Corrosion-resistant ball mount is 9-1/2" long and fits 1-1/4" x 1-1/4" trailer hitch receivers. Ball mount can be used in the rise position only.


Very easy to install, looks good and functions well. I would buy it again.


Fits my Curt hitch as described (also purchased from eTrailer), but if pushed in too far it gets stuck in the receiver tube. Had to use a wheel puller to get it back out! Just need to push it in an inch or so to the pin holes line up not problem. My only complaint about ETrailer is that they use huge staples to close their shipping boxes. The staples are tough to pull out (get out your screw driver and pliers if you don't have an industrial strength commercial staple puller). My cardboard recycler does not want these dangerous looking staples left in the box, so I need to pull every one of them out!


All the items in my order arrived today. Thanks for your continued follow-up on this order and the speedy shipping once you had the item on hand. I also appreciated the installation video and pictures on etrailer. com. I routinely recommend that my customers reference your website for install instructions and product explanation videos. Keep up the good worK.


Very fast delivery, Very low price for this sturdy drawbar... fits my Rav 4 Class II hitch perfectly.

Have used the ball hitch to pull my Australian Kamparoo all over the country- no problems!Thanks,
Steve D - 08/31/2016


The draw bar was a perfect fit for the car. The price was very competitive and the delivery was fast.

Perfect, as designed.
Lennox C - 09/28/2017


Is very solid and fits perfectly into the 1 1/4 inch receiver. I and really surprised that it didn't come with a pin though


All stock on this ball mount is solid steel, making it heavier than most class II draw bars. It has a nice finish and good welds.


Great product - just the right amount of rise for my little trailer!

Product still going strong!
Alexander K - 06/15/2017


Let me just say that is the best in the business.
Great experience. The Web site is very user friendly and
thorough providing guidance each step of the way.
Also Personnel are well informed and most helpful.
Thank you,
Paul L


Received the product much quicker than expected. Paid the minimum shipping charge. Well packaged. Some chips on the black powder coating, but, that's not really an issue for me. It fits well and appears to be a quality made item. Will be used on a 2013 Avalon for towing an 800 lb. teardrop camper. I will not know details until I actually get a chance to use it later this year. I will make a follow up review later on the year.
So far so good!!


Delivery was as expected and item is exactly what I was looking for. The elangation and height is perfect, and it should easy hooking up the trailer and protecting rear bumper.


Receiver fit my 2004 VW Beetle perfectly, shipping was fast too A+ service thanks!!!


Easy to install and very strong. Now I can pull a trailer with my Audi. Very happy.


I have UTV and has Class II hitch,so it's for that.


Works great! Perfectly lift amount for my lowered car . (2001 Audi tt) Easy install. Never had a problem. Thanks guys


Great product, excellent construction. Fit the way I needed it to tow a trailer behind my GoldWing Trike.


Worked as advertised, installed easily. Very sturdy as well.


Product was good as advertised. There was a problem getting the item, probably caused by UPS, but when notified, dealer was prompt to remedy it.
I can endorse this company without reservation.


Hitch was received when expected and fit. No complaints. I will purchase from etrailer again.


Delivery was quick.
And it fit like
a glove and was easy to install.


Fits 1 1/4" receiver and has 3/4" hole for pin or ball and just barely clears the bumper.


It works perfectly for my application, very happy with it.


Very nice design, Quick delivery, Very happy with seller interaction. Thanks for great service and product.


Great deal. Half the price of others I looked at.
Happy that I can use it up or down.


Excellent product and great customer service

  • Which Will have Better Ground Clearance Ball Mount C45510 or Euro Drawbar C45591
    Curt Class II ball mount # C45510 will actually be a little better with ground clearance compared to Euro drawbar # C45591 because it doesn't stick out as far and does not have as much of the steel shank below the ball.

  • Class I Trailer Hitch that Fits 2005 Volkswagen Jetta Wagon
    For your 2005 Volkswagen Jetta Wagon we have the Curt Class I hitch part # C11083 which is a confirmed fit and would work well. If you needed trailer wiring too the correct kit is the part # C59236. For a ball mount part # C45510 and hitch ball # C40018.

  • Hitch Recommendation for a 2004 Volkswagen Golf to Tow Small Camper
    The Curt Hitch part # C11066 that you referenced has been confirmed as a fit for your 2004 Volkswagen Golf GTI. The hitch itself has the towing capacities of 2,000 lbs trailer weight and 200 lbs tongue weight. As long as your trailer stays under this figure and the towing capacities that are listed for your vehicle in the owners manual you would be good to go. To complete your towing setup you may also be interested in purchasing the following: Draw-Tite Wiring # 119178KIT (installation...

