This multi-ball ball mount features a 1-7/8", a 2" and a 2-5/16" ball. The 1-7/8" trailer ball can tow up 3, 500 lbs. of gross trailer weight and 350 lbs. of tongue weight. The 2" ball can handle 5, 000 lbs. of GTW and 500 lbs. of TW, and the 2-5/16" ball accepts loads up to 10, 000 lbs. with 1, 000 lbs. of TW. This multipurpose ball mount also features a dual-length option and has a hollow shank to accept an anti-rattle kit. All of Curt's multi-use ball mounts come with a gloss black powder coat finish and a 2" x 2" shank. CURT multi-tow ball mounts are an obvious choice for anyone who tows more than one trailer on a regular basis. The multiple-ball design allows for quick changes between ball sizes without needing to install or own an entirely different ball mount. Because the balls are permanently welded to the shank, these ball mounts are also very secure, eliminating the possibility of a ball coming loose and deterring any potential theft. | Curt Multi-Ball Mount (2" Hollow Shank, 1-7/8", 2" & 2-5/16" Chrome Balls) #45001
