2-Inch Trailer Hitch Ball with 6,000 lb Rating and 1 x 2-1/8-Inch Shank – CURT 40004 Chrome
2-Inch Trailer Hitch Ball with 6,000 lb Rating and 1 x 2-1/8-Inch Shank – CURT 40004 Chrome
A 2-inch trailer hitch ball provides the coupling point between a compatible ball mount and trailer coupler. CURT 40004 is hot-forged from alloy steel and rated for up to 6,000 pounds gross trailer weight, supporting utility, boat, camper and recreational trailers within the complete towing system’s limits.
The fine-threaded shank measures 1 inch in diameter and 2 1/8 inches long, with a zinc-plated hex nut and helical lock washer included for installation. Chrome plating helps resist rain, road dirt, rust and scratching, while the zero-rise geometry keeps the ball centered on its mount. Fit it only to a 2-inch coupler and a mount with the correct shank hole and thickness. Tighten the nut to the documented 250 lb-ft and never exceed the lowest rated component among the tow vehicle, receiver, mount, ball, coupler and trailer.
