The revolutionary and race-proven OS Giken Super Lock is now available for the Scion FR-S and Subaru BRZ!

2013 Scion FR-S2

The OS Super Lock LSD is the culmination of years of extensive research and development that led to a revolutionary LSD design with the capacity to house an unprecedented number of friction plates (up to 28 plates in total). Combined with OS Giken’s patented lock timing system, the Super Lock LSD is able to achieve complete lock in a progressive, smooth, and quiet manner, making it outstanding for both street and racing performance.
