OS Giken SuperLock LSD | 04-15 Mazda Miata (NC) | 2.0L camshafts This revolutionary design dramatically improvesThe OS Giken Super Lock LSD uses our patented pressure ring design that allows for smooth, progressive locking. This design is a spline through side gear design that allows for fitment of more friction plates (up to 2x as many as competitors versions). The OS LSD standard spec allows for low preload while still retaining a fully progressive 100% lock capability. Operation is quiet and the progressive locking allows for smooth predictable locking. OS
