Ford Focus ST170 Quaife ATB Helical LSD Differential
Quaife ATB Helical LSD differential for Ford Focus ST170 is suitable for Ford Focus ST170 using the Getrag 6 speed gearbox. A direct replacement for the standard Ford open differential, the Quaife ATB Helical LSD differential transforms your car's performance. Unlike a conventional plate-style limited slip differential, the Ford Focus ST170 Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation. The Ford Focus ST170 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 Ford Focus ST170 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 Ford Focus ST170 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 Ford Focus ST170 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 Ford Focus ST170 is also now subject to a lifetime warranty (subject to terms and conditions).

The QUAIFE ATB differential is designed to prevent the complete loss of drive that occurs with a conventional differential when one wheel slips. Whilst requiring some torque in the slipping wheel, the QUAIFE unit is progressive in action but never locks – controlled power is transmitted to all the driving wheels.
Ideally suited to high powered front wheel drive systems, QUAIFE ATB differentials are also used in rear and four wheel drive vehicles where optimum traction is required. Installation is identical to the normal differential with bearing pre-loads and pinion mesh being restored to the original manufacturers’ settings. Servicing of the unit is simple as all gear pinions are free fitting and normal final drive lubrication oils are retained.
