Tesla Model S Quaife ATB Helical LSD for Large Drive Unit
Limited Slip Differential for Tesla Model S Large Drive Unit
Quaife ATB Helical LSD differential for the
Tesla Model S.
The QDH2T is a direct replacement for the standard open differential in the Tesla Model S.
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 minimizing wheelspin, 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.
