Quaife ATB Helical LSD: Chally 6.1L 08-10
Available: In stock
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
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!
