Maximize traction and performance with the Quaife ATB helical limited slip differential. The Quaife ATB differential transforms your car's performance and improves cornering. Unlike a conventional plate-style limited slip differential, the Quaife differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation and never locks harshly with a set pre-load of wheel slip across the driven axle. Instead, the Quaife differential automatically biases the torque away from the spinning wheel, across the axle to a constantly varying degree.

Benefits over a standard open differential:

  • Maximize traction
  • Minimize wheel spin
  • Reduced 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
  • Quaife Automatic Torque Biasing Differential - Track Tested and Proven
