Quaife Engineering - Torque Biasing Differential - 020 Transaxle


Quaife engineering is the originator of the Helical Torque Biasing limited slip differential, often imitated, but never equaled in engineering knowledge and performance. Please note, does NOT come with bearings or a bolt kit. Please purchase these items separately, or contact for more information.

Quaife ATB Helical LSD differential for Volkswagen 020 is suitable for Volkswagen models with 020 gearbox, such as all Mk1, Mk2 and Mk3 2.0 8v cars. A direct replacement for the standard Volkswagen open differential, the Quaife ATB Helical LSD differential transforms your car's performance.

Unlike a conventional plate-style limited slip differential, the Volkswagen 020 109mm Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation. you will see improved traction, minimized wheel spin, less torque steer, as well as sharper turn in and improved handling when putting power down through the corners. Limited lifettime warranty!

The 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 it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.

The Volkswagen 020 109mm 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.

Quaife have learned a huge amount from all of the years in business. This has been enhanced by the hands-on approach to developing Quaife products and technology through racing. Testing and developing Quaife products through motorsport has always been a key part of the business,  since the early days of R.T. Quaife Engineering. The rich heritage of success in competition includes innumerable race victories and championship successes all over the world, not only on four wheels but also two wheels, and both on race circuits and off road.

Over 35,000 Quaife ATB Helical LSD differential units have already been sold as original equipment, and the clean warranty record complements the quality of the product itself. This is of course supported by Quaife's ISO 9001 approval. This covers every use from utility vehicles, to road cars, to track cars, to rallying, racing and drag racing, and no doubt many other uses. In addition, Quaife has worked with many top manufacturers for sporting performance models of their own cars, and as a global OEM supplier, you can count on Quaife as the best part available for your car!
