I ordered a similar drawbar with a 5" rise a few weeks ago, but found that my trailer seemed a tad too high with it. So I ordered this 4" alternative, and —as Goldilocks would say— it is "just right." I would recommend that customers who use etrailer's recommended calculations (measuring the difference between the inside top of the receiver opening to the bottom of the trailer's coupler when level) should then subtract 1" from the result. Why? Because the base of the ball raises the coupler 1" higher than the top of the drawbar. Other than that miscalculation, these drawbars are rock solid, top quality, more than adequate, reasonably priced. 559868

Theres actually two reasons why we dont mention subtracting an addition inch. 1 The rear of the vehicle will sag by a certain amount generally an inch or so when the trailer is hitched up and 2 The trailer doesnt need to be exactly level. As long as youre within an inch or two, youll be just fine.

Bought two hitch mounts and a tie-down strap. Quality of all is outstanding but, even better, the service was fantastic. The three items arrived 2 days after I ordered them. I did not have to pay anything for shipping. Before ordering them I asked a couple online questions and the answers came quickly, within a couple hours. Highly recommend etrailer.com. 458678

Very well made with an attractive finish. I'm sure it will give me years of good service. I was also impressed with how fast (2 days) I received the order. Thanks for the excellent service. 227060

The product was easy to install by watching an installation video on you tube. The product was shipped very quickly. I procrastinated, waiting until two days before my family was to leave on vacation. I noticed that a piece was missing while installing the hitch. The customer service went out of their way to insure that I received the required piece before we left on vacation by finding the closest warehouse to me, and having the piece shipped overnight. They saved me from having to cancel the family vacation and disappointing the family. The hitch was just as described, and well as the installation, and the customer support was of the highest caliber. Mont M. from Hubbard Ohio. 206708

Ask the Experts about this Curt Trailer Hitch Ball Mount

  • Could Curt Ball Mount # C45021 Tow Camper that Weighs 1,395 lb
    The Curt ball mount part # C45021 that you mentioned would have the capacity needed for your camper that weighs 1,395 lbs as it's rated for up to 2,000 lbs but you'll want to make sure this ball mount will provide you with the correct rise/drop that your trailer needs. This ball mount provides 4 inches of rise. I attached an FAQ that details how to pick out the correct ball mount. Picking out the correct ball mount will allow your trailer to sit as level as possible. Basically you will...

  • Thickness of Platform for Hitch Ball on Curt Class I Drawbar
    The thickness of the platform on the Curt Class I Drawbar # C45021 where the hitch ball is installed is about 5/8". I have attached a photo to demonstrate this and you can see this referenced in the attached review video. For a 2" hitch ball you can use part # C40018 or for a 1-7/8" hitch ball you can use part # C40001. If you don't already have a pin and clip the part # F-4 is perfect for this application.

  • 1-1/4" Ball Mount Needed with a 4" Rise
    Although we do not have any adapters that change a 1-1/4" ball mount to a 1" ball mount, we do have a wide selection of ball mounts that you can choose from. Among the linked selection we have the Curt Class I Drawbar # C45021 which has a 4" Rise, is 9" Long, and is rated for 200 lbs Tongue Weight (TW). This is compatible with any hitch ball that has a 3/4" shank like the 1-7/8" Hitch Ball # A-80 or the 2" Hitch Ball # A-82. I have also attached a link to our helpful article on...

  • Drawbar Will Not Fit Trailer Hitch On 2004 John Deere Buck ATV
    The problem you probably are facing is that you have to use a Class l ball mount in the hitch receiver on your John Deere ATV. The shank on a Class ll ball mount is inserted in the receiver more than on a 1-1/4 inch receiver and the holes will not line up. I went to the warehouse and measured the Curt Class l Drawbar, part # C45021. The distance from the end of the shank that goes in the receiver to the center of the hitch pin hole is 1-1/2 inches. This drawbar has a 4-inch rise and...

  • Class I Ball Mount to Allow for Total Hitch Ball Height of 17-Inches on 2014 BMW 428i
    When we installed the Curt Class I hitch # C11367 on a 2014 BMW 4-Series coupe we found that the height of receiver opening was 11-inches above ground level. This is shown in both the linked photo and installation video. Since there are two stock tires sizes offered on the car, P225/50-17 and P255/40-18, the actual height of your vehicle could differ from the one in the video. The recommended Curt Ball Mount is part # C45521 which has 2-5/8-inches of rise and can be used with a ball...

  • Determining Which Drop/Rise Ball Mount will be Needed to Transport my Coleman Popup Camper
    I can help you figure out what which ball mount you will need for your Mazda and Coleman popup camper. There's some specific measurements to take to determine the rise/drop of ball mount you need. Measure from the inside top of the receiver tube to the ground. Then, with the trailer jacked so that it's level, measure the distance from the underside of the coupler to the ground. The difference between the two measurements is the rise/drop needed. If the coupler height is taller than that...

  • Recommended Solution to Carry 4 Bikes on 2017 Mini Cooper 4 Door with Hardtop
    I have a solution for you, but the Curt # C11417 is not a confirmed fit on the 2017 Mini Cooper; it is designed for older models of the Mini Cooper only. The only available hitch confirmed to fit the 2017 Mini Cooper (excluding S and John Cooper Works editions) is the EcoHitch # 306-X7290, which has a 1-1/4" receiver. With that said, this EcoHitch is a Class I hitch with a 100-lbs tongue weight capacity and 1000-lbs towing capacity, so you're not going to be able to use a hitch mounted...

  • Can Two 68 Pound Kayaks be Carried on the Roof of a 2016 Ford Fusion
    The strongest roof rack we carry for your 2016 Ford Fusion maxes out at 125 pounds so it will not be the best option for your 2016 Ford Fusion and two 68 pound kayaks. The components are limited by the capacity of your vehicle as the individual parts are rated higher. I do have a solution for you but none of the available roof racks for your Fusion are rated high enough. The only remaining option is to use what is called a roof rack on wheels.

  • Recommended Ball Mount with 4" Rise for 1-1/4" Hitch
    It sounds like you are looking for a 1-1/4" ball mount which has a 4" rise. If that is the case then I recommend the Curt Drawbar part # C45021 which is the shortest we have available at 9" long. In order to complete this setup you'll need the Hitch Pin/Clip part # F-4 and 2" Hitch Ball part # C40018. The Draw-Tite Drawbar for 1-1/4" Hitches part # 36078 cannot be used in the rise position according to the manufacturer.
