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.


Comments
They are all working great, thanks. No complaints.

Review from a similar High-Rise Ball in Trailer Hitch Ball


Exactly what I needed for my 4 wheeler to keep the tongue of the trailer from being too low. The price was good and the delivery was quick. The only thing I had to do was to enlarge the hole to fit the one inch shank. Thanks etrailer for having what I needed.


Comments
Still working out great a year later. The trailer tongue does not hit the ground when I tow it with my four wheeler.

Review from a similar High-Rise Ball in Trailer Hitch Ball


I ordered the 30000 lb. ball hitch for a gooseneck on my 01 F250 super duty. It arrived at the time that e trailer said it would. I was able to choose the way the item was shipped which saved me money over other online options. I just put it in since it was a raw Steel ball I hit it with a coat of flat black enamel to keep the rusting to a minimum. It is installed and ready to pull. I don't have a gooseneck trailer but now if I need to pull a rental or a friends I can. I like doing business with places directly like e trailer and cutting out the big box places that are not easy to communicate with if there is a problem. There wasn't any which is even better.

Review from a similar High-Rise Ball in Trailer Hitch Ball


So the customer service is fantastic. I ordered the BWX2000 and it showed up missing the shank. It was not etrailer’s fault as the shipment initially contained everything but the carrier messed up and the package didn’t arrive with the shank. I spoke to autumn in customer service and she did absolutely everything she could to get me the 2.5 inch shank I needed but ended up sending me the 2in receiver by mistake. Again I wasn’t upset because I did not specify and by the time I realized it was wrong the part was already on the way. Long story short I got the 2 in shank in the next day, this shank would work but it was not exactly for the load I wanted to safely pull. Anyway I ended up finding the correct shank, ordered it and it is one the way. Now I will have both the 2 and 2.5 in shank for the same distro hitch but guess what I am completely fine with it backside I have two trucks, each with different receivers so for just a little bit more I can use this hitch for both my trucks just fine. Everything happens for a reason and I was completely happy with how autumn helped me out. She was great and called me back several times to let me know what both she was trying to do and get assistance from several of her techs. Thank you and I will certainly do business with autumn and etrailer again. Autumn was really nice to me and did everything she could to help me out. Thanks again. Jason

Review from a similar High-Rise Ball in Trailer Hitch Ball


exactly as shown. video of the ball answered questions that I had. easy tightening. Some reviews stated that the ball didnt have cuts for tightening for two wrenches one to tighten the other to keep it from turning. I didnt have a problem one lock washer is chinsed down flat your good. Put it in your hitch for a quarter more turn and your good. with 2" drop this allowed it to become zero drop which was my goal . ordered from etrailer before and will if need in the future. live in cali so it took a few days but it was shipped out a couple hours after I ordered it. Now my bassboat trailer is level

Ask the Experts about this Curt Trailer Hitch Ball

  • Multipupose Ball Mount to Tow a Trailer and Bike Rack at Same Time that Doesn't have a Drop
    You wouldn't want to use MaxxTow dual hitch receiver # 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...

  • 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...

  • 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,...

  • 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

  • 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...
