Description
OS Giken utilized its accumulated racing knowledge and engineering experience to develop its own limited slip differential. Four years of extensive research and development lead to a new and revolutionary LSD design with the capacity to house an unprecedented number of friction plates (up to 28 plates in total) and thus the OS Super Lock LSD was born. The increased number of plates directly has not only dramatically improved our LSD design's locking force and enables it to lock fully and completely. An added benefit to being a fully locking mechanism is that less heat is generated, thus resulting in incredible durability and reliability.
As expected from OS Giken, our LSDs are not only made from the highest quality materials, our precise machining, forged gears, and sound engineering makes our LSDs the most durable and reliable race performance LSDs available.
In addition, our design allows for the initial torque setting and lock timing to be customized to best fit you vehicle's everchanging set-up and course/road conditions. (Limited to Spec-X LSDs only).
****ATTENTION: 370Z requires modification or side flanges to be replaced. The replacement Flange part # from Nissan is: 38220-JK01B*****
What is the difference between an OS Giken SUPER LOCK LSD and another companies LSD?
In racing applications, the function of the LSD is to allow the drive wheels to apply equal traction under acceleration and deceleration. Unlike our competitors' products, the OS Giken SUPER LOCK LSD is engineered to be extremely responsive to throttle input to smoothly lock or loosen accordingly. Through its innovative and patented design, up to twice as many friction plates are able to fit into the housing when compared to our competitors' products, enabling the OS Giken SUPER LOCK LSD to achieve true 100% locking capability. Unlike our competitors, the OS Giken SUPER LOCK LSD is also customizable by adjusting the spring inside the pressure ring. Additionally, its superior design allows for excellent streetability, virtually eliminating the “chatter” associated with other clutch type LSD brands. Each component of every OS Giken SUPER LOCK LSD uses only the highest grade materials and manufacturing processes and is constructed and finished to extremely tight tolerances, eliminating any “break-in” period necessary with other brands. Due to its superior design and extreme care throughout the manufacturing process, there has yet to be a case recorded of an OS Giken SUPER LOCK LSD failing in the field, or even requiring a rebuild!
OS Giken SUPER LOCK LSD advantages :
.:. A true 100% locking LSD: No movement of internal parts means less heat is generated while in operation and less wear of the friction disks. Less initial torque loss and incredible longevity and durability can be realized.
.:. Proven Durability and Reliability: No drop in performance or loss of initial torque, even during long and stressful endurance races.
.:. Straight line stability: During a drag race, our LSD will lock 100% and provide torque equally to each powered wheel. Stable and straight runs will result thus eliminating torque steer in FF applications and lower the chance of drive-shaft breakage.
.:. Customizable: Lock timing can be customized by adjusting the spring inside the pressure ring. Tune the LSD to custom fit any application and set-up of your desired vehicle and driving style/skill level for optimum performance.
.:. By using a pressure control ring, the LSD responds smoothly to the application of initial torque. Lock engagement is smooth and the impact vibration is significantly reduced. This increases the stability of the vehicle and allows more freedom for the driver to trace the desired racing line.
.:. On snow tracks and regions with unstable road conditions, our OS SUPER LOCK LSD easily adapts and adjusts tire rotation to increase vehicle stability. Bad weather and harsh road conditions are not a problem when the vehicle is equipped with an OS SUPER LOCK LSD
.:. Less under-steer during cornering: When entering into a corner with the throttle closed, the spring inside the pressure control ring will react accordingly and immediately return the differential's internal components to the original initial torque settings and thus creating less under-steer. However, with a conventional differential, there will be a lapse of time before returning to the initial torque settings, as it takes time for the cone springs to react and make contact with the friction disk in order to close the pressure ring.
.:. When exiting from a corner, our LSD's transition to the full 100% lock position is smooth and predictable. This gives the vehicle better traction and stability, resulting in better lap times while racing.
.:. OS Giken SUPER LOCK LSDs do not require any break-in process. OS SUPER LOCK LSD's are composed of parts that have been precisely machined to exact specifications and are ready to use upon installation.
