The OS Superlock differntial lock

Super 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. The case has a relief cut-out for the cone spring, for minimized cone-spring flexing and enhanced durability.

 

 

 

 

 
Superior Construction
All components are chemically heat treated for maximum durability. All components are constructed with high-grade steel alloy. The  gears are raw-forged for maximum strength. The disks are precision-machined simultaneously on both sides to extremely tight tolerances. And case is billet construction.

Tunabililty
The Initial torque can be adjusted by using thicker / thinner cone springs. Lock progression timing can be adjusted by using stiffer / weaker pressure ring springs. Ramp angles can be customized by swapping the pressure ring and iron cross. The disks can be swapped to TCD type for enhanced oil flow properties.

 

 

 

 

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.

Incredible 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. Operation is ultra quiet, and the progressive locking allows for smooth, predictable locking. Especially when replacing an open diff, equipping OS LSD
will completely improve the driving experience while maintaining everyday drivability. With OS LSD equipped, inside wheelspin can essentially be eliminated, and throttle steering becomes unequivocal.
Due to the precision manufacturing, high-grade materials / processes used, and superior design, no break-in period is required for OS LSD, and no rebuilds are required. OS LSD is purposefully over-engineered to offer the best performing, most durable clutch-type LSD available.
Aside from the performance advantage and stock-like feel at slow speeds, vehicles equipped with OS LSD are more stable in all road/weather conditions, allowing for a safer driving experience.
