Quaife QDF36R ATB differential Audi TTRS, RS3, RSQ3 2.5 20v TFSI 5 cyl. (EA855, EA855 evo) DQ500 gearbox (front)

For: Audi TTRS, RS3, RSQ3 2.5 20v TFSI 5 cyl. (EA855, EA855 evo) 4WD with 7-speed DQ500 gearboxes

Backed with the peace of mind of a lifetime warranty, the Quaife ATB helical gear limited slip differential is fully automatic and progressive in operation and unlike plate style units the Quaife ATB never locks, but seamlessly and smooth transfers power and torque away from a spinning wheel to the wheel enjoying the most traction.

In practice this significantly reduces torque steer, understeer and steering ‘snatch’ in front wheel drive applications compared to a plate style limited slip differential.

On the road and track this translates into reduced wheelspin and torque steer, less understeer during cornering and improved straight line acceleration. On the track the Quaife ATB cuts lap times dramatically and improves standing quarter performance.

Perfectly suited to high power front drive cars, but equally at home in rear and four wheel drive vehicles, the Quaife ATB helical gear limited slip differential is a direct replacement for the original factory ‘open’ unit and requires no special oils or servicing.

Successfully used in all forms of motorsport including F1, rallying, circuit racing, truck racing, rallycross and drifting, the Quaife ATB helical gear limited slip differential has been chosen by Ford, General Motors and Daimler-Chrysler as original equipment fitment on some of the finest high performance front wheel drive passenger cars of recent years.
