Rubicon Express, Off Road General Store, Rusty's. I have Rusty's HD trac bar, had the RE one with the heim joint. Joint finally gave up the ghost after 4 years so I switch to the rusty's conversion. All are good. I would say that RE is a thicker bar (beef) than the Rusty's. Rusty's is pretty thin. But it has done it's job. Juice
