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.

Tunability
Initial torque can be adjusted by using thicker / thinner cone springs
Lock progression timing can be adjusted by using stiffer / weaker pressure ring springs, allowing the progression of full lock to be fine-tuned to the vehicle/driver.
Ramp angles can be customized by swapping the pressure ring and iron cross for even more tuning possibilities.
TCD spec disks can be installed for increased oil cooling and even smoother operation.

Super Lock LSD Spec X
For vehicles that are heavily modified or are particpating in specific forms of motorsports, we offer the Spec-X LSD. The custom order Spec-X is available in 1-way, 1.5-way, and 2-way configurations and can be made with custom cam angles, lock timing, and initial torque settings.

Traction Control Differential (TCD)
The innovative TCD system uses specialized oil channels and pathways to provide maximum oil flow and minimal noise, resulting in exceptionally smooth locking.
