OS Giken Superlock LSD E36 M3 3.0 / Z3M (188 M14 bouten) (M3B) Superlock M3B

Description

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

• All parts are chemically heat treated for maximum durability.

• All parts are made of high-quality steel alloy.

• Gears are rough forged for maximum strength.

• Clutch discs 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 a single piece of billet to ensure uniformity.

• The standard specification of the OS Limited Slip Differential allows for low preload whilst still maintaining a fully progressive 100% locking capability. 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.

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 "kick" to the differential. We have the ability to speed up or slow down the differential action to allow the vehicle to achieve maximum traction.

• It 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 lockout to be fine-tuned to the vehicle/driver.

• Approach angles (Ramp angles) can be adjusted by swapping the thrust ring and iron cross for even more tuning options.

• TCD specification drives can be installed for increased oil cooling and even smoother operation.
