Quaife LSD for Focus ST225

Ford Focus ST225 M66 Quaife ATB Helical LSD differential

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.

The Ford Focus ST225 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.

The Ford Focus ST225 M66 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 170 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 ST225 M66 is also now subject to a lifetime warranty (subject to terms and conditions).

Optional Replacement TIMKEN Bearings

When fitting your LSD you can either re-use the existing standard bearings and races, or we recommend you replace with new. We can supply Timken Bearings and Races as an option on this product. Unlike the standard bearings which have plastic cages, these are high speed rated with steel cages. This option includes two new diff bearings and races, and is included FREE when you choose our optional fitting. If you're opting for our fitting service then you don't need to add the Timken bearings as an option below!
