Video Transcript for Curt Hitch Ball - Trailer Hitch Ball - C40033 Review

Today we're going to be taking a look at part number C40033. This is the Curt Two-inch Hitch Ball. It's going to have the one-inch rise, and it's rated at 6,000 pounds. The high-rise design is going to let you easily match the ball to your trailer height. The trailer hitch ball is going to sit an extra inch above the ball mount platform, so the rise is this portion right here. It's going to offer fine threads. These are going to provide exceptionally tight, strong grip once installed.

This is a steel construction with a nickel chrome finish, so it's designed to resist rust and corrosion. The lock washer and the nut are both included. The ball diameter is going to measure 2 inches. Here at the shank, it's going to give us a shank length measuring from the bottom of the platform to the end of the threaded portion of 2 and 1/8 of an inch. It's going to give us a shank diameter of one inch. The ball shank diameter, this is just something to keep in mind, that should be within 1/16th of an inch of the ball mount hole diameter on the ball mount.

Keep that in mind when choosing a ball mount or when choosing a hitch ball. The rise, we'll take a measurement of that. That's going to measure right at one inch. Again, the hitch ball is rated with a capacity of 6,000 pounds. Very easy installation. All you have to do is place the threaded portion down through the ball hole, and that would be on the ball mount.

Place on the lap washer followed by the nut, then you need to get everything tightened down and torqued to specifications. It's going to come with a nice little instructional tag that's going to be installed on the shank. You want to be sure to remove that. That's going to have the proper torque rating on there, and some other information that you need to go off of. That's going to do it for our review of part number C40033. This is the Curt Two-inch Hitch Ball.

2" Hitch Ball - 1" Rise - 1" Diameter x 2-1/8" Long Shank - 6,000 lbs - C40033

Average Customer Rating:  4.8 out of 5 stars   (694 Customer Reviews)

2-1/8" Long x 1" diameter shank featuring a ball with a 1" high rise above the platform. Fine threads provide superior strength, and the nickel chrome finish offers corrosion protection.


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).


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


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.

Paul D.




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


The 1” rise gave me the perfect height to level my trailer that was not possible with any combination of receivers and balls. I tow an enclosed cargo trailer 10,000 miles per year, some of it on gravel or minimally maintained roads. If the load is not level, the cargo tends to migrate forward or aft, no matter wow well it is secured. This can make the load dangerously balanced. This ball makes possible perfectly matched height between my truck and trailer. I really wanted to give this item the perfect five star rating. The only flaw is how easy it has rusted. It does not affect its function, but too easily rusted is a flaw (in my opinion). Otherwise, I wholeheartedly recommend this product.

Rust can be troublesome no matter when it occurs. You will want to grease the ball every now and again to help protect. A multi purpose grease like part # L11316 will do the trick.


I like the extra meat this ball has. It also enabled me to get the running hieght "just right" for the towing application I use it with.



Still Working great!


Fast delivery and AUTHENTIC Curt product. Thx etrailer!


The perfect method to raise the trailer tongue for level, while keeping the tow vehicle unchanged.


Curt brand 2 inch hitch ball with 1 inch rise and 1 inch diameter threaded shaft. The picture shows a dull finish but it was bright chrome. Excellent quality. Fast shipping from etrailer as usual. A return customer.

We purposely dull the finish so we can photograph the ball. If we didnt do so, the glare from the cameras flash would make it hard to make out any detail on the trailer ball.


I needed this special 1 inch rise hitch ball to get my bassboat with tandem trailer level. this was only place I could find this item.. arrived as expected and nice and shiny.



In follow up to my review I would like to recommend that The company start making these out of stainless steel. I just bought a new 1 rise hitch ball and it is the third one I have bought over the last three years because they rust up so badly. I have tried the Reese hitch ball grease and plastic covers however by the end of winter when I am ready to get the boat and trailer out for the summer the hitch ball is so rusted I cant even wire brush it off. I really like these Curt hitch balls for their 1 rise which levels my trailer nicely but it is a pain to replace them every year. This last one got so rusted I had to use a reciprocating saw to get it off the hitch. In follow up to my review I would like to recommend that The company start making these out of stainless steel.

I used this in combination with a 7" Rise, 8" Drop - 15-1/4" Long Brophy ball mount on the front hitch of my 2013 F 150 to get the right height for my trailers.
This is a good way to fine tune the correct trailer tongue height.


This ball is the perfect way to add clearance and height to my travel trailer ball mount.


Hitch ball was just what I needed, quality item. Shipping was fast even for economy.
My third purchase from etrailer and I'm very happy.



Doing what its suppose to. Happy with hitch and service.


The shipment arrived a day early, and everything fit and will be enjoyed this summer as I travel. Looks like quality merchandise from a quality supplier.


