The information provided is for general informational purposes only.For multiple types of towing, we here at CURT want to supply you with products that make things easier and more efficient. After all, towing that boat, camper or recreational vehicle trailer is all about doing more of what you love. CURT dual length ball mounts offer a fast way to adjust your towing equipment to fit your trailer or hitch-mounted accessory. Rather than buying a second ball mount to accommodate two types of trailers or installing a receiver extender, the dual length ball mount offers a better way. With two holes in its shank, the CURT dual length ball mount can be lengthened or shortened in a moment's notice. If you have a trailer or bike rack that requires a little extra clearance from the vehicle's bumper or spare tire, the dual length ball mount can be extended by simply removing the pin and clip and pulling it out to the second hole. When you need the trailer snug up to your vehicle, the ball mount can then be moved back to its original position. CURT dual length ball mounts are made with quality steel and are robotically welded for precision. This particular ball mount offers a gross trailer weight capacity of 7,500 lbs. and a tongue weight rating of 750 lbs., making it an excellent choice for your class 3 trailer hitch. It can be used at a length of 8-1/8" or 11-1/8". It also features a drop of 4", a rise of 2" and a durable gloss black powder coat to protect it from rust, scratches and harmful UV rays. CURT offers custom trailer hitches, electrical products and a complete line of towing accessories to get you there with confidence and enjoy every mile of the journey. There are three main things to consider when selecting a trailer hitch ball mount: how much weight you are going to be towing, what size receiver tube your trailer hitch has and how much drop or rise your ball mount will need (below). First, be sure to select a ball mount with enough gross trailer weight capacity to fit your trailer. Trailer weight is one of the most important aspects of towing, and you should never exceed the weight capacity of any component of your vehicle, trailer or trailer hitch setup. Next, determine what size shank you will need. Receiver tubes come in a handful of standard sizes, including 1-1/4, 2, 2-1/2 and sometimes 3 inches, so finding a ball mount to match is relatively easy. After you know how much weight you will be towing and the size of your receiver tube, you will need to determine the drop or rise necessary for your trailer. Drop or rise is the amount of height difference between the trailer and your tow vehicle, whether that difference is positive (rise) or negative (drop). The diagram offers a quick explanation for how to determine your needed drop or rise. Take the distance from the ground to the top of the inside of your receiver tube opening (A), and subtract it from the distance from the ground to the bottom of the trailer coupler (B). B minus A equals C, the drop or rise.
