Quaife Caterham DeDion axle LSD ATB Differential

The Quaife ATB Helical LSD differential for the Sierra 7" fits a variety of vehicles using a 7" Sierra differential casing, and is available in 2 different helix angles to suit different applications
The standard helix angle suits the Ford Sierra and other saloon cars using the Sierra 7" rear differential
The 23 degree helix angle is designed for use light weight RWD cars such as the Caterham 7, where use of the standard helix angle would be too aggressive and cause the car to "push on" in corners
Optional Quaife drive flanges are available if using the Ford bolt on drive shafts, otherwise the standard push in drive shafts will fit straight in
A direct replacement for the standard open differential, the Quaife ATB differential transforms your car’s performance

Unlike a conventional plate-style limited slip differential, the 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 ATB differential has many benefits over a standard open differential, including maximising traction and minimizing 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 Quaife ATB differential is proven in circuit and drag racing, rallying and road use, and is produced from Corus steel billets, CAD designed and CNC machined, then inspected to ISO 9001 standards
With over 370 applications - the Quaife ATB differential is the best option to utilise your car's performance
Quaife ATB Helical LSD differentials are used by Ford, General Motors and Daimler-Chrysler as original equipment
The Quaife ATB Helical LSD differential is also now subject to a lifetime warranty (subject to terms and conditions)
