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

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 458678

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.

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 Ball Mounts
Do you have a question about this Ball Mount?

  • Can Two 68 Pound Kayaks be Carried on the Roof of a 2016 Ford Fusion
  • Rola Rail Extreme DFE Series Roof Rack # R5004 is rated for 110 pounds so it will not be the best option for your 2016 Ford Fusion and two 68 pound kayaks. The bars themselves are rated higher but the mounting feet in this roof rack is limited to 110 pounds. I do have a solution for you but none of the available roof racks for your Fusion are rated higher enough. The only remaining option is to use what is called a roof rack on wheels. This is basically a trailer with a roof rack on...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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).