  • Is There a Trailer Hitch Available for 2004 Audi TT
    We have a hitch for the Quattro models of the 2004 Audi TT. For that you'd want the part # C11765. This has a towing capacity of 2,000 lbs which should easily tow a small trailer with your bike you mentioned but you need to verify that your vehicle has the needed towing capacity in the owners manual. For trailer wiring you'd then want the pat # 119250KIT. For a ball mount you'd then want the part # C45510, and hitch ball part # C40001 for a 1-7/8 inch ball. We are near St. Louis, MO.

  • Recommended Trailer Hitch for a 2001 Honda S2000 to Tow a Motorcycle or Jetski
    Currently, there is one hitch that is a confirmed fit for your 2001 Honda S2000. It's the Curt Class-I trailer hitch # C11212 and has a tongue weight of 200 pounds and gross trailer weight of 2,000 pounds. Even though drilling is required to install this hitch, it will be pretty easy. I attached a link to the installation instructions. Since you will be doing some light duty towing, the wiring kit you need is # C59236. The kit adapts turn and stop lights (3-wire system) to a 2-wire system...

    Yes, installation instructions for Curt trailer hitch # C11212 are linked on its product page, right hand side of the page. I have also included a link to them here for you. This is a Class I hitch so if you are using it for a bike rack you are limited to 2 bikes at most and any accessory used has to be compatible with a Class I hitch. Also with Curt if you are using the hitch for anything other than a trailer you also have to use stabilization strap # 18050 per Curt's warranty requirements. If...

  • Trailer Hitch Fit for 2002 BMW 325i Sedan
    The Curt Class I Receiver Hitch # C11174 has a towing capacity up to 2,000 pounds. However, I was unable to find a towing capacity for your 2002 BMW 325i. Your best bet will be to consult your local BMW dealership to find you vehicle's towing capacity. If you determine that your BMW is capable of towing the cargo you are wanting to tow, the Curt hitch # C11174 will work great for you. The drawbar that is recommended for use with this hitch is the # C45510. For a 2 inch diameter hitch...

    The Curt Trailer Hitch Receiver # C11174 is confirmed to fit a 2005 BMW 3 Series as long as your car is not a convertible. If you have a convertible we do not have a hitch that is confirmed to fit. This is a Class I hitch rated for 2,000 pound maximum towing weight and 200 pounds maximum tongue weight. It's a custom designed bolt-on hitch and does include a pin and clip. You should know, Curt does require using a support strap, part # 18050, if you're carrying any non-trailer loads...

  • Can the Curt Trailer Hitch Receiver C11079 Be Used To Tow a Trailer with a 2002 VW Cabrio GLX
    For a trailer hitch that is a confirmed fit for your 2002 Volkswagen Cabrio, I recommend the Curt Trailer Hitch Receiver part # C11079. This trailer hitch has a 2,000 lb gross trailer weight and 200 lb tongue weight rating. Therefore, you would need to tow the motorbike instead of carrying it on the hitch. In order to complete your towing setup you will also need a trailer wiring harness, the Curt Circuit Protected Converter part # C56175, a ball mount, the Curt Class II Drawbar part #...

  • Trailer Hitch Fit Recommendation for 2007 BMW 530xi Wagon
    For your 2007 BMW 530xi Wagon we have the Curt Class I hitch part # C11498 which is a confirmed fit and will work well. The # C19031 would not fit so you would not be able to use it. For a ball mount you'd then want the part # C45510, for a hitch ball # C40018 for a 2 inch ball or part # C40001 for a 1-7/8 inch. For trailer wiring you'd need the universal install kit part # C59236 which has been tested as fitting your vehicle.

The hitch you referenced, # C11771, fits the 2006 325xi Sports Wagon, not a 2003. If you plan on doing some towing the correct ball mount is # C45510 and you can use pin and clip # PC2.

    You are correct, the Curt Trailer Hitch Receiver # C11498 is designed specifically for the 2006 and 2007 model years of the BMW 530xi Wagon. You are also correct that the Curt # C45510 is the recommended ball mount for the 5 Series wheher you have the sedan or the wagon. In addition, the hitch balls to fit the ball mount require a 3/4 inch shaft like # C40018 for a 2 inch ball or # C40001 for a 1-7/8 inch ball.

  • 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...
