Quaife ATB Helical LSD Differential - Porsche 997

Quaife ATB Helical Limited Slip Differentials are a direct replacement for the standard, factory-fitted open differential and can transform the performance of any vehicle. As engine power outputs increase, the ability to use this extra performance becomes more important. Wheelspin may look spectacular, but such loss of traction from either a standing start or exiting a bend wastes time, whether driving on the road, circuit, rally stage or drag strip. Fortunately, Quaife's patented Automatic Torque Biasing (ATB) Helical Limited Slip Differential (LSD) is an effective, well-proven, low-cost solution.Unique, Quaife patented design prevents complete loss of drive that occurs with some conventional differentials when one wheel slipsNever locks, inherently safeControlled power transmitted to all driving wheelsAutomatic in operationEliminates harsh torque steer and under steering characteristics of other types of LSDGear operated (no plates to wear or break)Direct replacement for standard unitUsed in all forms of motorsport and suitable for road useThe ATB units are designed using the latest CAD techniques and CNC machined to ultra-tight tolerances from high quality Corus steel billets.