I haven’t towed my trailer with new ball yet, so only 4 stars. Mounted on my hitch and appears to be sturdy. Only complaint is that there is no flat edge on ball side to get a wrench to grip. Had to use a channel lock straight jaw wrench to grip. My old ball has an edge so you can get a wrench on the nut and also ball side. Hope that makes sense.


Product as described. Allows me to tow my trailer at precisely the right height as I use it with a 2 inch drop ball mount to make it effectively a 1 inch drop.


This ball has held up well after a year of service. I tow a 3500 lb boat once or twice a week year round. The trip is roughly 100 miles round trip so this ball has some miles on it.

Robert B.


It’s still getting the job done.


Received as described. I couldn't find a mount that gave me the right rise, but the extra 1" rise with this ball worked well for me.
Nice chrome finish and looks solid. Only complaint I have, and I consider it a BIG complaint, is the lack of "flats" so you can hold the ball with a large wrench and torque the nut if you have the correct range torque wrench. Otherwise, you have to wrap the ball with duct tape or ? and clamp in a vice ? Ridiculous to make a customer do that! Being new to towing, I never gave it a thought when I bought this ball. I first called Autozone and they did have a wrench that went up to 250 ft/lb and a vice and said to stop by. Luckily, I thought of my local U-Haul and they made it easy by torqueing the ball with their impact gun. I never thought about an impact gun. Much easier. I'd give 5 stars except for the lack of flats.
PLEASE, all ball makers, this is the 21st century. Put flats on every ball. Us customers will appreciate it!


I've been struggling trying to get my trailer leveled and still be able to use the jack to get the tounge off the ball. I either had to put up with having to manually lift the tounge the final inch or use a receiver that's too high. I found this ball on etrailer that is one inch higher than a standard ball. It eliminated my problem (and gave my back a break). They have one with a two inch extension also. Someone was smart enough to figure this out and etrailer sells it. Two thumbs up for etrailer.


Got a new truck. My boat trailer is low. At times, I had a difficult time swinging the front trailer wheel up and back after hooking boat to the truck when the trailer was on soft ground. This 1 inch riser ball solved my problem.


I needed additional height at my hitch to utilize my trailer jack . This solved my problem. Quality is good and my back thanks you . I no longer need to lift my trailer tongue just to engage the jack .


The photo does not do the product justice. High chrome finish matches my new aluminum hitch perfectly. is the only choice! Cheap shipping and follow-up at every step makes this the go-to trailer site on the web.



This ball is exactly as advertised and the delivery was faster than I expected. I needed a heavier weight rated ball for my weight distribution hitch and finding this one with the 1 inch rise was just what I needed. Thanks e-trailer for great selection and service.


Worked Great to raise my trailer the 1 inch i was looking for!



Excellent works great after a year is use. Would definitely recommend!


Good ball. Nice chrome. Would be little easier to install with flats on the top part to keep it from rotating when torqueing the nut against the lock washer.

Gave me the additional height I needed that I couldn't find in a riser draw bar!

  • 2 Inch Trailer Hitch Ball with 1 Inch Rise
    There is not a hitch ball I am aware of from any manufacturer with the rise and 3/4 inch shank you are seeking. The closest thing we have is # C40033 which is a 2 inch ball with a 1 inch rise and 1 inch diameter shank. If you need a different ball mount for compatibility with this hitch ball, let me know the rise or drop needed. I've attached an article to assist.

  • How to Get 7 Inches of Drop With an 8 inch Drop Ball Mount
    To get 7 inches of drop you will need to use your 8 inch drop ball mount you currently have and then use a high rise ball like the part # C40033 that has an inch of rise built into it. This will put you right at 7 inches of drop. This ball has a 1 inch diameter shank and is a 2 inch ball.

  • High Rise Hitch Ball Recommendation for 2 inch Ball and 6k Capacity
    None of the high-rise hitch balls we offer are stainless steel. They are all chrome plated steel like the part # C40033 which fits your other criteria. It's got a 1 inch shank, one inch rise, 2 inch diameter, and 6k capacity.

  • When Changing Rise/Drop Ball Mount Does Friction Sway Control Ball Height Need to Change
    It wouldn't ever be necessary to put a rise into the ball of a sway control setup. So what that means Barry is that since the ball always mounts to the side of the ball mount platform it basically will always be at the correct height. I attached a picture with a pretty extreme example that shows a ball mount with a lot of drop used with friction sway control and you can see that the sway control is leveled properly.

    The part # 63845 is a standard height hitch ball. If you need additional inch from a hitch ball that fits the same criteria as the # 63845 you'd want the hitch ball # C40033 which is the same except 1 inch taller.

