Quaife ATB Differential
The highly regarded Quaife differential is an excellent modification proving to be far more reliable than the standard OE differential. The Quaife is superior to the Q2 differential although they work in the same way the Quaife differential is made from better quality materials. We can fit the Q2 differential if preffered although it is more expensive.

"Quaife ATB Helical LSD differential for Alfa Romeo. A direct replacement for the standard Alfa Romeo open differential, the Quaife ATB Helical LSD differential transforms your car’s performance.
Unlike a conventional plate-style limited slip differential, the Alfa Romeo Quaife Helical LSD ATB differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.
The Alfa Romeo Quaife ATB Helical LSD differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the Alfa Romeo Quaife ATB Helical LSD differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.
The Alfa Romeo Quaife ATB Helical LSD differential has many benefits over a standard open differential, including maximising traction and minimizing wheelspin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication.
The Alfa Romeo Quaife ATB Helical LSD differential is proven in circuit and drag racing, rallying and road use, and is produced from Corus steel billets, and is CAD designed and CNC machined, then inspected to ISO 9001 standards.
With over 370 applications, the Quaife ATB Helical LSD differential is second to none. Accept no imitations!
