Installation Notes and Tips

Install RK641438 in the rear lower forward position only, following the vehicle-specific service procedure for the Mazda 3, Mazda 3 Sport, or Mazda 5. Because mounting hardware is not included, inspect existing fasteners and replace any damaged hardware as needed. Final torque should be set with the suspension at normal ride height to help protect the rubber bushings.
