Curt heavy-duty welded ball mounts are the pinnacle of the receiver-style ball mount design. They are built from CNC-formed steel and are robotically welded to be strong, clean and precisely fitted. These ball mounts have the towing power to match our Class 5 hitch line, offering a gross trailer weight capacity of 15,000 lb and a tongue weight capacity of 1,500 lb. This makes the heavy-duty ball mount a perfect fit for the heaviest trailers to hit the road, including small yacht trailers, double-axle utility trailers, toy haulers, car haulers, RVs and more. This particular Curt heavy-duty ball mount comes with 8 in of drop, 6-1/4 in of rise and has a length of 10-1/2 in. It is equipped with a 1-1/4 in trailer ball hole and features a 2-1/2 x 2-1/2 in shank. To keep our Class 5 ball mounts well protected, we coat each one in a durable gloss black powder coat finish. This makes them rust-resistant, scratch-resistant and UV-resistant for a long-lasting towing solution. No matter where you find yourself every day the construction site, the industrial park or the open fields when you need towing equipment that will work as hard as you do on the job, trust Curt heavy-duty. Our Class 5 ball mounts are tough as nails to make heavy-duty towing look easy. They are the perfect complement for your full-size pickup, SUV, flatbed or other commercial truck.
