The Quaife ATB Helical LSD differential for the Caterham (De Dion axle) fits a variety of vehicles using a 7" Sierra differential casing.
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).
