Quaife ATB Helical LSD differential for Porsche 911 1969-74 is suitable for Porsche 911 models in model year 1969-74 only. A direct replacement for the standard Porsche differential, the Quaife ATB Helical LSD differential transforms your car’s performance.

Unlike a conventional plate-style limited slip differential, the Porsche 911 1969-74 Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.

The Porsche 911 1969-74 Quaife ATB Helical LSD differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the Porsche 911 1969-74 Quaife ATB Helical LSD differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.

The Porsche 911 1969-74 Quaife ATB Helical LSD 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 Porsche 911 1969-74 Quaife ATB Helical LSD 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.