  • Can Taller Hitch Ball be Installed in Curt Ball Mount # C45036
    The ball mount that comes with the Curt part # C45036 has a 1 inch diameter ball hole which means you can install the hitch ball part # C40033 in place of the included ball and have the same diameter hitch ball but 1 inch taller.

  • Material of 2 Inch Trailer Hitch Ball With 1 Inch Shank and Rise
    There are very few trailer hitch balls with a rise, and all of them are made of chrome-plated steel, including the 2" trailer hitch balls. Both 2" hitch balls have a 6,000 lb capacity and 1" diameter shank with the difference being the amount of rise; the Curt 2" Hitch Ball # C40033 has a 1" rise and the Curt 2" Hitch Ball # C40034 has a 2" rise. Most trailer hitch balls are made out of chrome-plated steel now and they are just as high-quality as their stainless steel brethren while...

  • What Is The Highest Ball Rise Compatible With The Curt # D210?
    The Curt Multipurpose Ball Mount with 2" Receiver for Bike Racks and Cargo Carriers - 7,500 lbs # D210 does not have an adjustable rise, so a higher ball would be your only option for this product. The measurements, which I've attached will give you 5-13/16 inches between the top of the drawbar where the ball mounts to the bottom of the bike shank. You will be able to fit a hi-rise ball like # C40033 on this because you will have a measurement of 3-3/8 inches above that draw bar. This...

  • Do You Carry a 2" Hitch Ball With Rise Having a 1" Diameter and 3" Long Shank?
    We will only have a 2" ball with a 3" shank and no rise # C40020. Our 1" Rise # C40033 and 2" Rise # C40034 balls only have a 2-1/8" long shank.

  • Height of Curt 2 Hitch Ball # C40004
    I went out to our warehouse to take a look at the Curt 2" Hitch Ball # C40004 that you referenced and I measured a height of 2-3/4" from the mounting base to the top of the ball. I have attached an image to assist. If this doesn't provide the height you need we also have the 2" ball available with an additional 1" rise with part # C40033 or an additional 2" rise with # C40034. These rise measurements would be added to the 2-3/4" height mentioned above.

    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 Height on 2009 Acura MDX and Ball Mount Compatibility
    When we installed 2-inch Curt Class III hitch # 13354 on a 2009 MDX we found that the top of the receiver opening was indeed 17-inches above ground, although this can vary slightly from car to car depending on the amount of tread wear and factors like passenger and cargo weight. Since all tow vehicles will exhibit some degree of rear-end squat when a trailer is hitched to them, it is a good idea to have the starting height of the hitch ball on the MDX about 1-inch HIGHER than the top of...

  • Does a Long Ball Mount Reduce my Hitches Capacity
    When using a ball mount like the Curt Ball Mount part # D-26 it will not have any effect on the tongue weight rating of your hitch. When using a direct connect type extended ball mount there are no issues. This only comes into play when using an extender like the Curt Hitch Extender for 2" Hitch Receivers part # C45791 or others like it. In this case it drops the weight rating of your hitch by 50%.

There is not a 2-5/16 inch hitch ball that has a 1 inch shank. If you want a ball mount that will work with this, I recommend the B&W Heavy-Duty Ball Mount - 1" Rise, 2" Drop - 8-1/2" Long - 16,000 lbs # BWBMHD30010.

This hitch ball has a 1 inch shank diameter. You need to measure the diameter of the shank hole for the hitch ball on your Class I hitch to see if it has a 1 inch or 3/4 inch diameter.

  • Replacement Hitch Ball to Increase Ball Height
    It is always important to keep your trailer level when hitched to your tow vehicle and the two simplest ways to accomplish this are either a high-rise hitch ball such as the two you reviewed, parts # C40033 and # C40034, or a ball mount with the amount of rise you need. Either option will work. The hitch balls you referenced are shown in the linked photo; I have added the dimension above the mounting surface for each ball.

  • Will a Loading Bike Carrier and Trailer Towing Together with Dual Receiver Cause Rear Vehicle Sag
    The extra weight of the loaded bike carrier will likely cause the rear of the vehicle to sag slightly more when the trailer is also coupled but it should not be drastic enough to necessitate a different set up. Using a ball with a rise such as # C40033 might actually be too much increase but the only way to know for sure is to see if there is excessive sage with the current set up. The issue though is that by using dual receiver # MT70066 the tongue weight capacity of the trailer hitch...

  • Longer Ball Mount and Rise Hitch Ball Solution for Needing 1-1/2 inch Drop
    The ball mount part # EA20 is 9-3/4 inches from pin hole to ball hole like you mentioned. We do have taller hitch balls like the part # C40033 which has an inch of rise built into the ball that would put you at 1 inch drop which is very close to the 1-1/2 inch drop that you need. It should be about perfect since the tongue weight of your trailer will most likely cause the suspension to sag slightly.

    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.
