OS Giken Differential

OS Giken Super Lock LSD

The innovative OS Giken Limited Slip Differential combines the advantages of a helical gear type differential with a clutch pack differential. Maximum torque can be transferred to a corner's inside wheel increasing traction and cornering speed. The OS Giken LSD is manufactured using the highest quality materials and technology. A 28 clutch pack with large friction discs allows smooth power transfer and a balanced chassis while allowing the differential to be able to transmit maximum power with minimal power loss due to heat build up.

Differential gears are hot forged which improves strength and allows miniaturization allowing larger clutch friction discs to be used for maximum torque holding capability. Multiple clutch pack allows for minimized mechanical sound during differential lock and dis-lock (although some sound during low speed cornering is typical of a performance designed LSD).

The OS Giken differential also features a US-patented spring lock-timing adjuster which allows for differential locking to be adjusted for different track conditions and configurations.

The OS Giken LSD includes a 4.44 final drive gear set including countershaft, ring gear, and oil pump gear resulting is improved acceleration (increased from the factory 4.06 ratio). This final drive gear set is unique and proprietary to the OS Giken differential. The OS Giken differential is required in order to install the 4.44 final drive.

Available for 5-spd and 6-spd NSX. 1.0, 1.5, and 2.0 way locking configuration is available. 1.5 way allows the best response for off and on acceleration locking for road course use.

The OS Giken LSD and final drive is compatible with all years and will not affect EPS system on later model 6-spd.
