Mercedes C63 AMG QUAIFE ATB limited slip differential

The popular Quaife ATB mechanical limited-slip differential upgrade for the Mercedes C63 AMG is available exclusively at Birds Garage.

The Quaife ATB limited-slip differential offers a guaranteed, superior traction solution for powerful rear-wheel drive road cars. Once installed, drivers will notice an immediate difference as the Quaife LSD automatically biases the torque across the axle to the wheel with the most grip. Unwanted wheelspin and slip are greatly reduced, the car becomes much more controllable during oversteer, and it's able to transfer its power to the tarmac with maximum effect.

Unlike conventional clutch-plate limited slip differentials, there are no clutches, ramps, springs or other components that wear out and require maintenance. Quaife's helical gear system is designed and guaranteed to last the life of the car. The design allows for a progressive and intuitive transition in moments of oversteer, compared to clutch-plate differential that lock and can be known to 'snap' out of turns, making it a favourite for RWD road cars such as the Mercedes C63 AMG.

The Quaife is guaranteed to work flawlessly with all of the standard Mercedes electronics and equipment (the Quaife will not affect any other components on the car) and it comes with its own limited lifetime warranty.
