Video Transcript for Curt Hitch Ball - Trailer Hitch Ball - C40018 Review

Today were going to take a look at the Curt 2-inch hitch ball, part number C40018. This chrome hitch ball has a 2-inch diameter. It has a shank diameter of of an inch. It has a shank length of 2 1/8 of an inch. It fits a ball mount with a drawbar thickness of 3/8 of an inch to 5/8 of an inch, and it has a weight capacity of 3,500 pounds. Were going to bring in our ball mount with our trailer hitch demonstrator here and show you how this would be installed.

First you just slide the shank into the ball hole. Youll take the nut and washer which are included with this item, slide the washer up there, and then you will finger tighten the nut on there. Once you have that tightened as far as it will go youll then take your wrench and you can get some extra leverage using the wrench flats on the hitch ball, and then you would tighten that fully to use with your trailer and your coupler. That should do it for our Curt 2-inch trailer hitch ball, part number C40018.

This takes up some of the gap between the two different sizes of receiver and attachment. As you increase length of an attachment, the outermost edge of the attachment can get close to ground level; taking up even a part of the gap between receiver and attachment helps... Thanks... 754807

Ask the Experts about this Curt Hitch Ball

  • Can 5 x 8 Utility Trailer be Towed Using Hitch Ball on Truck Bumper
    You might be able to tow a small 5x8 utility trailer using a hitch ball mounted to the bumper of your truck but this will depend on how heavy the loaded trailer is along with the specific bumper capacity of your vehicle. If you can tell me the year, make, and model of your truck I will be happy to try and look this up, otherwise this information should be listed in your owner's manual. Based on my research a standard 5 x 8 utility trailer from U Haul has a gross vehicle weight of 2,700...

  • Trailer Hitch, Wiring, and Brake Controller to Tow 1,500 Pound Trailer with 2010 Subaru Forester
    The 2010 Subaru Forester is rated for 2,400 pounds gross trailer weight as long as the trailer has brakes. If the trailer does not have brakes it is limited to 1,000 pounds. For a trailer hitch that will cover the towing capacity of the vehicle you can indeed use # C12047. The recommended ball mount is # C45521 along with the pin and clip # F-4. For a 2 inch ball you can use # C40018. You will also need a trailer wiring harness on your Forester. If the trailer has electric brakes...

  • How to Know Which Ball Mount and Hitch Ball to Use
    The hitch ball you need will depend on the size the trailer's coupler connects to; it will likely be a 1-7/8" ball or 2" ball. As for the ball mount, there is a simple way for you to determine if you need drop or rise with a couple measurements. First, make sure both your vehicle and trailer are parked on level ground; you'll then want to measure from the ground to the top of the inside of your hitch receiver. Next, measure from the ground to the bottom of your trailer's coupler. If...

  • Ball Mount And Hitch Ball For Curt Class ll Trailer Hitch On 2014 Toyota RAV4
    To find the right ball mount you need to tow your Coleman Popup Camper level you can take a couple of quick measurements. Park the trailer and your RAV 4 on level ground. Measure from the top of the trailer receiver opening to the ground. Then measure from the ground to the bottom of the coupler on your trailer. If the hitch height is greater you need a ball mount with a drop. If the trailer coupler height is greater you need a ball mount with a rise. Take a look at your trailer coupler...

  • Is Curt 2" Hitch Ball Compatible With Class II Drawbar 45521
    I am happy to confirm that yes, you can use the Curt Chrome 2" Hitch Ball # C40018 you asked about with the Curt Class II Drawbar # C45521. These two parts are completely compatible, and also keep in mind you will need either a pin and clip or hitch lock to secure the ball mount to your hitch receiver. For that you will need either Curt Class I and II Pin and Clip # F-4 or Curt Trailer Hitch Receiver Lock # C23517. I have added links to some video reviews for you to check out as well.

    The available 1-1/4-inch Class I hitch options for your 2019 Jetta include the Curt round tube hitch # C11540 and the Draw-Tite model # 24978. The Curt offers easier installation but its cross tube will be visible under the bumper cover. The Draw-Tite hitch installation requires removal of the entire bumper fascia and the bumper itself but gives you a much more discrete appearance once installed. The linked photo shows the Draw-Tite hitch. Both hitches include all of the required mounting...

As of right now we only carry one wiring harness for your Trax, the Tekonsha # 118751. It plugs into a factory connector that's in your rear cargo area under the floor cover and some interior paneling. Then you'll need to run a wire to the Trax's battery through the included fuse holder. The fuse is included as well. This harness...

