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