I do have an option for you but we don't offer a replacement u-bolt for the Brophy Stabilizer Clamp and U-Bolt for 2" Hitch Receiver part # RSCP. The item is honestly pretty cost effective from the go so even if it were available, a new u-bolt would run you just slightly less than a new assembly and this option gets you new nuts and plate. That said, I think now might be a good time to upgrade to a tool-less design, the Curt Anti-Rattle Hitch Clamp for 2" Hitches part # C27UR. view full answer...
