The redesigned QDF9V-2 features larger internal gears for more overall strength and increased power holding capacity. The new QDF9V-2 is designed to replace the OEM open differential in 300C, Charger, Challenger, and Magnum applications with the “215” rear axle, however, the new larger case prevents OEM fitment in crossover Mercedes applications. Modifications to the differential carrier are necessary to fit the QDF9V-2 in Mercedes applications, though if desired, Mercedes customers are still able to purchase the original QDF9V-1 for OEM fitment.
AS ENGINE POWER outputs increase ever further, the ability to utilize this extra performance becomes more important. Wheelspin may look spectacular, but such losses of traction waste time either from a standing start or exiting a bend, whether driving on the road, circuit, rally stage or drag strip. Fortunately, QUAIFE’s patented Automatic Torque Biasing (ATB) Helical LSD differential is an effective, well-proven, low-cost solution.
As a direct replacement for the standard, factory ‘open’ differential, QUAIFE’s ATB Helical LSD unit can transform the performance of your car. Unlike a conventional plate-style limited slip unit, QUAIFE’s ATB Helical LSD unit relies on gears, rather than clutch plates for its operation.
That means it’s much smoother in operation, because unlike a conventional plate-style LSD, it never locks harshly with a set pre-load of wheel slip across the driven axle. Rather, it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree and never locks.
To the driver (especially of a front-wheel drive car,) the results are significant performance improvements;- superior, controllable traction without the harsh steering wheel snatch or torque steer that have long been associated with performance differentials. These traction benefits can also be utilized in rear wheel drive vehicles, while QUAIFE ATB Helical LSD units offer significant traction advantages fitted to the front of four wheel drive cars.

Reliability is total; the ATB Helical LSD units are designed using the latest CAD techniques and are CNC machined to ultra-tight tolerances from the very best CORUS steel billets. The completed units are then subject to rigorous in-house inspection on a tri-coordinate measuring machine before being dispatched to the customer.
Such quality means that unlike a conventional plate-style LSD the QUAIFE ATB Helical LSD unit requires no special maintenance or rebuilds, long lasting and it retains the standard method of lubrication, making for an easy, pain-free upgrade.
Proven in rallying, racing and on the road, the ATB Helical LSD differential offers safe, reliable, winning performance – everything you’d expect from a QUAIFE product.
