The OS Giken Super Lock TCD is a Super Lock limited-slip differential specified for Porsche 997 Twin Turbo and Cayman S PDK models. Built for precise traction control in high-power applications, this unit replaces the standard differential to improve drivewheel grip under varying loads. Fitment is explicit to those Porsche applications, providing a drivetrain upgrade without assuming compatibility beyond the listed models.
