Looking for a grippy upgrade to your weekend track or road car? Look no further, OS Giken USA offers a wide variety of custom build limited slip “Super Lock” differentials for the abuse of any purpose that your 305Z or Honda S2000 may have. 

The OS “Super Lock” LSD is stated to be the culmination of over four years of extensive research and development leading to a revolutionary LSD design. The units can hold up to 28 friction plates, and have a combined patented lock timing system designed by OS Giken, they state the “Super Lock” LSD is able to achieve complete lock in a progressive, smooth, and quiet manner – which translates to quick lap times and repeatable tuning and performance.

Features include:

  • 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.

Plus, 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.
