ATB Limited Slip Differential

The Quaife QDF32B is an Automatic Torque Biasing (ATB) limited slip differential, engineered to be a direct replacement for the standard factory open differential in many Mercedes-Benz models. This high-performance upgrade is particularly beneficial for powerful Mercedes vehicles, including AMG variants, offering significant improvements in acceleration, cornering speed, and overall vehicle dynamics. By ensuring a controlled power supply to both driven wheels, the Quaife ATB differential provides a more consistent and predictable handling experience, enhancing safety and performance, especially in adverse weather conditions or during spirited driving. The Quaife ATB differential utilizes an all-helical gear design. Its torque-biasing capability is influenced by gear geometry, pinion count, and specific vehicle application, allowing it to seamlessly integrate with existing traction control and ABS systems without requiring special parts for installation. This means you can enjoy the benefits of enhanced traction and stability without compromising your vehicle's advanced safety features. The product is compatible with a wide range of Mercedes-Benz applications, including various C-Class, CLK, CLS, E-Class, S-Class, SL, and SLR models, among others. Specific fitment details, including model years and engine designations, are extensive and available for consultation. Installation typically requires standard differential bearings, transmission or rear-end gaskets, and potentially shims, but no specialized modifications to the vehicle's axle sets are necessary.
