Description

The OS Giken SuperLock Limited Slip Differential uses our patented thrust ring design that provides smooth, progressive locking. This design is a design with the keyway through the side gear, allowing more friction plates (up to 2x as many as competitor versions) to be fitted. 

• All components are chemically heat treated for maximum durability
• All components are constructed from high-quality steel alloy
• Gears are rough forged for maximum strength
• Friction plates are precision machined on both sides simultaneously to extremely close tolerances, resulting in minimal warpage.
• The Limited Slip Differential Housing is milled from a single solid piece to ensure uniformity.

The standard specification of the OS Limited Slip Differential allows low preload whilst maintaining a fully progressive 100% locking capability. Operation is quiet and the progressive lock provides smooth, predictable locking. When replacing an open differential, installing an OS Limited Slip Differential will completely improve the driving experience, while maintaining daily usability.

Tunability

If your application delivers significantly more power, we offer additional tuning services for your new/used Limited Slip Differential in-house. More power usually means more load on the differential. We have the ability to speed up or slow down the differential action to allow the vehicle to achieve maximum traction.

• The initial torque can be adjusted by using thicker/thinner conical springs
• The timing of the lock progression can be adjusted by using stiffer/weaker compression ring springs, allowing the full lock progression to be fine-tuned to the vehicle/driver
• Lean angles can be adjusted by swapping the thrust ring and iron cross for even more tuning options
• TCD specification plates can be installed for increased oil cooling and even smoother operation
