I have a custom made tow guard. The ball mount I have was too short to allow me to attach the tow guard to my new truck. I searched the web and found just what I needed at etrailer.com. It's the only site I found that carried the size I needed. The product fits my needs perfectly. I can now protect my boat from rocks and other road debris when towing. Thank you etrailer.com. 296129

I purchased this unit to extend the trailer jack handle just far enough that I could open the tailgate on my truck with the trailer attached. It worked perfect. I tow a pop-up camper with 2006 Toyota Tacoma. Pricing was good and delivery was quick from etrailer. At first I tried to buy locally from auto parts store or camper store, but neither had in stock anything the right dimensions. The unit from etrailer is made in the USA, fit just right, and was better quality than what I saw locally. 262998

With good information from the website it was easy to order a Curt 2" Trailer Hitch, the Upgraded Circuit Protected Tail Light Converter Hardwire Kit w/ 4-Pole Connector and Circuit Tester - 119178KIT, Curt Ball Mount for 2" Hitches (3/4" Rise, 2" Drop - 10-1/4" Long - 7,500 lbs - D-4), Curt Pin and Clip Hitch Receiver - C21500, Rubber Tube Cover for 2" Trailer Hitch Receivers - I-728,Review, and 2" hitch ball 40038. Parts were delivered earlier than the initial estimate. Self installation (on a sloped drive way) took just under 2 hour. The fit of parts was very good, instructions and on-line video's were very helpful. My Kia did not have the wire plug in option, but the splice connections in the wire kit were easy to install. Most of the parts are hidden from view when the ball mount is not used. 718951

Great fast service. The new one I purchased is a 10-1/4" long. My original was 8-1/2". I have a travel trailer and had a heck of a time turning with the 8-1/2". The new 10-1/4" made all the difference. I can turn the trailer without any issues. It has the same rating as my 8-1/2" also. Works great. 567199

This is the 10th order I have made from etrailer.com, most of them with multiple items. I cannot say enough about what great experiences I have had with etrailer.com. The website is incredibly helpful, the search tools are great, and the specs, videos and other information are very helpful. The items always ship right away, and arrive well packaged and promptly - and for me they have to cross the border to Canada. I recommend this site to my friends with trailers and I would recommend it to anyone who wants a great experience - and who doesn’t! 465802

Ask the Experts about this Curt Trailer Hitch Ball Mount

  • What do you Recommend for a Class 3 Cushioned Ball Mount Rated for 7,500 lbs. Without a Rise
    I have two really good options for you that offer a zero rise. The Draw-Tite 2-Ball Mount for 2" Hitches part # 80796 has both a 2" and a 2 5/16" ball and is rated for up to 16.000 lbs. It does not have the cushioned feature you asked about but gets the job done. For the shock absorption you want the Gen-Y Torsion 2-Ball Mount w/ Stacked Receivers part # 325-GH-1024 this also has the 2 and 2 5/16" balls and is perfectly suited for your trailer and tongue weight assuming it is 10-15%...

  • Does Ball Mount Have To Place Trailer Ball Exactly Level
    You will want to choose a ball mount that will place the trailer ball at the appropriate level so that your trailer is towed level, or within 1-1/2 inches plus or minus either way. The ball mount you reference, # D-4, has a rise of 3/4 inch so it should work well for your application. I have included a FAQ article on choosing the correct ball mount for you to check out.

  • How to Get a Ball Mount with 0 inches of Rise or Drop
    In order to get a ball mount that has effectively 0 inches of rise or drop you would need to get a Trailer Hitch Ball Mount, part # D-4, like the one you referenced that has a 2 inch drop, and then use a 2 Inch High Rise Ball, part # C40034. I attached links to FAQ articles on ball mounts and hitch balls below for you to check out also.

  • How to Order a Ball Mount for 0 inches of Rise/Drop
    You are correct, you do need a zero rise/drop setup to tow your trailer level. In order to get a ball mount that has effectively 0 inches of rise or drop you would need to get a Trailer Hitch Ball Mount, part # D-4, like the one you referenced that has a 2 inch drop, and then use a 2 Inch High Rise Ball, part # C40034. Otherwise none of our ball mounts are designed for an exact 0 rise/drop.

