The CURT 45900 Adjustable Channel-Style Ball Mount delivers versatility, strength, and quiet towing in one heavy-duty setup. Designed to fit 2″ x 2″ receiver hitches, this adjustable ball mount features dual permanently mounted hitch balls—2″ and 2-5/16″—allowing you to tow a wide range of trailers without changing hardware.

The channel-style design provides multiple height adjustment positions, letting you fine-tune your setup for proper trailer leveling. With up to 5-1/4″ of rise and 6″ of drop, the CURT 45900 helps keep your trailer level for safer handling and reduced wear. A dual-pin mounting system built into the channel helps minimize rattle and chucking for a smoother, quieter ride.

Built from solid steel and finished in black carbide powder coat, this ball mount offers long-term resistance to rust, scratches, and UV damage. Whether you’re towing utility trailers, equipment, or heavy loads, the CURT 45900 is a reliable, all-around adjustable towing solution.
