The 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 LSD will completely improve the driving experience while maintaining everyday drivability.
