OS Giken Superlock L1 TCD (210 M) BMW LSD

- Wat for LSD is dit?
It concerns one Clutch-Type LSD, this can be roughly compared with the ZF limited slip differentials as supplied 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 new limited slip differential, not a reconditioned one. The best techniques and materials have been used, and the disadvantages of a traditional limited slip differential have disappeared. However, this high-quality technology has its price.

- Can it be compared to a Quaife or another Torsen differential?
Partially. This limited slip differential is also maintenance-free. However, much more is possible in terms of adjustment, the differential also locks with one wheel off the ground (unlike a Quaife) and also locks during braking/deceleration. In addition, blocking operation 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 or other Torsen differential is considerably less suitable.

- Wat is OS Giken?
OS Giken is a Japanese high-tech company that specializes in tuning engine blocks 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
Blocking effect up to 100%, but without the disadvantages that normally occur with 100% blocking effect.
No maintenance is required, the plates hardly wear out. There are racing teams that have been using the differential for 10 years without any problems and have only changed the oil.

Adjustable acceleration/deceleration locking function
Due to the ideal adjustment and the 100% lock, you can expect better lap times or more controllable drifts. The differential can also be adjusted so that it can be driven on public roads. It will have the benefits of an open differential when driving slowly, and the grip of a racing limited slip differential when accelerating.

Central springs / negative preload (yellow box drawing)
The big difference is in the central springs that actually pull the pressure pieces (which exert pressure on the blocking plates) AGAINST each other. These springs actually ensure that there is little locking effect when driving quietly, parking, or (braking) steering. During acceleration, this spring force will still be overcome and the differential will lock.

The differential has been proven by professional teams around the world in rallying, racing and drifting.
