Multipupose Ball Mount to Tow a Trailer and Bike Rack at Same Time that Doesnt have a Drop
    You wouldn't want to use MaxxTow MT70070 anyway because it will reduce the tongue weight capacity of the trailer hitch by 50 percent. The Curt multipurpose ball mount # D210 is going to be the best option. To overcome the 2-1/4 inch drop you can use a ball with a rise such as # C40034. This is a 2 inch ball rated for 6,000 pounds. It has a 2 inch rise so the drop of the ball mount would only be 1/4 inch. We also have ball # C40033 with a 1 inch rise. If you require a 1-7/8 inch ball...
