Product Description

Quaife ATB Helical LSD differential for the Tesla Model S/X Large Drive Unit. The QDH2T is a direct replacement for the standard open differential in the Tesla Model S Large Drive Unit.

This is a must have for any EV build using a Tesla drive unit and we recommend it as standard in all of out Drive units.

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.

The 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 ATB differential has many benefits over a standard open differential, including maximising traction and minimising wheel spin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication.

The 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. The Quaife ATB differential is also now subject to a lifetime warranty (subject to terms and conditions).
