Does your fleetside tailgate rattle around? Does it feel like it hangs up when opening or closing it? The factory design is a metal hinge with a metal tailgate. The 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. We settled on a high quality CNC machined Delrin ring around a zinc core. This core is then mounted to a stainless steel bracket to allow an easy, bolt-in installation. No need to lubricate your old hinges anymore with Brothers EXCLUSIVE design. Sold in pairs.