  • How Long is CURT Ball Mount # D-4 Versus a Standard Length Ball Mount
    The ball mount is 10-1/4 inches long from the center of the hitch pin hole to the center of ball hole, approximately 2 inches longer than what most consider as a standard length. If you are looking for something that is very long, take a look at # 80232, which is 16 inches long from hitch pin hole center to ball hole center. Or, if you need a specific length, I have included a link to our ball mount main page for you. I have also included a link to our ball mount FAQ.

  • Hitch Ball Recommendation for Curt D-4 Trailer Hitch Ball Mount
    You will need a ball that matches your trailer coupler. The required ball size should be stamped into the top of the coupler. For a 1-7/8 inch ball you will want hitch ball # 19261. For a 2 inch ball you will want # 63849. For a 2-5/16 inch ball you will want # C40007. I have included a FAQ article on choosing hitch balls for you to check out.

  • Recommended Ball Mount That Will Work With Shank Mounted Bike Rack
    The Curt Ball Mount, part # D-4 measures 10-1/4 inches from the center of the hitch pin hole to the center of the hole for the hitch ball as you mentioned. Since you said you need at least 6 inches, this ball mount would give you more than enough clearance for your bike rack. This ball mount fits 2 inch receiver openings and uses a hitch ball with a 1 inch shank like part # 40038 for a 2 inch diameter ball or part # C40051 for a 1-7/8 inch ball. If you need a hitch pin and clip...

    We offer two trailer hitches that are compatible with your 2004 Lexus RX330 and both hitches are Class III hitches that will provide plenty of support to carry a bike rack and bikes. Our most economical option is the Curt Round Tube Hitch, part # 13530. We also offer the Draw-Tite Trailer Hitch, part # 75153. Both hitches have a tongue weight of 350 lbs and a gross towing weight of 3500 lbs, but these ratings can be limited by the towing capacity of your vehicle. You will want to check...

  • Recommended Trailer Hitch For Allego 35 Ft Motorhome To Tow Enclosed Trailer
    A tow bar system like the Blue Ox, part # BX7380 is used for flat towing a vehicle behind an RV, motorhome, or another vehicle. Since you said you are hauling an enclosed trailer, you will first need a trailer hitch on your Allegra. I recommend a trailer hitch like the Curt Adjustable Width Trailer Hitch Receiver, part # 13703. This hitch will work on motorhome or RV box frames, C-channel frames or I-beam frames from 22 inches to 72 inches wide. This hitch can be bolted to the frame...

  • Will Longer Ball Mount Increase Turning Clearance for Small Trailer When Backing Up?
    Having an extended ball mount will help with giving you some additional clearance simply because it moves the pivot point back which changes your clearance at the outer edges. The Curt # D-4 is similar with 10-1/4 inch measurement. You may want to consider the Ball Mount 3/4" Rise or 2" Drop, Extra Long # D-26 which is 12-5/8" from hitch pin center to ball center. Then you will need a hitch pin like # C21500 and hitch ball like # 63845

  • Ball Mount Recommendation For Use with Curt Clamp-On 3 Bike Towing Rack
    It looks like you previously ordered the Draw-Tite Ball Mount 3/4 Inch Rise or 2 Inch Drop, 7,500 Pounds # 2923. Another great option for a ball mount with the same rise, drop, hitch ball shank size, and towing capacity is the Curt Trailer Hitch Ball Mount 3/4 Inch Rise or 2 Inch Drop # D-4. The measurement from the center of the pin hole to the center of the ball hole on the Draw-Tite ball mount you own is 8-1/2 inches. The Curt ball mount measures 10-1/4 inches from the center of...

