Curt Manufacturing 40067 Trailer Ball 1" x 2-1/8" Shank Chrome 2-5/16

Ball and shank dimensions

The CURT 40067 trailer ball uses a 1" shank diameter and a 2-1/8" shank length with a 2-5/16" ball diameter. It is built for towing setups that require this specific ball size and shank combination. The chrome finish helps resist corrosion during regular use. This component suits owners matching existing coupler and mount specifications.

Coupler and mount compatibility

Verify that your trailer coupler accepts a 2-5/16" ball before ordering. Confirm the ball mount or drawbar has a 1" mounting hole and sufficient thickness for the 2-1/8" shank length. Check the gross trailer weight rating of the ball, mount and hitch to ensure the complete assembly meets your load requirements. Missing any of these checks can create an unsafe connection.

Chrome finish and daily use

The chrome plating provides a hard surface that resists rust and simplifies cleaning after exposure to road salt or moisture. A smooth ball surface reduces wear on the coupler latch and allows consistent pivoting during turns. The shank length accommodates standard ball mounts without excessive protrusion. Regular inspection of the ball surface and mounting hardware maintains reliable towing performance.
