CURT Trailer Hitch Ball 1-7/8" Chrome 2,000 lb, 3/4" Shank — Nickel-Chrome Finish, Fine-Thread

CURT 40001 is a 1-7/8-inch chrome trailer hitch ball rated to tow up to 2,000 pounds, built from hot-forged steel with a 3/4" shank and corrosion-resistant finish.

This compact trailer ball is designed to match 1-7/8" couplers used on Class 1 and Class 2 towing setups. CURT engineers these hitch balls to exact tolerances so the stamped diameter reflects the actual size, and the fine-thread shank plus included hex nut and helical lock washer provide a secure attachment to your ball mount. Finished in nickel-chrome plating, the 40001 balances strength, fit, and corrosion resistance for routine towing tasks.
