You can't go wrong with this plain cast aluminum throttle pedal. Splined pivot hub allows easy indexing of arm for use in nearly any vehicle.NotesThe arm on the side with the small set screw (1.5 mm) is splined to the central shaft. This allows the installer to tailor the arm/pedal angle to suit their installation. The countersunk capscrew (4 mm) which retains the side arm is installed at the factory with a small impact tool and can be quite tight. A palm-sized (or butterfly) impact wrench, or an allen wrench with a longer handle than is provided with the gas pedal, may be needed to remove this retaining screw for the first time.
