Maximize traction and performance with the Quaife ATB helical limited slip differential. A direct replacement for the standard open differential, the Quaife ATB differential transforms your car's performance and improves cornering. Unlike a conventional plate-style limited slip differential, the Quaife ATB differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation and never locks harshly. Instead, the Quaife ATB differential automatically biases the torque away from the spinning wheel, across the axle to a constantly varying degree.
-Minimize wheel spin
-Reduce torque steer and snatching in front wheel drive cars
-Maintenance-free design which retains the standard oil lubrication
Quaife differentials are proven in circuit and drag racing, rallying and road use
All Quaife differentials are produced from Corus steel billets, and are CAD-designed and CNC machined before being inspected to ISO 9001 standards