  • Recommended Trailer Hitch and Wiring for 2018 Hyundai Tucson Sel Plus
    When we research towing capacities we base it off of what the owner's manual says but for some unknown reason there are no online manuals available for a 2018 Hyundai Tucson. I did take a look at the Hyundai website and as you said it listed the SEL Plus as having a 2,000 lb towing capacity as opposed to the 1,500 lb capacity of the SE and SEL; however, it looks like the SEL Plus only has some interior features differentiating it from the SE and SEL so it would not make sense for the capacity...

  • Can a 2015 Dodge Dart Carry a Motorcycle on a Hitch Mounted Motorcycle Carrier
    With that being said I definitely recommend not carrying your Honda motorcycle with your 2015 Dodge Dart. The carrier you're looking at, part # MT70101, is rated up to 400 pounds and from my research the bike has wet weight of 357 pounds. So I understand why you think you're okay. However, you're capacity is limited by the lowest rated component, and the Curt hitch, part # C11281, is a Class I hitch that's rated up to 200 pounds of tongue weight. Furthermore, your 2015 Dodge Dart is...

Since there are four different versions of the 2017 VW Jetta (the S, SE, SEL and GLI) to confirm your model's towing capacity you need to check your printed manual.

  • Best Trailer Wiring Harness Option for 2004 BMW 325xi Sedan
    Since there isn't a plug and play option for your 2004 BMW 325xi Sedan, the best option and the one I recommend is the ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT. What sets this harness apart from others is that it uses sensors that clamp onto your vehicle's tail light wires to sense the current and transfer it back to the trailer connector. This means you don't have to worry about any potential issues caused by cutting or splicing into your BMW's factory wiring. The built...

  • Correct Ball Mount Recommendation to Tow Malone XtraLight Trailer with PT Cruiser and Curt Hitch
    You asked a great question about picking out the correct rise/drop ball mount for towing the Malone XtraLight Trailer part # MPG525G. Basically you want to go with the ball mount that has the correct rise/drop to allow the trailer to sit as level as possible. So when the Curt hitch part # C11132 is installed on your 2010 Chrysler PT Cruiser it's going to have a distance of 11-1/4 inches from the top of the hitch opening down to the ground and the Malone trailer has a distance of 15 inches...

  • Difficulty of Installing a Trailer Hitch on a 2012 Audi A3
    Installation of Curt trailer hitch # C11192 on your 2012 Audi A3 requires some drilling, bumper removal, fascia trimming, and removal of spare tire and tail lights. None of this is all that difficult, it just takes time. To determine if this is something you want to tackle you can take a look at the video I have linked showing an installation. I have also linked the instructions for you. You might not need to buy a torque wrench. Most auto parts stores will loan out tools. If you...

  • Can I Tow a Malone MicroSport Trailer with a Nissan Altima
    What that means is that the Malone MicroSport trailer, part # MPG460G, is level when the bottom of the coupler is 18 inches off the ground. To tow the trailer level you need a ball mount with a rise. Park your Nissan Altima on level ground and measure from the ground the inner top of the receiver hitch. When we installed the Draw-Tite hitch on an Altima we measured 10-1/4 inches. You'll likely be close to this but measure your car so you're sure. Then subtract your measurement from...

    The Curt Class II hitch part # C12111 that fits your 2017 Ford Escape would be a really solid choice for your application. It has towing capacities of 3,500 lb trailer weight so it would easily handle the weight of your ATVs and lawn mower. I attached an install video for you to check out as well. For a ball mount you'd want the # C45518 with hitch ball part # C40018 for a 2 inch ball or part # C40001 for a 1-7/8 inch ball. Then for trailer wiring the # 118715 is an easy to install...

I get the same options when I type this into Curt's fit guide. I'm not sure if we had a glitch or what, but I am confident that either of these hitches I referenced will work well for you.

  • Tallest Rise 1-1/4 inch Hitch Ball Mount Availability
    When measuring for ball mount rise/drop needed you have to measure from the bottom lip of the coupler to the ground and not from the top like you mentioned. That means your trailer height is going to be more like 20 inches instead of 22 inches. That being said the closest ball mount we offer to what you need is going to be the part # C45028 which can do a rise of 5-3/8 inches. Then for a 2 inch ball you would want the part # C40018.
