OS Giken dual-core limited-slip differential.
- What kind of limited-slip differential is this?
It is a plate-type limited-slip differential, which is broadly comparable to the ZF limited-slip differentials found, for example, in the BMW M3, M4 GT4, Porsche 911 GT3 RS, or Nissan GT-R Nismo.
- Why is this differential more expensive than most other limited-slip differentials?
This is a brand-new limited-slip differential, not a remanufactured unit. It incorporates the best technologies and materials, eliminating the drawbacks of a traditional limited-slip differential. However, this high-end technology comes at a price.
- Is it comparable to a Quaife or other Torsen differentials?
Partially. This limited-slip differential is also maintenance-free. However, it offers much greater adjustability; the differential locks even when one wheel is off the ground (unlike a Quaife) and also locks during braking/deceleration. In addition, lock-up rates of up to 100% are possible, so more power can be transferred to the road surface. You’ll also notice significantly improved stability in your car with an OS Giken, whereas with a Quaife you might occasionally be in for an unpleasant surprise. Furthermore, the Superlock is highly suitable for drifting, whereas a Quaife or other Torsen systems are considerably less so
- What is OS Giken?
OS Giken is a high-tech company, originally from Japan, that specializes in engine tuning and supplies, among other things, high-quality clutches, differentials, and transmissions. It is very well known in Asia and America; in Europe, it is primarily known for Asian brands such as Nissan.
- Why this limited-slip differential?
The design can handle more power
Locking action up to 100%, but without the drawbacks typically associated with 100% locking
No maintenance required; the plates show virtually no wear. There are racing teams that have been using this diff for 10 years without any issues and have only changed the oil.
Adjustable lock-up during acceleration and deceleration
Thanks to the ideal tuning and 100% lock, you can expect better lap times or more controllable drifts. The differential can also be adjusted so that it’s perfectly suitable for driving on public roads. When driving slowly, it offers the benefits of an open differential, and when accelerating, it provides the grip of a racing limited-slip differential.
The differential has been tested by professional teams around the world in rallying, racing, and drifting.
An OS Giken limited-slip differential guarantees better stability and traction for any type of car—rear-wheel drive, front-wheel drive, or all-wheel drive. Whether the engine is rear-, front-, or mid-mounted, we’ll help you determine the right configuration.