  • Correct Ball Mount for 2002 Ford Explorer Towing Trailer with 20 Inch Coupler Height
    Based on those measurements you would need a ball mount with a 1/2 inch drop, but because a ball mount with that drop is not available, you will need to choose one that gets you as close as possible. As long as the ball and the coupler are within 1-1/2 to 2 inches of level, you would certainly be close enough. Given the choice, it is better to have the ball a bit higher than the coupler. If you were to use the # 2923 ballmount in the rise position, your hitch ball height would be...

  • 2 Inch Ball Mount Recommendation for a 2011 Toyota 4Runner Towing a 19 ft Boat Trailer
    When measuring for the correct drop or rise in a ball mount, you will actually want to measure from the ground to the bottom of the trailer coupler. Most trailer couplers are only about 2 inches tall at the ball socket, so the measurement you have is likely around 17-3/4 inches. For this, you will want a ball mount with a 2 inch drop like the Draw-Tite Ball Mount, # 2923. I have attached a video review of this ball mount on a 2012 Toyota 4Runner and a help article that explains how...

  • Long Ball Mount Recommendation for a 2011 Suzuki Grand Vitara and 2013 Rockwood A122S
    For your 2011 Suzuki Grand Vitara and Curt hitch # C13001 you can use any ball mount rated for a Class III, 2 inch trailer hitch. The recommended ball mount for the hitch and vehicle is # 2923 and it measures 8-1/2 inches from the center of the hitch pin hole to the center of the ball hole. For a longer ball mount with the same 3/4 inch rise and 2 inch drop you can go with # D-4 which measures 10-1/4 inches long. Ball mount # D-26 is 12-5/8 inches long. And finally there is # 80232 which...

  • Can Longer Ball Mount be Used to Attach Ball Mount Mudflaps on a 2011 GMC Acadia
    Yes, you can use a longer ball mount on your 2011 GMC Acadia Class III hitch to add the mudflaps. The standard ball mount that we show that is recommended for your Acadia is the Draw-Tite Ball Mount, part # 2923. This ball mount has a 3/4 inch rise or a 2 inch drop. It measures 8-1/2 inches from the center of the hitch pin hole to the center of the ball hole. It has a 6,000-lb gross towing weight capacity and a 600-lb tongue weight capacity.

  • Which Trailer Hitch For a 2007 Toyota Sienna LE will Give Me the Most Ground Clearance
    All hitches that are made for the 2007 Toyota Sienna LE are designed to sit just below the rear bumper and are all close enough in ground clearance that it would not make a noticeable difference which one you picked. On the hitches we have installed we have found that from the ground to the top of the receiver opening is approximately 11 inches.

  • Will The Buyers Products Black Receiver Tube 6 Receiver Tube Extend The Receiver 6
    The Buyers Products Black Receiver # 337RT25806B steel tube is 6" and is a weld on receiver for doing your own fabrication but not an extender. We do have longer weld on receivers like # 325-GH-003 also. If you are looking to extend the length of your existing receiver, there are hitch extenders like # 80307 but these are not ideal if you're looking to tow as these will reduce your capacity. A longer ball mount like the # D-4 is a better option because your full hitch capacity is maintained....

  • Long and Short Ball Mount Options for a 2012 Toyota RAV4 Towing a Boat and Boat Trailer
    From the center of the hitch pin hole to the center of the ball hole on ball mount # 2923 it measures 8-1/2 inches. This should put the ball about flush with the back of the spare tire on a 2012 Toyota RAV4 based on installations we have done. Measure your specific vehicle to be certain. Boat trailers generally have a coupler at the end of a long pole tongue. And the shape of most boats combined with the pole tongue would allow you to easily make turns without any interference issues....

  • Ball Mount Recommendation for Use with a Draw-Tite # 75673 on a 2010 Subaru Outback Wagon
    There is not a required ball mount for this Draw-Tite Trailer Hitch Receiver, part # 75673. Since you are worried about clearance I would recommend you use a Trailer Hitch Ball Mount, part # D-4. This ball mount has a distance of 10-1/4 inches from the center of the hitch pin hole to the ball hole. You would have plenty of clearance to run this ball mount in the rise position. I attached installation instructions below as well as a review video of this hitch for you to check out.
