Description

The OS Giken SuperLock Limited Slip Differential uses our patented thrust ring design that enables smooth, progressive locking. This design is a spline-through side gear design that allows for the installation of more friction plates (up to 2x as many as competitor versions). 

• 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 precisely machined on both sides simultaneously to extremely close tolerances, resulting in minimal warpage.
• The limited slip differential housing is milled from a single billet piece to ensure uniformity.

The standard specification of the OS Limited Slip Differential ensures a low preload while maintaining a fully progressive 100% locking effect. Operation is quiet and the progressive lock ensures smooth, predictable locking action. When replacing an open differential, equipping it with 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 so that the vehicle can achieve maximum traction.

• 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 progression to full lock action to be fine-tuned to the vehicle/driver
• Ramp angles can be adjusted by swapping the thrust washer and iron cross for even more adjustment options
• TCD-spec friction plates can be installed for increased oil cooling and even smoother operation
