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.

The ATB units are designed using the latest CAD techniques and CNC machined to ultra-tight tolerances from high quality Corus steel billets. The completed units are then subjected to rigorous in-house inspection with 3D coordinate measuring machines. Such quality means that, unlike a conventional plate-type LSD, the Quaife ATB unit requires no special maintenance or rebuilds, is long-lasting, and retains the standard method of lubrication, making for an easy, pain-free upgrade.

Unique, Quaife patented design prevents complete loss of drive that occurs with some conventional differentials when one wheel slips

Never locks, inherently safe
