Ford Focus Mk2 ST225 (6-speed – M66) Quaife ATB Helical LSD differential

Quaife ATB Helical LSD differential is suitable for the Ford Focus Mk2 ST225 (6-speed – M66). A direct replacement for the standard Ford Focus Mk2 ST225 (6-speed – M66) open differential, the Quaife ATB Helical LSD differential transforms your car’s performance.

Unlike a conventional plate-style limited slip differential, the Ford Focus Mk2 ST225 (6-speed – M66) Quaife Helical LSD ATB differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.

The Ford Focus Mk2 ST225 (6-speed – 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 Mk2 ST225 (6-speed – 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.

The Ford Focus Mk2 ST225 (6-speed – M66) 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.
