The new OS Giken Super Lock TCD differential is an advanced LSD design, offering exceptionally smooth transition from open to locked operation. The unique design uses oil distribution channels on the plate surfaces and through the cartridge to achieve strong locking without the jerky low-speed operation often associate with mechanical LSD centers. The design is also maintenance-free thanks to the improved lubrication.
After four years of extensive research, OS Giken utilized its accumulated racing knowledge and engineering experience to develop the Super Lock TCD (Traction Control Differential). This advanced LSD uses a revolutionary breakthrough in clutch-type differential design. Its patented design enables 100% full locking, unparalleled durability and allows up to twice the friction plates (up to 28 plates in total) compared to conventional designs.
Made from the highest quality material using precise machining, forged gears and sound engineering, the Super Lock systems are the most durable and reliable race performance LSDs available. The Super Lock TCD is a 1.5-way differential that locks fully under acceleration and only partially under braking. However, because of the unprecedented amount of friction plates, this system results in reduced wear and more progressive locking action thus improving the ability for the LSD to lock fully and completely. And because of their fully locking design, less heat is generated resulting in even further durability and reliability.
In addition, for the Mercedes vehicles, the Super Lock TCD has utilizes specialized machining in the clutch plates and side gears to channel oil onto the plate surfaces and cartridge. This functions virtually like an oil pump and is designed to ensure quiet operation and maintain a more luxury feel.
Maintenance is very worry free with the Super Lock TCD as there is no break-in period required and no need to rebuild the unit.
The Super Lock TCD is a best of breed product. It is as smooth as an open diff at low speeds (no diff chatter), but still able to lock up to 100% under throttle.
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 competiting 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 competiting products, enabling the OS Giken SUPER LOCK LSD to achieve true 100% locking capability. Unlike 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, the Super Lock 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, the 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 internal components of the differential 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, the LSD 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 LSDs are composed of parts that have been precisely machined to exact specifications and are ready to use upon installation.
