OS Giken now proudly introduces the OS Super Lock LSD after 3 years of research and development. This limited-slip differential is derived from experience of automotive drive train engineering since the 1980's.
It has unique and epoch making-making technologies with adjustable lock timing adjuster. Incredibly durable and reliable, as only the best materials are used for this LSD, regardless of the production cost. Gears are all hot forged, which improves the precision of the product. It also enables each gear to miniaturize, thus providing more space for friction plates. US patent pending bevel gear-in-pressure ring mechanism also allows more friction plates. Increased number of friction plates improves the locking force of the LSD, as it generates less heat, resulting in higher durability even in the toughest racetrack environment.
The higher locking force prevents a weaver action of the vehicle at the drag strip while its bevel gear-in-pressure mechanism allows easier drive feel, close to an OEM diff, during ordinary operations such as parking the car. This mechanism brought another favorable characteristic: it reduces the impact when the power load is applied, preventing the sudden traction change during cornering, or a sudden pop, making it easier to trace the line. It also produces less mechanical clicking noises.
