OS Superlock limited slip differential
- What kind of LSD is this?
It is a
plate type lsd, which can be roughly compared to the ZF limited slip differentials as supplied in the BMW M3 E36, M4 GT4, Porsche 911 GT3RS or Nissan GTR, for example.
- Why is this differential more expensive than most torsen and used limited slip differentials?
This is a new limited slip differential, not a rebuild one. The best techniques and materials have been used, the disadvantages of a traditional and cheaper plate type LSD's have been resolved and the construction in more complex than a torsen.
- Is it comparable to a Quaife?
Partially. This LSD is also maintenance-free. However, much more is possible in terms of adjustment, the differential also locks with 1 wheel off the ground (unlike a Quaife) and it also locks during braking/deceleration. In addition, blocking action of up to 100% is possible, so more power can be transferred to the road surface. And there will be noticeably better stability in your car with an OS Giken where you can sometimes be unpleasantly surprised with a quaife. In addition, the superlock is very suitable for drifting and a Quaife is not the ideal solution.
The big advantage for the OS Giken being a plate type LSD is that it is controlled by throttle imputs and therefor directly connected to driver imputs, This makes for a confidence inspiring LSD where e-diffs, torsens, visco lsds and too softly setup differentials are very much depending on tyre grip changes which are hard to predict for the driver.
- What is OS Giken?
OS Giken is a high-tech originally Japanese company that specializes in tuning engines and supplies high-quality clutches, differentials and gearboxes, among other things. It is very famous in Asia and America, in Europe mainly for Asian brands such as Nissan.
- Why this limited slip differential?
Design can handle more power
Locking effect up to 100%, but without the disadvantages that normally occur with 100% blocking effect
No maintenance required, the plates hardly wear out. There are racing teams that have been driving the diff for 10 years without any problems and have only changed the oil.
Adjustable acceleration/deceleration locking action
Due to the setup possibilities and the 100% lock you can expect better lap times or more controllable drifts. The differential can also be adjusted in such a way that it can be driven on public roads. It will have the benefits of an open differential at slow speeds, and the grip of a racing limited slip differential when you step on it.
Central springs / negative preload (yellow box drawing)
The big technical advantage for the Superlock lies in the central springs that pull the pressure rings (which create the pressure on the clutch plates ) AGAINST each other. In fact, these springs ensure that there is little locking effect when driving slowly, parking, or steering in (braking). When accelerating, this spring force will be overcome, and the differential will lock.
The differential has been proven by professional teams around the world in rally, racing and drifting. We support customers in europe with Ring records, endurance racing, drifting and rally championships
