- What kind of limited slip differential is this?

This is a Clutch-Type LSD, which can be roughly compared to the ZF limited slip differentials as supplied in the BMW M3, M4 GT4, Porsche 911 GT3 RS or Nissan GTR 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, the disadvantages of a traditional sperdiff have disappeared. However, this high-quality technology has its price.

- Can it be compared to a Quaife or other Torsen?

Partially. This limited slip differential 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 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, while with a Quaife you can sometimes be unpleasantly surprised. In addition, the superlock is very suitable for drifting and a Quaife or other twists are considerably less suitable

- Wat is OS Giken?

OS Giken is a high-tech originally Japanese company that specializes in tuning engine blocks, high-quality clutches, differentials and gearboxes. It is very famous in Japan 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 running the diff 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 advantages 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.

An OS Giken limited slip differential guarantees better stability and grip for every type of car. Rear-wheel drive, front-wheel drive, four-wheel drive. Rear, front or middle engine, we will help you determine the correct configuration.
