Backed by our guaranteed-fit promise.
When your towing demands outmatch ordinary equipment, the CURT Class 4 Ball Mount is engineered to rise to the occasion. Designed with precision and constructed from premium quality steel, this ball mount seamlessly complements CURT Class 4 trailer hitches, making it the ideal choice for towing substantial loads like large boat trailers, RVs, livestock, horse trailers, as well as various industrial or farm trailers.
Note: Always adhere to the lowest weight capacity of any towing component you are using, whether it’s the vehicle, hitch, or trailer.
This robust ball mount features an impressive gross trailer weight capacity of 10,000 lbs. and a tongue weight rating of 1,000 lbs. Options for a 2" standard drop or the ability to flip for a 1" rise ensure precise trailer leveling. Thanks to the hollow shank design, you can employ an anti-rattle hitch pin or lock to minimize noise and vibration during travel.
Our CURT Class 4 Ball Mounts are distinguished by meticulous manufacturing processes: they are CNC-formed, robotically welded, and mechanically descaled for a flawless finish. To further elevate durability, each ball mount is coated in a sleek gloss black powder finish, offering superior rust, chip, and UV resistance.
Made proudly in the USA, the CURT Class 4 Ball Mount comes with a limited lifetime warranty, providing peace of mind with a one-year coverage on finish and parts. Trailer ball and hitch pin sold separately. Equip yourself with the reliability and strength of CURT, a leading name in towing solutions.
