Does your 58-66 fleetside tailgate rattle around? Does it feel like it hangs up while opening or closing it? The factory design is a metal hinge with a metal tailgate. This constant contact will wear down the hinges and cause them to rust. Urethane hinges for stepsides have been around for years so Brothers trucks set out to fix this issue for the 1958-66 fleetside trucks. We designed a high quality cnc machine delrin ring around a zinc core. This core is then mounted to your stock steel bracket to allow an easy, bolt-in installation. No need to lubricate your old hinges anymore with Brothers exclusive design. Sold in pairs.
