Product Details

The OS Super Lock LSD is the culmination of over four 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 our patented lock timing system, the Super Lock LSD is able to achieve complete lock in a progressive, smooth, and quiet manner, making it suitable for both street and racing performance.

Superior Design

Miniaturized pressure ring and a superior spline-through-side-gear design allows for fitment of more friction plates (up to 2x as many as competitors versions), offering true 100% lock capability

Patented pressure ring design allows for smooth, progressive locking

LSD case has a relief cut-out for the cone spring, resulting in minimal cone spring degradation and enhanced durability

Superior Construction

All components are chemically heat treated for maximum durability

All components are constructed from a high-grade steel alloy Gears are raw-forged for maximum strength

Clutch disks are precision-machined simultaneously on both sides to extremely tight tolerances resulting in minimal warpage

LSD case is machined from a single billet piece to ensure uniformity

Superior Overall Performance

The OS LSD standard spec allows for low preload while still retaining a fully progressive 100% lock capability; basically, the vehicle will feel like driving on an open diff in slow turns / street driving, but can still transmit maximum power to the drive wheels under load
