To equip your vehicle with a BulletProof Sway Control System, a mounting point for the sway control bar must be attached to the hitch. The BulletProof Medium Duty Sway Control Dual Ball Mount allows the connection between your hitch and your trailer. It is most useful in reducing sway on large, heavy loads. Made from solid steel, it features a 2" & 2-5/16" dual ball, along with 3/4" mounting plates on either side of the ball mount to allow the option of mounting the sway control system to either side of the trailer or to run two systems. Rated for up to 14,000 pounds of trailer weight and up to 2,000 pounds of tongue weight, it is compatible with all steel Medium Duty BulletProof Hitches?. It features the same black textured powder coat as the BulletProof Hitch? and comes with two corrosion resistant pins and R-clips to secure the ball mount into the channel of the hitch. *Note: Sway control system is sold separately
