Quaife Birkin LSD Diff ATB Limited Slip Differential Kit

The Quaife ATB Helical LSD differential transforms your car’s performance
Unlike a conventional plate-style limited slip differential, the Birkin S3 Roadster Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation

That means it is much smoother in operation
The Birkin S3 Roadster 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 Birkin S3 Roadster 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 Birkin S3 Roadster 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 Birkin S3 Roadster 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
With over 370 applications, the Quaife ATB Helical LSD differential is second to none

Accept no imitations!, Quaife ATB Helical LSD differentials are used by Ford, General Motors and Daimler-Chrysler as original equipment
The Quaife ATB Helical LSD differential for Birkin S3 Roadster is also now subject to a lifetime warranty (subject to terms and conditions)
