With so many different sizes and styles of trailers out there, we knew we could not make just one kind of ball mount to fit them all. The 2” x 2” ball mount line from CURT is as diverse as the types of toys you love to haul with your class 3 or class 4 trailer hitch, from fishing boats, campers and utility trailers to livestock trailers, RVs and recreational vehicle haulers. Whatever your lifestyle, we want you to be able to Bring It® with the right equipment. CURT 2” ball mounts range in towing capacity from 3,500 lbs. all the way up to 17,000 lbs. of gross trailer weight, and each one is precisely engineered and constructed to perfectly fit a 2” x 2” receiver.
