Quaife LSD for 3000GT/Stealth VR4 / TT - AWD - FRONT Differential

Quiafe LSD - Limited Slip Differential
3S AWD - FRONT

One way to help get more power to the ground is make sure your tires are not spinning and wasting that power! Quaife LSDs do just that - keep both wheels putting the power equally to the ground.

This is for the ALL-Wheel-Drive Stealth TT and 3000GT VR-4.

3SX worked directly with Quaife to have the speedometer gear machined and INCLUDED with you LSD, already installed.

 

Direct from the Quaife Page:

The Quaife torque biasing differential enables your car to accelerate quicker and corner faster. How?

By getting the power to the ground!

The Quaife Differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential, standard on most cars, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip (along the path of least resistance). The Quaife, however, does just the opposite. It senses which wheel has the better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

In drag-race style, straight-line acceleration runs, this results in a close to ideal 50/50 power split to both drive wheels, resulting in essentially twice the grip of an ordinary differential (they don't call open diffs "peglegs" for nothing).

In cornering, while accelerating out of a turn, the Quaife biases power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.

The Quaife also controls loss of traction when the front wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The Quaife Differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs.

The Quaife's unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage whether on the track or on the street.

The Quaife is extremely strong and durable and since the Quaife is gear operated, it has no plates or clutches that can wear out and need costly replacement.

The Quaife is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that created unwanted understeer under power, or in the case of front-drive cars, even tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the car's limits.

The Quaife has been proven in everything from SCCA Rally to Formula 1. It provides autocrossers with such an advantage, it has become "required" equipment for a winning effort.

More and more auto manufacturers are specifying the Quaife ATB Differential as original equipment in their high performance models - for good reason - it works!

The Quaife ATB Differential comes with something else other's don't have:
a Limited Lifetime Warranty. This warranty applies even when raced!

 

General Product Questions

What sort of gear lube should I use ?

For QUAIFE ATB Differentials:
When running a QUAIFE ATB Differential in a standard transaxle gearbox, we recommend that you use whatever your vehicle's manufacturer recommends. The QUAIFE ATB Differential does not require any special lubricants.
When running QUAIFE gearbox internals and a QUAIFE ATB differential – we recommend Silkolene SYN5 75W90.

For a QUAIFE ATB differential, running in a rear axle – use a hypoid 90 or 75W90, as above.

For those applications that will accept a GL5 or SAE75W90 gear oil, we recommend and sell Silkolene SYN5 75W90 gear oil. We use Silkolene in all our own QUAIFE racing transmissions.

--------------------------------------------------------------------------------

What sort of gear lube should I use with my Quaife Gearbox or Gearkit?

We recommend and sell Silkolene SYN5 75W90 gear oil. It is GL4 and GL5 compatible and is suitable for both synchromesh and dog-engagement transmissions. We use Silkolene in all our own QUAIFE racing transmissions.

--------------------------------------------------------------------------------

What is the torque bias ratio of the Quaife differential?

QUAIFE does not specify bias ratio details and generally, does not use the term. The QUAIFE ATB differential is an all helical gear design. The angle and tooth form of the helix used, the number of pinions used, and many other factors (including the particular car fitted) all contribute to how the differential behaves and biases drive torque. Each QUAIFE differential application is designed to offer the best compromise between performance and durability.

--------------------------------------------------------------------------------

What kind of horsepower can the Quaife differential handle?

The QUAIFE differential is engineered to take just about as much horsepower as you can throw at it. In almost any given transmission or rear axle, the QUAIFE ATB Differential will not be the limiting factor. If you have any questions regarding this, please feel free to contact us.

--------------------------------------------------------------------------------

What sort of maintenance is required when using a Quaife differential?

There is no additional maintenance required when using the QUAIFE differential. You can simply "forget" about it, and let it do its magic!

--------------------------------------------------------------------------------

Are there any special parts needed to install a Quaife differential?

There are no special parts required to install a QUAIFE differential, beyond what may normally be needed to install a stock unit. The basic parts needed will be: differential bearings, transmission or rear end gaskets, and possibly some shims if required.
