CURT Trailer Hitch Ball 1-7/8" Chrome — 2,000 lb Capacity, 3/4" Shank

CURT 40001 is a 1-7/8-inch chrome trailer hitch ball built from hot-forged steel and rated to tow up to 2,000 pounds when installed with compatible towing components.

This compact tow ball is designed to pair with class 1 and class 2 hitch assemblies and standard 1-7/8" couplers. CURT machines the ball diameter to exact tolerances so a stamped 1-7/8" corresponds to the real contact surface, and the nickel-chrome finish helps resist corrosion and road wear. The shank uses fine threads and includes a zinc-plated hex nut and helical lock washer for a secure, long-lasting connection to a ball mount.

Will this hitch ball fit my trailer coupler?

The CURT 40001 is sized specifically for 1-7/8" couplers; check the stamped size on your trailer coupler or measure the inside of the coupler throat. Ensure your ball mount accepts a 3/4" shank and that the 1-5/8" shank length provides enough thread engagement with the mount.

• Ball diameter: 1-7/8" — matches most 1-7/8" couplers.
• Shank diameter: 3/4" — fits mounts drilled for 3/4" shanks.
• Shank length: 1-5/8" — secure thread engagement with included hardware.
• Fine threads and hex nut — improved holding strength.

How much weight can I tow with this ball?
