Quaife ATB Helical differential assembly, complete with reconditioned Ford case & new CWP.
Suitable as a direct replacement for the standard Ford 7" differential assembly, complete with the Quaife ATB Helical differential.
Available in 23 degree helix angle for lightweight sports/kit cars, such as Caterhams, where the standard helix angle would otherwise be too aggressive.
Unlike a conventional plate-style limited slip differential, the Quaife ATB differential relies on gears rather than clutch plates for its operation. This 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, the Ford Sierra 7" 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 Quaife 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 Ford Sierra 7" Quaife ATB Helical LSD 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 is second to none. Accept no imitations!
Quaife ATB Helical differentials are used by Ford, General Motors and Daimler-Chrysler as original equipment.
The Quaife ATB differential is also now subject to a lifetime warranty (subject to terms and conditions).
