The Quaife ATB Helical LSD differential transforms your car's performance.Unlike a conventional plate-style limited slip differential, the Quaife Helical ATB differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.


The Quaife ATB differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.


The Quaife ATB differential is proven in circuit and drag racing, rallying and road use, and is produced from Corus steel billets, and is CAD designed and CNC machined, then inspected to ISO 9001 standards.
