Description

The OS Giken SuperLock Clutch-Type LSD uses our patented thrust ring design that allows for 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 precision machined on both sides simultaneously to extremely close tolerances, resulting in minimal warpage.
• The housing of the limited slip differential is milled from one solid piece to ensure uniformity.

The standard specification of the OS Clutch-Type LSD allows for low preload while still maintaining a fully progressive 100% locking function. Operation is quiet and the progressive locking ensures smooth, predictable locking action. When replacing an open differential, equipping it with an OS Clutch-Type LSD will completely improve the driving experience, while maintaining everyday usability.

Adjustment options

If your application delivers significantly more power, we offer additional adjustment services for your new/used Clutch-Type LSD in-house. More power usually means a greater 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 precisely adjusted to the vehicle/driver
• Incline angles can be adjusted by exchanging the thrust ring and iron cross for even more adjustment options
• TCD specification plates can be installed for improved oil cooling and even smoother operation
