Quaife limited slip differential for VAG 02Q and MQ350 6 speed 2 Wheel drive gearboxes

A direct replacement for the standard open differential, the Quaife ATB differential transforms your car’s performance.

Unlike a conventional plate-style limited slip differential, the Quaife ATB differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.
