Review on CURT 40003 Chrome Trailer Diameter by Ashutosh Takumatla

Chrome plating seems only a few atoms thick. It's pathetic and wore out after a 10 mile tow of a 500 pound trailer. UPDATE: The chrome is still wearing away - through the copper in some places. These are not quality balls. And I don't even expose them to salt water! Imagine how bad the corrosion would be in a real marine environment. I would regret buying it if it weren't so cheap. Maybe I'll regret it later when I have to cut it off my clutch with a grinding wheel.
