Quaife ATB Helical LSD differential for Ford Focus ST225 M66 is suitable for Ford Focus ST225 using the M66 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 ST225 M66 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 ST225 M66 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 ST225 M66 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.
