RBM billet shift shafts are machined, heat treated, centerless ground and then coated with an anti-slip coating to ensure trouble-free shifting for your engine.
Most others grind, then heat treat their shafts. This causes up to a .005" out of roundness that will reduce shifting smoothness. These are the only shafts that are ground after heat treating, and then coated with a true anti-slip coating.
