The GKTECH Solid Aluminium Steering Rack Bushings are a direct replacement of the OEM rubber bushings. The OEM rubber bushings are prone to high loads, especially on a track/ drift car. Our aluminium bushings leave no margin for play and are CNC machined from billet aluminium and replace all of the bushings in the steering rack. Vehicle Compatibility: - Nissan Z34 370z - Infiniti G37
