Description

The OS Giken SuperLock Limited Slip Differential uses our patented thrust ring design that provides smooth, progressive locking. This design, with a spline-through side gear, allows 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 made of high-quality steel alloy
• Gears are rough forged for maximum strength
• Friction plates are simultaneously precision machined to extremely close tolerances on both sides, resulting in minimal warpage.
• The limited slip differential housing is milled from one solid piece to ensure uniformity.

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

Adjustability

If your application requires 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.

• 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
• Ramp angles can be adjusted by exchanging the pressure ring and the 'iron cross' for even more tuning options
• TCD-spec discs can be installed for improved oil cooling and even smoother operation
